I'm Ariful. Most people online know me as silverfish.
I'm a BSc CSE student in Sylhet, Bangladesh, and the co-founder and CTO of Zenvy. I build software for small businesses: turf grounds that used to run on a notebook and a phone, and an office in Italy that helps people with their paperwork.
What I care about is software that quietly does its job for people who aren't thinking about software. That usually means plain words, big buttons, prices shown up front, and a database that refuses to let two people book the same hour.
I'm also studying machine learning. The first place I want to use it is Zenvy: forecasting which hours will stay empty, so owners can fill them.

How I work
- Users first
- Before Zenvy's owner app, I watched how a ground manager actually takes a booking: on a phone, between cash payments, often outdoors.
- Ship small
- Small changes, reviewed on a real phone, every week.
- Tests before launch
- Zenvy runs about 900 tests against a real database on every push.
- With AI
- I work with AI coding agents every day. I set the architecture, write the specs, review every change, and own the tests and the trade-offs. You'll see the co-author lines in my commits; I'd rather you hear it from me.
