Things I've built

A Simon-Says-style memory puzzle game with three difficulty levels, streak-based scoring, and persistent high scores — built with Clean Architecture in Jetpack Compose.

UU Study Cloud is a web app where Uttara University teachers share lecture notes, slides and course materials with their classes. Students sign in with their university Google account, choose their department, batch and section, and find every file for their courses in one place. New accounts are approved by an admin, so only real students and teachers get in.

A native Android ERP application built for Uttara University, giving students and faculty a single app to access academic records, class routines, notices, and university announcements.

An android application for readers, built natively in kotlin.

HeyUtho is an alarm clock with no snooze button. When it rings, you have to solve three quick math problems in a row before it goes quiet, and one wrong answer sends you back to the start. By the time you've done the math, you're awake. It's free and open source, with no ads and no account, and everything stays on your phone. The name is Bengali: "utho" means "wake up".

Type a theme like "magical forest animals" and a child's name, pick up to ten pages, and the app makes a coloring book just for them: a cover with their name, then simple line drawings with thick black outlines, downloaded as an A4 PDF ready to print at home. A friendly chatbot sits alongside for kids to talk to while the pages are drawn.

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.

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.

An Android ebook of হে মুসলিম অভিভাবক, a book by শাহরিন ছিদ্দিকা for Muslim parents: on their own self-improvement, on spending for the family, and on the part parents play in shaping their children's character. All 10 chapters ship inside the app, so it reads fully offline with no ads and no account. A "continue reading" card takes you back to your last chapter, and finished chapters are marked as read.

An Android ebook of হে মুসলিম দাম্পত্য, a book by শাহরিন ছিদ্দিকা about the relationship between husband and wife, written as a diary of feelings. All 12 chapters ship inside the app, so it reads fully offline, with no ads and no account. It reopens at the exact spot where you stopped, and you can change the text size, switch between paper, sepia and night pages, and long-press any line to copy it.

A Laravel platform that combines a public site, where people read posts and subscribe, with an admin dashboard for writing, sending and replying. Newsletters are written in a rich-text editor, tested on yourself first, then sent through a background queue. Contact messages become support tickets you can answer by email from the dashboard.

The website for Infancy Academy School in Parulkandi, Kazipur, Sirajganj. Parents can apply for admission online and students can look up their results by class, roll and exam, while the school runs the site from its own admin panel: publishing notices, managing users and admins, and resetting passwords with a one-time code sent by SMS.

A small web app that makes student ID cards for পারুলকান্দি নূরানী তালিমুল কুরআন একাডেমি হাফিজিয়া মাদ্রাসা. The office enters a student's photo, name, class, roll, father's name, address and phone once. The app saves the record and draws the card itself on a canvas, with the madrasa's header, a round photo and every field in a proper Bangla font, then downloads it as a 300 DPI PNG at standard ID-card size.

A browser version of Pong you can play right now, on a laptop or a phone. You're the left paddle, the computer is the right one, and two counters keep score: green for every return, red for every miss. No framework, no build step, just HTML5 Canvas and vanilla JavaScript.

A Java-based airline web application covering flight information, company details, and customer inquiries, built on JSP/Servlets with a Maven build pipeline.
