Neibr
Co-founder · shut down in 2026B2B API for parcel carriers.
When a delivery fails, the parcel goes to a neighbour within 200 m instead of going back to the depot.
I was a co-founder and the only backend developer. I also set up the deployment and the website, and took part in sales and the company's social media.
Go (Fiber), PostgreSQL and Redis. Assignment prefilters by bounding box in SQL, then computes the exact distance with Haversine. Multi-tenant API keys, idempotent writes, HMAC-signed webhooks and an immutable audit ledger.
- Award
- One of the winning projects of the Santander X Spain Awards 2026 (UVic).
- Why it closed
- Talking to a large carrier showed us problems in the model that code wasn't going to fix, so we shut it down before launch.

GOK Thermal
Freelance jobWebsite for an HVAC installer in Granollers, with a project gallery, reviews and direct contact by WhatsApp or phone. I built it as my own freelance job, outside Digital DesAny.
Path
Fifteen years learning to hold systems up.
From swapping the family laptop's hard drive to starting my own studio. This is the short version.
- 2011
I swap the family laptop's hard drive.
The family laptop broke and, instead of throwing it out, I opened it, swapped the drive and found a whole readable system behind the screen. Everything started that afternoon.
- 2012
I install Mandriva to play Wormux and Battle for Wesnoth.
Gaming was the driver. I installed Mandriva on that laptop and fought with packages, repositories and the terminal. I learned more in a week trying to launch Wormux than in a year of school.
- 2014
I build my first PC after doing freelance helpdesk work.
I started fixing computers for people around me: small repairs, reinstalls and setups. That paid for my first PC.
- 2016
I start replacing components: RAM, GPU, cooling.
The repair work grows. On top of reinstalls and setups, I replace hardware: RAM, graphics cards and cooling systems.
- 2019
On-site helpdesk at a vaccination centre.
On-site tech support: tickets, diagnosis and escalation. In the quiet hours on shift I start teaching myself to code and prepare the entrance exams for a higher vocational course.
- 2022
I start the DAW higher vocational course.
Java (OOP), MySQL, HTML, CSS, JavaScript, Angular, React, PHP and Laravel. From learning alone on shift to learning with structure and classmates.

I help integrate WiPay with vending machines at Automated Transactions.

Lead web developer at VMV Cosmetic Group.
I joined as lead web developer. Within months I was writing Go microservices, integrating the AS/400 from Java and building the first internal WAF.
- 2026
I co-found Digital DesAny with Oriol Tamborero.
A web studio for small and medium businesses across Catalonia: custom websites, social media, automations and custom software.
Education
Origins.
DAW projects that set the direction. Public code on GitHub, with what went right and the traces of learning.
On WordPress.org I publish the Simply Bootstrap Carousel plugin, with over 10 active installs.
Principles
Four principles. Zero gimmicks.
What I apply to every system I touch. It works for a B2B API, a legacy integration or the portfolio you're reading.
API design comes first.
Before writing business logic, I design the contract and the database schema. The shape of the data predicts the shape of the product. Versioned OpenAPI and a documented schema before the first function.
I measure what moves.
Structured logs and metrics from day one. I read the logs before changing anything: without data, optimising is guessing. Every service exposes enough to tell whether it's alive and how long things take.
I build for failure.
Timeouts, retries and rate limits from the start. The happy path is the minority; I design so failures stay contained. I validate external data before processing it, not after.
Docs as code.
Short ADRs for the decisions that matter, READMEs you can actually run and version control for everything. Docs live in the same repo as the code, not in a wiki nobody visits.
