Work Experience
CTO
ReSpark
- Migrated a monolith into a modular application, unlocking quicker feature delivery, while increasing the reliability of deployments through automated tests.
- Grew the engineering team to three times its original size, deploying processes to reduce the bus factor across various features and support increasing development speed.
- Scaled the infrastructure to support 10x growth in system usage across all tenants.
- Deployed AI features to enable users to automate their processes and have quicker access to data.
VP of Engineering
AvantStay

- Architected, implemented, and oversaw the evolution of all back-end systems supporting public and internal workflows.
- Supported executives in making decisions by connecting multiple data sources through scraping or data polling using ETL processes to form a single source of truth.
- Developed several systems using a reactive approach with Kafka as a message broker and gRPC as the microservices middleware.
Lead Software Engineer
Brazilian Federal Budget Office
- Developed several modules of the federal budget system; was involved in all development phases from requirements elicitation to testing and delivery.
- Designed an architecture based on microservices; including testing, integration, and delivery processes, and a refactoring plan to split the application into independent modules.
- Created a distributed systems library using Scala to ease the migration of a monolith to a microservices-based system, and to offer high availability and scalability by automatically provisioning new nodes.
- Created reusable front-end components to be used throughout the application using Vue.js and TypeScript.
- Acted as a technical leader of a team composed of 15 people.
