Alessandro is an extremely knowledgeable search developer, with a rare level of deep insights into the inner workings of Apache Lucene and Apache Solr. Furthermore, his passion and dedication is exemplary, attending meetups, taking time out of work to attend conferences, and working on open source contributions in his own time. It has been a pleasure working with him, and I would definitely hire Alessandro again if the opportunity arose.

Canva solicited Sease’s guidance when we were facing some challenging scale and performance problems with our Solr clusters. Specifically, we had issues with our Solr7 cluster configuration & high latencies on tail queries. They worked with us to understand the key challenges with Canva's implementation of Solr & its various collections. They also worked with us to understand how we were operating our Solr clusters at the scale of 1000 RPS to deeply investigate any fundamental operational mistakes. As a result of this partnership, they provided a very comprehensive report of suggestions for improvement. These suggestions allowed us to smoothly upgrade the major version of Solr to 8. We have also seen improved stability of the service, with a reduction in latency spikes under heavy load.

Strong experience!
Very strong experience, they got the job and worked fast! Most definitely would collaborate again. Andrea is definitely a Solr expert, we really enjoyed having him help us!
