About me
From the sea to software systems.
I'm a former seafarer turned Full Stack Software Engineer. I bring calm, ownership, and a systems-first mindset to every product I build.
My work spans warehouse operations, back-office platforms, analytics dashboards, CRMs, and automation. I enjoy making the complicated feel simple for the teams who rely on it every day.
Beyond application development, I deploy and maintain production environments with AWS, Linux, Docker, Nginx, and secure HTTPS configuration.
“I care about the details behind a dependable product: clear architecture, secure deployment, and a useful experience.”
