About
Lucas Caldas
I build reliable systems across backend engineering, AI agents, and cloud architecture. My work is centered on production-ready services, automation workflows, and platform decisions that hold under real operational pressure.
I focus on clear execution: reducing complexity, improving reliability, and shipping systems that teams can trust in production.
AI Agents & Automation
Multi-agent systems with ADK, Vertex AI, and MCP Toolbox. Agents that integrate Jira, Looker, and BigQuery autonomously.
Cloud Architecture / GCP
Cloud Run, BigQuery, IAM, Pub/Sub, and serverless patterns. Infrastructure that scales without operational overhead.
Payment Systems
Stripe and PIX integrations. Event-driven webhooks, mTLS authentication, and subscription lifecycle management.
Backend Engineering
Python, .NET/C#, and TypeScript. Decoupled microservices, message queues, and high-reliability REST APIs.
