Gjorgji Kjosev is a Senior Software Engineer based in London with 14 years of experience building backend systems, developer tooling, and scalable services across startups and large companies like Apple and DRW. He has led teams and shipped open-source infrastructure—designing an extensible document editor, a fast diff algorithm for legal docs, and tooling like wsrun and h4bff while at H4. Deeply pragmatic, he contributed to high-profile OSS projects such as Bluebird (core promise library) and node-sql, improving error handling, SQL dialect support and performance at the library level. His background spans full-stack product work (including a SeedCamp-backed CTO role) to platform automation for Apple Maps, showing comfort with both low-level implementation details and system design. Known for turning complex traversal and caching problems into practical, performant solutions, he also brings hands-on DevOps experience with CI/CD and containerized testing. He combines academic grounding in intelligent information systems with a track record of shipping robust, production-grade systems and developer-facing tools.
