What I'm looking for

I seek a mid-level full-stack role building scalable web products with real-time features, strong engineering practices, and opportunities to improve performance and deploy production systems.

I am a Full-Stack Developer experienced in building scalable, production-grade web applications using the MERN stack and Vue, with a focus on clean code, performance and system design.

I have delivered 10+ client projects and multiple live products, integrating features like payment gateways, real-time Socket.IO communications, OpenAI automation, and complex MongoDB aggregation pipelines to improve speed and reliability.

I collaborate well in Agile teams, optimize systems (reducing load times and improving throughput), and deploy applications using Linux/Nginx with a priority on maintainability and measurable impact.
