You will get a secure Node.js backend with clean APIs and PostgreSQL DB
Project details
I will develop a secure, scalable Node.js backend with clean API architecture and a fully optimized PostgreSQL database. From authentication to advanced business logic, I deliver production-ready APIs with proper validation, error handling, caching, and documentation. Whether you need a simple CRUD service or a complete backend for a mobile/web app, you will get a reliable, fast, and well-structured system built to scale.

Frequently asked questions
About Ritik
Full Stack & Mobile Engineer | React Native, Node.js, Real-Time System
Greater Noida, India - 3:33 pm local time
APIs and database, to a live deployment on AWS. My core stack is React Native and Node.js,
and I specialize in real-time features that are genuinely hard to get right: chat, live
location tracking, notifications, and payments.
At my current role, I maintain a fault-tolerant chat server handling thousands of
concurrent WebSocket connections, and reduced message delivery latency by ~30% (sub-150ms
delivery) — the kind of performance work that matters when users are relying on your app
in real time. I've also shipped backend services for a production platform, focusing on
API reliability, validation, and reducing failure points across services.
Beyond client work, I've built several products from scratch, including:
- An enterprise-grade, multi-tenant HRMS platform (under NDA) that any business can
onboard onto, plug in their own company data, and use immediately — covering live
location–based attendance, push notifications, project management, employee training,
and payroll
- An enterprise-grade measurement management app (under NDA) for tailoring businesses,
supporting both individual and bulk customer measurement capture and management
- An EdTech platform with daily practice tests, mock exams, and an integrated AI assistant
for exam/career queries
I also hold a published patent for an AI-based emergency response system and co-authored
an IEEE paper on AI in emergency care — so I bring a genuine problem-solving, systems-level
mindset, not just implementation.
What I can help you with:
✓ React Native apps (iOS & Android) — from MVP to Play Store/App Store launch
✓ Node.js/Express backend APIs — REST, JWT auth, WebSockets, validation, error handling
✓ Real-time features — chat, live tracking, push notifications, live updates
✓ Database design & optimization — PostgreSQL/MySQL, Redis caching, indexing
✓ AWS deployment — EC2, RDS, CI/CD, Nginx, environment configuration
✓ Full ownership — I'm comfortable owning a feature from UI to database to deploy, or
slotting into your existing team and codebase
I communicate clearly, give realistic timelines, and flag risks early rather than after
they become problems. If you need someone who can move fast on an MVP or stabilize and
scale an existing product, let's talk about what you're building.
