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.
