About
Five years solving real product problems
Front-end with product depth: I understand the business rule before writing the interface.
I've been a developer for over five years, and I've spent almost all of that time inside real SaaS products: tax, financial and logistics systems used daily by rural producers, carriers and accounting offices across Brazil. It's a context that doesn't forgive a slow interface or a confusing flow — if a document fails to issue, the truck doesn't leave.
My work goes beyond shipping screens. I was responsible for maintaining two design systems used across multiple products, led the migration from Next.js to Vite to cut infrastructure costs, and brought deploy time down from 25 to 4 minutes. I like tackling what blocks the whole team, not just my own task.
I hold a bachelor's degree in Computer Science from Atitus Educação, where I researched the feasibility of running large AI models directly on mobile devices. I currently work as a systems developer at Sicredi Aliança, building APIs in Python/FastAPI and automating workflows via API and RPA to reduce manual work across headquarters departments. I also took on, with two classmates, the challenge of building a school-management platform — an idea born in my undergraduate thesis (TCC), closed in February 2026.
Where I'm headed
- Grow into a software architecture role, combining the product and front-end perspective I've built with my current work in back-end, automation and observability.
- Deepen hands-on DevOps — CI/CD, observability and infrastructure as code — building on what I already use at Sicredi Aliança (Grafana, Prefect, GitLab CI).
Where I create the most value
-
SaaS Product
Interfaces for complex systems — tax, financial and logistics — where information density is high and errors cost the user money.
-
Design Systems
Versioned, documented component libraries consumed by several products, with stable API contracts and an automated release cycle.
-
Performance & Core Web Vitals
Diagnosing and fixing real bottlenecks: bundle, rendering, cache and build pipeline. Less JavaScript, more perceived speed.
-
Quality & DX
Automated tests, coding standards agreed with the team, code review, and CI/CD pipelines that shorten the path from commit to production.
-
Architecture & Back-end
I also work directly on back-end and automation — APIs, data integration and observability — combining the product mindset I bring from front-end with infrastructure and scalability decisions.
