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.

I had the pleasure to work with Alessandro and Sease team for over a year and a half. His team was contracted to Search and Discovery team at Alfresco. As a team lead I was very lucky to get such support. Without their input we would not be able to achieve the business goals in the time limits. Their diligent and highly professional work helped not only to make the Search project successful, but also to grow the skills and expertise inside the team. They were able to coach and mentor the developers, provide internal training. Their deep knowledge of Solr and Elasticsearch helped to overcome a lot of complexity and deliver the necessary features and improvements to our customers in a timely manner.

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.

Alessandro was able to assess and contribute to our implementation of solr quickly. His insights were useful for our team and have provided our engineers with both guidance and solid improvements. Professional attitude and excellent understanding of Apache Solr and Zookeeper.

Alessandro and his team at Sease really helped me get my search and semantic engine project off the ground and going in the right direction. Our project was able to deliver a policing domain specific entity management (vehicles, known offenders, gangs, drugs, and weapons), detection, and enrichment solution because of their deep knowledge of, and best implementation practices around Apache Stanbol. Going beyond solution design, Alessandro and Sease were able to resolve a number of high-level conceptual incongruities in the solution architecture as well fix several low-level configuration / runtime issues. This included bug-fix and code merging into the Apache source track. It was great having a team the could see the big picture and have the hands on experience to get the job done at a very reasonable cost while working well with our project team. Thanks again

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!
