Message

At Cyborg Tecnologia, I designed and developed MediaForge / Neural Groove, a browser-based transcription app that processes media without server uploads or data collection. It converts video containers, extracts audio, and uses Whisper AI for speech-to-text transcription with timestamped SRT export.

At Everykey Inc., I implemented APIs, browser extensions, and back-end services for a security platform. I architected a .NET 9 microservice using Clean Architecture and Cosmos DB, and fixed Firefox race conditions affecting authentication flows.

At BairesDev, I worked on education and fintech applications, including Conect+EDU and BMTX. I developed platform modules and integrations, including real-time notifications, authentication flows, and microservices supporting bank-account verification.
