As a Senior Software Engineer, I have over 8 years of experience in building high-quality web applications using React, Node.js, and TypeScript. I am passionate about ensuring code reliability, scalability, and performance through comprehensive testing and optimization techniques. I have led a team of developers for 5 years in the successful delivery of a bespoke betting platform for a top UK betting company, as well as multiple other products within the betting industry. I have also collaborated closely with designers and QA engineers, ensuring user satisfaction and system stability. Some of my key achievements include- Decreasing database load by 40% and improving response time by implementing a caching system for an API for third-party consumers- Reducing frontend load time by 30% and enhancing user experience by optimizing loading speed- Initiating the migration of a monolithic frontend into micro frontends, facilitating faster releases and easier maintenance- Improving stability and reducing e2e tests processing time by 4 hours by redesigning test cases and automated tests- Increasing test coverage of various products from less than 50% to 88-97% by introducing new build tools and implementing SonarCloud- Implementing a comprehensive system for analysing complex data issues, leading to proactive issue identification and resolution, thereby reducing system downtime
