I build web platforms that scale. With over 4+ years of professional experience, I specialize in architecting multi-tenant SaaS platforms, real-time media systems, and AI-driven full-stack applications. I design deterministic systems where every state transition is intentional, every performance metric is optimized, and every layout is responsive.

• Real-time Biometrics & Media: Developed a finite-state-machine biometric engine on MediaPipe at MyMedicalHub to sustain 60 FPS pose estimation with 99.9% reliability. Built WebRTC video pipelines (OpenTok, self-hosted STUN/TURN) and HTML5 Canvas engines for pixel-accurate data correction.
• System Optimization: Rewrote clinical chatbot states with Redux Toolkit for dynamic routing; refactored 54+ legacy modules into presentational/container structures, eliminating critical memory leaks.
• Cost-Efficient DevOps: Migrated legacy Azure VMs to App Service with automated GitHub Actions CI/CD, reducing overall cloud infrastructure spend by 70%.
• High Performance & Security: Optimized React render cycles to boost frontend performance by 40% (achieving 90+ Lighthouse scores). Deployed HIPAA-compliant SSO (OAuth, strict CSP) and JWT-based REST client layers protected against XSS/CSRF.

Here are some of the open-source projects I've built and currently maintain:

• PostCraft (aipostcraft.vercel.app): An AI-native social-media manager that generates scored, brand-compliant post variants using Google Gemini. Powered by Inngest background queues for non-blocking UI operations.
• DevTools (devtoolsn.vercel.app): A privacy-first developer suite of 40+ browser utilities (differs, generators, regex) with a Next.js App Router backend.
• address-bd (npm package): A zero-dependency, TypeScript-first package providing instant access to bilingual Bangladesh administrative coordinates, Divisions, Districts, and Upazilas.
• Utility Packages: Creator of lightweight, tree-shakeable npm packages like http-status-lite, content-types-lite, and client-parser.

I design for worst-case scenarios — building scalable SaaS systems with predictable state transitions, resilient lifecycles, and reliable asynchronous workflows. Check out my repositories or visit my portfolio to see them in action.
