• Delivered and maintained production REST APIs for core hospital workflows (telemedicine, appointment scheduling, login/auth), ensuring reliability, performance, and security.
• Built NestJS/TypeScript microservices with unit and integration tests (Jest), structured error handling, and observable logs with correlation IDs.
• Owned CI/CD pipelines on Azure DevOps (build/test/lint/release gates, artifact versioning, environment promotion, rollback paths).
• Managed AWS workloads (ECS/ECR, RDS, DynamoDB, Lambda, API Gateway, SQS/SNS, CloudWatch) and supported networking (VPN, NLB, subnets).
• Contributed to frontend (React) by shipping small admin screens/forms (CRUD, tables, filters) integrated with backend APIs, adding client-side validation and basic tests to unblock end-to-end delivery.
• Collaborated with product and operations teams to triage incidents, maintain runbooks, and enforce operational hygiene through alerts, dashboards, and post-incident improvements.

• Designed and shipped failure-aware reprocessing and targeted backfills for large batch pipelines, transitioning from full reruns to selective retries by dataset/partition, significantly reducing manual intervention.
• Built Azure Functions and Python services to orchestrate ingestion and validation at scale, incorporating structured logging, correlation IDs, and actionable alerts, improving triage and reducing on-call noise.
• Developed CLI tooling (Python + SQL) to list and match blobs, detect missing partitions/files, and safely trigger replays, accelerating recovery from failures.
• Hardened CI/CD pipelines for Databricks and Azure Functions (build/test/lint, promotion, rollback), enabling cleaner releases and faster recovery from deployment issues.

Worked as part of the web integration team for one of the largest retailers in the country as an employee of Stefanini. Surveyed specifications for new integrations, implemented API RESTs, and documented the process.

Comgás:

• Developed and optimized Node.js/TypeScript microservices for housing-contracting workflows (auth, validations, orchestration), running in Docker/Kubernetes (AKS) with observability via Datadog.
• Owned CI/CD pipelines on Azure DevOps (build/test/lint/release), container image hardening (ACR), secrets management (Key Vault), and basic networking, enabling safer and repeatable releases.
• Contributed to frontend (React) by shipping small admin views and forms (CRUD, tables, filters) integrated with APIs, adding client-side validation and unit tests (Jest/Testing Library) to accelerate end-to-end delivery.
• Improved service stability and diagnosability through standardized logging and monitoring, and reduced handoffs and lead time by integrating focused React UI changes with backend APIs.

Zag:

• Built and maintained Node.js/Express microservices for internal workflows and improved the CI pipeline by implementing a consistent GitLab Flow and contributing to internal CI/CD libraries.
• Managed a hybrid delivery setup (GitHub + GitHub Actions + AWS EC2/ECR + Rancher), standardizing container builds and deployment conventions to reduce release friction.
• Contributed to frontend (React) by implementing lightweight admin tools (dashboards, tables) consuming backend services, and created reusable components and API helpers to streamline product workflows.

• Gathered technical specifications and designed, implemented, and documented RESTful APIs to support web integration processes.
• Developed with Python (Django REST, Flask) and PostgreSQL, maintained a Dockerized development environment, and wrote automated tests to ensure reliability.
• Collaborated with cross-functional teams to ensure quality, performance, and stability of backend services, and standardized OpenAPI documentation to accelerate onboarding and handoffs.
