TaskFlow

Full-stack productivity app with categories, priorities, due dates, filtering, and persisted task data.

Next.js React TypeScript Tailwind CSS Prisma SQLite

QuizApp

Native SwiftUI quiz app for iOS and macOS from a shared codebase — quiz creation, multiple-choice gameplay, score tracking, attempt history, local persistence, shared scoring logic in a separate package.

Swift SwiftUI SwiftPM iOS macOS

Stable Diffusion macOS Metal

Local SDXL environment for Apple Silicon using Hugging Face Diffusers and PyTorch Metal/MPS, generating images offline from terminal prompts after model download.

AI & Local Intelligence

AI-powered applications and local-inference integrations, including model APIs, Apple Silicon workflows, and developer-facing AI tooling.

Apple Platform Development

Native applications and developer tooling for macOS and iOS using Swift and SwiftUI, with an emphasis on thoughtful Apple-platform experiences and systems-oriented software.

Modern Web Applications

Responsive frontend and full-stack web applications built with modern JavaScript and TypeScript technologies including React and Next.js.

About

I'm a developer based in Miami, Florida, working across AI, Apple platforms, systems engineering, and modern web development.

My background is rooted in Information Technology and Computer Engineering. I earned a Bachelor of Science in Information Technology from Florida International University and an Associate in Arts with a focus on Computer Engineering from Miami Dade College. That foundation sparked my interest in understanding how software, operating systems, networks, and infrastructure work together.

Combined with hands-on technical support experience, that foundation took me from troubleshooting systems to building them. My work has ranged from contributing to a collaborative Web3 hackathon project to building Swift tools, native Apple applications, local AI environments, full-stack web applications, and reproducible evaluations of AI coding agents.

Today, I continue to deepen my work in AI, Apple platforms, systems engineering, and the web by building real projects, exploring new technologies, and tackling increasingly challenging engineering problems.
