Managing transition of filter development methodology, processes, lab resources, test hardware, and test software from Alcatel-Lucent to Nokia. Oversee specification, technical supplier management, and unit level testing to deliver world class LTE and GSM RF filter designs. Engineer filter specification to optimize system architecture. Analyze and troubleshoot filter failures at unit, system hardware, and production level.• Reconfigured filter test lab hardware and wrote test software, reducing test interval from 24 to 5 days.• Brought peak power test capability, identifying design flaws and preventing field recall.

Murray Hill, Nj

Directed all aspects of LTE, CDMA, and UMTS wireless base station RF Filter and LNA development with up to 7-person engineering and technical staff and tens of millions annual spend. Authored design specifications and steered architecture for optimal cost, performance, and size of platform, customer specific, and stand-alone filter products. Managed RF filter supplier’s technical roadmaps, quality improvement teams, development scorecards, and auditing.• Led cross-functional team covering all aspects of filter development including; requirements, head count budgeting, RFP, design specification, test, RFQ, pilot, and production.• Developed ~25 cost-reduced filter designs, saving millions annually. Achieved continual cost reduction through qualification of alternate suppliers and repair services.

Whippany, Nj

Drove system architecture through sub-assembly specification, test, and technical supplier management. Managed RF filter customer designs from 6 leading global filter suppliers. Accountable for field, production, system software, system hardware, and subassembly level filter failure analysis.• Developed RF filter sub-assemblies for remote radio heads (RRHs), macro cell base stations, compact base stations, and ancillary filter products.• Wrote RF filter test and analysis software, employing NI LabVIEW, Perl, UNIX, and VBS, improving qualification intervals from 3 months to 1 week.
