Working at UpaySoftware 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.

Turns Markdown and TeX from AI study notes into faithful documents, with rendered math and chemistry instead of leftover LaTeX commands, exported to clipboard, TXT, PDF, or DOCX.
Evidence
Live, MIT-licensed, with opt-in real-browser export tests
A local-first Android and iOS finance app for expenses, budgets, savings goals, loans, and recurring income, with one shared Kotlin codebase and no runtime network calls.
Evidence
Open source (Apache 2.0) with CI artifacts; store release not yet configured
A local-first resume builder that turns structured career details into an ATS-friendly resume, a printable PDF, and editable LaTeX source. No account or LaTeX knowledge needed.
Evidence
v1.0.0 released 19 July 2026; v1.1 roadmap published
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.
A small Unix-style file system written from scratch in C: one tool formats a disk image, another adds files to it, with checksums guarding every on-disk structure.
Evidence
Implemented mkfs_builder (formats an image) and mkfs_adder (writes a file and its directory entry) against a precise binary layout.
A two-pass compiler front end that turns C-like source into three-address intermediate code by building an abstract syntax tree first and generating code from it second.
Evidence
Separated parsing from code generation (two passes), so the AST can be inspected and generation stays a clean recursive walk.
02 / How I work
My office workstation and my Mac reach each other, stay awake with their lids closed, and tell my phone when something runs hot. I designed the setup around one rule: never carry a laptop through Dhaka traffic.

03 / Technical profile
A quick read of how I scope, deliver, and build full-stack software and operational systems. Research tools are listed separately as a supporting practice.

04 / Current practice
Production software delivery is the current practice. Independent tools keep the engineering sharp; research remains a separate, evidence-led body of work.
