About

A bit about me

I'm a full stack developer based in Panamá with over four years of experience building web and mobile applications. I currently work at BlueCore, crafting mobile banking apps for the financial sector with Ionic and Angular, before that I spent three years at Etyalab shipping web products with Vue, React and Next.js.

I work across the stack with TypeScript, Node.js and PostgreSQL, and lately I've been building AI-powered side projects like a gym routine manager with vision-based equipment recognition and a voice-first app for practicing spoken English. As a full stack developer, I enjoy working with a wide range of tools and technologies, and I'm always looking for ways to improve my skills and knowledge. Being able to work with projects that actually change people's lives is a dream come true to me.

Outside of code: I enjoy sports, pop culture movies, tv shows, and video games. I'm a big fan of football, enjoy watching italian Serie A matches and playing FIFA (or A.K.A nowadays as EA Sports FC lol) with friends. Also, I like reading books, or listening to audiobooks lately.

Projects

Gym Routine Manager screenshotLive

Gym Routine Manager

This is a full-stack web app for building and managing personalized gym routines, powered by AI. Users create weekly routines organized by muscle groups, then use the built-in AI analyzer to identify gym machines from a photo — Claude Vision recognizes the equipment, lists the muscles it targets, and generates step-by-step exercises. Analyzed machines are automatically surfaced inside the relevant routine days based on muscle group matching.

Chatterly screenshotLive

Chatterly

Chatterly is a voice-first web app that helps users practice spoken English through real-time AI conversations. Users speak directly into the browser — their audio is transcribed via Groq Whisper, processed by a LLaMA 3.3 70B model, and replied to using Azure Neural Text-to-Speech — creating a natural, immersive dialogue loop.

URL Shortener screenshotLive

URL Shortener

A production-ready URL shortening service built with Go, featuring a REST API, PostgreSQL persistence, and a server-rendered frontend. Implements FNV-32a hashing for short code generation, per-request logging middleware, and click tracking per shortened URL. Containerized with Docker Compose for one-command local setup.

Funny Math App

Live

This a calculator app that can calculate basic math operations like addition, subtraction, multiplication, and division. Made with React 18 when it just came out. I tried to make an unique style for the buttons and the inputs, not a complex project but gets tricky on the right control of the operations and context maintaining.

Tic Tac Toe game

Live

Tic Tac Toe is a classic game that can be played with two players. It is a simple game that is easy to learn and play. I made this game using vainilla JavaScript, HTML and CSS. I host the game using the GitHub Pages service that makes it super easy to settle a continuous integration pipeline with every merge to master branch, it is available online now.

To-do App made with Vue.js

Live

A simple to-do app made with Vue.js I made with vue cli, bootstrap and data persistence with local storage. You can create new tasks, edit a task, mark a task as completed, put back to uncompleted or delete a task, only using the local storage to store the tasks go we do not need to use a database.

Rick and Morty Wiki

Live

I developed a Rick and Morty character Wiki using the official API to fetch detailed character information. The app also features pagination by leveraging the API’s built-in properties. This project was a great way to sharpen my vanilla JavaScript skills, and it was built entirely with HTML, CSS, and JavaScript.

Country Finder App

Live

This application allows you to find countries by their name or by its continent. Made with vue and bootstrap. Develop this application was really fun and helped me learn more about vue, vue lifecycle, components, conditional rendering and other stuff i was really new about at the time.
