A mind
in motion.

I’m Foysal—a student, builder, and incurably curious person from Bangladesh. I make tools, ask questions, and bring people together.

01 — 07 / Selected work

Different interests.
A common impulse.

Notice something. Try to understand it. Make something useful. These are a few of the places that has taken me.

01 /Community / Humanitarian work

Small beginnings.
Shared responsibility.

Co-founder & Executive Director

A bottle of water in a Dhaka heatwave became a youth-led platform for food support and emergency relief. I co-founded Hashi Ekshathe and lead its projects, partnerships, and volunteer coordination.

From a file
to a physical thing.

Founder & developer

I built a manufacturing platform that turns uploaded 3D geometry into a price. The same design–print–test loop supports my longer-term work on drone research and production.

Students are using AI.
What comes next?

First author · Study designer

My first-author study examines how Bangladeshi secondary and higher-secondary students use AI, reason about its ethics, and navigate a lack of institutional policy. I designed the survey, collected 278 responses, analyzed the data, and wrote the manuscript.

Built around
the student desk.

Founder & developer

Board questions in one place. Notes somewhere else. A study plan that never quite stays together. I started Khata to bring the everyday work of HSC preparation into one platform.

07 /Open source / E-ink firmware

I wanted to read.
Then I changed
the reader.

Author & maintainer of the NEOINK fork

My reading habit became a firmware project. NEOINK extends CrossInk for the Xteink X3/X4 with flashcards, Markdown reading, a richer library, and themes.

A note between chapters

Sometimes the next project begins with a problem. Sometimes it begins with a book, a conversation, or something I can’t leave alone.

I’ve learned to follow that feeling—and then do the less glamorous work of making the idea real.

There’s more
in the margins.
