Giovani Ferraro Trivelli

Back-End Developer

HarmonyAds — Uruguay

Responsible for the full lifecycle of the company's core OpenRTB 2.5/2.6 bidder microservice — the backbone of the business — built with Java, Kafka/AWS MSK, Elasticsearch/OpenSearch, Redis, PostgreSQL, and Hazelcast. Also designed and maintained supporting microservices for geolocation, data collection, user audiences, and APIs using Python (Django), Java (Spring Boot), and Go. My role included managing Kubernetes deployments, CI/CD pipelines, and documentation, while implementing AI-driven features to enhance automation and decision-making. In addition, I contributed to technical audits, ensured compliance with best practices, and oversaw infrastructure scaling by provisioning new nodes, load balancers, and other resources to maintain high availability.

Full-Stack Developer

Senate of Santa Fe Province — Argentina

Led the migration of the institution's mission-critical back-office platform — the core system used across all areas — from the Java Sofia Framework to a modern architecture with Angular 11+ and Spring Boot, deployed on Docker/Kubernetes with monitoring via Grafana, Prometheus, and Spring Cloud Gateway. After the migration, I focused on frontend development to enhance usability. I also designed and implemented CI/CD pipelines, established development standards and documentation, and integrated Keycloak for secure SSO, while advising the team on best practices for Java/Angular. In addition, I acted as a consultant and technical advisor, guiding the team through technical challenges and evaluating new initiatives.

Notably, I initiated and developed Recinto Digital, a system to digitize legislative sessions that allowed senators to log in, vote, and review projects from their seats; while not used in the Senate chamber, it was successfully adopted for the Santa Fe Constitutional Reform, widely used by legislators, recognized publicly, and featured in the news.

Freelance work consisting in a series of developments for an important accounting firm of Santa Fe, Argentina. They wanted to automate their tasks (without completely abandoning manual work for security), which mainly consisted in collecting data from different websites and parsing it. A solution was developed using a WebExtension to improve the UI of those websites and add features to send the collected data to a backend that writes the information to an Excel workbook.

Helper & Wiki Administrator

Fandom Inc. — USA

Fandom is a free web-hosting service that uses MediaWiki as its engine, focused on wikis related to pop culture such as TV shows, movies, and video games. Fandom is often helped by volunteers ("Helpers") working to support and improve non-English communities on different tasks. My responsibilities were: designing main pages of wikis using wikicode, CSS, and JavaScript; adding CSS to wikis to create unique interfaces that represented the main topic of the website; adding JavaScript to wikis to add or improve Fandom features; and coordinating meetings with Wiki Administrators and attending to their requests.
