// Full-Stack Developer & System Designer
I build scalable, production-ready systems — from thoughtful APIs and robust backends to clean, fast frontends. I care about the architecture as much as the aesthetics.
I'm Arnab — a full-stack developer and system designer with a passion for building software that is both technically sound and genuinely useful. I co-founded Infinite IT, where I lead engineering delivery across web, mobile, and API projects.
My approach to software starts at the architecture level. Before writing a single line of code, I think about data flow, system boundaries, and scalability. I believe great products are the result of disciplined engineering and thoughtful design working together.
I've worked across the full stack — from designing PostgreSQL schemas and building Node.js APIs, to crafting React frontends and deploying containerised applications. I thrive in environments where I can own a problem end-to-end.
When I'm not coding, I'm usually sketching system diagrams, exploring new tools, or thinking about how to make complex things simple.
