Konstantin Pelykh — Search & AI Engineer

About

From Big Data pipelines to neural search architectures — my journey has always been about making information accessible. Based in New York, I've spent nearly two decades building systems that help people find what they're looking for.

With dual Master's degrees in Computer Science and Linguistics, I bring a unique perspective to search technology — understanding both the engineering challenges and the nuances of human language. My work spans from low-level Lucene codec optimizations to integrating LLMs for semantic understanding.

I believe the future of search isn't about matching keywords — it's about understanding meaning.

What People Say

I had the great pleasure of managing Konstantin for over two years. He's one of the most talented engineers I've had the fortune of working with in my career. No matter how big or complex the task, Konstantin would take it on with a humble 'sure' and consistently deliver high-quality work on time. He has a deep understanding of search technologies, especially Elasticsearch and Lucene.

Elad Sheinfeld Former Manager, GrubHub

Konstantin and I worked on a number of projects over the last two years ranging from building search systems to job schedulers. He is very enterprising and has the prized skill of solving ambiguous problems. He is equally good at working independently as well as in close collaboration. He comes with my highest recommendations.

Skand Gupta Former Manager, Bloomberg

Konstantin is perhaps one of the best programmers I have ever worked with. He's one of the few developers that have a full understanding of programming and computing fundamentals and not just language nuisances. While he was at Zettaset we worked closely together to develop groundbreaking distributed security constructs and frameworks.

Brian Christian Former CEO, Zettaset

Konstantin is a hands down 10x engineer. He has the ability to understand crux of the business problem and come up with a thorough and solid solution. Konstantin is one of the few engineers that has solid understanding of Big Data, Search and Java/J2EE technologies. He never gives up until he finds root cause to a problem.

Anil Kona Former Manager, Xactly

Konstantin is one of the best software engineers I'd ever worked with. He's a true scientist when it comes to complex algorithms, his ability to research and implement best solution possible is simply amazing, and his work ethics and dedication is absolutely exemplary. It was a true pleasure and a privilege working with him!

Arthur Svider Head of Engineering, Bizzy

Konstantin's approach to the project was impressive and his focus to understand the detail of our business operations gave us confidence. The delivery materialized on time and was deployed with his help, advice and oversight. His genuine interest in the project is refreshing — a rare trait indeed in the formal business world.
