Websites, apps and automations
I'm Judit, a software engineer. I design and build digital products for businesses that want to stop fighting with technology: websites that look good and convert, apps people actually use, and automations that give you hours back.
Fixed price
A clear quote before we start. No surprises halfway through.
Talk to me directly
No account managers. I do the design and I write the code.
You own the code
Domain, repository and every access handed over. No lock-in.
// Services
What I can build for you.
From a simple website that genuinely works to full platforms with users, payments and an admin panel.
Custom websites
Your site built from scratch, fast and designed so visitors end up contacting you.
- Landing and company sites
- Local SEO so people find you
- Forms and bookings
- Legal pages and GDPR
Mobile & web apps
Applications used day to day, on the phone and on the desktop.
- Installable apps (PWA)
- Client or patient portals
- Internal business tools
- Works offline
Automations
If you do it by hand and it repeats every week, it can probably be automated.
- Lead generation
- Telegram and WhatsApp bots
- Connecting your tools together
- Automated AI reports
Custom platforms
Products with users, a database and a control panel, built around how you actually work.
- Sign-up and login
- Search with real filters
- Admin dashboard
- Multi-language and payments
Blockchain & Web3
My technical specialty: smart contracts and decentralised applications.
- Smart contracts in Solidity and Rust
- Security audits
- dApps and wallet integration
- Tokens and NFTs
Maintenance & improvements
You already have a site or app and want someone to look after it and grow it.
- Updates and security
- Speed improvements
- New features
- Support when you need it
// Work
Things I've delivered.
Real client projects and products of my own. For privacy I show the sector and what was built, not the names.
Website with a free first session
A complete site for a licensed psychologist: warm introduction, services, and a form that turns visits into first consultations. Optimised to show up in local searches.
Website and patient portal
An online presence for a nutritionist plus a private area where each patient finds their plan, their progress and their resources, including gluten-free material.
Clinic management app
An app for the daily run of a clinic: patient records, sessions, prescribed exercises and assessment forms, all from the phone.
Basketball transfer portal
A platform connecting players, coaches and clubs through verified profiles and a search with real filters, replacing WhatsApp groups and personal contacts. Bilingual Catalan/Spanish.
Household task organiser
An app to split housework between family or flatmates: what needs doing, how long it takes and whose turn it is. Nothing to install and data stays on your device.
Lead-finding system
A system that sweeps businesses in an area, spots which have no website or an outdated one, then scores and verifies them automatically. Turns hours of manual research into a list ready to contact.
// Process
Simple, with no surprises.
From the first message to a working project, without jargon and with progress you can actually see.
We talk
A free call to understand what you need and whether I can help. No commitment.
I send a proposal
What's included, what it costs and when it'll be ready. Fixed price before we start.
I build it
I work in phases and show you progress every week, so you can weigh in as we go.
We launch
I publish the project, show you how to run it and hand over every access.
I stick around
Still available for improvements, questions and whatever comes up.
Got something in mind?
Tell me what you need, even if it's still fuzzy. I'll come back with an honest proposal: if I think you don't need it, I'll say so.
