Senior Software Engineer | Backend & Full Stack | Exploring Applied AI
Brazilian software engineer with 10+ years of hands-on experience building business software, with a strong background in Delphi, commercial automation, and Brazilian electronic tax documents.
I work on REST APIs, desktop applications, and web and mobile products, with an emphasis on reliability, practical troubleshooting, and reducing operational effort.
I'm also studying AI and applied AI, focusing on how they can support software development and business process automation.
-
Production reliability: investigating incidents, inspecting logs and generated SQL, and tracing failures to their root cause.
-
Business integrations: connecting ERPs, external services, and fiscal workflows using ACBr, NF-e, and NFC-e.
-
API engineering: designing integrations with attention to backward compatibility, idempotency, and resilience.
-
Process automation: building background services, scheduled workflows, and tools that simplify repetitive work.
-
AI-assisted development: creating a repository of agent skills organized around domain knowledge, business rules, and development routines to guide AI agents through engineering tasks.
| Area | Technologies |

My work includes:
- ERP and fiscal integrations for Brazilian electronic invoicing.
- Scheduled backup workflows with compression, logs, and cloud or FTP destinations.
- REST APIs and integrations between legacy systems and modern applications.
- Web and mobile interfaces for operational and business management workflows.
Much of my professional work is in private repositories. My public repositories include independent projects, experiments, and learning exercises; their scope is separate from the production experience described above.
I'm expanding my software engineering background with studies in AI and applied AI, with an interest in connecting these capabilities to practical business needs.
- AI-assisted engineering: organizing instructions, context, and reusable skills for coding agents.
- Applied AI: exploring how AI can support existing applications and reduce repetitive operational work.
- Engineering judgment: bringing my experience with reliability, integrations, and business rules to the evaluation of AI-assisted solutions.
My practical work so far includes organizing skills for AI agents. This section describes my current learning direction; it does not imply experience training models or deploying AI products in production.
