About Me
Software engineer based in Dhaka. I've been writing code since high school, started with C and Linux, and gradually worked my way up the stack. These days I work on backend systems, security, and AI tooling — mostly in C#, Python, and Go.
I enjoy understanding how things work at a low level, and equally how different systems integrate, communicate, and give rise to something new. Outside of work I'm into the outdoors, reading, and the occasional late-night rabbit hole.
Projects
GenericAI
2024Agentic AI assistant built on the ReAct framework. Integrates LangChain, Gradio, and MongoDB — capable of web browsing, PDF analysis, image interpretation, and persistent memory across sessions.
Facial Expression Recognition
2022CNN-based vision system for real-time facial expression and mood classification. Built during university — trained and competed in Vision AI contests and Kaggle challenges.
microOS
2020Minimal OS built from scratch — custom bootloader, IDT interrupt handling, VGA display, and keyboard driver. Runs on QEMU or bare metal via USB.
klogger
2020Linux kernel module keylogger that captures all keystrokes system-wide, fully undetectable — no syslog traces, no process visibility.
Tao's Adventure
2019Cross-platform 2D platformer built from scratch with 200+ commits. Multi-world level design, physics, collision, and keyboard controls — no engine, just C++ and SFML.

Experience
Software Engineer
Orbitax
Mar 2024 – Present
Database modernization, microservices, security hardening, cost optimization. Worked across the stack — migrated SQL Server to MongoDB, built a Python CQRS service bridging SignalR with RabbitMQ, tightened up CSP and RBAC on the identity platform, and helped ship XatBot, an LLM-powered tax assistant over a 70k-document corpus. Also integrated XatBot into Claude Connectors via OAuth.
Associate Software Engineer

Remediated critical SAML SSO misconfigurations flagged by a Big 4 audit firm and assumed full ownership of the legacy Identity Provider. Stabilized passwordless MagicLink login, implemented RFC 6238 TOTP multi-factor authentication, and decoupled the admin application onto an isolated domain to reduce public attack surface. Delivered Net Operating Loss calculation module .
Software Engineer Intern
Orbitax
Sep 2021 – Feb 2022
Ported a high-throughput .NET microservice to Go — achieving 60% latency reduction and 70% memory reduction. Built automated JMeter load-testing infrastructure via batch scripting, and contributed data-extraction tooling to the internal workflow engine. Converted to full-time on completion.
