About

An engineer wired for shipping.

Since December 2023 I've been part of the engineering team at E-Power CCL, working across four real-world products — Solar, EAC App, Mobile Billing, and ePower Maps — owning slices of backend, frontend, and ongoing maintenance. I learn fast, write practical code, and stay calm under deadlines.

Backend Engineering

REST APIs, data modeling, and system design with Node.js, .NET, and SQL/PostgreSQL.

Frontend & Web

Modern web UIs with Next.js, React, and a deep HTML/CSS/JS foundation.

Mobile (Flutter)

Cross-platform iOS & Android apps with Dart 3, REST integration, and offline flows.

DevOps & Cloud

Docker, Kubernetes, AWS, Render, Supabase, Firebase — shipping and keeping things up.

AI-Augmented Builds

Pairing with Claude, ChatGPT, Gemini, Codex & Grok to ship faster without losing the craft.

Leadership & PM

Project management & team leadership for outsourcing — scoping, planning, delivering.

Experience & Education

From classroom fundamentals to production code.
