Software · AI · Technical Leadership

Senior engineeringfor the software and AIyour business depends on.

DILAGO is a boutique engineering firm. We build production software, put AI to work where it pays, and advise on the technical decisions in between. Senior engineers working inside your repository—no account layers, no hype, and everything we build is yours.

Founded and led by Juan José López Martínez · Senior Software & AI Engineer.

01 · THE PRODUCTION GAP

Building got fast. Production didn’t.

AI tools can produce a working demo in an afternoon. What still takes experience is everything after: edge cases, data that stays consistent across systems, security your customers will audit, and AI that is measured instead of assumed.

  1. 01

    Demos meet reality

    Messy documents, concurrent users, network failures, and real permissions—this is where quick prototypes break.

  2. 02

    Silent failures between systems

    When integrations between billing, CRM, and ERP are not built to retry safely, orders disappear and someone reconciles spreadsheets by hand.

  3. 03

    Debt that compounds

    Rushed code—now generated faster than anyone reviews it—turns every new feature into weeks of firefighting.

02 · PRACTICE AREAS

Three practice areas. One firm accountable for all of it.

03 · HOW WE WORK

No black-box retainers. Every decision and every line of code is built to stay clear and useful inside your own infrastructure.

  1. Direct Senior Execution

    Senior engineers do the work, from the first call to the last pull request, led by founder Juan José López Martínez. Nothing gets lost between sales reps and junior developers.

    • No Intermediaries
    • Hands-On
    • Accountable
  2. Yours From Day One

    We work inside your repositories and your cloud accounts. Every line of code, credential, and decision record belongs to your company.

    • 100% Client IP
    • No Lock-In
    • Clean Handover
  3. Pragmatism Over Hype

    If a proven tool or a simple query solves the problem better than custom software or AI, that is what we recommend.

    • Build vs. Buy
    • Clear Scoping
    • Boring Tech Where It Counts
  4. Async and Written Down

    Momentum without filling your calendar: written decisions, clear pull requests, and short video walkthroughs.

    • Written Decisions
    • Clear PRs
    • Fewer Meetings

04 · START A CONVERSATION

Tell us what you’re building, fixing, or deciding.

Book a 30-minute call or send a short note. We take on a limited number of engagements at a time, so every client gets senior attention from the first conversation.

How an Engagement Starts

  1. 01

    A 30-Minute Call

    Your system, your bottleneck, or your idea. A technical conversation, not a sales pitch—under mutual NDA if you need it.

  2. 02

    A Clearly Scoped First Step

    An audit, a feasibility test, or a written plan. Scope and price are agreed before work starts and depend on your case, so you can judge the work before committing to more.

  3. 03

    Building Inside Your Repository

    Weekly progress, reviewed pull requests, and documentation, so your team stays in control.

A Good Fit If

  • Your software or AI workflows are critical to your operations or revenue.
  • You want direct access to the senior engineers who design and build the system.
  • You value ownership and clear trade-offs over flashy demos.

Probably Not a Fit If

  • You need a marketing site or a standard online store—a design agency or a template will serve you better.
  • You are looking for the cheapest hands to fill seats.
  • You want AI for the sake of saying you use AI.

Schedule a 30-minute call

Talk through your product, system, or technical decision with a senior DILAGO engineer.

  • 30-minute video call with a senior DILAGO engineer
  • Technical feedback, no sales pressure
  • Mutual NDA available before reviewing private code
