Built by one engineer, in public.

Drengr is built by Sharmin Sirajudeen — a software engineer with about ten years building and leading mobile products used by millions across the Middle East, the UK, and India. This is the story behind it.

Why Drengr exists

For about ten years I built Android apps. I was genuinely thrilled when I first found Espresso— Google's own framework, deeply integrated with the SDK, that could simulate real user behaviour. I wrote hundreds of tests. Then reality set in: tests passed locally and failed on CI over animation timing, passed on a Pixel and broke on a Samsung. A designer would move a button into a BottomSheet and forty tests turned red overnight — none of them testing that button. I spent more time maintaining the suite than it ever saved me.

And this was Google's own tool, built by one of the most capable engineering organizations on the planet. If Espresso was the ceiling, the problem wasn't the implementation — it was the entire approach. Appium, UIAutomator, Maestro: each a refinement of the same idea — match elements by ID or XPath, and break the moment the UI evolves. That frustration is where Drengr started. Not from a paper. Not from a hackathon. From years of watching test suites rot faster than we could maintain them.

What I'm building

Drengr is a developer-tools and mobile-analytics platform — a zero-code SDK and cloud service that gives AI agents and engineering teams a framework-blindway to see, understand, and act on any mobile app. It reads what's actually on the screen, not a fragile UI tree, so it covers what nothing else can: native, Flutter, React Native, web-views, and games alike. Built in Rust, with native Android, iOS, and Flutter SDKs and a ClickHouse analytics pipeline.

The path here

I joined Talabatas an early Android engineer when the tech team was about 25 people, and grew with it as it scaled into one of MENA's largest food-delivery platforms — 10M+ installs, later part of Delivery Hero. I work as a staff Android engineer at Floward, a gifting platform across the Middle East and the UK (1M+ installs), where I'm the highest code contributor in their GitHub to date. I hold an M.Tech in Computer Engineering from CUSAT, and I'm based in Dubai.

Building in public

I'm building Drengr in the open — the engineering decisions, the dead ends, and what actually works. The reasoning lives on the blog, and the work-in-progress is in the changelog.
