I’m days away from launching my Instamart-style delivery app in India Locally to Andhra Pradesh built with Flutter (mobile) and PHP (backend). The core platform is ready; however, I now need a compact ERP layer added before we hit the stores. The original vendor’s quote for this last piece is excessive, so I’m looking for a seasoned developer who can step in, study the existing codebase, and finish the job and particularly around Andhra, Tamilnadu or Karnataka neighbourhood Scope of the module The ERP addition is focused on two areas only: • Order tracking – real-time status updates from pick-up through delivery, visible to both users and our dispatch panel. • Customer management – a lightweight CRM view to see purchase history, contact info, ...

Core scope • PHP website that lets visitors browse a structured product catalog. • Admin Panel to create, edit, and organise products, media, and users, secured with role-based access. • RESTful API powering both the site and the Flutter apps, produced in well-documented, neatly organised code. • Flutter apps mirroring the website’s catalog experience and consuming the same API for perfect data parity.

My Replit project needs a WhatsApp integration that can both send and receive messages in real time. I work exclusively in Python on Replit, so the entire solution must run within that environment without relying on locally installed services. What the finished module should handle for me: • Message templates so I can reuse common replies and broadcast texts. • File attachments (images, PDFs, etc.) sent and received, with the files saved to Replit storage or an S3-style bucket I can configure. • Message scheduling that lets me queue outbound messages for future delivery, preferably via a simple cron-style or timestamp trigger. I’ll need setup with meta api and setting up business api account with templates once the basic scaffolding is in place. Clean, well-comme...

I’m building a new website and now need the database layer put in place. The only backend responsibility for this first phase is clean, efficient database interaction—no user-auth flows or external API bridges yet. The stack choice is settled on MySQL, so I need you to design the schema, implement well-structured queries (or stored procedures if they make more sense), and expose everything through a lightweight service layer that the front-end can call. You’re free to pick the server-side language and framework you’re fastest with—PHP (Laravel / Symfony), Node.js (Express, Fastify), or Python (Flask, Django) are all fine—as long as the final code is readable, documented, and easy to extend. Please include: • an ER diagram and migration scripts &...

I’m rolling out a full-fledged hotel booking ecosystem that lives on three fronts: a customer-facing Android app, an iOS app, and a browser-based admin portal. The apps must let travellers search live inventory, choose an exact room (e.g., “Room 457” instead of a generic “Double”), pay securely, and leave ratings and reviews once their stay is over. Property data can never be stale, so real-time room availability has to stay in sync with external channels such as Airbnb and ; whichever API or iCal approach you prefer is fine as long as double-booking risk is zero. Each hotel owner will have an individual account with the freedom to update rates, photos, descriptions, blackout dates, and promotions at any moment without touching code. Multi-layer user per...

I need a bespoke payment gateway built and fully verified for the Ghanaian and Nigerian markets. It must natively process mobile money, direct bank transfers, and debit / credit card payments without routing funds through foreign intermediaries. During user onboarding I want a KYC-driven verification flow—government-issued ID capture, selfie match and real-time checks against local watchlists—so the service launches already compliant with regional regulations. You will handle the entire build: API design, merchant dashboard, customer checkout screens, sandbox and live environments, plus submission to every required bank, network or regulator until the gateway is officially approved for production use. Once live, I expect: • Production-ready REST / Webhook APIs with samp...
