Full-Stack & AI Application Developer

Next.js · Supabase · Flutter · Laravel · LLM Integration

Magna Cum Laude Computer Science graduate and full-stack developer experienced in Next.js, TypeScript, Supabase, Flutter, and Laravel, with hands-on LLM integration (Gemini, Ollama) and AI-assisted development using OpenAI Codex, GitHub Copilot in VS Code, and Google Antigravity, with OmniRoute for routing across multiple AI providers. Built Developer Workplace, a Supabase-backed developer workspace with separate private and public Gemini assistants. Interned at BMWare as a system architect, designing a real-time emergency-response platform and a PayPal-integrated insurance app. Led a thesis project running YOLOv11 on-device with Unity Sentis.

About

Connecting software, systems & AI

I built Developer Workplace, a full-stack developer workspace in Next.js, React, and TypeScript, using Supabase Auth and PostgreSQL Row Level Security. It includes persistent Kanban boards, a drag-to-reschedule calendar, a read-only GitHub App integration, and separate private and public Gemini assistants.

At BMWare, I built Flutter applications with Laravel backends and designed database schemas and system architecture for emergency response and insurance applications. As thesis project lead and system architect, I implemented on-device YOLOv11 inference through Unity Sentis.

    Technical Intern & System Architect

    Internship

    • Built modular, cross-platform mobile apps in Flutter across multiple production projects, integrating with a Laravel (PHP) backend through RESTful APIs.
    • Designed the database schema (ERDs) and microservices for Adsumus Dispatch, a real-time emergency response platform with fallback state synchronization, encrypted messaging, and geolocation tracking.
    • Architected InsureMe, a production digital insurance app, integrating the PayPal SDK behind a decoupled abstraction layer to isolate payment state from app logic and avoid handling payment data locally.
