About Diego

I help startups and product teams turn messy, ambiguous requirements into fast, reliable web applications their team can keep building on. With 20+ years in software and the last decade leading frontend engineering, I bring senior judgment to both the architecture and the day-to-day delivery — so you get something that ships and lasts.

What makes me different:

I own the whole picture, not just the happy path.
I've led engineering on large React, Next.js and TypeScript codebases — data-heavy enterprise UIs, design systems and shared component libraries, complex forms and high-performance data grids — the kind of systems that have to keep working while they change.
I move fast without leaving a mess behind, and I'm as comfortable defining frontend architecture and design systems as I am delivering features under a deadline.
I apply that same engineering discipline to AI integration: LLM-powered features — chat, retrieval (RAG), agents — built to hold up in production, with failure modes, cost and latency handled rather than bolted on as a fragile demo.

Typical engagements:

Building or scaling a React / Next.js / TypeScript web application
Frontend architecture, design systems, performance and code-quality lift
Adding AI features to an existing product without breaking what works
Rescuing and shipping a stalled or half-built MVP
Embedding as a senior/lead engineer in your team

Core stack: React, Next.js, TypeScript, JavaScript, Node. I work fully remote with clients across Europe, the US and worldwide. Tell me what you're working on and I'll tell you straight how I'd approach it.
