05 / ABOUT

Lifelong learner. Quietly thorough.

My career started with building websites, but I've always been more interested in the problem behind the website.

What does the user actually need? How should the product work? What happens when things go wrong? How can a complicated process be turned into something simple?

That's what eventually led me toward product engineering.

Today, I build web applications and digital products from idea to production. I work across product thinking, UX, frontend, backend, databases, APIs and integrations — using modern AI-assisted development tools to move quickly from an idea to a working product.

I've built products ranging from interactive property platforms to productivity and language-learning applications, while continuing to work with clients on websites and digital experiences.

I enjoy the messy middle of a project: taking a vague idea, figuring out what it actually needs, solving the technical problems, and turning it into something that feels obvious and easy to use.

Give me a problem, an idea, or a messy workflow. I'll figure out how to turn it into something useful.

06 / KIND WORDS

What clients say.

“I’ve had the pleasure of working with Erna for over a year across multiple projects. She’s not only a joy to collaborate with but consistently delivers high-quality work at an impressive pace, even under pressure. Time and again, we’ve given Erna tight deadlines and complex tasks, and she has always risen to the challenge, delivering excellent results quickly and reliably. I wouldn’t hesitate to recommend Erna to anyone looking for a talented, dependable web developer.”
Kirsty Trewhella

"Erna is a deeply trustworthy 2IC on projects which require the synthesis of lots of disparate information. It is always a great relief to have her as a conduit between myself/client and our developers. I can rely on Erna to take a jumble of instructions and documents and quickly form it into a coherent plan. She is attentive and agile as plans evolve or needs change. She cares deeply about the quality of her work. Though always kind, patient and a pleasure to work with, Erna commands respect both from me and the developers she oversees. It is bittersweet to see her outgrow the work I can offer her."

"Erna was reliable and diligent in her role as a Webflow developer. Despite what was a unique project, she showed a strong willingness to be flexible within new workflows/teams, learn and adapt to new systems/modalities. Her communication was consistent and clear throughout and followed up with diligent work. Thanks Erna"
