Back-Office ERP for a Rental-Guarantee Company (Payroll & HR)

I built an internal back office for a Mexican rental-guarantee company, replacing spreadsheets and an older PHP system. The React and Laravel app brings branch expenses, income analysis, budgets, payroll, attendance, vacations and employee contracts into one role-based dashboard. I implemented the biweekly payroll engine with automatic period rollover, versioned recalculations and bonus tiers, vacation balances that follow Mexican labor law, contract expiry alerts, and an executive dashboard with scheduled Excel reports. I worked end to end, from the data model and cron jobs to the Material UI screens, over about ten months, through Internet 360.

Realtor Landing Page with NestJS to Zoho CRM Lead Pipeline

A bilingual landing page I built for a Tampa Bay realtor who serves the Hispanic community, with a small NestJS backend that sends every contact form submission into Zoho CRM. The React site uses Material UI and i18next for Spanish and English, validated forms and Meta Pixel tracking for ad campaigns. The API refreshes Zoho OAuth tokens on its own and exposes a single contact endpoint, so leads reach the client's CRM without any manual work.

Flip X — Real-Estate Investor Site with ROI Calculator & CRM

I built the corporate website for Flip X, a Florida fix-and-flip real-estate company that attracts investors, working through the DotDev agency. The bilingual React and TypeScript site covers services, the team story, projects with before-and-after views and testimonials, with a hero video and animated sections. I added an Invest page with a property inventory and an ROI calculator, and a validated contact form that creates contacts directly in the client's Zoho CRM. It is fully available in English and Spanish and deployed on Vercel.

Golden Flower Retreats — Bilingual Site with Admin Panel & API

A bilingual website and admin area I led for a wellness retreat business, working with a second developer through branches and pull requests. The public site presents retreat packages, travel tips and a Q&A section with an animated hero in Spanish and English. An Express and MongoDB API sends contact and free-guide emails, and a protected admin panel lets the owner review contacts and manage Q&A entries. Built with React, Material UI, Redux and Firebase, and deployed on Vercel.

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.

La Wawita (Technical Test)

This project was created as a technical test for my subsequent entrance into Wawa. The technical test involved creating a mini system with a backend built using NestJS, Prisma, Apollo GraphQL, and MongoDB. The system allowed storing buses and their corresponding routes in separate tables in the database, with the goal of displaying them later in a frontend developed with Next.js. Additionally, the project included displaying the bus route on a Google Maps map.

Magno Evento Inmobiliario 2024

Magno Evento Inmobiliario was a small but very enjoyable system to develop, mainly because it was a project planned on very short notice — just one month before the event, which took place in Mexico City on September 3, 2024. We started working on it around August 10. The system included a landing page with a payment modal that allowed users to purchase tickets for the event using three payment methods: credit or debit card, PayPal, and cash payments through OXXO. All payment methods were implemented using Stripe. I contributed significantly to the payment processing structure, especially for OXXO, which was more complex because we had to implement a webhook to track when users made cash payments and notify our backend to send them an email with their ticket details. The system also included an admin panel to view both paid tickets and pending cash payments. On the event day, we used a QR code sent to the user's email to scan and verify the validity of the ticket.

Star Stats

If I can recall a project that presented a significant challenge for me, it was a betting website, also known as a Parlay, for placing bets on match results and certain player statistics from real sports. This project was developed using TypeScript with highly optimized structures. I worked on it while I was at Kromaticos, as it was a project that came with quite difficult requirements to achieve within the estimated time. The challenges involved using unknown and low-budget sports APIs, which were very complicated to work with due to their poor documentation. We had to use the provided endpoints, and at times, to generate certain results, we had to perform data analysis, highly recursive calculations, and very intensive operations on both our database and the API, which increased its cost significantly, among other issues. Nevertheless, we managed to develop the project and delivered a very beta version of the system, but it worked. It’s also worth mentioning that I implemented the payment gateway and user subscription plans using Stripe in this system.

Viveplus

Viveplus was the first project I developed for Kromaticos, where my main task was to handle the frontend development. In my opinion, it’s one of the best-looking projects I’ve worked on, with a highly polished user interface that is precise, modern, intuitive, and optimized. It’s worth mentioning that this project marked the beginning of my improved use of TypeScript, significantly enhancing code quality by using interfaces, good practices, and structured approaches.
