Professional
🛃 G-Nex / Anexo 24
▶
Multi-tenant customs management system for foreign-trade operations in Mexico (customs declarations, invoices, value statements, VUCEM integration), built as part of my work at G Global. One MySQL database per client company, resolved dynamically from the tenant_id carried in the JWT — no shared databases, no hardcoded routes.
- 3-service architecture: React + TypeScript, NestJS (auth), Express + TypeScript (API core)
- Background processing with worker threads for bulk imports/reports
- SOAP integration with government systems, PDF generation, S3 storage
🚨 Transportation platform — SITT ▶
Platform for the public transportation system, integrated with the C4 public-safety command centers. Built during my time at IDG (client name withheld for confidentiality).
- Panic-button feature integrated with the C4 system via SOAP Web Services
- JSON ↔ XML conversion to communicate with C4's SOAP services
- Endpoints for real-time data queries and submission
- Service integration between mobile apps and backend
Personal
🦝 NAKAMA
▶
Personal blog and creative studio covering game dev, backend, music, apparel and 3D printing: devlogs, tracks, reviews and experiments. Static site built with Eleventy, zero JavaScript for visitors; heavy media served from Cloudflare R2.
🎵 Velody
▶
Desktop app for splitting songs into stems (vocals, drums, bass, etc.) to practice along with. Three independent processes coordinated via IPC — audio separation happens outside the main process so the UI never freezes.
- Custom audio engine built on the Web Audio API, with precise sync between stems
- Audio separation with Demucs (PyTorch) and BPM/key detection with ML
- Automatic Python environment setup on first launch
💰 Varo
▶
Personal finance mobile app with smart savings-goal forecasting, automated recurring transactions via cron jobs, and AI receipt scanning (Groq Vision) for automatic expense capture. Native Android widget rendered with Skia.
📸 Vaulta
▶
Private-vault-style photo/video storage and organization app: facial recognition and person grouping (face-api + TensorFlow in an isolated process), duplicate detection via perceptual hashing, async ZIP export, vault protected with PIN + biometrics.
📚 Vellum
▶
Mobile EPUB reading app with progress sync, notes, and smart recommendations. Offline-first architecture with a persistent sync queue and automatic retries; AI-generated chapter summaries (Groq/Gemini).
🎮 Viva2026
▶
2D stealth-action game in development, inspired by Katana Zero, Hotline Miami, and Dead Cells. Level built entirely procedurally at runtime (no prefabs): camera, player, enemies, platforms, and UI all generated by code. Extensible mask-based ability system.
🎬 Veya
▶
Mobile app to discover, save, and organize movies, series, and anime — solves the "I wanted to watch something and now I can't remember what" problem. Unified search over TMDB and AniList, progress tracking (pending/watching/finished/dropped), and recommendations based on the user's actual taste.
🎨 arcd_kit
▶
Shared design system across all 6 product apps (Varo, VaultGaming, Vaulta, Vellum, Veya, Velody): one gray ramp, typography, spacing/radii, motion, and icons — with each app keeping its own brand color. Today it's a starter kit copied into each repo, with the plan to become an installable library via package.json. In progress.
🃏 PokeV
▶
Personal mobile app to keep my 6-year-old son's and my Pokémon card album: a collection with milestone-based achievements (never "how many are missing"), our own Pokédex showing only what we've discovered, AI-powered card scanning, and an Android home-screen widget that flips to a new favorite card. Personal, non-commercial project, not affiliated with Nintendo/The Pokémon Company.
