about
I like problems where the interesting part is underneath: a programming language that speaks Bangla, an energy optimiser that keeps an LLM away from the arithmetic, a forecaster for the air in Dhaka.
This site collects the projects and the writeups that explain them.
now Polishing every project and writing up what I learned.
projects
2026alveelan
A programming language for Bangla-speaking kids. Bangla keywords, digits and error messages, compiled to native code through LLVM.
2026gridwise
Operator notes in plain English become typed constraints, then an exact linear program finds the cheapest 24-hour energy plan.
2026dhaka-aqi
Air-quality monitoring and next-hour PM2.5 forecasting for Dhaka, with a live dashboard.
2026doofen
A scroll-driven 3D agency site. A wireframe building assembles as you scroll, with a built-in CMS for the portfolio.
2026scormplayer
A test harness for e-learning packages. It validates them against the official ADL schemas and logs every LMS API call live.
2025bup-diary
An AI journal you can talk to. It finds your most relevant past entry before it answers.
2025expense-tracker
A desktop finance tracker with income, categories, pie charts and salted-hash accounts.
2024habit-tracker
A dependency-free terminal study tracker with a stopwatch, pomodoro, streaks and per-subject stats.
writeups
How a Pikachu became 7,000 characters
The ASCII portrait on my GitHub profile, step by step. A brightness ramp, ten k-means colours, and an animation that types itself out.
Writing a programming language in Bangla
How alveelan reads two digit systems, answers in Bangla digits, explains its errors in Bangla, and the code-generation bug hiding in nested loops.
Never let the LLM do the arithmetic
In GridWise, a language model reads the operator's notes, but an exact linear program does every calculation. Here's why that split works.
