AluminioLogo — Retail ERP, POS & Fiscal Invoicing

I built AluminioLogo's ERP and point-of-sale system from the ground up for a hardware and aluminum distributor with several branches in Venezuela. It covers branch inventory, quotes, returns, receivables, roles and permissions, and a POS that takes payments in USD and bolivares with exchange rates. The part I'm proudest of is fiscal invoicing: a small agent runs as a Windows service in each store and prints invoices, credit notes and daily reports on certified fiscal printers. There is also an admin web app, a mobile app and a product catalog. It has been live in production since October 2026, with more than 3,000 commits. I work with Claude Code daily: I make the architecture decisions and the AI helps me move faster.

Background Action! — Casting Platform for iOS, Android & Web

Background Action! is a casting platform I built for a Mexican film and TV extras-casting company, rebuilding an older system with a large base of talent profiles. One Expo codebase delivers iOS, Android and web: an eight-step registration wizard with a live casting ID card, photo books, a skills catalog, legacy-profile import and Premium subscriptions. Payments use Stripe on the web and native in-app purchases on mobile. I added push notifications and versioned legal acceptance, and co-built the Laravel 13 API. The first working version took about a month, with automated tests and release runbooks. I used Claude Code throughout, directing the architecture myself.

Legal Global Consulting — Client App on iOS, Android & Web

Legal Global Consulting manages rental protections and legal guarantees for clients in Mexico, and I have built its client product since the beginning. First came the React web front end, then the original React Native app on the App Store and Google Play, and most recently a full rebuild on Expo SDK 57 that ships as an in-place update to the same store listings. The new app also runs on the web from one codebase. Clients calculate and contract protections, follow their policies, book appointments, report breaches, pay with Stripe or PayPal and get push notifications. I also contribute to the Laravel API. A large Jest suite kept the migration low risk.

Wawa Rider App — SRSE Trip Planner, Wallet & Smart Boarding

Wawa is a Venezuelan mobility company running bus circuits, private transport and rentals in Venezuela, Colombia and Guatemala, and I have been the top contributor to its rider app since 2024. My biggest feature there is SRSE, the Smart Request Schedule Engine I designed and built end to end. Riders type where they are going and see every departure of the day as walking plus bus itineraries, with up to one transfer, filtered by real seat availability and ranked by arrival time, transfers and walking. Booking is atomic across legs: a trip gets all its seats or none, and if something breaks the app says which leg failed and offers new options. The engine is pure TypeScript in a hexagonal design with about 660 test cases, load-tested with k6. Around it, the app handles wallet top-ups with several payment providers, favorites, automatic boarding, QR boarding tickets and push notifications, shipped with EAS and over-the-air updates.

RED1A1 V2 — Real-Estate Marketplace on Web, iOS & Android

I led the rebuild of RED1A1, a Mexican real-estate marketplace and professional network, across web, mobile and API. The new Next.js 16 site has a map-first home, directories, owner and admin dashboards, white-label agent websites and Stripe checkout. I shipped a new Expo app as an in-place update to the existing App Store and Google Play listings, with realtime chat, push notifications, native in-app purchases and over-the-air updates. On the Node and MongoDB backend I added realtime delivery, membership logic and scheduled jobs. Strict TypeScript, Zod validation and a 70-flow Maestro suite on Android keep it steady. This extends my earlier work on RED1A1's template pages.

Julio Toledo Perfil IOS / ANDROID

JulioToledo Perfil is a mobile project designed to make life easier for people who want to participate in castings for this film and series production company in Mexico. Although it is still under development, it’s shaping up to be one of my best projects due to the scalable and maintainable structure I am implementing with TypeScript and pure React Native to deliver a high-quality product.

LGC Web / IOS / Android

This is a hybrid project developed with pure React Native, dedicated to clients who subscribed to protections within the LGC system (which you can also see in my portfolio). The app allowed users to manage their protections, renew them, file claims, purchase additional protections, contact the company, and chat with an AI assistant. It was my first app fully developed from scratch and launched for both Google Play Store (Android) and App Store (iOS). It’s worth noting that most of the backend wasn’t developed by me, but I did work on several key functionalities, such as the integration of payment gateways, the push notification system for all three platforms (Web, Android, and iOS), the AI chat, and more.

EK Despacho

Ek Despacho was an operations app developed for internal use within the EK motorcycle factory. The app was built in several phases, starting with a basic version that gradually expanded to handle more operations within the plant. The system went through about three updates, but its core and primary functionality was to scan barcodes and QR codes on specific strategic items used in operations to log transfers or dispatches of motorcycles or parts.

Sutil App

Sutil is a freelance project that was presented to me in December 2023, which due to the short duration of the client's interest in developing it, left me with a lot of knowledge and I really liked doing what I managed to do, in the first instance I wanted to make an app Live Streamings, in which they could be monetized so that users can see lives of other users and leave their money with mini-purchases within the app, a project that could have been something very good, but due to poor administration and lack of interest never came to light. What was developed was the backend functionality that allowed authenticating users and authenticating video calls, with specific authentication tokens for them, and the entire frontend developed in React Native!
