A Bit
About Me
I'm a Senior Software Engineer with 5+ years of experience building scalable enterprise applications and AI-powered SaaS platforms. Currently at Sitecore, I build enterprise features for Content Hub — a leading Digital Asset Management platform used by global enterprises including Microsoft and Foodstuffs New Zealand.
My expertise spans full-stack development with React, Next.js, Node.js and .NET, through cloud infrastructure and DevOps on AWS, Azure and Kubernetes. Alongside my day job I build and launch my own AI-powered SaaS products, mentor junior engineers, and share what I learn on YouTube as CodeByUltra.
Delivering reliable, high-performance software in Agile environments
e-commerce and SaaS for international clients.
