Things I've shipped

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.

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.

Regulariza tu Inmueble was a challenging project in many ways, mainly because it was also developed under pressure, but it was successfully completed. This project integrated a scheduling system for appointments between different users — clients, lawyers, and administrators. Clients were attended by lawyers after paying for their appointments through three payment methods: credit card, PayPal, and OXXO. It included the same payment functionalities as "Magno Evento Inmobiliario" (which you can also see in my portfolio). This project had a distinctive feature: it allowed users to schedule video calls through the Zoom SDK, which I integrated directly into the platform. Once the client logged in, they could easily set up a video call. The project was quite dynamic, as it had a robust security structure. It included real-time chats, notifications, emails, payment gateways to handle various microtransactions within the system, and many other features. It was one of my best contributions.

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 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 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!

I collaborated on a project for over 1 year and 3 months, in which I learned a lot about technologies such as AWS, GraphQL and WebSockets. Due to certain policies, I cannot give many details, but it is an online English school with the best teachers in the Dominican Republic, highly recommended. The project is in production and some of the functionalities I developed were a file explorer with drag and drop, a complete landing page, chat functionalities and WebSockets, among others.

I collaborated on a project called Chat App Ralph, which was a small open chat. The chat allowed to save a user through login to be used within the chat and send messages under that name. The chat is real-time and is built with WebSockets, Node.js and MongoDB. It was one of the projects in which the design was totally mine and it is also responsive, since the task instructions said that it needed to have a nice and responsive design, and this project was made as a technical test for work in Branak.
