What I do for you
Individual or company, the need isn't the same. Choose your profile and I'll speak to you directly.
Your online presence, cut clean
Launching a business, a project, an idea? You deserve better than a tired template or a cousin who "knows a bit of code". I build your showcase site or your application on clean, fast and lasting foundations, designed to represent you and convert.
- Showcase site or landing page, fast, responsive and polished down to the last pixel, optimized for search and speed
- Small web app or custom tool when a site is no longer enough (booking, smart form, private area)
- Straight talk with no jargon: I tell you what you actually need, not what pads the bill
- Clean code that you keep: no lock-in, no hidden dependency on a provider
What I offer
Clear services, from a showcase site to expert engagements. Firm quote after scoping, never a surprise along the way.

How we hunt together
No black box. A readable method, from the first exchange through follow-up, so you always know where the hunt stands.
-
Scent
We frame the real need, the constraints and the budget. I ask the right questions before writing a single line: no silent assumptions, no phantom quote.
-
Track
I design the simplest architecture that holds: justified technical choices, security and quality built in from the start, clear milestones to follow progress.
-
Hunt
I develop in deliverable iterations, so you watch the product grow. Readable code, tested where it matters, green CI. No surprises on go-live day.
-
Guard
Go-live, handover and documentation. You keep control of your code. The pack stays reachable: follow-up, fixes and improvements as you need them.
The wolf behind the code
No client reviews yet, and I won't invent any for you. Instead, concrete and verifiable commitments. You judge on the evidence.
-
Code that you keep
No lock-in, no black box. The code is readable, documented, and it's yours: you take back control whenever you want.
-
Security by default
Server-side validation, access management, protected secrets. Security isn't an option you bolt on at the end.
-
Tested where it matters
Tests on critical business logic, regression covered after every significant bug. Quality is proven, not promised.
-
Truly delivered
A single definition of "done": it runs in production, it's documented, it's handed over. The rest is just talk.
The questions that bite
-
Why go with a freelancer rather than an IT services firm?
You talk directly to the person who writes the code. No middleman diluting the standard, no hidden margin on a junior sold to you as a senior. You pay for delivery, not for an organization.
-
How much does a project cost?
It depends on the scope, and that's normal. We frame it together in a free first exchange, then I hand you a clear, firm quote. No surprises along the way: if the scope shifts, we talk about it first.
-
Do you work remotely or on site?
Mainly remote, based in Tenerife (Canary Islands): Western European time zone, the same as Lisbon or London, so no awkward gap with the rest of Europe. Regular check-ins, occasional on-site visits possible. I work in French, English, Spanish and Russian.
-
Who owns the code once it's delivered?
You do, entirely. No hidden dependency on my services, no trap license. I document and hand over so that you (or your team) can take back control on your own.
-
You don't have client reviews yet, so why trust you?
Honestly: because I'm betting everything on it. I'm starting out independent after years of delivering for IT services firms. My method, my stack and my commitments are public and verifiable. And the first exchange costs nothing: you judge on the evidence.
-
How soon can you start?
Depending on my current hunting plan 🐺, we'll talk about it from the first contact. For urgent engagements, just say so and I'll make it work.
Join the pack
A project, a question, a doubt? The first exchange is free and with no strings attached. Describe your need and I'll get back to you fast.
