Who are you?

I'm Leo (he/they)! Welcome to my little place on the internet. It's a bit messy, but do make yourself at home. I do quite a bit, including…

• Principal Software Engineer (Web & Platform) at Lumi
• Innovation and Outreach Lead at Voxa
• OpenInfra Summit Europe 2025 Programming Committee member and Student Engagement Committee member
• community organiser for codebar
• thing-doer for Not Another Pizza
• conference speaker
• being a matchmaker, hyper-social being and overqualified friend

What are you interested in?

I contribute to open source (mostly in TypeScript), organise events and speak at conferences. The guiding principle of my career (and to some extent, my life) has been to help cool people do cool shit.

I use my site as a home for all my projects on the Internet, as well as to share what I learn. I'm big on hosting my own services when I can, instead of relying on cloud providers. Learn more about this here.

Right now, my focus is on…

• Self-hosted services
• Decentralisation and personal data privacy
• Community and event organisation, and tech meet-ups
• Open data
• Gaming
• Developer tooling and internal tooling

What would you like to learn more about or get into?

• Lego!
• Machine learning, particularly from first principles
• Photography
• Embedded software
• Reverse engineering and cybersecurity
• Computer networking
• CNC machining and 3D printing

Where have you spoken?

I've spoken in (in order of most enjoyed to least enjoyed)…

• Barcelona, at uncodebar in November 2023 and at uncodebar in November 2024
• Vienna, at HalfStack in September 2023
• Glasgow, at uncodebar in November 2023
• London, at HalfStack in November 2024, codebar Festival in March 2024, codebar Festival in September 2023, HalfStack in November 2022 and uncodebar in October 2022
