About Me

I'm a versatile full-stack software engineer with over 4 years of hands-on experience designing and shipping production-grade web applications. At ARITS Limited, I've progressed from intern to Software Engineer — leading the frontend architecture of complex products including HumR (an in-house multi-company HR platform), a UK rental platform, and various client-facing websites.

I thrive at the intersection of clean code and great user experience — from architecting secure SSO systems with cookie encryption to integrating payment gateways and building dynamic form builders. I'm passionate about developer tooling, performance optimisation, and technical SEO.
