About Me

My Introduction

I'm a full-stack developer and system designer currently working at a digital marketing agency, where I build and maintain production systems handling advertising data, campaign reporting, and client budget tracking at scale. My work spans the full stack — from designing clean UIs and intuitive user flows to building Python/Flask backends, REST APIs, webhook pipelines, and cloud-based automation. I consult directly with clients, lead development collaborations, and architect end-to-end solutions that hold up under real workloads. I write modular, scalable code and have a strong instinct for optimization — I don't just patch tickets, I own the system.
