Java, HCL IBM Lotus Notes client, Domino server, XPages, LotusScript, and @Function expert developer For the past 10+ years, I have focused on the development and modernization of HCL IBM Lotus Notes Client and Domino server applications. I have helped quickly implement everything from Notes Client business logic to lower level Domino server functions. I can build and support both Notes Client based applications as well as Domino server web applications -- in XPages, HTML5, traditional embedded HTML, and modern REST API scenarios. I have a deep understanding with the Domino Java API, the 3rd party JNA helper library that has been gaining popularity, and the Domino C API. I also provide Domino data and application migration and transformation services including SQL import and export. When you want to smoothly migrate your business data and programs from the current Domino platform to other databases, I can help. My greatest strength is to learn any new technology quickly and apply it to work projects, and solve complex and difficult technical problems. During my work with clients and employers, I completed all tasks assigned to me in a timely manner and solved all technical problems. I am a dynamic professional with a strong learning ability and a keen ability to solve complex problems. My expertise lies in making precise technical decisions for system architecture, providing insights for different technology stacks, and reducing potential technical risks. I am good at designing interfaces and functions, and I am proficient in translating written requirements into practical solutions.
