About
Born in Edmonton, Canada but raised in Southern Brazil, you can speak to me both in English and Portuguese. Currently living in beautiful British Columbia, I'm a remote senior software engineer specializing in enterprise web applications and AI-powered automation — systems where LLMs do the heavy lifting and a human stays in the loop where it counts.
Current Focus: AI agent systems with Claude — trading-signal analysis, industrial IoT anomaly detection, and government-site automation.
Experience
What do I do?
I lead backend engineering on the email delivery team — the platform
responsible for getting Workday's email to enterprise customers reliably and at scale.
As Tech Lead I set the technical direction, drive the architecture, review the team's
code, and unblock delivery — while still designing and shipping services myself.
Tech Stack:
- Microservices backend with Java + Spring
- REST APIs
- Kafka + PostgreSQL databases
- Kibana + Grafana
What have I done?
- Dispute Automation: Designed and built a Kotlin + Spring Boot microservices decision engine that automated ~20% of disputes end-to-end, cutting resolution time from days to hours and reducing operational bottlenecks.
- Event-Driven Systems: Integrated microservices with Kafka for real-time processing, improving transaction handling and case tracking.
- Observability & Metrics: Built Prometheus/Grafana dashboards and custom Micrometer metrics (e.g., dispute resolution, credit issuance) to give risk, compliance, and ops teams visibility into system performance.
- Scalable Architecture: Contributed to high-availability services and APIs, applying modern engineering practices (Testcontainers, Kotest/Mockito, CI/CD pipelines).
- Cross-Team Collaboration: Partnered with risk, compliance, and operations teams to translate complex financial regulations into decision logic.
Tech Stack:
- Microservices Backend with Spring Boot + Kotlin
- gRPC/Protobuf/Kotlin
- Kafka + PostgreSQL databases
- AWS (Amazon Web Services)
- Prometheus + Grafana + Micrometer, Kibana
- Testcontainers, Kotest/Mockito, CI/CD pipelines
What have I done?
- Have helped lead the development of new microservices and have built APIs that process streaming data to power customer purchases from over 400 pharmacies which resulted in a new record net profit for the client of over R$ 24 Million (US $4.55 Million) in the second trimester of 2021. An annual incremental of 3x the revenue of the same period last year.
- Ensured the development artifacts are in alignment with patterns/ frameworks designed by software engineering teams.
- Developed and expanded applications using standard frameworks from Spring Suite and up to date coding standards.
- Conducted code reviews. Helped guide team development and helped new junior developers for continuous improvement of our team.
