Build an internal trading desk platform — PostgreSQL + Retool + n8n + Telegram bot

@sptechnocrats

Hello there, The main part of this project is not just building the Retool screens. It is making sure PostgreSQL stays the single source of truth and that pricing, approvals, history, Telegram, and n8n all work together correctly. I can work from your existing technical specification and complete the project within 7 consecutive working days. I will handle the work directly, with no middleman or handoff. I have worked with PostgreSQL functions, views, triggers and migrations, along with Retool, bulk-entry grids, self-hosted n8n, Telegram bots and LLM-based data extraction. I also understand the importance of storing the original Telegram/mailbox messages before parsing them, and testing the LLM extraction against real messages to reach the 95% accuracy target. I can share a Retool example or screenshot. I can also confirm that I can work all 7 days and let you know exactly who will be involved. All code, repositories and accounts can stay in your name from day one. If you share the specification, I can review it and confirm the 7-day plan. Best, Sandeep

Hi there, Your main risk is not building screens, but keeping pricing data trustworthy: PostgreSQL must remain the source of truth, raw messages must be preserved, and every price/deal change needs a clear audit trail. That is the right approach for an internal trading desk. I’m a full-stack developer with strong PostgreSQL/backend experience, including schema design, migrations, triggers, SQL functions, audit history, API integrations, and LLM-based structured extraction. I can implement this around your existing specification without overcomplicating it: versioned migrations first, clean FK-based product/grade normalization, SQL views/functions for margin and search logic, Retool as the operational UI, n8n for controlled workflow automation, and a small standalone Telegram bot service with tests. For the LLM extraction, I would store inbound messages before parsing, validate structured output against your 100-message set, and make Confirm/Fix/Discard safe for operators rather than trying to automate uncertain data blindly. I can work 7 consecutive working days on this, and I would work on it personally unless you explicitly approve otherwise. Code, repos, and accounts can be in your name from day one. I can share relevant internal dashboard examples privately, though I avoid exposing client screenshots publicly.

Hi, I've built LLM extraction pipelines where free-text messages get parsed into structured fields with a confirm-or-fix step before anything is committed, backed by an internal automation platform we run on OpenAI and Claude. BD Automation: internal AI workflow platform, ask me for a walkthrough. On the architecture, keeping PostgreSQL as the only source of truth with logic in views, functions and triggers is the right call, but the ≥95% accuracy target depends heavily on your product alias normalisation. How clean is the alias data now, and do you already have the 100 real messages for the test set? That gap decides whether 7 days is realistic. Yes, I can work 7 consecutive days. I'd handle the backend and n8n, one teammate on Retool. First step: share the spec and the message sample. Adil

@ranjika08

Your specification is detailed enough to build from properly, which is a big plus for a project like this. I’m comfortable with PostgreSQL functions/views/triggers, migration-based schema control, Retool bulk-entry interfaces, self-hosted n8n workflows, and Telegram bot integrations with structured extraction. I can commit to the 7 consecutive working day timeline, and the work would be handled by me with support from one in-house developer where needed for speed and QA. If you want, I can share a Retool sample and outline the delivery plan here on the platform.

@DrSyafiq

You're building Build an internal trading desk platform — PostgreSQL + Retool + n8n + Telegram bot, where the real delivery risk is usually in the workflow details, not just the feature list. I've handled similar builds involving PHP, Software Architecture, Microsoft Access, PostgreSQL, usually where the important part was translating the brief into a reliable working system. My approach would be to first define the input schema, generation rules, and output validation, then build the workflow around those controls so AI output stays consistent. For this project, I would focus especially on: - Input workflow design, prompt/control rules, and output validation - Backend processing, file/document generation, and dashboard usability - Scalable cloud structure, API boundaries, and error handling If helpful, I can map the input-to-output workflow and where validation should sit before implementation. Best, Dr. Syafiq

With over a decade of industry experience, I am the perfect match for your internal pricing platform project. My specialization in PostgreSQL, which aligns directly with the required database management for this task, ensures I can create and implement an effective pricing structure using triggers, functions, views, and migrations. Having built numerous trading-related software applications in PHP, such as Laravel and CodeIgniter, I have gained an in-depth understanding of the domain, which will undoubtedly benefit your enterprise. Additionally, I have hands-on experience with Retool. Another area where I bring significant expertise is efficient data extraction through APIs like LLM, which seems crucial to your platform. As indicated in the project description, high accuracy rates are expected during extraction; I assure you that my methods have previously consistently surpassed the required 95% accuracy threshold even with complex documents. In wrapping up, you will find my work ethic dedicated and transparent throughout this project. As per your requirement of 7 consecutive working days with everything done in your name from start to finish - that aligns perfectly with how I usually operate. Your satisfaction is my utmost priority and finally, please find a sample Retool app I built here: (provide link) Thank you for considering me for your project. Let’s connect further to discuss details.

@mahig47

Hello! As per your project specification, you need an internal pricing platform with PostgreSQL as the single source of truth and Retool, n8n, and a Telegram bot working around it. The priority is not just getting the interfaces working, but following your defined architecture with migrations, database driven business logic, auditability, versioned pricing, and reliable LLM extraction. I can implement the PostgreSQL foundation with approximately 18 tables, versioned migrations, supplier offers, buyer requirements, price books, product alias normalization, margin rules, audit history, and price history using triggers. The Retool application can cover search, price entry, bulk entry, deals, approvals, and administration, while n8n can handle mailbox capture, Telegram webhooks, expiry workflows, and nightly digests. I specialize in PostgreSQL, Retool, n8n, Telegram Bot API, LLM integrations, workflow automation, database driven applications, and structured data extraction. I will follow the specification closely and keep the implementation modular and maintainable so future changes can be introduced through migrations and versioned workflows. Let’s connect to review the specification and confirm the database, Telegram, Retool, and n8n workflow dependencies so we can execute the seven day delivery plan efficiently. Best regards, Nikita Gupta.

@vladang

Seven-day delivery is realistic only with the PostgreSQL contract locked first. I’d make SQL views, functions, and triggers the business layer, then connect Retool, Telegram, and versioned n8n workflows without duplicating rules. Raw messages are stored before parsing; Confirm/Fix feedback becomes the test loop for reaching ≥95% accuracy across the 100-message set. Retool bulk actions will call transactional database functions, so partial imports cannot leave prices or approvals inconsistent. I’ll also keep migrations reversible and audit/history triggers separate from operational logic. 1. I don’t have a public Retool screenshot I can honestly share in this bid. My closest relevant B2B approvals/roles demo is craftline-portal.vercel.app. 2. Yes, I can work all 7 consecutive days. I’ll work on the project myself; no subcontractors. Repositories and accounts remain in your name from day one. Please share the specification and anonymized message set so I can flag any seven-day delivery risks before kickoff.

@naminghn

Hi there, I can confirm immediate availability to deliver your internal pricing platform within the required 7 working days. My experience with PostgreSQL, including complex triggers and migrations, combined with developing custom Telegram bots and utilizing Retool for application interfaces, aligns perfectly with your project needs. I am ready to work alongside any necessary team members, and I'm eager to collaborate on this efficient pricing system. Your satisfaction is my priority and I guarantee that I will deliver you a high-quality result. Regards, Ali

@kishanbwts

I’ve built PostgreSQL-based pricing platforms before where all business logic lived in SQL views and triggers, keeping the database as the single source of truth. Versioned migrations and foreign keys for data integrity are standard in my workflow. For the Telegram bot, I’d set up a standalone service that stores raw messages before parsing, then uses your LLM model to reach 95%+ accuracy on key price fields, with a quick Confirm/Fix/Discard loop. I’ve integrated n8n workflows for webhook handling and nightly digests in self-hosted setups, ensuring stable and versioned automation. Can you share the LLM model and format expected for the extracted data fields? Also, do you have existing Retool components to build on, or should I create everything from scratch? I can share screenshots of a Retool app I built for bulk data entry in a trading context. I am available for 7 consecutive working days and will handle all work personally. Ready to start immediately and deliver fully owned repos and accounts as you require.

@tnt42010

Hello, I’m an independent developer and can work 7 consecutive days on this project. No other developer would be involved unless you explicitly request it. Your architecture is clear: PostgreSQL as the sole source of truth, with business logic in SQL views/functions/triggers, versioned migrations, raw-message retention before parsing, and a standalone tested Telegram service. I have strong experience with: PostgreSQL triggers, functions, views, migrations, audit/history design n8n workflows and webhooks Telegram Bot API LLM structured extraction with validation/testing Retool-style internal tools and bulk-entry workflows API/backend integration and production deployment I can build to the provided specification, keep all repos/accounts under your ownership from day one, and work fixed-price. I’d first review the schema, Retool screen spec, and the 100-message LLM test set, then execute strictly against the 7-day delivery plan.

@waqaswebmaster

I can deliver this as a production-ready internal trading desk within the required 7 consecutive working days. I’m strong with PostgreSQL architecture, migrations, triggers, functions, views, audit history and keeping the database as the single source of truth. I can build the Retool workflows and bulk-entry experience, standalone Telegram bot, structured LLM extraction with validation against the required real-message test set, and self-hosted n8n workflows with proper versioning and error handling. I’ll keep all repositories, credentials and project assets under your ownership from day one, with the implementation organized for reliable maintenance and extension. I can work the full 7-day schedule and handle the development directly. Waqas Ahmed

@shayankhan333

Storing raw inbound Telegram messages before parsing is the right call, it's what lets you re-run extraction when the LLM prompt improves without losing history. I'll ship the Postgres schema with versioned migrations (sqitch or Flyway), triggers for audit and price history, SQL views for margin logic, a standalone Telegram bot service with pytest coverage on the extractor, Retool screens including a bulk-entry grid, and self-hosted n8n flows for mailbox, webhook, expiry and digest. One catch worth flagging: hitting ≥95% on free-text prices usually needs a product alias seed list before the LLM sees a single message, otherwise accuracy stalls around 80. Solo, working the 7 consecutive days, repos and accounts in your name from day one. I'll share Retool screenshots in chat. Best regards, Shayan

@mayr81

Hello, I've built exactly this kind of Postgres-first internal tooling before: a supplier/buyer price book where every rule lived in SQL views, functions and triggers, with versioned migrations so nothing was ever changed by hand in the database. On the Retool side, I've delivered a procurement app with searchable offer grids, a bulk-entry sheet that validated rows against product and grade foreign keys before commit, plus approval queues and an admin panel — I'm happy to screen-share a live walkthrough of that app since the client owns the workspace and I can't post screenshots publicly. For the Telegram bot I'd keep it a standalone service with its own test suite, storing the raw inbound message first, then running LLM extraction into a structured payload and returning Confirm / Fix / Discard inline buttons that write only on confirm. Product alias normalisation would sit in a lookup table with a matching function so unknown aliases surface for admin review instead of silently failing. n8n (self-hosted, workflows exported to the repo for versioning) would handle mailbox capture, the Telegram webhook, offer expiry and the nightly digest. Accuracy work would be a scripted harness over your 100 real messages, reporting per-field precision so we can tune prompts until key fields clear 95%. Best regards!

@melopgabriel

Hi, this is a tightly defined internal trading desk build, and the key work is turning your specification into a reliable PostgreSQL-first system with clean approvals, price history, and fast entry flows. I’ve built internal tools with PostgreSQL-backed business logic, trigger-based audit trails, and Retool interfaces for search, bulk entry, and operational workflows. I’m also comfortable wiring Telegram Bot API flows and n8n automations with raw message storage and structured parsing. My approach would be to implement the schema and migrations first, then the SQL views, functions, and triggers, followed by the Telegram bot, Retool app, and n8n workflows. I’d test the extraction flow against real messages and keep all code, repos, and accounts in your name from day one. I can work the full 7 consecutive days, and I’ll be the only developer on the project. If helpful, I can share relevant Retool examples and discuss the delivery plan. Best regards, Gabriel

@longngoc2307

==== Hi - Truong here ==== "INTERNAL TRADING DESK PLATFORM" — you need PostgreSQL to remain the single source of truth while Retool, n8n and Telegram work around it reliably. I’d put the business rules in PostgreSQL functions, views and triggers, with migrations for every schema change and raw Telegram/mail messages stored before LLM parsing. For the Telegram flow, I’d use structured extraction with Confirm/Fix/Discard and test it against the 100 real messages rather than assuming 95% accuracy. Can you share the technical specification and confirm whether I would be the sole developer for the full 7-day delivery? Looking forward to working with you.
