From billion-row databases to multi-agent systems, with a soft spot for cross-platform apps
📍 Vitória, ES — Brazil
- 🗄️ I like the hard parts of databases: multi-terabyte PostgreSQL, billion-row tables, autovacuum tuning, online index builds, and connection pooling.
- 📨 I build event pipelines: high-volume consumers, batch inserts, prefetch/ack tuning, and autoscaling that follows the queue.
- 🤖 I build with LLMs end to end: RAG, agents and multi-agent architectures, tool use, fine-tuning, evaluation, and guardrails.
- 🧱 Polyglot by necessity and by taste: Go, TypeScript, Rust, .NET, Python, Kotlin, Swift, and more.
- 💙 Cross-platform apps are my soft spot: Flutter, React Native, Tauri, and Electron.
- 🧑🏫 I enjoy teaching and writing clear, step-by-step explanations.
- ☕ Coffee is necessary.

AI
| Area | What I work with |
|---|---|
| Retrieval | RAG pipelines, embeddings, chunking strategies, vector databases |
| Agents | Agent and multi-agent architectures, function calling and tool use |
| Orchestration | LangChain, LlamaIndex, CrewAI |
| Models | LLM, SLM, and multimodal model APIs, local models, fine-tuning |
| Prompting | Prompt engineering and structured output |
| LLMOps | Evaluation, benchmarking, and observability |
| Safety | AI security and guardrails |
| Area | What that means in practice |
|---|---|
| PostgreSQL at scale | Autovacuum tuning on very large tables, CREATE INDEX CONCURRENTLY, JSONB, connection pooling, storage and bloat investigation |
| Message-driven systems | RabbitMQ consumers, prefetch and ack strategy, batch writes, backpressure |
| Kubernetes | Running and scaling workloads with HPA, debugging networking, day-to-day operations |
| Infrastructure as code | Terraform, Docker, Linux |
| Backend services | Go consumers and NestJS + TypeORM workers built for throughput |
