About

From backend engineer to technical leadership.

I design and lead systems that have to respond under real load: availability engines, provider integrations and booking platforms in production.

Background

At Sidetours (Palma, 2024–2025) I joined as a software engineer on a B2B platform for booking tours and experiences, and grew into architecting its high-performance systems. At the core was an availability engine handling on the order of 5 million requests per hour at peak, supporting an average of 1,000 to 1,500 bookings a day.

Much of that system was legacy and vanilla PHP. That forces a very specific discipline: you cannot rewrite everything, so you learn to identify which part of the critical path actually hurts and modernise it without stopping operations. Alongside that I worked on the infrastructure — horizontal autoscaling and master-slave replication on AWS, with Nginx and Redis in front of the database — and integrated close to a dozen external providers, each with its own protocol and data format.

Between 2025 and 2026 I worked independently: my own and client projects, architecture consulting, integrations and a fair amount of infrastructure, alongside teaching and mentoring.

Today

Since 2026 I am Head of Technology at Nextay (Alcúdia), part of the Can Calco Group. The job is no longer only writing code: I define the architecture, choose the stack, prioritise alongside the business and support the team technically.

On the technical side I am building Corey, a bedbank platform with a supplier extranet, a client extranet and an internal management intranet, together with the webservices and API integration layer that connect it to the rest of the industry. We have also delivered the NextayHub integration with the Greek market.

My day-to-day stack is PHP/Laravel — with Octane where performance matters — Java/Spring Boot, Vue 3 with Quasar on the frontend (React and Angular too, depending on the project), and MySQL, Redis, AWS, Docker and Terraform for data and infrastructure.

Engineering philosophy

  • The safest code is the code that does not exist. The simplest solution that works in production always wins.
  • Premature abstraction is technical debt with compound interest.
  • Well-designed systems are boring to operate. Boring is good.
  • Technical documentation is part of the system, not an afterthought.
  • Scalability starts at design time, not in reactive optimization.

Beyond code

I teach programming, architecture and software engineering, as well as mathematics from secondary school to early university courses. I mentor engineers looking to grow in backend and architecture, and take on consulting and selected projects when they are a good fit.
