No Half Measures.
What I do
Backend & APIs
Scalable, secure backend systems built with long-term maintainability in mind; clean architecture, well-defined APIs, and production-grade reliability.
(.NET, REST APIs, authentication, integrations)
Web Applications
Modern, responsive web applications designed for real users and real constraints; performance, accessibility, and clarity come first.
(Angular, modern frontend patterns, SSR where it matters)
Mobile Applications
Production-ready mobile apps built from UX to deployment; designed to scale, perform, and hold up under real-world usage.
(Flutter, Firebase, end-to-end app delivery)
Beyond just code; shaping requirements, challenging assumptions, and making technical decisions that support the product long-term.
(Architecture, trade-offs, technical ownership)
