About Sagar Damera

I am a Senior Software Engineer L2 with over 10 years of experience in designing and developing scalable, high-performance web applications. I bring a strong foundation in front-end development using JavaScript, React, HTML5, and CSS3, complemented by 3+ years of backend experience in Java and Spring Boot. My professional background includes significant contributions to the banking and financial services domain, with hands-on experience in developing secure, compliant, and enterprise-grade solutions for institutions such as Wells Fargo and American Express. I have delivered mission-critical applications including customer onboarding systems, financial dashboards, and transaction management platforms—ensuring performance, reliability, and regulatory adherence. Skilled in building full-stack solutions, I have a deep understanding of component-based UI architecture, state management frameworks (Redux, Formik), and RESTful API integration. On the backend, I work extensively with microservices architecture, Spring Security, JPA/Hibernate, and relational databases like MySQL, LeapLogic, and PostgreSQL. I am an advocate of clean code, SOLID principles, and design patterns, and I actively engage in agile development, code reviews, and cross-functional collaboration to drive technical excellence across the software development lifecycle. Passionate about delivering robust, user focused applications that align with business goals especially in complex, regulated environments such as finance.
