Open to work

I build interfaces
for messy work.

Doctors making calls under pressure. QA teams chasing commits. Researchers buried in field data. I like taking messy workflows like these and turning them into software people actually want to open, from the database all the way to the screen, with AI helping along the way. I started as an intern in 2024 and was leading a project by 2026.

The interface is
the product.

About the Developer

I went from intern to project leader in 21 months, and honestly I think it's because I treat the interface as the product, not the paint job. Whether it's an AI platform helping doctors make clinical calls or a VS Code extension that packs commits into QA evidence, the job is the same: find the part of the workflow everyone quietly hates, and make it obvious.

I've led a team, handling architecture, the design system, Git strategy and mentoring, and I never stopped shipping every week. My workflow is AI-native: Claude Code, custom agents and skills that take me from spec to tests to pull request review.

Fun Fact

Fav. Pokémon is Lugia

Psychic-type elegance and legendary rarity. Basically my design philosophy, but as a Pokémon.

Currently Building

Exitus Gestor, across the whole stack. That means a PostgreSQL data model, a Spring Boot domain layer split with Domain-Driven Design and Angular on the front, with TDD, Flyway migrations and Claude Code agents helping out.

Interests

Outside the editor

Pokemon and sharks are my main hype focus: Lugia, Gengar, and Arcanine for personality and style; whale sharks and hammerheads for calm scale, sharp silhouettes, and natural design energy.

Fullstack Engineer

Current · Angular + Spring Boot

Jul. 2026 to Present

Colégio Christus

Structuring Exitus Gestor end to end, so the data model, back-end and interface are all speaking the same domain language. Domain-Driven Design, TDD and an AI-native workflow keep it that way.

Key Achievements

  • Structure Exitus Gestor across the whole stack: PostgreSQL data model, Spring Boot domain layer, and Angular applications integrated with its RESTful APIs
  • Apply Domain-Driven Design to split the platform into services with explicit boundaries and contracts, so each one evolves and deploys without coupling
  • Drive Test-Driven Development, with business rules explicit and covered by tests from day one
  • Version every schema change with Flyway migrations, making database evolution reproducible across environments
  • Build agentic development workflows with Claude Code, with custom agents, skills and automated flows from spec to tests, and automate pull request review with AI

Portfolio

My Work.

Every project here does the same thing: it takes work scattered across tabs, spreadsheets and stuff only one person knows, and gives it one clear interface.
