About

A short introduction.

I'm a full-stack engineer who likes building software that holds up — clean, scalable, easy to reason about months later. Day-to-day that means React and TypeScript on the front, .NET and SQL Server on the back, and Azure tying it together.

Full-stack loan servicing tooling at Interfi Systems

Experience

A short history.

  1. Earlier

    First lines of code

    Started writing Visual Basic as a kid, mostly to mess around. That turned into Java and C# for game development through the school years — long before any of this was a career plan, just curiosity that wouldn't quit.

  2. 2018

    Started university

    Monash University — Engineering & Pharmaceutical Science

    Began a dual Bachelor of Engineering / Pharmaceutical Science. By then I'd been writing code as a hobby for years, and it didn't take long to realise I'd ended up on the wrong degree.

  3. 2023

    Made the pivot

    Stepped away from the dual degree at Monash and committed fully to software. A deliberate decision — pharma wasn't where I wanted to land, and waiting out a credential I no longer needed wasn't going to change that.

  4. 2024

    Bootcamp & freelance work

    Completed the Codecademy Full Stack Engineer Bootcamp and a dedicated .NET course. Started taking on freelance projects — building responsive UIs, structured APIs, and cloud-deployed apps for small business clients alongside personal builds.

  5. Now

    Full-stack at Interfi Systems

    Software Engineer · Sept 2024 – present

    Building and maintaining full-stack systems for loan management and internal analytics. Day-to-day mix of React + .NET feature work, complex SQL stored procedures, Azure-based observability tooling, and integrating with banking partners.

Projects

A few things I've built.

Side projects and explorations. The kind of small, finished thing that's more useful than a half-finished bigger thing.
