About

I design and deliver intelligent products that stay close to the people who rely on them. From custom software tools and data pipelines to AI workflows, interface craft, and release planning. I take ideas from exploration to adoption while keeping business outcomes and user trust front and center. I work shoulder to shoulder with stakeholders, engineers, analysts, designers, and leadership, translating technical detail into the choices that move a product forward.

Years in tech have given me depth across full stack. I have built resilient backend services, stood up data platforms, brought AI features into production, and shipped award winning interfaces. Recent projects have ranged from Kafka powered streaming pipelines to mobile experiences in Swift that earnt recognition at the UTS Tech Festival 2025 - Software Engineering Showcase for Best Interface Design. Along the way I have coached younger engineers, facilitated design reviews, and kept delivery rhythms aligned with stakeholder expectations.

My edge comes from the chapters outside pure engineering. Leading homage specialty coffee and Petit by Herman taught me how to build teams that thrive, protect customer experience when pressure is high, and run operations that guests remember. Earlier, monitoring credit risk at Idea Bank gave me a feel for regulatory pressure, financial storytelling, and the executive conversations that follow. Those experiences trained me to read the room quickly, build consensus, and make complex work easy to grasp.

Think of me as the person who can switch hats as the moment demands: the engineer who understands the business picture, the product partner who clarifies direction, the leader who keeps delivery disciplined, and the designer who makes the whole thing feel intuitive. If that combination is what your team needs next, I would love to talk.
