What I'm looking for

I’m looking for a team where I can own architecture end-to-end—shipping production mobile, backend, and web features in Agile/Scrum, building real-time systems and scalable pipelines that turn requirements into measurable product impact.

I’m a Software Engineer with 3+ years of experience delivering complete, production-grade platforms across mobile, backend, and web. I love translating complex business requirements into scalable, deployable systems—owning architecture, APIs, data pipelines, and mobile applications end-to-end.

My core expertise is Flutter for cross-platform mobile, plus NestJS/Node.js for backend microservices. I’ve built real-time, event-driven systems with Kafka, WebSockets (Socket.io), and MongoDB Change Streams, and implemented secure API layers using OAuth 2.0 and JWT.

I’ve also delivered subscription and billing infrastructure across multiple gateways—Stripe, Razorpay, and PayPal—covering webhook processing, plan lifecycle (upgrades/downgrades), credit allocation, usage limits, and automated schedulers. On the data side, I’ve engineered Apache NiFi ETL pipelines for multi-source RSS ingestion and transformation at scale.

Most recently, I’ve been building scalable Flutter applications with Clean Architecture patterns (BLoC), responsive UI, and analytics instrumentation using Firebase Analytics and MoEngage. I bring strong Agile/Scrum collaboration habits—sprint planning, code reviews, and shipping reliably with cross-functional teams.
