Why I built it

The first version was a basic reader. I redesigned it as a modern ebook that gets out of the way: a proper Bangla font, Bangla numerals, a progress bar on every chapter, and page colours that are easy on the eyes at night.

My role

Every SSC and HSC board question, sorted so you can find it in seconds

An Android and iPhone app that brings past board questions from all 11 education boards of Bangladesh into one place, from 2015 to 2025, across 66 SSC and HSC subjects. Pick a subject, board and year and the full paper opens, or revise chapter by chapter and see which questions keep coming back. It works offline with no login. The current beta ships with sample questions in the real board format, clearly marked in the app, while the full paper set is added.

Case study

GridOptima

Turns an operator's plain-English notes into the cheapest valid 24-hour campus energy plan

My entry for the BUP CSE Fest 2026 hackathon's Smart Campus Energy Optimization Challenge. A campus runs on solar panels, a battery and the grid, and operators leave notes like "keep at least 40% in the battery overnight". GridOptima reads those notes with a language model, checks every rule it extracts with deterministic guardrails, then solves for the minimum-cost hour-by-hour schedule and replays it to prove it's valid before answering.
