What I'm looking for

I'm looking to build scalable cloud platforms and distributed systems where I can own technical direction, deliver end-to-end products, and apply TypeScript, Go, Google Cloud, and event-driven architecture.

I've delivered production platforms for Sternwerk Technologies and Alexandre Andreani Advogados Associados, spanning architecture, backend services, frontend applications, and cloud infrastructure.

At Sternwerk, I built Go Center, a revenue-generating B2B SaaS platform for commercial-center room rentals. I designed its multi-tenant TypeScript, Next.js, Node.js, and PostgreSQL architecture and automated contract lifecycles with Google Pub/Sub and Cloud Run.

For Alexandre Andreani Advogados Associados, I delivered Orion, a legal operations platform for workflow automation and large-scale document processing. Its AI-assisted pipeline used Vertex AI Gemini and RAG, while Mailgun-driven asynchronous workflows cut process time by 83%.

I also built a Python metadata-extraction microservice that processed 6,000+ subpoenas across 150+ files, and I mentor interns while continuing self-directed study in distributed systems, system design, and cloud architecture.
