About

I’m a software developer and technical project lead based in Argentina, with time spent living and working in Berlin, Turin and Boston.

From 2023 to 2026, I co-founded and led development at Lumios Digital, delivering e-commerce stores, websites and digital products for international clients. I managed projects from discovery and technical scoping through development, testing, deployment and support.

Today I work directly with brands, agencies and product teams across Shopify, WordPress, React and native macOS development. I’m equally comfortable implementing a polished design, solving a complex integration or owning the full project from initial requirements to launch.

I speak English, Spanish and Italian and work remotely with teams across the Americas and Europe.

Thesis

Companies hiring someone to build a website or digital product usually face the same trade-off.

An agency gives you a team, but every layer adds cost, delay and distance between the people making decisions and the person building the product. A project manager speaks to an account lead, who speaks to a designer, who then hands the work to a developer who was not in the room when it was scoped. Context gets diluted at every handoff.

An execution-only freelancer gives you the opposite problem. The structure is leaner, but you become the strategist and project manager. You get what you specified rather than what the product needed, because nobody on the other side is responsible for seeing the whole thing.

I offer a third model: one person who takes responsibility from the first conversation through production and beyond. I scope the work, shape the architecture, design where needed, write the code, deploy it and support it. Nothing is handed off, so context stays intact and decisions move faster.

That model used to put a hard ceiling on what one person could deliver. It does not anymore. AI-assisted development compresses the mechanical parts of the work and leaves more room for judgment: what to build, how to structure it, where to simplify and what will still hold up a year from now.
