Achievements: • Contributed to the development of the product through an agile process. • Contributed to creating of a baseline for implementing E2E tests in a hybrid stack. • Identified several conditions under which the system could fail by load-testing it. • Played a facilitator role in several sprint retrospectives. Technologies: Python | FastAPI | Django | SQLAlchemy | Postgres | Kanban | Pytest | Continuous Integration & Continuous Deployment (CI/CD) | Linux | Docker | Domain-driven design (DDD).

I worked in a small software development team following an agile workflow. I participated in the entire software development lifecycle, with main focus on facilitating teamwork and improving productivity by implementing DevOps practices. I took part in the development of several web applications and maintained our development, deployment and monitoring infrastructure. Technologies used: Django, Vuejs, GitLab, Nexus, Docker Swarm, Portainer, Grafana, Prometheus, Loki and Traefik.

I taught undergraduate courses at the Faculty of Computer Science and Exact Sciences. Some of the taught subjects: Introduction to software configuration management; Multimedia programming; Agile methods; Mobile programming. Member of the Advanced Databases and Information Systems (ADIS) scientific research group.

Achievements: • Improved codebase quality by using well-known patterns and refactoring existing code. • Reduced CI/CD pipelines execution time by a third. • Identified relevant SLI and SLO. Configured their continuous monitoring and the issuance of alerts when their values fall outside acceptable limits. • Integrated the system with several payment solutions. Technologies: Python | Django | RESTful API | TypeScript | Angular | Linux | Amazon Web Services | Infrastructure as Code.

Developed a web application for managing gamified courses. Key challenges: adding a GraphQL API, setting a baseline for Learning Analytics, and improving UX to bring it closer to real-time classroom usage. Followed an agile approach.
