LiquidityBook Names Alexander Ponyrko Principal Software Engineer

NEW YORK — January 29, 2019 — LiquidityBook, a leading Software-as-a-Service (SaaS)-based provider of buy- and sell-side trading solutions, today announced the addition of Alexander Ponyrko as Principal Software Engineer.

With over a decade of experience as a technologist, Mr. Ponyrko, who reports directly to CTO Shawn Samuel, will be responsible for a range of development initiatives around the firm’s industry-leading POEMS (portfolio, order and execution management system) platform. He will work closely with LiquidityBook’s client service organization to help rapidly implement client-driven development priorities that SaaS-based platforms like LiquidityBook’s make possible. Mr. Ponyrko arrives at the firm at a time when an increasing number of fund managers are abandoning their legacy technology providers in favor of more agile, web-based models.

Throughout his career, he has led teams of programmers that excel in building cutting-edge technology solutions for firms with complex workflows.

Commenting on the hire, Sean Sullivan, Chief Revenue Officer at LiquidityBook, said: “As more fund managers have begun to see the benefits of a SaaS-based software provider, our business has grown considerably. 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.”

Mr. Ponyrko added: “Throughout my career, I have enjoyed the challenge of building industry-leading solutions with a user-first sensibility. With its dedication to providing client-driven enhancements, it is clear to me that LiquidityBook shares these values. I am truly excited about the work we are doing to help our clients trade as efficiently and effectively as possible.”
