With his background in finance, Blum has served as special counsel and advisor to national banks, hedge funds, credit unions, RIAs, and loan servicers on defensive strategies in securities, banking, and real estate litigation, authoring statewide bank policy on New York-specific litigation strategies on various case issues.

In his transactional and advisory practice, Blum advises credit unions and lenders on financial product structures in connection with his clients' mortgage banking businesses. Blum serves as general counsel to domestic and international businesses on financing transactions, corporate organizational structures, and intellectual property.

Prior to attending law school, Blum wrote computer software. He applies that expertise extensively in his litigation practice. For example, Blum has assembled and managed teams of attorneys, engineers, and data analysts in eDiscovery and ESI investigations, which have entailed review and analysis of millions of documents. Blum has created eDiscovery platforms and automation tools that have been used to analyze voluminous document productions in connection with public offerings, securities filings, loan and bond underwriting transactions, payroll and check registers, time records, and other electronically-stored materials used in securities cases and other complex class action litigation.
