What I'm looking for

I seek a mid-level engineering role where I can build scalable web applications, improve UX, work with modern React/Node stacks, and grow toward technical leadership in a collaborative team.

I am a full-stack software engineer with over three years of hands-on experience building responsive, scalable web applications and improving product usability.

At Flexi Ventures I developed end-to-end features for a DeFi web app serving 50,000 users and created UI components that increased customer satisfaction by 40% through improved navigation and design.

Previously at InTime Tec I worked as a Full Stack Developer on React.js/Redux frontends and Node.js/Express backends, deployed on AWS, implemented complex datagrids and hierarchical data structures, and resolved 80% of critical bugs via debugging and unit testing.

I focus on delivering quality solutions, embrace continuous learning, and bring a track record of hackathon wins and production-ready projects including complaint and canteen management systems.
