Know Me
I'm a software engineer at Shabuj Global Education, where I build and maintain the CRM our teams use every day with Laravel and Vue.js, working directly with the business side to turn real problems into working software.
Beyond feature work, I look for places where AI can change how the business runs, and then build it. I proposed and led CAS Shield, an AI-powered mock interview system that prepares students for UK visa interviews, and I'm now leading Nexora, a multi-tenant conversational AI platform that handles admissions leads across chat, email, WhatsApp and voice.
I care about systems that are reliable, auditable and easy for the next engineer to understand: background job pipelines, clear data boundaries between tenants, and a human in the loop wherever AI makes a judgement. I graduated in Computer Science & Engineering with a CGPA of 3.98 out of 4.00.

View all →Check-then-act: the bug that pays users twice
In a take-home assessment, I wrote a withdraw endpoint. To stop duplicate requests, it first checked Redis for the idempotency key, and if the key wasn't there, it saved the key and processed the withdrawal. It looked correct. It passed every test I wrote. And it had a bug that can pay the same request twice. The bug has a name: check-then-act. Once you learn to see it, you find it everywhere: bonuses, coupons, refunds, follows, stock counts, daily limits.
Docker Mastery: The Definitive Guide for Software Engineers
In modern software engineering, the gap between development and production is a major hurdle. Docker has bridged this gap by introducing containerization, fundamentally changing how we build, ship, and run applications.
Why Docker Feels Like a Rocket on Linux but Drags a Little on Windows and Mac
If you've spent any time working with Docker, you've probably noticed something — on Linux, Docker just flies. Containers spin up instantly, everything feels snappy, and the whole experience is smooth. But on Windows or Mac? It's still usable, but there's a noticeable difference. A little sluggish, a bit slower to start up. Why does this happen? Today I want to break it down properly — not in a dry textbook way, but in a way that actually makes sense.
