What I'm looking for

I seek a collaborative, growth-oriented engineering role where I can build scalable full-stack systems, apply DSA, increase test coverage, and work with cloud/AI technologies.

I am a full-stack software developer with hands-on experience building and testing modern web applications using Java, Node.js, and React.js. I have improved application performance by 50%+, achieved 90%+ test coverage in backend components, and delivered end-to-end features for SaaS, OCR, and browser-extension projects.

I excel at applying data structures and algorithms to solve engineering problems—accelerating simulations and reducing execution time—as well as designing modular system architecture and clear documentation. I am a quick learner who thrives in Agile environments and is eager to contribute to hybrid cloud and AI-focused teams.
