What I do

How I can help

Most people come to me for one of two things — building a product, or a website, new or modernized. Each has its own page with the full detail.

About

A senior engineer you can hand the whole problem to

I’m a senior software engineer who designs and builds the things you sell with: landing pages, marketing sites, web apps and native mobile apps. In practice I cover the whole spectrum — new builds, refining and rescuing existing ones, and independent audits.

My priority is simple: ship software that works, that’s maintainable, and that actually moves your business forward. You get clear communication, pragmatic decisions, and ownership from first call to production.

  • End-to-end ownership — design, code, deployment
  • Clear communication and realistic timelines
  • Pragmatic, maintainable, well-tested solutions
  • Comfortable jumping into existing codebases
FAQ

Questions, answered

How much does a project cost?

It depends on scope. Landing pages and marketing sites are fixed-price; larger web and native apps are quoted after a short discovery call. You always get a clear price before we start — never an open-ended hourly bill.

How long does it take?

A landing page is typically 1–2 weeks, a marketing site 2–4. Web and native apps depend on scope, but I work in short iterations so you see real progress every week.

Do you work remotely?

Yes — I work remotely with clients anywhere, async-friendly, with regular check-ins. I’m based in Barcelona (CET).

Can you take over an existing project?

Absolutely. I regularly jump into existing codebases to refine, fix or rescue stalled projects — an audit is often the best first step.

What if I just need an audit?

That’s a service on its own. You get an independent review of code, security, performance and architecture, delivered as a prioritized, actionable report.

Are you available right now?

I take on a limited number of projects at a time. Send a message and I’ll tell you my earliest start date within one business day.
