Peer2Stream
A web app for discovering, watching and organising films and series with TMDB data. It was my DAW final project, graded 10/10, and I built it with Ismael Delgado. Next.js 15, React 19 and MongoDB.
About me
I'm Alejandro Cabrera, a web and backend developer in Granollers. I build websites, automations and custom software for small and medium businesses across Catalonia, through Digital DesAny, the studio I run with Oriol Tamborero.
I use Go and Fiber, Java 21 and Spring Boot 3, Next.js, React and TypeScript, WordPress and PHP, PostgreSQL, Redis and Docker.
My path: from the family laptop to Digital DesAny
Hardware
2011-2016
- 2011
I swap the family laptop's hard drive.
Granollers, aged 11
The family laptop broke. Instead of throwing it out, I opened it up and swapped the drive. That's how I found a whole system behind the screen that I could read.
- 2012
I install Mandriva to play Wormux and Battle for Wesnoth.
First Linux
Gaming was the driver. On that laptop I fought with packages, repositories and the terminal.
- 2014
I build my first PC with what I earn fixing computers.
For neighbours, family and friends
I started fixing computers for people around me: small repairs, reinstalls and setups.
- 2016
I start replacing components: RAM, GPU, cooling.
Small business and individuals
The repair work grows. On top of reinstalls and setups, I replace hardware: RAM, graphics cards and cooling systems.
- 2011
Support and study
2019-2022
- 2019
I start teaching myself to code on helpdesk shifts.
Vaccination centre, first formal job
On-site tech support: tickets, diagnosis and escalation. In the quiet hours I also prepare for the entrance exams to a higher vocational course.
- 2022
I start the DAW higher vocational course.
Web Application Development
From learning alone on shift to learning with structure and classmates: Java (OOP), MySQL, HTML, CSS, JavaScript, Angular, React, PHP and Laravel.
- 2019
Web and backend
2024-2026
- 2024
I help integrate WiPay with vending machines at Automated Transactions.
Payments over a serial bus at 9600 baud
The cashless payment connects to the machine over MDB. The actual work: translating payment payloads to hexadecimal over a serial bus at 9600 baud.
- 2025
I join VMV Cosmetic Group as lead web developer.
Barcelona, 2025-2026
Within months I was already writing Go microservices, integrating the AS/400 from Java and building the first internal WAF.
Everything I looked after at VMV - 2026
I co-found Digital DesAny with Oriol Tamborero.
Granollers
A web studio for small and medium businesses across Catalonia: custom websites, social media, automations and custom software.

Education and open source
Pokédex DS
A DAW exercise: a Pokédex shaped like a Nintendo DS Lite, with live data from the PokeAPI. The DS shell is adapted from a CodePen by Anton Essential (MIT licence).
Simply Bootstrap Carousel
On WordPress.org I've published the Simply Bootstrap Carousel plugin, which has over 10 active installs.
How I work
The API and the data first
Before writing business logic, I design the API contract and the database schema. Both are documented, the API in versioned OpenAPI.
I measure before changing things
Structured logs and metrics from day one, and I read the logs before touching anything. In the Neibr stress test, p95 stayed under 100 ms at about 968 requests per second.
I plan for failure
Timeouts, retries and rate limits from the start, and I validate external data before processing it. In Neibr, idempotent writes and HMAC-signed webhooks.
Docs next to the code
Short ADRs for the decisions that matter and READMEs you can actually run. Digital DesAny projects are delivered with full technical documentation.
