Full-stack app developer — I build native Android apps and the Node.js backends that power them, shipped to production.
I'm a full-stack app developer specializing in native Android apps (Kotlin, Jetpack Compose) and the Node.js backends that power them. I build complete mobile products end to end — app UI, REST API, database, live data pipelines and cloud deployment.
Most recently I designed and shipped a live production app: a native Android "opportunity radar" that scans an online marketplace 24/7, filters results with custom rules, scores each one, and sends an instant push notification the moment a match appears. The backend runs on Node.js + Express with PostgreSQL, deployed to the cloud and verified against the live endpoint.
What I can do for you:
- Native Android apps (Kotlin, Jetpack Compose, Firebase push notifications)
- Node.js / Express REST backends with PostgreSQL
- Web scraping, data pipelines and real-time monitoring / alert tools
- Bug fixes and new features on existing Android or Node.js codebases
How I work: clear scope up front, honest timelines, real testing before handoff, and working code shown before payment on small tasks. I ship — no abandoned demos.
Let's build something. Tell me what you need and I'll reply with scope, price and a realistic timeline.
Work Terms
Availability: flexible hours, responsive during European daytime (CET) and adaptable to your timezone.
Communication: I give clear, regular updates and reply quickly. English and Spanish.
Payment: milestone-based or upfront for small tasks, through Guru SafePay. For small jobs I'm happy to show working code before payment.
Turnaround: fast for bug fixes and small features; larger builds are scoped with a fixed timeline up front.
