Top expert inPHP Development and E-commerce Web Technologies
Kamil Kokot is a Staff Engineer based in London with 12 years of backend-focused PHP experience, currently driving engineering at Lendable. He is a seasoned maintainer and contributor to major open-source projects—most notably Behat and the Sylius eCommerce ecosystem—where he’s handled releases, upgrades across Symfony and PHP versions, and CI/test architecture improvements. Kamil combines hands-on bug fixes and new feature work (payments, auth, soft deletes, validators) with higher-level responsibilities like roadmap planning, security triage, and architectural decisions. He has a track record of shaving test times and restoring legacy compatibility while keeping projects forward-compatible, a skill that proved crucial during migrations from Symfony 2/PHP5 to Symfony 5/PHP8. Comfortable mentoring and training external teams, he also supports adopters post-launch to ensure successful deployments. An often-overlooked strength is his focus on developer experience—maintaining lockfiles, CI matrices and testing tools (FriendsOfBehat/phpspec) to make large PHP projects safer and faster to change.
