BSc in CSE2022
North South University
Started Computer Science & Engineering at NSU, trading “make it work” for “know why it works”: data structures, operating systems, software design, machine learning.

(01)About
Hello, I'm Omi.
I'm Omi, a software engineer finishing a CSE degree at North South University in Dhaka.
It started in class seven, when I was adamant about building a Discord bot for my own server. That stubbornness turned into websites, then mobile apps, then systems: an MLFQ scheduler inside an OS kernel, real-time ride-sharing, privacy-first location sharing, and now PBX software at Automata One. I like owning the whole stack, from schema to pixel, and I bring an applied-ML toolkit along when a problem calls for it.

Operating SystemsNSU
Inside the kernel
Replaced the scheduler in MIT's xv6-riscv with a 3-level MLFQ: 4- and 8-tick round-robin queues, FCFS at the bottom, priority demotion, and a global boost every 100 ticks.

Design patterns, for real
A four-person FastAPI HR & payroll system (RBAC, nested departments, attendance, payroll strategies, PDF reports, audit logs) built on Adapter, Composite, Strategy, Observer, Factory and Facade, with a pytest suite. I later rebuilt it from scratch as CompanyMgmt, a multi-tenant SaaS with database-enforced isolation.

Shipping ResumeX

The capstone
Inference-only N-best rescoring for Bangla speech recognition on a frozen Whisper model. Pipeline on Modal GPUs; MBR rescoring took WER from 34.85% to 32.29% (about 42% of the oracle headroom) and shipped as a video-to-SRT tool.
