Lisbon, Portugal
Hey, I'm Diogo
Senior software engineer and solopreneur based in Lisbon, Portugal. I craft scalable, high-performance web apps and indie products — and I write about the journey.
What I do
React & Next.js
Fast, scalable applications built on the modern React stack — SSR, RSC, and everything in between.
TypeScript
Type-safe codebases from design systems to production APIs, so refactors stop being scary.
AI workflows & harnesses
Agent pipelines and evaluation harnesses that turn LLMs from demos into reliable, shipped product features.
Performance
Core Web Vitals budgets, code-splitting, and measurable speed improvements on every project.
Testing
Unit, integration, and end-to-end coverage you can actually trust when shipping on a Friday.
Design Systems
Component libraries and micro-frontend foundations that keep teams shipping consistently.
By the numbers
