Mobile Software Engineer (Flutter) • Backend Developer • Bitcoin & Lightning • Rust
I build production-grade mobile applications and scalable backend systems with a strong focus on payments and financial infrastructure.
My work sits at the intersection of:
- Mobile Engineering — Flutter apps with clean UX, animations, and strict flows
- Backend Development — APIs, authentication, databases, and system design
- Bitcoin & Lightning — wallets, transaction flows, security-first design
- Rust Systems — performance-focused tools and backend components
I care deeply about shipping real products, not just demos.
- Flutter mobile apps with clear user journeys and polished UI/UX
- Backend APIs using modern frameworks and scalable architectures
- Bitcoin & Lightning-enabled applications with strong security guarantees
- Rust-based services and tools where performance and safety matter
- End-to-end systems: mobile → backend → payments → infrastructure
🚧 Currently building and polishing flagship projects — coming soon.
