I have 15+ years of experience with Postgresql from plain SQL queries and standard SQL features like Indexes, JOIN queries and other complex queries, going all the way up to complex programming using PL/PGSQL stores procedures. I have worked before on many Postgres based applications. I also have experience with redis using node.js , A+ Python experience, Database modelling & normalization. Recently I had held helped someone optimized their Postgres server which was poorly optimized to handle tables having millions of records. They had tried many approaches before but mine was able to solve their problem. I have kept this bid a little higher as I'm unsure if you require me to code in node.js , python etc. or if you are looking for just SQL server optimization. If you confirm whether coding is required or not, I could revise my bid accordingly

Hello how are you, I hope you are well, my qualities for this are the great knowledge in Postgresql, sql, creating queries through stored procedures that return multiple records, these queries can be made to work very fast, experience with subsocnsultas, views, etc, I know python, and some javascript, I am responsible with what I say and what I promise to do, this would really be a challenge for me again.
