Software Development / Project Management
Scope · Systems · Delivery
I'm a Software Development Officer at Upay and a BRAC University Computer Science graduate. I take operational problems from discovery and architecture through full-stack implementation, hardening, and production rollout.
My research is a separate practice focused on multimodal learning for incomplete clinical data. Across both tracks, I care about ownership, auditability, validation, and what happens after delivery.

A live conversion workspace that turns Markdown and TeX-heavy AI study notes into consistent previews, clipboard output, TXT, PDF, and DOCX documents.
Evidence
Live multi-format document workflow with diagnostic and source-fallback paths
A local-first Android and iOS finance app for expenses, budgets, savings goals, loans, and recurring income—built with shared Kotlin Multiplatform architecture and no runtime network dependency.
Evidence
Cross-platform local-first finance tracker with a documented privacy boundary
A next-generation resume/CV builder that outputs pure LaTeX for flawless typesetting and PDF quality. Designed for professionals, researchers, and students who demand beautiful, ATS-friendly resumes with zero coding required.
Evidence
Deployed at zerotex.vercel.app with live editing and LaTeX export
Hover to run gameplay
A 3D Battle Royale shooter built entirely from scratch in Python using raw OpenGL fixed-function pipeline calls. Features a custom first-person renderer without any existing game engines, implementing hand-written collision physics, wave-based AI, and a fully functional weapon/ammo economy.
Evidence
Custom 3D rendering pipeline using raw OpenGL (fixed-function) without shaders or game engines.
Single-handedly designed and implemented a complete virtual file system from scratch in C. Features custom superblock management with CRC32 checksums, Unix-style inode system, and utilities for creating and managing VSFS images.
Evidence
Complete VSFS initialization with metadata storage and integrity verification.
Two-pass compiler transforming C-like source code into three-address intermediate code using Abstract Syntax Tree (AST) based code generation. Implements complete compilation pipeline from lexical analysis to intermediate representation.
Evidence
Full compiler front-end with Flex lexical analysis and Yacc/Bison syntax analysis.
03 / Current practice
Production software delivery is the current practice. Independent tools keep the engineering sharp; research remains a separate, evidence-led body of work.
