Saifullah AhadOpen to work — remote, hybrid, or on-site abroad
Put an AI engineering system to work for your team.
I built one that ships: 315+ Android apps live on Google Play — specified, verified and released by one person directing AI agents. I can build and run one for you.
Roles
Where I fit on your team
AI Product Builder
Take a real problem to a shipped product with AI agents: the spec, the build, the proof on real phones and the release.
AI Product Manager
Own the product end to end: the problem, priorities, scope, standards and launch.
AI Workflow Orchestrator
Run multi-agent build pipelines day to day — keep them honest, and keep them shipping.
Product Delivery Lead
Take work from spec to release with proof at every step, on time and to the standard.

What your team can expect
- Every piece of work starts with the problem and the acceptance criteria, in writing.
- Specs precise enough for any engineer or AI agent to build from.
- Proof before promises: claims are tested on real devices, with recorded evidence.
- Short, plain status: what is done, what is next, what is blocked.
- Releases handled completely: store listings, policy forms, privacy pages and updates.
- See it in practice: forty-six build stories, from the plan to the proof.

Questions
What recruiters ask me
Do you write the code yourself?
No — and that is the point. I design the system, write the specs and acceptance criteria, and direct AI coding agents (Claude, OpenAI Codex, Google Antigravity) that write the code. Then I verify every release on real phones before it ships. That is how one person runs 315+ live apps.
Can I see the apps?
Yes. Every app is public on Google Play: Google Play developer account. A selection is on the apps page.
Are they real products or demos?
Real products, live on Google Play, each solving a real problem — from off-grid messaging and earthquake alerts to lab-report trends and hearing checks.
Can we review your code?
The repositories are private. In an interview I am glad to walk through the system, the specs and the verification evidence behind any app.
Where are you based, and can you relocate?
Dhaka, Bangladesh (UTC+6). I work remotely in any time zone, can start now, and can relocate to any country with employer visa sponsorship.
