About

I am Lucas Guerra, a software engineer. I design and operate complete information systems, from development and security to infrastructure and applied artificial intelligence.

Full-stack development

I build business applications, interfaces, APIs and connectors between systems. I start from the need, structure the data and deliver a usable, maintainable and documented product.

DevOps and infrastructure

I handle environments, containers, CI/CD, hosting, observability and operations. The architecture is designed to remain reliable, manageable and cost-effective in production.

Cybersecurity

I integrate security from the start: identity and access management, hardening, segmentation, backups, traceability and protection of application-to-application exchanges.

Applied artificial intelligence

I build AI agents, assistants, RAG systems and automations connected to business data and tools. Evaluations, permissions, guardrails and supervision make them dependable in real-world use.
