Projects from the present to the past.

  1. Live · Apr 2026 – Present

    LifeOS

    Web application built to monitor, plan, and manage users' time and money. Closed alpha. Deployed on a self-hosted server with an active domain as of today.

    • FastAPI
    • PostgreSQL
    • Docker
    • Cloudflare Tunnel
    • AI (co-dev)
    Read more

    What did I do?

    • Categorised activity tracking and planning: what is done, how long, and in which area of life.
    • Monetary tracking and planning: income, expenses, and personal financial projection.
    • Integrated honeypot for the homelab: passive detection of unauthorised access attempts.
    • Long-term goal: large-scale personal data collection to train specialised AI agents covering nutrition, time management, finances, and personal training. Theoretical framework under active hypothesis testing.
    • Multiplatform stack with three environments (dev / prod-staging / prod) over the same Docker Compose, separated only by `.env`.
    • Production-grade security: bcrypt cost 12, TOTP encrypted at rest, CSP, rate limiting, OWASP headers, Cloudflare Tunnel.

    Why did I make this project?

    • To learn backend development with Python.
    • To learn how to deploy on a self-hosted server.
    • To manage my time and money better.

    Venture

    JavaScript and WebGL2 client with an authoritative Node.js server for an isometric (2.5D) online multiplayer RPG. Renderer and shaders written directly on WebGL2.

    • WebGL2
    • GLSL ES 3.0
    • JavaScript
    • Node.js
    • Express
    • Socket.IO
    • Web Audio API
    • Blender
    • Python
    • AI (co-dev)
    Read more

    What did I do?

    • 3-layer renderer in WebGL2 / GLSL ES 3.0. Sprites in TEXTURE_2D_ARRAY (colour, normal, mask) with per-fragment Blinn-Phong, up to 16 concurrent lights in a std140 UBO with viewport culling and prioritisation. Instanced rendering: 1 draw call per texture batch.
    • Effects pipeline: 4000-particle pool with CPU simulation and instanced rendering, decals, outlines, glow pass (threshold + Kawase blur), ray-AABB shadow map over occluder volumes.
    • 2D spatial audio over Web Audio API: stereo panning and distance attenuation integrated into the game loop.
    • Authoritative server at 20 Hz with ECS architecture: entities as data-component containers, decoupled systems (Movement, Combat, AI, Pathfinding, Loot, Death, EntityState).
    • Command pattern for player actions: 14 commands validated per tick with a circular log for auditing. Observer (EventBus) for inter-system communication.
    • Network layer: chunk-based spatial grid with O(k) queries, room broadcast, per-socket snapshots, and delta compression — only changed fields sent per tick.
    • Live paper doll: equipment slots swappable at runtime without reload, with per-mask-zone colour profiles.
    • Custom content editor for weapons, armour, monsters, statics, attack areas, abilities, and colour profiles. 100% data-driven content (JSON). Pre-render pipeline in Blender with Python to generate the 3-layer sprites.

    Why did I make this project?

    • To learn Node.js on the backend.
    • Because I love video games.
    • Because during my studies we saw very few applications using sockets.

  3. Internship · Jun 2025 – Aug 2025

    CodeArts

    First formal professional experience: internship at a consultancy, contributing to a web product (showcase and ticket sales) for one of their clients. Symfony, Angular, PostgreSQL, Docker. Remote team, code reviews on PR.

    • Symfony
    • Angular
    • PostgreSQL
    • Docker
    Read more

    What did I do?

    • Real image sanitisation: upload API passing a 9-payload embedded test. Self-hosted with full responsibility, no third-party services.
    • JWT, httpOnly cookies, and server sessions: the grown-up version of the hand-rolled session system from Platos en ruta.
    • Refactor of the existing API and ER, SOLID class refactor, UI redesign with foundations for a style guide. Contribution accepted by the team.
    • Learned to use GitHub properly, and discovered first-hand the difficulties of taking over an in-progress project and working from scratch with a new team.

    Why did I make this project?

    • To learn Angular.
    • To consolidate my PHP knowledge.
    • To earn the degree.

  4. End of module · Feb 2025 – Apr 2025

    Platos en ruta

    End-of-studies project: two PHP monoliths for food delivery businesses. One handles online sales for the customer; the other lets the restaurant receive and manage orders. No framework.

    • PHP
    • JavaScript
    • Apache
    • CSS
    Read more

    What did I do?

    • Online storefront: menu catalogue, cart, and full order flow for the end customer.
    • Order manager with status tracker: the restaurant receives, accepts, prepares, and closes orders in real time.
    • Menu manager: create, edit, and remove products with photo upload from the management panel.
    • Two communicating monoliths: PlatosEnRuta (customer) and PlatosEnGestion (manager) on separate VirtualHosts, with an authenticated cross-domain endpoint for image uploads.
    • Native PHP and JavaScript, no framework. Custom session system: 64-hex opaque token, double expiry, strict CSP with nonces, hand-rolled CSRF.
    • Documented technical debt: 7 known issues explicitly named in code. No makeup.
    • UI and UX neglected: the project was focused on the backend.

    Why did I make this project?

    • To build a frontend and a backend without frameworks, recreating from scratch the tools that any library gives you out of the box: login, tokenisation, cross-domain API communication.

About

My passion for technology started very early: in '99 I got my first PC, and by the 2000s I was already tinkering with RPG Maker. Years later, in high school, came C++. Always hungry for knowledge and full of curiosity, by my teens I had already programmed in PHP and JavaScript.

Although my professional life has not been connected to new technologies, they have always been very present in my day-to-day. I was raised on Windows, but I started using Linux drawn by the world of cybersecurity — especially Red Team.

In 2023, after completing a cybersecurity course at INCIBE, I decided to commit fully: I enrolled and graduated in web application development.

Since then I have worked with diverse stacks: native PHP and Symfony, Node and JavaScript, Python and FastAPI, WebGL2 and GLSL. A love for databases: MySQL, Oracle, PostgreSQL. Engaged with the use of Artificial Intelligence, adapting to the new markets.

My most ambitious personal projects —LifeOS, Venture and this portfolio— I build by directing AI as a co-developer. My hand-written codebase comes from my internship at CodeArts (Symfony / Angular) and my final module project Platos en ruta (native PHP).

Although my preference is the back end, during my internship I worked as full stack, and after finishing some projects I am increasingly drawn to software architecture.

The background may look scattered —audio, electrical engineering, web development— but what changes between projects is the tools.

What does not change is the discipline.
