Personal Finance PWA — Offline-First, Firebase Rules & Tests

A personal finance app I designed and built for my own use, tracking income, debts, goals and investments across USDT, USD, COP and VES. It is an installable, offline-capable PWA on React and Firebase with only three runtime dependencies. Balances are always derived from transactions instead of stored, and Firestore security rules validate every write on the server, backed by emulator tests and a differential test that keeps the app schemas and the rules in sync. It also has investment portfolios, Binance import, net-worth snapshots and validated backups. I shipped it with CI and a strict CSP, treating a small personal tool with production-level care.

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.

Mobility Immigration — Law Firm Website, CRM Sync & Admin CMS

I built the website and lead system for Mobility Immigration, a Tampa immigration law firm, for the DotDev and Dulce Marketing agency. It began as a bilingual landing page and grew into a full-stack Next.js 16 product: English and Spanish routes with SEO, 23 visa-pathway pages, a payments page with financing, and a blog on Firestore with ISR. Contact forms are stored in Firestore, emailed through Resend and synced to the firm's Docketwise CRM over OAuth 2.0, with fallbacks so no lead is lost. I also built an admin area with a rich-text editor and tightened the security rules after review.

DotDevPay — Payments Backend (GraphQL, Stripe, Zelle & Pago Móvil)

DotDevPay is a payments platform I am building to make company payment flows easier in Venezuela. The backend is a NestJS GraphQL API on Prisma and MongoDB where businesses create payment links, manage payment methods and collect from clients through Stripe, Zelle and Pago Móvil. I designed each gateway as its own module behind a shared interface, so adding a new one doesn't touch the rest. It also has role-based access for users and super users, a licensing model with service packages, and analytics for links, methods and clients. Error handling, validated configuration, structured logging and per-environment seeds are all in place.

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.

Proyecto Soma

This project was developed as part of a thesis presentation at a local university. The original description within the thesis document included the following: “The system provides a perspective of the sets of elements that are interconnected, a web tool to organize the work landscape and plan the tasks to be completed, avoiding the hassle of paperwork within the department, improving procedures.” The project was based on solving a management problem within a local clinical laboratory.

Muscurehab

A small project developed in record time for a local physiotherapy center. The app's functionality was simple: users could register their profile, select the type of injury they had and its location on the body. Based on this information, the app would recommend specific exercises, and at the end, there was a feedback modal to evaluate the progress of their recovery.

Ek Parts

Ek Parts was the last contract I worked on with Empire Keeway, and it involved creating a mini e-commerce platform to sell motorcycle parts to specific clients across Venezuela. The platform didn’t integrate payment methods, as payments were arranged after placing the order.
