Services
Freelance software engineering, from idea to production
One senior engineer who scopes, designs, builds and runs it — no chain of handoffs.

What I can help with
Hard problems cross layers. I work across all of them.
Products and MVPs
From an idea to something people pay for.
- Scoping and architecture
- Full-stack MVP with payments
- Prototype to production
Backend and APIs
Services and integrations that hold up under real traffic.
- Payment, messaging and booking integrations
- New services in Go, Java or TypeScript
- Event-driven systems
Cloud and platform
Infrastructure and delivery your team can own.
- AWS with Terraform
- Kubernetes and GitOps
- CI/CD and safe deploys
Reliability
Observability, incident response and faster systems.
- Dashboards and alerts that matter
- SLOs and on-call
- Fixing slow or fragile systems
Security and identity
Authorization, sessions and access control done right.
- Authorization with Cedar, ABAC or RBAC
- OAuth/OIDC and sessions
- Fraud and device trust
AI agents and tooling
Agents and LLM features that do real work.
- Agent infrastructure and evaluation
- LLM features in existing products
- Internal tools and automations
Ways to work together
Project
A defined outcome: an MVP, a service, a migration.
- Fixed scope and price
- Weekly demos
- Everything is yours
Ongoing
Senior engineering capacity without a full-time hire.
- Days per month
- Platform and hard features
- Scale up or down
Advisory
A second opinion before a big decision.
- Architecture reviews
- Technical due diligence
- Written recommendations
How a project runs
Small steps, working software early, no surprises.
Intro call
30 minutes to understand the problem.
Proposal
Scope, approach, milestones and price, in writing.
Build
Weekly demos. Code and infra in your accounts from day one.
Launch
Monitoring, alerts and runbooks before real users arrive.
Run or hand over
Docs and handover — or I keep running it.
A good fit if…
- You need a technical partner to build the first version properly.
- Your team needs a senior engineer for a hard, cross-cutting problem.
- Your platform or reliability needs an owner.
Not a fit: brochure websites, WordPress themes, or ticket-only work.
Questions
Do you work remotely?
Yes, from Palma (CET), for clients anywhere. In Mallorca, happy to meet in person.
How much availability do you have?
I take a few projects at a time. We agree timing before we start.
Can you work with our existing code?
Yes. I start from what exists and change it step by step. Rewrites are rarely the answer.
Who owns the code?
You do. Code, infrastructure and docs live in your accounts from day one.
How do we start?
Book a 30-minute call or send a few lines by email.
