Selected work
.olnd (The book's DSL) — 📌 Highlighted
I designed a new plain-text format for digital books to solve the usability flaws of PDFs and EPUBs, which often struggle with precise text selection and interactive features. This format acts as a clean 'source of truth' for literature, ensuring that books—especially those in the public domain—maintain their structural integrity and are ready for modern reading experiences and effortless export to any platform.
Go Launcher — 📌 Highlighted
A minimalist, keyboard-driven application launcher for Linux built with Go and the Bubble Tea TUI framework. It’s a fast, low-dependency utility designed to replace heavier GUI launchers in tiling WM setups.
MooviPet
As founding engineer, I was one of the key contributors to the transition from manual spreadsheets to a scalable microservices platform processing over BRL 500k/month. I designed an idempotent booking and checkout system supporting 100+ national terminals and 1.1M monthly visitors. Key technical wins include a vet-facing triage system using AI fine-tuning to automate health-risk alerts and a mission-critical emergency feature shipped in 48 hours during the Rio Grande do Sul floods, which facilitated the rescue of 300 animals.
Olinda
An interactive immersion platform for language learners that prioritizes deep reading over gamification. I built a custom text-selection UX with React and integrated native AI features for instant translations, definitions, and speech generation. By replacing external API dependencies with local bilingual dictionaries processed via Node.js streaming, I reduced API latency by 97% and payload sizes by 85%, creating a near-instant user experience.
Greener
I architected and delivered a robust e-commerce and digital product ecosystem using React, Next.js, and tRPC. I led a comprehensive UI/UX overhaul, replacing fragmented legacy interfaces with a unified, high-performance design system and a custom CMS featuring automated DRM. This strategic migration eliminated manual overhead and streamlined the end-to-end product lifecycle. Beyond the storefront, I engineered a high-performance QA dashboard in Python and React that serves as the central data validation layer for credit risk APIs, and built automation pipelines connecting sales and billing directly to CRM analytics for strategic decision-making.
