I already have the full mobile-first UI finished; what is missing is a production-ready backend that lets the app feel alive. The core of the job is building a points engine that rewards users both for in-app activity and for purchases they make through our marketplace flow. Actions such as posting, reacting, completing challenges, or finalising a purchase should trigger configurable rules that add or deduct points, write an auditable record, and update the user’s running balance in real time. All sign-ups and log-ins will flow through social media OAuth, so I will need solid integration with the common providers and a clean way to attach those identities to our internal user table. The database schema, migrations, and any caching strategy are part of the scope; I am not tied to a specific stack, but the solution must scale beyond a proof of concept and expose clean REST or GraphQL endpoints that my React-Native front-end can consume. Please lean on your past experience designing secure token-based auth, transactional point ledgers, and purchase webhooks when you respond. I will look mainly at similar projects you have shipped, your approach to data integrity, and how you plan to stage the work from local dev through cloud deployment. Key deliverables • Database design and migrations • Modular points engine (activity + purchase triggers) • Social login flow with token refresh & revocation • Fully documented API endpoints ready for front-end consumption • Deployment scripts or IaC for staging and production environments I will be available for UI walkthroughs and test cases, and I am happy to iterate quickly on Slack or GitHub as needed. Looking forward to seeing how you would tackle this.

Hi! I'm a Software Engineer with a focus on high-performance backend architectures. I've designed transactional ledger systems and integrated social OAuth for production-grade apps before. My Technical Approach for your Backend: 1. Production-Ready Database: I'll design a PostgreSQL schema with an auditable "Points Ledger" to ensure data integrity for every transaction (add/deduct). 2. Social Auth: I'll implement a robust OAuth flow (Google/Apple) with secure JWT handling, token refreshes, and revocation logic. 3. Modular Points Engine: I’ll build a trigger-based engine where activity and purchase webhooks (marketplace flow) update user balances in real-time. 4. Scalability: The API will be fully documented (Swagger or GraphQL) and containerized for seamless scaling on cloud providers. I’m ready to deliver a clean, documented, and auditable backend that scales with your growth!

I saw your project and am confident I can deliver on this. I'm currently working on a similar project and understand the importance of a robust backend for a social app. Building a points engine that rewards users for various activities and purchases is key. By ensuring seamless integration with social media OAuth and designing secure token-based authentication, I can create a dynamic backend that enhances user engagement and experience. With a focus on data integrity and scalable solutions, I guarantee a production-ready backend that aligns with your vision for the app. I invite you to view my portfolio, which showcases the quality and results of my past work. I look forward to hearing from you. Regards, Sadiya

Backend API work is what I do every day — I build the services that sit behind mobile apps and make them feel alive. This is a natural fit. For the points engine, I'd model it as an event-driven system. Every qualifying action (post, react, challenge completion, purchase) emits an event that the points service picks up, validates against your rules, and credits to the user's balance. This keeps the logic clean and makes it easy to add new reward triggers later without touching existing code. The rules engine itself would be config-driven so you can tweak point values, multipliers, and thresholds without a code deploy. On the API side, I'll build it with both REST and GraphQL endpoints depending on what your mobile app expects. OAuth 2.0 for auth, with proper token refresh and role-based access so you can distinguish between regular users, merchants, and admins. All endpoints documented so your frontend team can work independently. For the database, I'd go with PostgreSQL — solid for both transactional data (points, purchases, user profiles) and the kind of aggregation queries you'll need for leaderboards and activity feeds. Clean schema design with proper indexes so it stays fast as your user base grows. I'll include logging and basic observability from day one — you'll be able to see points earned, redeemed, and the events that triggered them. Makes debugging straightforward and gives you data for product decisions later. Delivered with full source code, API documentation, database migration scripts, and a Docker setup for easy deployment. Happy to walk through the architecture on a call before I start building.

Hello, I can build a production-ready backend that powers your mobile app and delivers a scalable points reward engine for both user activity and marketplace purchases. My approach is to design a modular points ledger system where every action (posting, reactions, challenges, purchases) triggers configurable rules. Each transaction writes to an auditable points ledger, updates the user balance in real time, and ensures data integrity through atomic database transactions. This structure keeps the system transparent, reversible, and easy to extend. For the stack, I recommend Node.js (NestJS) or Laravel API + PostgreSQL + Redis caching, exposing clean REST or GraphQL endpoints for your React Native app. Social authentication will support OAuth providers (Google, Apple, Facebook, etc.), with secure JWT token management, refresh tokens, and revocation logic tied to your internal user model. Key deliverables: • Database architecture & migrations • Configurable points engine (activity + purchase triggers) • Secure OAuth login with token lifecycle management • Documented REST/GraphQL APIs for front-end integration • Deployment pipeline for staging & production (Docker + cloud scripts) I focus heavily on transaction safety, webhook validation for purchases, and scalable architecture so the system grows beyond MVP. Happy to collaborate via Slack/GitHub, review UI flows, and iterate quickly toward launch.

I read your requirement for the social app backend and understand you need a production-ready points engine with social OAuth and secure, scalable APIs. I have recently completed a similar project — the mBART50 Translation API, a scalable backend supporting multiple engines with clean API design. My skills in Node.js/Express.js, REST APIs, PostgreSQL, and my AWS Certified Machine Learning – Specialty certification ensure a robust build. I can structure this in two milestones. Are you available for a quick chat to discuss the details?

This isn’t just a backend build it’s a real-time system where data consistency, scalability, and user engagement must work flawlessly together. That’s exactly what I specialize in. I’ll build a production-ready backend with a robust points engine and secure authentication designed to handle real users and real transactions without breaking. Your requirements map directly to systems I’ve built: ✔ Modular points engine (activity + purchase triggers) ✔ Transactional, auditable ledger (no inconsistencies) ✔ Real-time balance updates with concurrency handling ✔ Secure OAuth with token lifecycle management ✔ Clean REST/GraphQL APIs for React Native The points engine will be event-driven and extensible, so future rules won’t require core changes. Quick clarification do you want reward rules configurable (admin-based) or fixed initially? On the architecture side: - Scalable DB schema + migrations - Strong data integrity (atomic + idempotent ops) - Smart caching without risking consistency - Reliable purchase webhooks I focus on security, performance, and long-term maintainability, not just delivery. Delivery plan: 1. Schema + OAuth 2. Points engine 3. API + docs 4. Deployment (staging → production) You’ll get a backend that’s stable, scalable, and built to grow. Let’s connect and get this moving.
