About

Software engineer focused on backend, infrastructure, and distributed systems. I've shipped production code for high-availability systems — from bank-scale payment processing at BMP to real-time industrial automation at WEG. I care about cost, observability, and systems that are maintainable long after the first deploy.

Experience

Mid-level Software Engineer@Banco BMP

Oct 2025 – Present

Joinville, SC · Hybrid

Largest Banking as a Service (BaaS) platform in Brazil, moving over R$60B/year behind the country's top fintechs.

  • Participated in the migration of critical payment queues from a .NET Framework 4.6.1 monolith to serverless microservices using AWS Lambda, SQS, and SNS.
  • Cut existing Lambda processing time by ≈62% via cold-start reduction, business logic refactoring, and concurrency tuning — direct impact on AWS cost and payment settlement speed.
  • Used Datadog to identify latency bottlenecks, N+1 queries, and poorly optimized DB access, reducing average SQS message processing time by 41% without infrastructure scaling.
  • Delivered performance and UX improvements to the legacy AngularJS front-end and optimized API endpoints, reducing average response time by 43% and cutting operational complaints about system slowness.

Software Engineering Analyst@WEG

Mar 2024 – Oct 2025

São Paulo, SP · Remote

One of the world's largest manufacturers of electro-electronic equipment, with presence in 40+ countries. Worked in the Industrial Automation division building MES solutions.

  • Architected a shop-floor data ingestion solution using AWS IoT Core, SQS, and Lambda with real-time delivery via SSE; used PostgreSQL with TimescaleDB for sensor time-series persistence, supporting ≈100,000 events/min at <2s ingestion latency.
  • Implemented IaC with Terraform (state lock via DynamoDB + S3) integrated into CI/CD pipelines, ensuring infra and code evolved together and eliminating environment drift.
  • Built modular CI/CD pipelines (test / SonarQube scan / build / deploy) adopted by 3 teams, standardizing delivery and eliminating 100% of production incidents caused by manual deploys.
  • Set up an observability stack from scratch with Prometheus, Grafana, and AlertManager, uncovering 12 previously invisible bottlenecks and improving average API response time by 31%.
  • Developed authenticated public APIs for ERP integration, exposing real-time production data and eliminating manual reports that consumed ≈3 hours/day from the operations team.
  • Worked full-stack with .NET Core, Go, React, and Angular; led code reviews and wrote E2E tests with Playwright covering all critical user flows.

Software Engineering Intern@WEG

Oct 2022 – Mar 2024

São Paulo, SP · Remote

  • Built interactive Angular 16 dashboards with AgGrid and G2Plot used by 200+ factory managers, consolidating multi-source data into a single interface replacing manual spreadsheets.
  • Refactored critical SQL Server queries responsible for bottlenecks on high-volume endpoints and implemented cache-aside on most-requested endpoints, achieving up to 67% response time reduction.
  • Refactored and organized code to follow RESTful patterns and Clean Architecture, reducing time spent on planning new features and fixing bugs.
  • Integrated SonarQube as a mandatory quality gate, reducing operations and support tickets by 43% over the period.
