About Kasun Peiris

With over 15 years of experience in frontend development and 10 years in backend development, I am a Team Lead and Full-Stack Developer specializing in UI/UX design, scalable web applications, and enterprise solutions. My expertise spans frontend, backend, and database development, allowing me to architect and deliver high-performance, user-centric digital experiences tailored to business needs. As a frontend specialist, I leverage HTML5, CSS3, SASS, JavaScript, Angular (12+), React, jQuery, Kendo UI, and Bootstrap to create interactive, accessible (WCAG-compliant), and engaging user interfaces. My focus is on responsive design, performance optimization, and seamless user experiences. On the backend, my proficiency in C#, ASP.NET MVC.NET Core, and SQL Server enables me to develop secure, efficient, and scalable applications. I have extensive experience in Sitefinity CMS, where I design custom widgets, dynamic modules, API integrations, and enterprise-level implementations to enhance content management and personalization. In my leadership role, I mentor and guide development teams, driving Agile methodologies, best coding practices, and efficient project delivery. I have a strong background in DevOps, including CI/CD pipelines, cloud deployments (Azure, AWS), and version control (Git, Azure DevOps, GitHub Actions). My expertise ensures seamless integration, deployment, and optimization of applications in cloud and on-prem environments. I am Microsoft Certified: Azure Developer Associate, demonstrating my expertise in cloud-based development, Azure services, and modern application architectures. I am passionate about innovation, problem-solving, and collaboration, ensuring that both my team and the projects we deliver exceed expectations and align with business goals.
