001 — About

Pharmacy to Programming.
An Unexpected Journey.

I'm a self-taught developer with a passion for logic, automation, and AI-driven solutions. I studied pharmacy but unexpectedly fell in love with technology—and never looked back.

Currently working as a Context Engineer and AI Specialist at Bengal Skill Academy (which I proudly co-founded), I specialize in integrating AI into real-world applications using Python, PHP, Go, and modern tools.

My work started with real failures—emails landing in spam, automation breaking silently, AI systems producing confident but wrong outputs. Instead of stacking more tools, I went back to fundamentals: protocols, DNS behavior, execution models, and reasoning structures.

From email infrastructure to AI bots, from automation pipelines to custom SMTP systems—I build systems that don't just work, but work smart.

"The best system is one you forget exists — because it just works."

005 — Philosophy

How I Work.
Principles Over Process.

Reliability First

A system that works 99% of the time fails too often. I aim for infrastructure you can forget exists.

Simple > Clever

The best code is boring code. Clever solutions create clever problems. I choose readable over impressive.

Learn by Building

Tutorials teach concepts. Production teaches lessons. I learn by deploying real things for real users.
