Open to work & still learning

Foysal Ahammad

Junior-ish

I'm still pretty new at this, honestly. But I've already built an AI assistant called Agent 24, a few Android apps and a bunch of small tools. My whole process is simple: Google it, break it, fix it, repeat — until it finally ships.

About

A bit about me

The short and honest version — no fake 10× years of experience here.

Who I am

I'm Foysal Ahammad, a developer who mostly builds for Android and AI agents. I'm not the smartest person in the room — I'm just the one who keeps trying until the thing actually works.

My main project, Agent 24, is an autonomous AI coding and technical assistant for Android: a full terminal, a code editor, 31 built-in tools, 13 model providers and a permission system — all running locally on the phone. I built it because I wanted it, and because I had no idea how hard it would be.

What I do

  • Native Android apps (Kotlin + Java)
  • AI agent & tool-calling systems
  • Developer tooling & terminal UIs
  • Crypto / trading utilities
  • Full-stack web (HTML, CSS, JS, Python)

Half of it I learned last week. The other half I'm about to learn next week.
