As software engineer, I've worked as a freelance and by contract with a variety of clients in industries of management systems from micro and small enterprises to government software. I've worked on projects from conception to delivery, as well as smaller features and enhancements. I excel at problem-solving, leveraging tools such as Java Reflection API and Generics to create reusable, abstract code that adheres to SOLID and DRY principles. In the front-end, I've developed clean, reusable components for dashboards and CRUDs using WEB based frameworks. In the back-end, I've created and consumed REST/SOAP APIs, implemented scraping using JSOUP, Selenium, and generated reports using tools like Itext, and JasperReports. I prioritize collaboration with clients and team members, and I've successfully delivered projects that meet their requirements. My code enhancements have improved performance and reduced errors, resulting in satisfied clients and successful projects. Show less
