My product roadmap calls for a series of new Python-based RESTful endpoints and some refactoring of the existing backend. I want one experienced individual—no agencies or team hand-offs—to take ownership of this slice of work from design through deployment. The core of the assignment is building and documenting clean, well-tested RESTful routes that slot smoothly into the current codebase. Everything should follow best practices for security, pagination, error handling, and versioning so the API is easy to maintain and simple for front-end consumers to use. I am flexible on framework choice (FastAPI, Flask, Django REST Framework, or similar) as long as you can justify it and deliver production-ready code. You will: • Analyse the current architecture and propose an endpo...
Overview We are extending an existing GoHighLevel (GHL) Affiliate onboarding and referral system to support a mobile app built via AppMySite. The app will authenticate users against WordPress, then display a universal campaign library (campaign URLs, funnels, websites, etc.).

This brief is intentionally concise; developers are expected to propose and validate the best technical approach and confirm feasibility. Current State (Already Built) - A form currently creates: - - An Affiliate in a GHL sub-account - - A corresponding User (admin) in GHL - Referrals are already being connected/attributed inside GHL Requirements 1) GHL User → WordPress Use...

I’m building an accounting platform aimed squarely at professional accountants and I need someone who can wear the CTO hat from day one. Your first mission is to shape the entire back-end architecture and then guide (or code) the initial release.

I’m expanding my product with real-time voice and video calls and now need a seamless way to land users directly on the profile page by scanning a QR code. The same code must behave consistently across iOS, Android, and the web. Here’s the flow I’m after: • A unique QR code is generated for each user. • When scanned, it opens the app (or relevant web view) straight to that user’s profile page—never a generic landing screen. • From the profile page the standard call buttons already present will handle voice or video, so no auto-dial on scan is required, only reliable deep-linking.

I’m building a Shopify store that sells made-to-measure curtains. Every order’s price must be calculated from the shopper’s width and height inputs, then carried all the way through to checkout without relying on any front-end trickery or draft-order workarounds. In other words, the figure a customer sees on the product page has to be the exact figure that lands in the cart and is enforced at payment. What I need: • A clean, production-ready implementation—theme code, a bespoke Shopify app, or a hybrid approach—that watches the two dimension fields, runs the formula I’ll supply (price per square metre plus optional extras), and injects the true line-item price. • Complete preservation of Shopify’s native discounting, taxes, and shippi...

I have a fully working single-page ERP/POS application (NexusERP v2) that currently runs 100 % on the browser and stores everything in localStorage. The front-end code is clean ES6 modules with modern CSS, so your focus will be the server side: designing and wiring up a real database layer. My only requirement right now is database integration.

I’m kicking off a new-product R&D cycle and need an engineer who loves turning blank-sheet ideas into working software. The entire effort is green-field: no legacy code, no fixed stack—just a clear mandate to research, prototype, and validate a fresh concept before we move to full-scale development. You’ll start by exploring technical approaches, comparing frameworks, and mapping out architecture options that balance performance, scalability, and cost. From there, I expect rapid proof-of-concept builds to stress-test core features and expose unknowns early. Your findings—both successes and dead ends—should be documented clearly so we can make informed go/no-go decisions at each stage. Deliverables I need to see: • A concise research brief outlining ...
