About
Mobile engineering with attention to detail.
I build with what teams need in mind as the codebase evolves, not just what looks good in the first sprint. Clear boundaries, feature-focused modularization, and tests that enable confident refactoring.
- Flutter & Dart engineer with 5+ years building production mobile applications.
- Focus on Clean Architecture, readable code and reusable design systems.
- Strong culture of automated testing, unit tests are part of my definition of done.
- Comfortable working independently or as part of product teams, collaborating with designers, product managers, and other engineers.
- Async-first collaboration: solid PR descriptions and written docs as part of the delivery.

Experience
Where I've shipped.
A few years across product companies and consultancies. Focused on mobile since 2021; a prior background in infrastructure informs how I think about reliability and CI.
Mobile Software Engineer · DB (Consultancy) - PagareFull-time
- Shipped Flutter features for a fintech client under a consultancy engagement.
- Refactored legacy screens toward MVVM, unblocking parallel work between designers and engineers.
Mobile Software Engineer · FITecContract
- Hourly consulting project conducted alongside a full-time role, with flexible scheduling to accommodate both engagements.
- Built and hardened production Flutter modules; wrote unit tests as part of the definition of done.
Mobile Software Engineer · CMOS DrakeContract
- Delivered Flutter features on an IoT-adjacent product with hardware integration constraints.
- Helped set the branching, PR review and CI conventions still used by the team.
Mobile Software Engineer · Raro LabsFull-time
- First full-time mobile role, moved from an infrastructure background into shipping production Flutter across client projects.
- Owned features end-to-end: architecture, implementation, tests and release.
How I work
Engineering principles.
The short version of what shows up in my code reviews and design decisions.
01
Write for the next developer.
Boundaries and naming that hold up after the original author move out. Cleverness has an expiration date.
02
Tests are a design tool.
Coverage isn't the goal, testability is. If a class is hard to test, the design is telling you something.
03
Design systems > screens.
Build reusable components early. Consistency is cheaper to establish than to retrofit.
04
Async-first communication.
Write it down. A good PR description saves three meetings and lets remote teams move across timezones.
05
Ship, measure, then iterate.
Get real usage data early. What users actually do matters more than what we think they'll probably do.
06
Defer the reversible decisions.
Lock in what's hard to change, keep the rest cheap to swap. Architecture is about what you don't decide yet.
