Building scalable web applications and diving deep into auth, identity, and backend systems | MERN/PERN Stack | React Native

πŸ‘¨β€πŸ’» About Me

I'm a Full-stack engineer and co-founder of SpaceBuilder with a strong focus on the Node.js ecosystem and a habit of going deep on how things actually work - not just how to use them. That's led me to build everything from a from-scratch OpenID Connect Identity Provider to a client-side router to offline-first mobile tools. I care about understanding the protocols, the primitives, and the tradeoffs.

  • 🏒 Previously Jr Software Engineer β†’ Software Development Team Lead at Smartscripts Pvt. Ltd. (Mar 2024 – Mar 2026), owning the IT department, architecture decisions, and mentoring junior developers
  • πŸ” Built OIDC: Identity Provider + Next.js SDK (Live Demo) - A from-scratch OpenID Connect IdP with PKCE, RSA JWT signing, refresh token rotation, and JWKS discovery (my deepest work yet)
  • 🌍 Built Tabi (Live) - Collaborative trip planning platform with RBAC and event-driven notifications
  • πŸ“± Built Shikai - Mobile-first GitHub dashboard with OAuth via Cloudflare Worker proxy and encrypted token storage
  • πŸ”­ Built Recon - Bug tracking intelligence system for QA testers
  • πŸ§ͺ Building Michi (Live) - Client-side router from scratch with nested layouts, data loaders, error boundaries, and prefetch on hover
  • πŸ“¦ Built Reiatsu (npm) - Zero-dependency HTTP framework for Node.js with type-safe routing and built-in security middleware
  • πŸ•·οΈ Built XML Sitemap Generator (Live) - Production-grade crawler with intelligent CSR/SSR detection, BullMQ job queue, and Puppeteer fallback
  • οΏ½ Ask me about Auth/Identity protocols, Backend Architecture, TypeScript, React Native, and Full Stack Development
  • ⚑ Fun fact: When I'm not coding, I'm probably watching movies, diving into a new anime series, or exploring the world with my gf
