I need an experienced developer who feels at home in both TypeScript and Python and has already played with the popular open-source “AI agent” stacks. My immediate goal is to stand up a proof-of-concept chatbot that can reason over structured data stored in a SQL database, surface answers in natural language, and be easy for me to extend later. Here is what I’m after: • Pick and wire up an open-source autonomous-agent framework (LangChain, AgentGPT, SuperAGI or a comparable option you trust). • Expose a clean TypeScript interface so the rest of my app can call the agent with a prompt and receive a streamed response. • In Python, configure the agent’s toolset to pull data from my existing Postgres tables, run simple analytic queries, and return concise answers. • Ship working code, a short README, and a one-click launch script (Docker or npm) so I can reproduce the demo on my own machine. Acceptance will be based on: 1. Chatbot reliably answering basic “what/why/how many” questions by hitting the database, not hallucination. 2. Code quality—clear project structure and docstrings/comments where decisions matter. 3. A quick hand-off call or Loom video walking me through setup and how to add new tools or skills. I’m on a tight timeline, so if you’ve done something similar before and can jump in right away, I’d love to see it.

I am Sumit Joshi from Sacesta Technologies. Recommended approach • Agent framework: LangChain (mature ecosystem) with a strict SQL tool and guardrails • Python service: agent + tools + query validation, streaming output • TypeScript interface: lightweight client SDK that sends prompt plus context and receives streamed tokens • Safety: enforce read-only SQL, schema awareness, and result-grounded answers Core build • Postgres toolset: schema introspection, safe query builder, and basic analytics queries • Agent policy: always cite rows or aggregates returned, refuse if data not found • Streaming: SSE or WebSocket from Python, consumed by TypeScript SDK • Project structure: clear modules for tools, prompts, policies, and adapters • Dockerized launch: one command to run Postgres connection + agent service + TS demo client Deliverables • Working repo with Python agent service and TypeScript SDK • README with setup, env vars, and examples • One-click launch via Docker Compose or npm scripts • Short walkthrough video covering how to add new tools and skills Relevant experience • RAG and tool-using assistants with Postgres and structured querying • TypeScript + Python systems with streaming APIs and clean handoff docs Key questions • Do you want the agent to answer only from a fixed schema, or support dynamic table discovery • Any PII tables that should be blocked by policy Regards, Sumit Joshi

Hello, I’m excited about the opportunity to contribute to your project. With strong experience in TypeScript + Python and practical hands-on work with open-source agent stacks, I can deliver a clean proof-of-concept chatbot that answers “what/why/how many” questions by reliably querying your Postgres tables, streaming responses back through a TypeScript interface, and staying easy to extend with new tools later. I’ll tailor the build around a proven agent framework, wiring a Python toolset for safe, schema-aware SQL access and simple analytics while keeping hallucinations in check, then exposing a straightforward TS API for your app plus Docker/npm one-click startup and a concise README. You can expect clear communication, fast turnaround, and production-minded code quality with a quick walkthrough showing exactly how to run it and add new capabilities. Best regards, Juan

Dear Client, Greetings!! I have gone through the project description, and found that all of the mentioned requirements fall over my expertise, as I have hands-on experience on python, typescript, AI/ML, Data Science, software building, etc. I have hands on experience building agent based chatbots with Python and TypeScript using LangChain style tool calling over SQL databases. I would set this up as a clean proof of concept where the agent answers questions by querying Postgres directly, exposed through a simple TypeScript interface with streamed responses. The focus would be correctness first no hallucination, then clean structure so you can extend tools later. I can ship this with Docker, a clear README, and walk you through how everything fits together. Lets discuss further over a chat. Also, I have been coding on Machine Learning and Data Science with python from past 7 years. I have the experience of working with 4 giant tech companies, including freelancing on upwork, fiverr and freelancer. Hope to hear from you soon!!. Regards, Rojan

I have built similar agents using LangChain's SQL toolkit to query Postgres databases directly from natural language. For this POC, I will set up the Python agent to read your schema and generate valid SQL, ensuring it sticks to the actual table definitions to minimize hallucinations. I will wrap this in a clean TypeScript API and package it all in Docker for a one-click launch on your machine. How complex is the Postgres schema you want to test—are we talking about 5-10 core tables, or a massive dataset?

Hi there. This POC will land if the agent is forced to query Postgres as the source of truth, streams responses cleanly to TypeScript, and stays easy to extend with new tools. Pitfalls are hallucinated answers, unsafe SQL generation, slow queries or locks, schema drift breaking prompts, and messy glue code between TS and Python. First I will inspect your Postgres schema and sample questions, then wire LangChain with a strict SQL tool plus allowlisted tables, and stand up a TS streaming gateway that calls the Python agent and returns tokens to your app. Do you want the agent to write raw SQL only, or can it call curated views and stored functions for analytics? Should the response include the SQL it ran and row counts for audit, or only the final answer? I have built RAG and tool based agents that answer what why how many questions by executing SQL with guardrails and returning verifiable outputs. I can start immediately, share a runnable Docker demo quickly, and include a short recorded walkthrough and README for adding new tools. Danylo Podolskyi
