For more than six years, I worked across several areas of a large-scale e-commerce platform, from technical design through production operations. My work spanned the admin frontend built with React and Next.js, the PHP/Laravel core, and specialized backend services, in collaboration with Product, Design, and other engineering teams.

1. Payments platform 2019–2023Each payment provider required a custom integration built by the internal team, slowing expansion into new countries. I helped design a platform with common contracts and a public API, wrote its specification and documentation, and led specific stages of core-service development. During the transition, I worked with partners on adopting the new integration model. Partners then began developing their own integrations, and more than 30 providers were migrated across five countries.
2. Store Activity Logs 2024–2025The admin panel used by each store on the platform lacked a standard way to record and query user actions, making incidents harder to investigate. I designed and implemented a shared service that different product domains could use without coupling their business logic, and deployed and monitored Elasticsearch and Kibana on AWS EC2. Promotions, Catalog, Orders, and Blog adopted it within the service's first six months.
3. Promotions 2024–2025Native promotions were limited to simple discounts, so sellers turned to third-party apps for real campaigns. I contributed to the services of a new promotions engine with combination rules and a public discounts API, and built a Tableau dashboard to measure the discounts' impact on merchants' GMV and average order value.
4. Account & Security 2024Authentication, permissions, and sessions were handled across several domains. I helped design a dedicated security domain, including a data and event model for new security use cases, and contributed to two-factor authentication, session management, and safeguards for higher-risk account operations.

Self-service and academic administration features for students, faculty, and administrative staff. I wrote and optimized SQL queries for frequent operations and took part in migrating the system to SIU Guaraní, working with academic and administrative stakeholders.
