Senior🎓
Top SchoolJosh Priestley is a Senior Full-stack Developer with 15 years' experience building and operating high-availability web and serverless systems, particularly for live sports events such as the Australian Open and Laver Cup. He combines hands-on engineering (Node.js, TypeScript, AWS Lambda/CDK) with technical leadership—planning architecture, CI/CD and 24x7 live support as a solo operator under peak load. His background spans legacy .NET monoliths to modern serverless migrations on Azure and AWS, and includes low-level contributions to the widely used Yii PHP framework (improving logging and database migration subsystems). Comfortable leading small teams and mentoring through strategy pivots, he has repeatedly delivered resilient, scalable scoring and notification platforms that handle thousands of requests per second. Based in the UK and recently settled in Melbourne after a motorbike journey, he brings a practical blend of operational rigor and adventurous problem-solving to complex production challenges.
