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
🎵 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.
