I'm Prasanna Dangalla, a seasoned software engineer with over 12 years of experience in the technology sector, specializing in API management, integration testing, and software development. With a robust foundation in Java/J2EE,, PHP, and JavaScript, alongside frameworks like ReactJS, NodeJS, and Spring Boot, I've built a career on innovation, problem-solving, and a relentless pursuit to drive growth through technology. My journey began at Thinkcube Systems Pvt Ltd, where I led technical teams in developing cutting-edge business applications and single sign-on services, leveraging technologies such as PHP, Apache2, SAML, MongoDB, MySQL, and the Zend Framework. This experience honed my skills in team leadership, project management, and the development of secure, scalable software solutions. Joining WSO2 was a pivotal move, where I immersed myself in the intricacies of API management, contributing to major releases of the WSO2 API Manager. I led the development of key features, such as the JWT Token Issuing module, PKCE integration, and a significant shift from Opaque tokens to JWT tokens, enhancing performance and security. My role expanded to leading the API Manager support team, mentoring juniors, and managing critical support incidents, underlining my capabilities in leadership, technical guidance, and crisis management. In addition to my development work, I have played a crucial role in testing and quality assurance. I spearheaded the rewrite of WSO2 API Manager integration tests using Java REST APIs, aligning with Agile practices to ensure comprehensive coverage and high product quality. My efforts in creating a UI testing integration pipeline with Cypress and Jenkins demonstrated my commitment to enhancing user experience and fostering a culture of continuous improvement. External engagements have also been a cornerstone of my career. I've consulted for esteemed organizations, providing expertise in WSO2 API Manager and Governance Registry setups, and developing successful proofs of concept for SOA Governance projects. These experiences across different geographies, from Bulgaria to the USA, have enriched my professional outlook, emphasizing adaptability, client-centric solutions, and cross-cultural communication. My academic background, with postgraduate diplomas in Computer Science and Information Systems Management from the University of Colombo, and an AWS Certified Solutions Architect – Associate credential, underpins my practical experience with a solid theoretical foundation. On Upwork, I seek to leverage my expertise to help your business overcome its most challenging technological hurdles. Whether it's developing innovative software solutions, leading tech teams to success, or consulting on complex integration projects, I bring a wealth of experience, a problem-solving mindset, and a dedication to delivering excellence.
