LiquidityBook Appoints New Principal Software Engineer to Focus on POEMS Platform

January 30, 2019

LiquidityBook has appointed Alexander Ponyrko as Principal Software Engineer, where he will be responsible for a range of development initiatives around the firm’s industry-leading POEMS (portfolio, order, and execution management system) platform and reporting directly to CTO Shawn Samuel.

The leading Software-as-a-Service (SaaS)-based provider of buy- and sell-side trading solutions hired Ponyrko for its more than a decade of experience as a technologist, and in response to growing demand from fund managers who increasingly abandon legacy technology providers in favor of more agile, web-based models. He will be working closely with LiquidityBook’s client service organization to help rapidly implement client-driven development priorities.

As a result, client demand for technology that can be seamlessly integrated into complex workflows is greater than ever. We are thrilled to add Alex, who will lead the way in developing solutions that will keep our clients at the forefront of the investment management space.”
