Feedback - Sease

What our clients say about our services

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.

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.

I recently took the course on Apache Solr Neural Search and I must say it was really good. Alessandro and Ilaria were very knowledgeable and presented the material in a clear and concise manner. They went over the contents at a reasonable pace giving enough time for questions at the end of each section. The training was extremely helpful in understanding the concepts and implementation of vector-based search in Solr.
I highly recommend this course to anyone looking to avail of Solr neural search capabilities to improve search experience.

I can wholeheartedly recommend the Neural Search end-to-end training (whether OpenSearch or Solr or Vespa) from Sease for real world search engineers and tinkerers. Alessandro and Anna bring their experience and enthusiasm working deep inside the opensource Lucene ecosystem. They are folks in driving seats moving the field forward from the trenches. I have some experience working in search, and yet the opportunity to gain from Anna and Alessandro’s insight into the nitty-gritties of this bleeding-edge transformation the field is going through makes me a better dense search tinkerer today than I was yesterday.

Alessandro provided an extremely personalised and highly engaging 1-to-1 training, and kept extreme patience to explain and proof details of lucene and elasticsearch internals in his teaching. Overall we discussed a lot of things in capacity, the guidance made me build strong foundations and moved quickly into advanced areas. It has been a pleasure learning under his guidance.

The training has prepared me well to tackle my own project. It helped me to understand how to set up the project and which tools or algorithms I can use for it. The content of the training is quite compact, but not overloaded, so that there was also time for individual questions. I particularly liked the fact that Alessandro shared his experiences from older projects, which allowed him to point out potential problems.

It was a jump into the cold water but was definitely the right thing to do for me. The training helped me a lot to get an orientation where information retrieval and search are going. Antonio is a great source of knowledge and has a lot of experience of what works and what does not. Highly recommended!

The course has certainly generated many interesting ideas, but first we have to fill some gaps.
The positive feedback I had about your professionalism and skills in the areas of information retrieval and AI makes me think that you can definitely be an important partner for the growth and development of our products.
