About me
I started my career at a local software house, developing systems for regional businesses as a Full Stack Developer trainee. After 7 months, I received an opportunity to join a startup as a Junior Software Developer, where I worked with a new programming language and helped refactor an online course platform.

Work experience

Agência_Vynce

Full Stack Developer & Mobile

Agência Vynce • Self-employed

Jan 2025 - Apr 2026 • 1 yr 3 mos

- Rebuilt the company's mobile app (iOS and Android) from scratch, which had functionality issues and buggy UX/UI, applying an optimistic UI approach with caching via TanStack Query alongside React Native, improving usability by 100%. - Following that result, I was brought in to apply the same strategy to the company's internal logistics system, working exclusively on the frontend (without touching a single line of backend code), which nearly eliminated complaints about slowness and reduced infrastructure costs by 5% to 10%.

Feb 2025 - Dec 2025 • 10 mos

- Tested and validated aeriaLang, a proprietary technology being developed by the startup's founder, which automatically generates a Node.js backend with MongoDB and a Vue frontend from a simple schema, in a fully modular way. - Working on the company's software house side, I built an internal management system for a local construction company, addressing the client's specific business needs. - Was responsible for the design and complete restructuring of an online course sales platform, making navigation 40% faster and smoother.

- Developed full stack features (PHP + MySQL on the backend, Next.js/React on the frontend) for enterprise management systems used by the software house's clients, including internal process automation and role based access control (RBAC). - Built APIs using raw SQL queries and implemented interactive interfaces with SSR/SSG and SWR, focused on performance and fast user feedback. - Worked directly with clients to align requirements and help guide feature development. - Completed my first production deploys and continued implementing new features after launch, marking my first professional experience in software development.
