About & Philosophy

Architecting for scale, security & user impact

Passionate about building fast, accessible, and resilient web applications that solve real business problems.

A problem-solver focused on product excellence

I am a results-driven Full Stack Developer based in Bengaluru with over four years of hands-on experience owning complex web software across the full development lifecycle — from microservice API design and schema modeling to accessible, pixel-perfect frontend applications.

On the frontend, my core strength lies in React, Next.js (App Router, SSR/SSG/ISR), TypeScript, and modern component design systems. On the backend, I design reliable RESTful APIs, real-time WebSockets, auth flows (OAuth 2.0, WebAuthn, JWT), and database schemas with Node.js, Express.js, MongoDB, and MySQL.

I focus heavily on Web Performance & Core Web Vitals (LCP, FID, CLS), automated test pipelines (Jest, React Testing Library, Vitest), and scalable architecture that delivers real business impact.
