I have been working in InterSystems for more than 10 years so I have a strong knowledge about their technology (Caché, Ensemble, IRIS). I have tons of experience with HL7 and other integration scenarios. In my free time, I develop mainly in dotnet core and javascript (I love VS Code). I have enough skills with Angular and Node.js. I enjoy with all new wonderful devops world working with Docker, deploy on the cloud and all of that. Well, I like to do the things right more than fast, and to share and compare options is very profitable.
