Summary
I have been developing expertise in #Python since 2019. My past work experience has given me solid skills in scientific computing with libraries such as #NumPy, #Pandas and #Matplotlib and foundational understanding of machine learning. Today, my expertise is primarily focused on web development, where #FastAPI, #SQLAlchemy, #SQLModel and #Pydantic form the core of my projects, each integrating suitable libraries based on development requirements.
On the DevOps and cloud side, I implement #CI/CD pipelines using #GitHub Actions, and solid expertise and knowledge of #GCP ecosystem, which host the SaaS I personally built: #Stack-Scout!
I have solid expertise in task queue management primarily leveraging GCP #Pub/Sub and #Cloud Tasks, and I continuously refine my expertise with observability and monitoring tools such as #Prometheus and #Grafana. My development workflow is guided by best practices, including #Pytest and I am comfortable working in #Unix-based OS environments. I have experience designing RESTful APIs, handling both relational (#PostgreSQL primarily) and non-relational (#MongoDB primarily) databases and using #Git for version control.
Beyond backend development, I have solid knowledge of front-end concepts and essential of #JavaScript, allowing me to collaborate effectively on full-stack projects. My continuous learning approach keeps me exploring modern technologies and improving system scalability, performance and observability.
