You will get a Secure and Reliable Backend That Just Works
Project details
If your backend is slow, insecure, or poorly structured, everything else suffers. This service builds Node.js backends that are clean, secure, and easy to scale. APIs are designed with clear logic, proper validation, and efficient database queries using SQL or NoSQL. Whether you need authentication, data management, or third-party integrations, everything is built to support real users and real traffic. You get a backend you can rely on, not something that needs constant fixing.

I am a Senior Full-Stack Engineer specializing in integrating AI into real-world workflows, crafting premium user interfaces in Next.js, and scaling high-performance React Native mobile applications from 0 to 1.
My focus is on Product-Minded Engineering: ensuring the frontend, backend, and APIs work seamlessly together to solve actual business problems without crashing under load.
My Production Impact:
📈 Performance at Scale: Optimized ledger and payment flows for 100K+ active B2B users on Udhaar Book. Cut app startup time by 40% through deep Hermes engine tuning and FlatList virtualization.
🛡️ Enterprise Reliability: Maintained zero production rollbacks across 6+ consecutive monthly sprints on Lumida Wealth, a high-net-worth Fintech platform.
⚡ Backend Optimization: Slashed API latency by 50% and reduced mobile crash rates from 5% to 2% for Dastgyr, processing 10,000+ daily orders with zero infrastructure increases.
🤖 AI Integration: Engineered an AI-powered Visa Advisor leveraging OpenAI APIs and RAG pipelines to cross-reference 17 government sources into a real-time scoring engine.
The Complete Technical Stack I Bring to Your Project:
While my expertise lies in React Native and AI, I handle the entire engineering lifecycle:
• Mobile Apps (iOS & Android): React Native, Expo, Hermes, Crashlytics, Flipper, Mobile Performance Tuning.
