What I'm looking for

I’m looking for a role where I can own full-stack delivery—web + mobile—using clean architecture, scalable APIs, and real-time systems. I want to ship production features end-to-end in Agile teams, with room to build AI-enabled products.

I’m a Full Stack Developer with 2+ years of experience shipping production-grade web and mobile applications across the complete stack. I build React.js frontends, Node.js and Python/Flask APIs, PostgreSQL/MongoDB data layers, and Flutter mobile apps with clean architecture and scalable design.

I’ve delivered real-world products end-to-end, including an AI-powered legal platform (Law-Mate) with a RAG chatbot, a labor marketplace (MehnatKash) with real-time matching and WebRTC video calls, and a client e-commerce platform (6am Mart). I’m experienced in REST API design, WebSocket systems, Stripe payments, Firebase, AWS, and Agile delivery—backed by 7 production-level projects and measurable improvements like reducing data fetch latency by ~30% and cutting a bug backlog by 40%.

I enjoy solving performance, integration, and reliability challenges—implementing secure JWT auth flows, third-party integrations, comprehensive error handling with retry logic, and modular backend services. I’m also hands-on with AI/ML features and developer-focused tooling, like a session replay & crash reporter SDK with real-time Firestore dashboards.
