Drilon Reçica
Senior Mobile & Product Engineer
Android products, practical developer tools, and modern engineering that holds up in production.
I lead Android and mobile product engineering, modernize existing systems, and ship delivery that stands up in production.
Proof
Depth that shows up in production.
Android depth, modernization work, accessibility, and 0-to-1 delivery across very different product environments.
Legacy systems modernized
Moved large codebases away from MVP and RxJava toward maintainable MVVM, Coroutines, Flow, and modular boundaries.
Accessibility that ships
Improved mobile UI quality and accessibility for public-facing products where standards and usability both matter.
0-to-1 product leadership
Led product architecture, backend foundations, and delivery for a greenfield startup product from concept to launch.
Practical builder mindset
Backed by independent products and tools with a bias toward real utility over demo work.
Selected Work
Selected work that shows the level I operate at.
Three projects that show delivery ownership across public mobility, 0-to-1 product work, and customer-facing retail.
Large public mobility product balancing legacy architecture, accessibility requirements, and continuous delivery in a live Android codebase.
- Led migration paths from MVP and RxJava toward MVVM, Coroutines, and Flow in critical parts of the app.
- Improved accessibility and UI consistency while reducing coupling in core product flows.
Outcome Made ongoing delivery safer in a large public mobility app without relying on a disruptive rewrite.

Early-stage product moving from concept to a launch-ready foundation across app architecture, backend systems, and deployment.
- Owned ideation, technical direction, and end-to-end implementation as an early core team member.
- Built the backend in Deno and TypeScript, shipped the Flutter app from scratch, and set up the product foundations around it.
Outcome Took a 0-to-1 product from concept to a launch-ready foundation across product, app, backend, and deployment.

Customer-facing retail product where scan-led shopping flows need to stay fast, clear, and reliable in real store use.
- Built shopping flows linking scanning, in-store actions, and checkout-adjacent interactions inside a large production Android app.
- Improved UI quality and modernization in a retail environment where hesitation directly damages the experience.
Outcome Improved in-store reliability and UX clarity in a product where shopper confidence depends on speed and low friction.

Featured Tools
Practical tools, built the same way.
I build browser-based utilities and public experiments for the kind of technical work teams do every day: fast, local-first, and useful without extra ceremony.
Format
JSON Formatter / Validator
Local formatting, validation, and parse feedback for the payloads you actually work with every day.
Share
QR Code Generator
Practical QR generation for text, URLs, Wi-Fi credentials, email, phone, and SMS with local exports.
Inspect
Regex Tester
Readable ECMAScript regex testing with capture groups, replace preview, and zero dependence on remote services.

How I Work
Clear thinking, durable systems, and product-minded execution.
Principles that shape how I build software, make systems safer to evolve, and work with teams.
Product-minded engineering
I treat product context as part of engineering, not as a separate concern handed over later.
Modernization without reckless rewrites
I move legacy systems forward incrementally, with cleaner boundaries and safer delivery at each step.
Strong mobile foundations
I bias toward mobile architectures teams can maintain under real release pressure.
Ownership beyond the app surface
I am comfortable owning the seams between app, backend, infrastructure, and product decisions.
Collaboration
Open to senior mobile product work, modernization, and selective consulting.
Best fit where product judgment, technical ownership, and reliable delivery matter as much as implementation.
