Summary

AI Product Builder with 3+ years of experience and 315+ Android apps live on Google Play through one developer account. I translate real human problems into precise specifications, direct specialized AI coding agents, and own device verification and release quality from idea to upkeep.

Rapid Android app delivery: I help founders, businesses and agencies turn product ideas into fully tested, production-ready Android apps on Google Play in 7–10 days, at a fixed price of $600 – $1,200 depending on scope (50% upfront).

Selected projects

AI coding agents built each app from my written specification. My work was the specification, the tests it had to pass, and the review.

Ugong: Vehicle Sound Check — live on Google Play

saifullah.ai/work/ugong

  • Would not accept “done” until the sound analysis had really run: an agent had marked the app ready after only opening it. The real run exposed three bugs; all three were fixed and an automated test was added.
  • On the final release build, a 400 Hz and an 800 Hz test tone gave two different results, both with high confidence, so the app measures rather than guesses. Checked on an Infinix phone and a Galaxy Tab S3.

Eelj: Harvest Queue — live on Google Play

saifullah.ai/work/eelj

  • Specified how one shared harvesting machine is ordered across a village’s fields: by which field is losing grain fastest, not by who shouts loudest.
  • Signed release build tested on two devices with a real field: all six screens worked, results survived a restart, the day’s plan matched on computer, phone and tablet, and 17 of 17 automated tests passed with zero crashes.
