I'm a developer, designer and maker hailing from the mountains of Colombia and based in London — thanks to the UK Global Talent visa.

Interested in working together? Great! Please read below:

I'm an engineer and I specialise in user-facing experiences (web, apps, e-commerce).

✅ Need a full-stack developer with an eye for design? I can help. Projects I developed have made >$50M in revenue, received >$1M in grants, and won awards.

❌ If you're looking for a designer to hire, I probably can't help. I work best as an engineer within a creative team.

Email me at [email protected].

Recruiters: please do NOT contact me about full-time roles or jobs in finance, web3, etc.

Before this, I worked at Google as a Software Engineer (2017 to 2023) and at The Nature Conservancy Brazil, creating tools to stop deforestation of the Amazon rainforest.

Other projects:

• I design and craft modernist silver jewellery at Minilith.co.uk.
• I made flag.london, a proposal for London's missing flag.
• I volunteer as a web developer at Citapress.org, a feminist open-source digital library publishing books by women.
