I started my career in banking and medical coding before moving into software engineering in 2022. That path taught me customer focus, accuracy and domain awareness, which I bring into every product I build. Since then I've grown from trainee to Senior Software Engineer, working across sports, HR, compliance, healthcare and social media analytics.
