// About

Developer, problem-solver,
and lifelong learner.

Frontend developer with 6+ years of experience building scalable web applications. Started as a support analyst, spent every break studying web development until landing my first dev role. Never looked back.

Worked across e-commerce, team management platforms, and browser-based gaming. Primary stack is SvelteKit with TypeScript, backed by extensive React experience.

Known for strong ownership mentality — I treat every codebase as my own and push for the highest quality without losing sight of business goals. I believe in regular self-analysis and the humility to recognize gaps.

Passionate about mentoring. I aim to give back what my mentors gave me: time, knowledge, and honest feedback. Outside of work, I explore game development, procedural generation, and anything that deepens my understanding of systems.

Senior Frontend Developer

Jul 2025 — Present

Nuuvem — Spawnd

Rio de Janeiro, Brazil · Remote

Building Spawnd — a platform that lets people play high-quality games directly in their browser. Think YouTube, but for games. I own the frontend architecture and sit at the table for every technical decision alongside the CTO, PO, and Designer.

  • Architected the frontend for a console-like browser experience running WebAssembly game builds with multithreading and optimized input handling
  • Shipped critical features for the platform's public launch — on time, with full test coverage
  • Bridge between engineering and product: I translate business goals into technical decisions and push back when needed

Mid-level Frontend Developer

Oct 2021 — Jul 2025

Runrun.it

São Paulo, Brazil

Frontend engineer on a task management platform used by thousands of companies. This is where I grew from a mid-level developer into someone who leads initiatives. I went beyond feature work — I tackled the problems nobody wanted to touch: legacy code, performance bottlenecks, and inconsistent patterns across the codebase.

  • Replaced the bundling pipeline, cutting bundle size and significantly improving navigation speed
  • Led large-scale library upgrades and standardized components and hooks across the entire codebase
  • Established JSDoc typing patterns and coding standards that became the team's baseline for code quality

Frontend Developer

Apr 2020 — Oct 2021

eNe Soluções

Uberlândia, Brazil

My first dev role. Built and maintained the frontend of an e-commerce platform, working across the full delivery pipeline — from component development to CI/CD and deployment. Took ownership of internal documentation early on, something I still carry with me.

  • Delivered React and Gatsby components integrated with Directus CMS and deployed through Netlify
  • Managed complex state flows with Redux and MobX across product catalogs and checkout
  • Became the go-to person for internal knowledge sharing — documented patterns and onboarded new devs

Support Analyst

May 2019 — Apr 2020

Linx

Uberlândia, Brazil

Where it all started. Provided technical support across multiple systems while spending every free moment learning to code. Built chatbot automations that streamlined support workflows — and eventually made the jump to development.

  • Automated support processes by building chatbot skills on the LAIS/Blip platform
  • Hands-on troubleshooting across databases, environments, and client-facing systems
