Upgrading and maintaining multiple projects and their dependencies, ensuring compliance (such as PCI), preventing supply chain security issues and current best practices. Significant usage of AI tools like Claude Code to automate and generate preliminary analysis of coding/configuring tasks.

Ensured security, best practices in coding, CI/CD, testing, and documentation within the engineering team. Mentored engineers with 1:1 meetings and throughout the delivery process, handling features for thousands of projects with different payment providers.

Worked on multiple projects of different tech stacks, strengthening experience with cloud, Python, headless CMS, APIs, and back-end for mobile apps. Interviewed dozens of candidates and conducted stand-up meetings in English with international clients.

Worked on ads infrastructure in a high scale product with 60M+ MAUs, both back-end and front-end, for programmatic and direct ads. Operated within a rigorous A/B testing environment when releasing new ad units or changes.

Worked on microservices, headless CMS and GraphQL projects, creating the architecture of one project from scratch while orienting less experienced developers on such technologies.

Worked on microservices, integrating with legacy banking database formats from decades ago with more modern infrastructure. Built a report generator from a legacy database file that reduced generation of a 5GB database report from 1 day to 20 minutes using multi-part upload to S3 and scalable lambda function parallelism.

Developed products and corporate sites for many companies in the Webedia Group and its clients, such as L'Oréal Paris, Tudo Gostoso, and IGN Brasil. Optimized legacy sites more than 10x, with an example from 50s LCP to 4s.

Developed and maintained websites and systems, and developed templates for email marketing. Was the only tech person in the association, acting as support in some cases.

Studied Computer Science at Universidade Federal do Rio de Janeiro from 2013 to 2015, but did not finish the program.

Completed a technical course in Software at Escola Técnica Pandiá Calógeras, concurrent with high school.

Studied Computational Mathematics at Universidade Federal Fluminense from 2011 to 2013, but did not finish the program.
