Top SchoolChris Tankersley is a Senior Developer Advocate with 15 years of experience specializing in integrations at Vonage, primarily working in PHP while remaining a pragmatic polyglot. He drives SDK quality and feature work across Vonage's PHP and Node.js clients—improving messaging, numbers, voice, and verify flows—while championing test-driven refactors and code-style hygiene. A prolific open-source contributor, he has hardened the widely used cron-expression libraries by fixing subtle edge cases (leading zeros, mixed ranges/lists, large-step ranges) and tightening validation to match cron standards. Colleagues rely on him to translate tricky protocol and scheduling semantics into reliable, well-tested client libraries that power real-time communications.
