Leonardo Barbosa
Software Architect · Winter Garden, FL
Twenty years building scalable, reliable systems end to end: infrastructure, databases, APIs, and the interfaces on top of them.
What I do
- Agentic AI systems
- MCP servers, subagents, hooks, tool orchestration, and multi-agent workflows. Provider-agnostic across Anthropic, OpenAI, Google, and open-weight models, built to real cost ceilings, latency budgets, and compliance boundaries.
- Cloud architecture
- Production systems on AWS, GCP, and Azure. Cloud Run, ECS, Lambda, Kubernetes, Postgres, and the Terraform and CI underneath them.
- Product engineering
- TypeScript and Node.js backends, React and React Native front ends, GraphQL and REST APIs. Postgres, Redis, and BullMQ, with the indexing, partitioning, and zero-downtime migrations that large tables require.
- Industries and compliance
- Healthcare, life sciences, commerce media, retail, and high-volume consumer platforms. Systems built under HIPAA, 21 CFR Part 11, SOC 2, and ISO 9001: PHI at rest and in transit, validated quality systems, and audit evidence pipelines.
