Performance Optimization
I was a lead developer responsible for rethinking how works and is performing search engine of a one of most popular price comparison sites in Poland. There were multiple challenges, like providing option to filter through hunderds of properties of the products and still deliver it to the end users in the most usable way from UX perspective. Ended builiding plugins to Solr in Java and incrementally tweaking the way search worked. What's important after all those years the setup I made is still working on production. Plus there were 3 other alternative systems that were evaluated but mine win in terms of speed, accuracy and quality.
