Projects
AppLinkers
Web platform built from scratch for university communities. Used by @linkers.madrid and @salseo_usc, with a combined reach of 200,000+ followers. Started as a social matching app with a vectorized compatibility algorithm (NumPy) and intelligent filters (exclusive, reciprocal, bonus), and has grown into a full university toolkit: apartment and room search with compatibility-based matching, permanent housing-compatibility test, per-community event management, and a nightlife ticketing vertical with event discovery and per-venue pages.
Relational data model with multi-tenancy and reusable question hierarchies with full match traceability. GDPR compliance with versioned consent, anonymization preserving referential integrity and automated rights (access, erasure, art. 22). Infrastructure with three independent environments (production / dev / local) with audit system on its own DB, encrypted automated backups and tooling to preserve critical data when copying between them. Email-based claims with auto-resolution tokens, address obfuscation and transactional templates. PWA with full dark mode, per-environment feature flags, matching-algorithm calibration system with synced sliders, live metrics refreshed every 8h on the dot and cron jobs for scheduled tasks. Housing module from scratch: filtered search with custom dropdowns, owner dashboard with stats, editor with gallery, Google Maps Geocoding, GTFS public-transport data integration with Haversine nearest-stop calculation, OAuth signup for owners and room request flow. Operations managed via custom CLI and TUI wrapper (OpenTUI + SolidJS) bridging Python subprocesses. Ticketing & attribution (2026): Fourvenues integration with nightly sync across 14 venues, SEO event pages per venue and geographic zone with JSON-LD, an RRPP attribution engine (personal tokens, 7-day last-click, anti-self-purchase, GDPR opt-in) and AI-generated event descriptions (Xiaomi MiMo API) with human review.
★ Selected as one of the 25 recognized initiatives (10 awarded + 15 with diploma) of the 23rd Edition of Actúa UPM, the entrepreneurship program of the Universidad Politécnica de Madrid.
Homelab
Self-hosted infrastructure on Proxmox VE with multiple VMs and LXC containers. Reverse proxy, monitoring stack (Grafana, Prometheus), Docker applications, and automated backup systems.
@aeropedrax
Free and open educational initiative for engineering students. YouTube channel with lecture-style videos and shared course notes. Strong engagement and lasting positive impact among students.
Parallel Processing
Research on GPU parallel computing strategies for matrix and vector operations. Benchmarking and performance tuning of scientific computations across multiple languages. The bachelor's thesis extended this with a novel PDE formulation using global Lagrange interpolation. Built so that any reader can reproduce every benchmark on their own machine with step-by-step instructions.
M2i
Unified digital platform for the inter-university MSc in Industrial Mathematics (M2i): materials, calendar, lecture recordings and Moodle from the 5-university consortium (UPM, UC3M, USC, UDC, UVigo) in a single interface. Django, multi-provider OAuth, integration with 4 separate Moodle instances with encrypted tokens, iCal feed, PWA and Cloudflare R2 for recordings.
GestorIA
Self-hosted tax and invoicing dashboard for Spanish freelancers: income, deductible expenses, VAT/IRPF and filings. Node + Express with SQLite (sql.js), LaTeX-generated invoices and contracts, PWA, running on a Proxmox LXC behind Tailscale with data-as-code deploys from git.
FitReader
Personal health analytics: Health Connect data (smart band + scale) through a Python ETL with 12 analyzers into a React + TypeScript dashboard: trends, correlations, training load and a health score over 650+ days of data.
