What I'm looking for

I’m looking for a remote Full-stack Software Engineer role where I can build scalable, reliable, and user-focused products while continuing to grow as an engineer. I’m particularly interested in Full-Stack and AI-focused opportunities involving technologies such as TypeScript, React, Next.js, Node.js, Python, FastAPI, PostgreSQL, cloud services, and modern AI/LLM integrations.

I've built PaySentinelIQ, an AI-powered payment intelligence SaaS that analyzes Brazilian financial documents through a seven-stage multi-agent LLM pipeline and produces five-tier risk scores. I designed its Next.js, FastAPI, PostgreSQL, Redis, LangChain, CrewAI, and PgVector architecture, alongside CI/CD, observability, and LGPD/DPIA documentation.

I also built Pytomatiza+, a configurable AI workflow platform for non-technical users, and ClarkPlayer, a music application with Redis-backed authentication, virtualized media libraries, playlist management, karaoke lyrics, and unified metadata from MusicBrainz, Spotify, iTunes, and Genius.

I'm comfortable owning projects end to end—from schema design, caching, and real-time data flow to Docker deployments across Railway, Vercel, and Cloudflare. My work includes WhatsApp customer-service automation, React Native migrations, and responsive portfolio sites optimized for performance and SEO.
