Mobile & Desktop App Development
I build Android and cross-platform mobile apps, and JavaFX / .NET desktop applications, backed by production-grade Java or Spring Boot backends. Portfolio examples include Biryan Express — a food-delivery e-commerce app built from scratch with catalogue, cart, checkout, payment gateway, and an operations admin panel — and Pick Plug, where I rewrote a broken Android in-app-purchase flow and fixed the backend subscription webhook, taking IAP conversion errors to zero. I also design mobile experiences: the Modus Media Player project is a 45-screen iOS design system prototyped in Figma.
Ideal for: Field teams, offline-capable apps, cross-platform reach

Common Questions
Do you build mobile apps, and can you fix an existing app's backend or in-app purchase issues?
Yes, both. Pick Plug is a mobile sports-picks app where I rewrote a broken Android in-app-purchase flow end-to-end and fixed a backend subscription webhook that was failing to unsubscribe users — conversion errors dropped to zero after the fix. Biryan Express is a full Android e-commerce app I built from scratch, covering catalogue, cart, checkout, and an admin panel for the operations team. I also build JavaFX/.NET desktop applications when a project calls for a native desktop client instead of, or alongside, mobile.
What does working with you look like from start to finish?
Every engagement follows the same structure: Discovery (understanding your requirements) → Proposal (scope, timeline, and cost in writing) → Build (milestone-based development with regular demos) → Review (your feedback incorporated at each milestone) → Handoff (full source code, documentation, and deployment). You have visibility at every step.
