Yitzchok Gottlieb is a seasoned software architect and manager with 16 years of experience building high-throughput, maintainable systems and leading teams through large-scale migrations to cloud and microservices. He has repeatedly driven exponential customer and order growth—re-engineering SaaS marketplaces in C#, MongoDB, and Elasticsearch to enable a 1000% customer increase and later implementing RabbitMQ and Azure to support a 600% surge in orders. As a hands-on freelancer and founder, he built mission-critical systems including an IVR-enabled ordering platform that handles 1.5K calls/sec, a recommendation engine that improves sales, and contributions to the ShopifySharp .NET library for Shopify GraphQL integrations. Equally comfortable in enterprise and startup contexts, he emphasizes testability, stability, and keeping “software soft” so teams can iterate rapidly. Active in the developer community as a co-founder of NYALT.NET and a featured speaker, he pairs deep technical craft with a knack for practical, business-focused solutions.
