About

I build full-stack web applications that stay fast, scalable, and maintainable as they grow. I’m Azizul Rabby (Anas) Chowdhury, a Full Stack MERN Engineer focused on performance, clean architecture, and long-term system reliability. I design systems that don’t slow down or break as complexity increases. Most products move fast early — then become fragile, slow, and hard to extend. I focus on solving that from the start. My approach: • Design clear API layers and predictable request flow • Build scalable database structures with efficient querying • Optimize performance across frontend and backend So systems remain easy to extend, debug, and scale. What I build: • High-performance React apps (smooth UX, virtualized rendering) • REST APIs with Node.js & Express • MongoDB schema design, indexing & query optimization • Secure authentication systems (JWT, Firebase) • Performance optimization (load time, rendering, API efficiency) • Production deployments (Vercel, Netlify) Featured Project — DialogueDock A full-stack community platform built end-to-end as a sole engineer: • <3s time-to-interactive • 60fps infinite scrolling on large datasets • 20+ API endpoints with structured architecture • 3-tier RBAC system with zero security bypass I also bring a background in Social Work (MSS), which shapes how I approach systems — with a focus on structure, scalability, and real-world usability. I’m open to remote roles and startup environments where performance and scalability matter. Feel free to reach out via LinkedIn or email: [email protected]

    As a freelance full-stack engineer, I design and deliver production-ready web applications using the MERN stack. I approach projects backend-first — defining API structure, database modeling, and authentication flows — then building a maintainable frontend on top of that foundation. I’ve worked on: • Designing and structuring REST APIs with clear role separation • Modeling MongoDB schemas with practical indexing and performance awareness • Building scalable React interfaces that remain clean as features expand • Implementing secure authentication using JWT and Firebase • Deploying and maintaining live applications on Vercel and Netlify • Optimizing database queries and improving overall application performance A recent example is DialogueDock — a production-grade community platform I built end-to-end, focusing on structured API design, layered role-based access control, and performance-conscious implementation.
