What I doWhat I do

Three core services for startups that need to move fast, scale smart, and build the right team.

$ diego hire

I send you 3 candidates who can start Monday. Pre-vetted for technical depth and startup fit.

Read the playbook→

$ diego build

Build Your MVP

Working product in weeks, not months. Clean code, solid architecture, features that validate assumptions.

Read the playbook→

$ diego lead

Lead Your Team

Interim CTO who writes code. I make architecture calls, unblock engineers, and ship alongside them.

How I workHow I work

I ship code, find engineers, and make technical calls. No decks. No ceremonies.

  1. 30 min

    Call

    You tell me what's broken. Hiring pipeline empty? MVP stuck? No one to make architecture decisions? I ask questions until I understand the real blocker.

    → Scope and price

  2. Day 1

    Start

    I get access to your repo, Slack, and whatever else I need. No onboarding docs, no 2-week ramp. I read the code and start working.

    → First commit or first candidate

  3. Weekly

    Ship

    Every week you get something: a deployed feature, vetted candidates, a technical decision documented. If I'm stuck, you hear about it same day.

    → Working software or filled roles

  4. When it's done

    Done

    The engagement ends when the work is finished. No trailing retainers, no manufactured dependencies. You keep everything I built.

    → Code, docs, and ownership

FAQFAQ(08)

Questions founders ask me most. If yours isn't here, let's talk.

[+][-]Can you really build an MVP in 7 days?

Yes. I focus on core features that prove your concept. No bloat, no unnecessary integrations. You get a working product that real users can test.

[+][-]What if I need changes after launch?

Two weeks of bug fixes are included. For new features or major changes, we can discuss ongoing support or a Phase 2 project.

[+][-]What tech stack do you use?

Next.js, React, TypeScript for frontend. Supabase or Neon for database. Vercel for hosting. Modern, battle-tested tools that scale.

[+][-]Do you work with non-technical founders?

Absolutely. I translate technical jargon into plain English. You'll understand every decision and why it matters for your business.

[+][-]What's your timezone and availability?

Based in Europe (CET/CEST). I work with US and UK founders regularly. Daily updates via Slack or your preferred channel.

[+][-]What if I only have a rough idea?

Perfect. Day 1 is all about refining your vision into concrete features. I'll help you prioritize what matters for your MVP.

[+][-]Can you integrate with existing systems?

Yes. APIs, databases, payment processors: if it has an API or SDK, I can integrate it. We'll discuss specifics during discovery.

[+][-]What happens to the code?

You own everything. Full source code, documentation, and deployment access. No vendor lock-in, no recurring fees to me.
