Sithum Liyanage
Director of Technology
Sithum looks after the platform iFormBuilder runs on: the cloud infrastructure, the release process, and the security work customers never see but always depend on. He also leads Zerion’s AI development effort, including Document Builder, which turns collected field data into finished documents. He has a habit of spotting a problem a month before it arrives, and a gift for explaining a complicated fix in plain language. Sithum studied at Penn State.
Stella Park
Director of Customer Support
Stella leads Zerion’s support team and has been looking after iFormBuilder customers for close to a decade. She rebuilt the company’s support experience around the Zerion Help Center, writes much of the documentation and release notes customers rely on, and works shoulder-to-shoulder with engineering to turn a reported problem into a shipped fix. She is relentlessly practical: every process she has put in place exists because it got a customer an answer faster.
Daniella Yeon
Director of Finance
Daniella keeps the business side of Zerion running. She owns the company’s order-to-cash process end to end, from invoicing and renewals to collections, revenue recognition and forecasting, along with vendor contracts, payroll and benefits, and the internal systems the team works in every day. Nearly a decade in, she is the one who spots the discrepancy nobody else caught, and she usually turns up with the fix already worked out. Daniella studied accounting at George Mason University.
