Technical Lead building scalable event-driven SaaS platforms and leading teams to ship reliably.
IndiaWhat I'm looking for
I’m a FullStack Technical Lead with 9.5+ years of experience architecting scalable SaaS platforms, especially using microservices and event-driven design. I led the re-architecture of a compliance-critical IVR platform from a polling workflow to a Kafka-based architecture, scaling to 100K+ daily calls while improving scalability, system reliability, and database performance.
I also architected a reusable rate-limiting platform for .NET, Go, and Node.js services, delivering standardized middleware for adaptive throttling, queuing, and request shedding using real-time client metrics. I’ve led a team of 6 developers, drive release management and production support, and previously built React component libraries, Kafka-integrated billing microservices, and client-facing Chrome extensions—always focused on resilient systems and measurable impact.
