I'm Kirsty, a senior software engineer with a background in both design and computer science. Over the last 15 years, I've worked with early-stage startups in the US, UK, and Canada — helping founders turn ideas into scalable products. With experience in both San Francisco and the UK, I thrive in small, fast-moving teams, especially at the seed and Series A stage. I wear many hats — engineering, product, UX — and bring a Swiss Army knife skill set to every project. I'm passionate about building intuitive, high-quality experiences that balance design and technology. Alongside my solo work, I run StackTiger, a micro-agency where we build MVPs for startups.
