Full-stack developer at PiByte Labs. I build invoicing and fiscal systems, ERPs, e-commerce platforms, and marketing sites, end to end, from database to interface.
An open-source, type-safe data access layer for PostgreSQL: raw SQL typed by pgtyped, Zod-validated inputs, a typed query factory, and a CLI that runs the whole codegen pipeline. The data layer that powers Agates, ESPAU, Increscendo, and the Café Combate storefront.
Public site and clinical admin platform for a nonprofit autism organization: managing student records, therapy programs, and developmental assessments (DENVER model, ADOS-2) on a type-safe PostgreSQL backend with role-based access, two-factor auth, and encrypted records.
A 13-app ERP for a coffee roaster spanning warehouse and inventory, CFDI invoicing, sales, purchasing, and production planning, plus a full e-commerce storefront with Mercado Libre integration, with role-based access and offline-capable sync.
A full e-commerce store for collectible agates: rich multi-image product listings, role-based admin, cart and wishlist, Stripe/PayPal checkout, and ShipStation fulfillment, all on a custom type-safe data layer.
A corporate fiscal-management platform built as Express microservices: invoicing alongside customer, HR, and document-reception modules, with encrypted storage on Google Cloud.
A CFDI 4.0 electronic-invoicing platform: invoice creation, IVA/IEPS tax calculation, PDF generation, real-time cancellation tracking via HMAC-signed webhooks, billing reports with Excel export, and SAT massive CFDI downloads. Also deployed for the Sonolife client.

Site for an insurance and advisory firm: services, client testimonials, a Google-Maps location, and a contact form.
Brand site for a Mexican cereal maker with 70+ years of history: a Google-Maps store locator with nearest-branch search, a blog, and product/flavor showcases.
Portfolio site and album-management backend for a wedding photographer: authenticated admin, album and gallery browsing, and large-scale photo uploads to Backblaze B2.
Marketing site and admin platform for an events company: a quote generator with PDF export, a rich-text blog, client testimonials, and authenticated management of products, clients, and event types.
Bilingual website for an architecture firm: services and project detail pages, with a validated, spam-protected contact form wired to transactional email.
Portfolio for an event and wedding photographer: masonry galleries organized by event type, with per-event detail pages served from a lightweight gallery API.
Dual-brand site for a holding company (La Vaquita and Displach): catalog browsing for animal and agricultural products with data synced from Google Sheets/Drive, plus a branch locator.
An open-source real-time collaborative Kanban board: live multi-user boards with drag-and-drop, custom authentication, and persistent storage.
