I am putting together a REST-style API built with PHP and a MySQL database. Its first job is to return user information quickly and in clean JSON, so the user endpoints should focus on efficient, well-indexed SELECT queries and clear response structures. Alongside those read-only calls, I also need a second group of endpoints for product details that can: • return existing records (GET) • add or modify items (POST / PUT) • remove items (DELETE) You are free to work with native PHP, Slim, Lumen, or a full Laravel setup—whichever will let you keep the codebase modular and easy to extend.

I’m building out a new React front-end and now need the server side to catch up. The priority is a robust Node.js backend that exposes well-structured RESTful endpoints returning clean, predictable JSON. The data layer will live in MySQL, so you’ll design the schema, set up migrations, and write queries or use an ORM—whichever keeps performance high and code readable. Although Laravel experience is welcome and I do plan to introduce a small GraphQL layer later, right now your main focus will be the REST API: authentication (token-based), role management, pagination, filtering, and solid error handling. Clear inline documentation and a concise README or Swagger / OpenAPI file should accompany each route so the React team can plug in immediately. I’m flexible on tim...

• Description The objective is to create a prototype that sends our XML string via AS4 to a destination URL. You can start with <test>dummy</test> for now, but we will test with real xml. You will need to sign with the internal private key certificate and encrypt with the external public key certificate. The other side will decrypt with their private key certificate and verify our signature with our public key certificate. We will give you the certificates. You will then listen to our URL. They will send an async message 10-15 minutes later. We will give you access to our VPS, so the DNS will be routed to the VPS. You will need to verify their signature with their public key and decrypt the message with our private key. Success metrics are that the message is successfull...
I need a compact service that listens for every new Google Business review I receive and immediately posts a professional-sounding reply.

I want to keep a library of templates, edit them on the fly and insert customer-specific details such as their name, star rating or product mentioned. You are free to code in Python, Node.js or any language that works cleanly with the Google Business Profile API. A lightweight dashboard or a simple JSON/YAML file I can update...
I have the core pages of an online service–providing site sketched out, but everything still runs manually in the background. I now need the entire flow rebuilt so that it operates 100 % automatically through well-structured API calls. Here is what I expect once the job is done: • Users should be able to register, verify their email or phone, and manage their own profiles without my intervention. • A secure payment gateway must be integrated so that services can be purchased, renewed and, when required, refunded automatically. • Any service logic that currently depends on me pressing a button (for example activating a user’s subscription or sending a service result) has to be triggered through the API layer instead. You are free to choose the stack, prov...

Within my AppPresser-based mobile app I already expose BuddyPress settings, and the account-deletion button is visible to logged-in users. When it is tapped, however, the request consistently times out instead of completing the BuddyPress “Delete Account” routine on the connected WordPress site. Here is the current situation • AppPresser + BuddyPress (latest stable releases) power both the app and the site. • The button calls the built-in BuddyPress delete URL, but the process never finishes; the app shows a timeout page. • I haven’t yet pulled detailed server or device logs, so the exact error stack is still unknown. What I need from you 1. Diagnose why the request from the app is stalling—whether that is a REST/nonce issue, a CORS or SSL...
I am building an AI-driven workflow that takes products from Amazon and publishes them on eBay automatically. The core of the job is a Chrome-based extension tool that behaves like a real seller listing a real item while staying invisible to the marketplaces’ anti-bot systems.

Hi Freaks and Nerds, I'm looking to start a new Project together with an enthusiastic tech-freak on a couple of new ideas. Overall the thought can be described with building a new tech-platform, upon which less-tech affine people can build their own forms and process-automations with various automation-endpoints and AI integrations. Basically a modern predecessor for the ex MS InfoPath, but more innovative and flexible than MS PowerApps. I myself would start utilizing the very same platform to prepare use-cases and templates to go-to-market. Such as an ERP like system, field-service, productivity solutions for niche-markets. Following a few characteristics of how I would envision such a platform: UI: In my opinion, the UI should not require any installation of a client/software....
