Software that runs your business — built to scale from day one.
I'm Noel Muñoz, a CTO and full-stack engineer based in Valencia, Spain. I design and ship high-performance websites, web apps and ERPs on clean, hexagonal architecture — so your software keeps moving as fast as your business does.

// 01 — Services
One engineer. Four ways to grow your business.
Different problems need different software. Here's what each one solves.
-
“Our website looks fine, but it doesn't bring in clients.”
Turn traffic into pipeline.
A slow or generic site quietly loses you leads every day. I build pages that load in under a second, rank on Google and guide visitors to one clear action — with analytics that show what converts.
- Core Web Vitals in the green
- Technical SEO
- Conversion-led structure
- Editable CMS
-
“We need a product that works on day one and doesn't collapse at 10,000 users.”
Launch faster, scale without rewrites.
Most MVPs get rebuilt within a year because they were never designed to grow. I build typed, tested, cloud-native products on clean architecture, so new features ship in days and growth never forces a rewrite.
- Next.js
- Spring Boot / Python APIs
- Google Cloud
- CI/CD
- AI integrations
-
“Our team needs a tool that works offline and talks to our hardware.”
Software that works where the browser can't.
Warehouses, studios, clinics and production floors need tools that run locally, handle files and devices, and keep working when the connection drops. I build cross-platform desktop apps that sync securely with your cloud.
- Windows & macOS
- Offline-first
- Hardware & file integration
- Auto-updates
-
“Our operations run on spreadsheets and a legacy system nobody dares to touch.”
Stop paying people to copy data between systems.
Manual processes cost hours every week and hide errors until they become expensive. I model how your company really works, migrate legacy systems step by step without stopping operations, and automate the workflows in between.
- Domain-Driven Design
- Legacy migration
- Integrations & APIs
- Role-based workflows
- Dashboards

Multiplatform App Development
// 04 — FAQ
What clients usually ask before we start.
Straight answers on pricing, timelines and how I work.
What software development services do you offer?
I build four kinds of custom software: high-performance websites and landing pages, web apps, desktop apps, and ERPs with process automation. I handle the full cycle — architecture, development, cloud deployment and maintenance.
How much does a custom website, app or ERP cost?
It depends on scope, so I don’t use generic rates. After a free 30-minute discovery call I send a proposal with fixed scope, timeline and price, so you decide with all the facts and no hourly surprises.
How long does it take to go live?
A landing page is usually live within a few weeks. Web apps and ERPs ship in phases: the first useful version arrives early and the rest builds on it, so you see results without waiting months.
Do you work with clients outside Spain?
Yes. I'm based in Valencia, Spain, and work remotely with companies across Spain and abroad. Companies in the Valencia area can also meet in person when the project needs it.
Why an independent engineer instead of an agency?
You talk directly to the person who designs the architecture and writes the code, with CTO experience. No middlemen, no handoffs between teams, and technical decisions made so your software stays easy to change for years.
How do we start working together?
Message me on LinkedIn with your goal in two lines. I reply within 24 hours, we have a free discovery call and, if it's a fit, I send a fixed proposal.
// 05 — Let's build
Your next system shouldn't need a rewrite in a year.
Tell me what you're trying to achieve. Within 24 hours I'll reply with an honest first take: whether it's worth building, the approach I'd use, and whether I'm the right person for it. If I'm not, I'll tell you — and point you to someone who is.
