About Me

Nebula

Hi, I’m Leonardo, aka DonBigNose—a backend engineer and DevOps expert with a passion for building scalable, reliable solutions. With a background in Physics and Nanoelectronics, I transitioned from scientific research into software development, where I found my true calling: solving complex real-world problems through technology.

I specialize in Python, CI/CD, and Kubernetes, and have experience leading teams to drive system architecture improvements. My journey has taken me across various domains, from fintech to sports data analytics, where I’ve tackled challenges like infrastructure scaling, cloud deployments, and implementing continuous integration pipelines.

Currently, I’m the Co-Founder and Tech Lead at Score Space, a football analytics platform designed to provide real-time and historical data to bettors and analysts. In addition to overseeing the platform’s architecture, I’ve worked on integrating advanced analytics, social engagement features, and secure payment systems. Alongside this, I lead the Engineering and DevOps efforts at my current company, focusing on building and scaling infrastructure that powers mission-critical services.

Tech Stack

  • Languages: Python, TypeScript, JavaScript, Rust (learning)
  • Frameworks & Libraries: Django, Django Rest Framework, Svelte/SvelteKit, FastAPI, Celery
  • DevOps & CI/CD: Kubernetes, Docker, GitHub Actions, ArgoCD, AWS, Ansible
  • Databases: PostgreSQL, MSSQL, MongoDB, Redis
  • Monitoring & Logging: Prometheus, Grafana, Loki, Sentry, PostHog
  • Testing & Quality: Test-Driven Development (TDD), SonarQube, Ruff, Bandit

I’m passionate about continuous learning and staying ahead of industry trends. To that end, I earned the IBM DevOps and Software Engineering Professional Certificate to deepen my understanding of modern software practices. Whether it’s developing end-to-end platforms or leading engineering teams, I strive to deliver impactful solutions that are robust, efficient, and scalable.

Fun fact: I’m also a world champion in table soccer, having competed internationally with the Luxembourgish national team and won titles in both team and doubles categories!
