About Me
Engineering Leader& AI/ML Specialist
I'm Thooyavan Manivaasakar, an engineering leader with 14+ years delivering SaaS solutions and 4+ years specializing in AI-driven products across enterprise platforms, passionate about AI/ML, distributed systems, and building teams that ship market-first innovations. Currently, an Engineering Manager at HappyFox, I've spent my career transforming ideas into production systems used by thousands of users globally.
I've been recognized by OpenAI for contributions to their Evals project, built the first gen AI-powered analytics platform in the XM space—beating Qualtrics, QuestionPro, and Medallia to market and winning Emirates Airlines, created foundational AI platform layers, and scaled engineering organizations from 8 to 35 members while transforming architectures to handle 100x load. I believe in learning in public, building with empathy, and sharing what works (and what doesn't).
Core expertise: Leading cross-functional teams through complete product lifecycles, from 0→1 initiatives to scaling mature platforms. Skilled in translating complex problems into strategic business solutions while maintaining engineering excellence.
