Description

I help startups, companies and B2B teams design, build and ship production-grade software: AI workflow automation, backend/API systems, SaaS MVPs, web platforms and complex product features.

Through Utsuri Foundry, I work directly with founders, product teams and technical teams from architecture and prototyping to deployment. I’m strongest when a project needs someone who can combine hands-on engineering with product judgment, clear ownership and the ability to turn ambiguous or technically messy requirements into working systems.

Typical projects I handle include:

AI automation and LLM integrations for internal tools, reporting workflows and business processes
Backend systems, APIs, integrations and data flows using TypeScript, Node.js, Rust and Go
SaaS MVPs, internal tools and product engineering for startups and B2B teams
Web platform, frontend and ecommerce engineering: custom features, migrations, performance fixes and technical rescue
Architecture audits, codebase reviews, reliability improvements and technical roadmaps
Blockchain infrastructure, including Solana, EVM, indexers, smart contracts and wallet/protocol integrations

I’m based in Barcelona and work in English, Spanish and Catalan, with experience across SaaS, fintech, web3, Architecture, Engineering & Construction software and B2B platforms.
