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
