I’m a Software Engineer with 4 years of experience in full-stack development, specializing in building scalable, production-grade applications using modern JavaScript technologies—especially the MERN stack. I care deeply about performance, scalability, and maintainable architecture, and I enjoy system design for real-time and AI-powered solutions.

At Bacancy Technology, I enhanced geospatial data visualization by fixing map pin overlay issues using a butterfly clustering approach, improving clarity and interaction across large datasets. I refactored my frontend into modular Next.js components, collaborated cross-functionally, and improved code quality with unit testing (Vitest, React Testing Library) to reach 90% test coverage. I also contributed to a microservices-based architecture using RabbitMQ for asynchronous communication.

At FOG Technologies, I architected an interactive LED floor gaming platform with the MERN stack, Electron.js, TypeScript, and Realm DB—supporting dynamic gameplay and real-time interactions across international venues. I managed a team of 5–7 developers through sprint planning, prioritization, code reviews, mentoring, and unblock leadership to ensure timely releases. I optimized performance by redesigning IPC communication and externalizing static assets, reducing bundle size and build time by 50%, and implemented AWS S3 and Lambda-based OTA update workflows.

Earlier at Codelink Infotech, I engineered scalable full-stack applications using the MERN stack and delivered reusable APIs and modular, maintainable architectures across production projects. I integrated TradingView APIs and GraphQL for fintech platforms and supported deployment on Hostinger and DigitalOcean. I also build AI-focused systems like InsightAI (a production-grade RAG system with LangChain and vector search) and Nova Mart (an AI-assisted e-commerce platform), always focused on practical, end-to-end delivery.
