Choosing the right tools is the easy half. If you need the other half built, that is what I do for a living.
What I build
Web applications
Full products from database to interface: React, Next.js, Angular, Node.js, Express, PHP and Python, with the tests and CI that keep them maintainable.
APIs and integrations
REST APIs, microservices, WebSockets and IoT protocols such as MQTT, LoRaWAN and CoAP, including the awkward integrations with systems nobody documented.
Infrastructure and DevOps
Docker, Kubernetes, CI/CD pipelines, monitoring with Grafana and InfluxDB, and deployments that stop being an event to be feared.
UX/UI and design systems
Interfaces, responsive layouts and design systems built to be implemented, not just presented in a slide deck.
How it works
You describe the problem, I tell you honestly whether I am the right person for it and what it would take. Projects can be fixed-scope or ongoing, and I work with clients anywhere from Barcelona.
The fastest way to start is a short email describing what you need and by when.
Need it built, not just chosen?
Web apps, APIs, infrastructure and interfaces. Freelance from Barcelona, working with clients anywhere.
Recent work
Some of it is public: streaming platforms, ticketing systems, an icon library and a link shortener with analytics. You can see the details on the projects page or in my portfolio.
