Lucas Cunha

Ships products end to end: UI, APIs, data, AI agents, and the cloud platform they run on.

15+ years shipping full-stack products in TypeScript, React/Next.js, and Node.js, from identity and payments to LLM agents. I own the whole path to production on AWS, so what I build actually runs.

about

I build products end to end: the UI, the APIs, the data model, and the AI agents behind them. Today I'm a senior full-stack engineer at Civic Technologies. I build Civic MCP, a security control plane connecting AI agents to 95+ enterprise tools with guardrails, audit logging, and secure credential management; and Bryn, a signal-based GTM product where LLM agents identify company visitors and act on intent signals in real time.

Before the AI focus, I spent 15+ years shipping full-stack products: a complete identity and authentication platform on Next.js and React, on-chain credentials that scaled past 1M issued, wallet and payment APIs on Node.js, an API-management platform, and video and e-learning platforms. I also own the path to production, so the AWS platform, deploys, and observability underneath my products are mine too.

BSc + MSc in Computer Science from UFMG. Comfortable in TypeScript, Node.js, Python, React, and Next.js, and increasingly in writing the agents that write the code.
