In my recent role, I developed internal applications using Oracle APEX, working across frontend Ul, backend logic, database processing, and integrations. I have hands-on experience with service-based workflows, where web applications triggered backend endpoints to generate PDF reports and execute cross-database procedures. I also worked closely with testing, deployment, and production support, ensuring system reliability in a regulated environment. While my background is primarily in Oracle-based technologies, the core concepts I work with-web development, backend services, REST-style integrations, SQL, and SDLC practices-are directly transferable to modern stacks such as ASP.NET Core and Angular. I am comfortable adapting to new technologies and confident in contributing quickly.
