Hariharan breaks complex systems into traceable parts and uses the evidence to locate the underlying issue. At RK Group, he reconciled each device across customers, warehouses, returns, and write-offs. At MPL, he separated client and server events to diagnose game drop-offs. His consulting work applied the same discipline to workflows across finance, sales, people, and operations.

Hariharan has improved consumer products through research, journey design, engagement mechanics, and commercial experiments. At MPL, this work helped Call Break become a top-three revenue product. At Licious, he redesigned discovery and purchase flows to improve growth, visibility, and conversion. Both stories connect customer behavior to measurable product changes.

Hariharan carries work from problem definition through requirements, testing, launch readiness, and operating measurement. He built Convexa's behavior, guardrails, and QA cases, developed software requirements for RK Group's commerce operation, and digitized workflows across a home-services business. The work spans product experience and the systems needed to run it.
