Backend / Full Stack Software Engineer

I am the sole backend and infrastructure engineer for a Spanish proptech startup operating a production real-estate platform with more than 100,000 listings aggregated from approximately 1,000 agency websites. I own the FastAPI REST API, crawlers, servers, deployments, PostgreSQL database, and infrastructure while collaborating in a remote English-speaking Scrum team.

I reduced homepage load time by 84% and improved search performance to approximately 250 ms per page through B-tree and GiST spatial indexes, materialized views, N+1 query fixes, and SQL-based ranking. I migrated production from Azure to Hetzner, reducing hosting costs by about 75%, improved security by resolving SQL injection, account-takeover, and user-enumeration vulnerabilities, and introduced CI/CD, backups, tests, protected branches, and automatic rollback. I also built Stripe subscriptions, Mapbox and LLM integrations, and consolidated crawler systems with data-quality controls.

I built and maintained ES+ Criativo and HUB ES+, production web platforms for the Espírito Santo State Secretariat of Culture that supported more than 1,400 events. I designed the relational data model and implemented backend services and web interfaces using Java, Jakarta EE, JPA, and JSF.

I later led a migration to PHP and WordPress, developing custom plugins for functionality beyond the core platform. I delivered event and venue workflows, registration, cancellation, waitlists, attendance confirmation, recommendations, role-based authentication, reporting, scheduling, and configurable document generation. I also served as an on-call engineer and led delivery meetings with government stakeholders to translate requirements into technical specifications.

I rebuilt the end-to-end test suite for Team Audit, an audit-management web platform, after a user-interface redesign broke the legacy XPath-based automated tests. I replaced brittle XPath selectors with stable element IDs and used Protractor and TypeScript to restore regression coverage across nearly all modules and cross-module data flows.

I also fixed full-stack defects across the Angular and TypeScript frontend, Spring Boot backend services, and REST APIs. My work helped re-establish reliable regression testing before product releases.

BSc in Computer Engineering, expected to graduate in December 2026. Studying in Vitória, Brazil.
