Systems

Architecture that survives scale

I design software the way serious engineering teams expect: clear boundaries, testable domains, and delivery you can repeat.

Presentation & UX contracts

Composable UI, navigation that respects state, and accessibility-aware flows — without leaking business rules into the view layer.

Domain & application

Use cases, entities, and policies isolated from frameworks so features evolve without rewrite cascades.

Data & integrations

Repositories, caching, offline-first paths, and resilient API contracts — including Firebase, REST, real-time channels, and third-party services.

Quality & release

Automated tests where ROI is highest, feature flags where needed, and CI that protects the main branch.

Principles

Engineering philosophy

I lead with clarity: fewer moving parts, explicit ownership, and decisions that recruiters and CTOs can audit in the codebase.

Prefer boring, proven patterns over clever one-offs.
Optimize for team velocity six months from now — not demo day.
Instrument early: crashes, latency, and business events should be observable.
Security and privacy are part of the feature spec, not a late add-on.
Ship in slices: each release should be safe, reversible, and user-visible.

Timeline

Experience

A track record focused on ownership, architecture, and delivery across mobile and web.
