I build complete mobile products end to end: native Android apps (Kotlin, Jetpack Compose) connected to custom Node.js / Express backends with PostgreSQL — not just mockups, but real apps shipped to production.
What I can build for you:
- Native Android apps (Kotlin, Jetpack Compose, Material design, push notifications with Firebase/FCM)
- REST API backends in Node.js & Express with PostgreSQL databases
- Web scraping and live data pipelines (marketplace monitoring, lead alerts, price tracking)
- Real-time monitoring apps that scan a source 24/7 and send instant push notifications on a match
- Bug fixes and new features on existing Android or Node.js codebases
Recent work: I designed and shipped a live production app — a native Android "opportunity radar" that scans an online marketplace every 20 minutes, filters out noise with custom rules, scores each result, and pushes an instant alert the moment a match appears. Backend deployed to the cloud, tested against the live endpoint, delivered as an installable APK.
What sets me apart: I ship working, verified software — with real testing, clean handoff docs, and clear communication. Fast turnaround, and I'll show you working code before you pay on small tasks.
Let's build something. Tell me what you need and I'll reply with scope, price and a realistic timeline.
