About

• Reduced AWS Lambda execution time by over 50% by parallelizing previously sequential database queries using threads.
• Used Datadog to identify and optimize critical endpoints causing production instability during peak traffic, improving system reliability during the highest-demand period of the day.
• Maintained and evolved production systems serving enterprise clients such as Petrobras, Whirlpool, Gerdau, and Mercedes-Benz, handling 40,000+ requests per day.
• Contributed to the redevelopment of the passenger mobile application using React Native, migrating functionality from legacy web applications, including shift and route change requests.
• Developed passenger-facing applications, including a 24/7 help center and an interactive map for discovering nearby route stops based on user-provided addresses.

• Developed the project from early stage to MVP launch using Next.js with TypeScript.
• Created reusable components to enhance code clarity and facilitate better code maintenance.
• Implemented queries using react-query to efficiently consume and populate the Firestore database.
• Reduced monthly costs from $900 to less than $10 by launching an internal platform called TimeCapsule.

Developing a modular monolith ERP for a handbag manufacturing company from the ground up, applying SOLID, Clean Architecture, and Domain-Driven Design principles. Built the backend with Node.js and PostgreSQL and the frontend with React, integrating electronic invoicing, payment, and shipping services. Deployed the application and database on Fly.io, using Tigris for S3-compatible object storage, and implemented CI/CD with GitHub Actions. Integrated the Hermes agent to enable AI-powered workflows within the ERP.

Developing an application from the ground up, leading requirements gathering and backend architecture using Spring Boot and PostgreSQL. Designed the backend as a modular monolith following Clean Architecture and Domain-Driven Design principles. Containerized and deployed the Spring Boot backend and PostgreSQL database on a Kubernetes cluster running on a Raspberry Pi, with the frontend currently under development.
