What I'm looking for

I seek a technically challenging role where I can lead feature development, mentor engineers, work with modern web stacks and cloud infrastructure, and deliver scalable, maintainable systems within collaborative product-focused teams.

I am a Senior Full Stack Developer with over 12 years of commercial development experience, including more than a decade in full stack work and four years as a freelancer. I specialize in building scalable, high-performance web services using modern JavaScript frameworks, Python, and Node.js, with a strong emphasis on maintainable, future-proof architectures.

Throughout my career I have led migrations of legacy systems, built data analytics dashboards, and improved system performance and uptime using cloud platforms like AWS and GCP. I have experience designing REST and GraphQL APIs, containerizing applications with Docker and Kubernetes, and implementing CI/CD pipelines to accelerate delivery.

I am recognized for a problem-solving mindset, efficient coding practices, and leadership—mentoring teams, conducting code reviews, and collaborating closely with product and design stakeholders to drive projects from conception to production.
