Software engineering studio

Custom software.We build itwith you.

We're a small studio with more than 15 years building software. We develop web apps, mobile apps, AI solutions and small games for small businesses and product teams. We work with you from start to finish, shipping every two weeks, and you always talk to the person writing the code.

01Services

What we do, and what we don't.

We only list what we can stand behind, and we organise it by the problem it solves rather than by the technology. If your project doesn't fit here, we'll tell you and save you the meeting.

  • 01

    Your operation doesn't fit an off-the-shelf product.

    Custom Software

    We build the software your business needs when no standard tool matches the way you actually work.

    • Bespoke applications
    • SaaS platforms

  • 02

    Your customers need you on their phone, not in a browser.

    Mobile Apps

    Native and cross-platform apps, built with whatever fits your product and your team best.

02Work

Don't take our word for it: try it.

Everything we show is in production and can be opened right now. The ones marked as our own product are exactly that: nobody commissioned them, which is why we can show the inside of work a client wouldn't always let us describe.

And 7 more: Plazoleta, Isobaria, FlupCode, OpenGit, aemet-mcp, Flapo, Ahorcade.

You can open and check every bit of this. Shall we talk about yours?

03Technologies

The problem first. The technology second.

We choose the stack that best fits your product, your team and your timeframes. Never the other way round.

04How we work

From idea to production, without waiting until the end.

We build and ship from the start, with progress every two weeks. And we carry on after launch.

  1. 01

    Discovery

    We look at the business problem before the technical solution. We come out with scope, risks and an estimate you can rely on.

  2. 02

    Design

    Architecture and UX in parallel. We define how it will be built and how it will be used, and validate that before writing code.

  3. 03

    Development

    Short iterations with continuous delivery. You see working software every two weeks, not progress reports.

  4. 04

    Launch

    Going live with automated deployment, observability and a contingency plan from day one.

  5. 05

    Evolution

    Support and ongoing development. The product keeps growing with your business instead of ageing.

05Why us

Being small isn't a limitation, it's the advantage.

We don't compete on size or on catalogue. We compete on you working directly with people who know the craft — and on being able to check that from the first call.

  • You talk to whoever builds it

    No account managers, no rotating juniors. The person listening to you is the one writing the code.

  • New company, old craft

    More than fifteen years each building software in production. The studio is young; we aren't.

  • Few projects at a time

    That's why we can properly get into yours. If we're not a fit, or we can't make it, we say so before starting.

  • We hand over, we don't lock you in

    Code, infrastructure and documentation your team can maintain without us. Staying is up to you.

  • Accessibility, performance and security as standard

    Requirements from the first commit, not a phase that gets cut when deadlines bite.

No middlemen and no rotating juniors: you talk to whoever builds it.

06Team

The people you'll be talking to.

No account managers in between. Whoever listens to you on the first call is the one who'll write the code, and their track record can be checked.

Software engineer and founder

More than 15 years building software. I work across product, architecture and code, helping turn ideas into digital products that actually work. At Plazoleta I'd rather work directly with whoever has the problem and build the solution together.
