Build Custom APIs using Python and Flask (FastAPI also possible and better for unit testing if needed, https://fastapi.tiangolo.com/)
I am versed with SQL and No-SQL (Like CosmosDB hosing Casandra or MangoDB, or a JSON DB). I also have some understanding of Langchain for Link DB Design if needed (Usually for ChatGPT integrations)
I also have experience with GitHub repositories and Actions for CICD work as well as Azure DevOps Server (or Services, cloud native)
