Teodor Sigaev is a seasoned database engineer and technology leader with over two decades of deep PostgreSQL expertise, co-founding Postgres Professional and serving as its CTO while remaining a Major Contributor and Committer to the PostgreSQL project. He helped create PostgreSQL’s full-text search system and has driven work on GIST/GIN indexes, SQL/JSON NoSQL features, and novel index access methods including spatial indexing. His background spans high-scale production systems at Mail.Ru—where he architected storage, search solutions, and an Nginx rate-limiting bot detection system—to founding projects and freelance work for enterprise clients. Notably, his open-source contributions include substantive fixes and features in the official postgres repository, such as improving tsearch2 robustness and adding websearch_to_tsquery for web-like search syntax.
