Software Expert Witness Opinion Areas
Applied across industries. Anchored to international standards.
Technology, Product Development & Software Engineering
The core discipline. Applying industry-standard design, testing, and post-deployment evaluation methods across industries since 1988.
SDLC/PDLC Governance & Technical Causation
When software projects fail, causation requires systematic governance analysis benchmarked against ISO/IEC and IEEE standards.
Platform Architecture & System Design
Enterprise-scale platform evaluation — API design, cloud migration, and mission-critical system governance.
E-Commerce, Affiliate & Loyalty Program Technology
Building the systems attorneys now litigate, since 1988. Expert declarations cited in a published Federal Circuit opinion, cxLoyalty v. Maritz, 986 F.3d 1367 (Fed. Cir. 2021).
AI Governance & Algorithmic Accountability
Evaluating AI-weighted models, algorithmic decision systems, and product development methodology for safety-critical AI deployments.
Standards Conformance (ISO/IEC, IEEE, ACM)
Every opinion anchored to internationally ratified standards: ISO 31000, ISO/IEC 12207, ISO/IEC 25010, IEEE 730, OWASP.
Source Code Expert Witness
Hands-on source code review and comparison across patent, copyright, and trade secret disputes, applying the Abstraction-Filtration-Comparison method.
Banking, Payments & Enterprise Financial Systems
Core and online banking, payments messaging (ISO 20022, Fedwire, SWIFT), and enterprise platforms (BPM, ERP, books-and-records systems), from the expert who led the New York Fed Markets Group's ISO 20022 transition.
Central Banking & Financial Market Infrastructure

Technology & Product Leadership · Since 1988
Bruce retired from the Federal Reserve Bank of New York as Vice President, Chief Product Owner - Markets Group, after 14 years at the Bank, where he was Operating Sponsor and Product Leader for the Markets Transformation Program, led the Markets Group transition to the ISO 20022 standard, and developed and launched SOFR. His career spans Princeton (BSE, 1988, Magna Cum Laude) → Booz Allen → American Express (Vice President, Technology) → First Manhattan Consulting → Brierley & Partners (CTO) → United Airlines (VP/CTO, UAL Loyalty Services) → Novantas (Managing Director) → Weiner.Net, LLC (formed 2004; operating since 2008).
Since 2011, Bruce has been retained as a testifying and consulting expert in 30+ matters involving technology, product development, and software engineering — an even plaintiff/defense split. 10+ depositions, with live testimony experience.

A Structured, Standards-Based Methodology That Mirrors Industry Practice
Bruce applies the same analytical framework he has used in technology leadership since 1988: establish clear questions, apply experience and recognized frameworks, gather and review extensive documentary evidence, and measure processes against articulated goals and standards. This approach — anchored to ISO 31000, ISO/IEC 12207, ISO/IEC 25010, and IEEE 730 — produces opinions that are systematic, objective, and reproducible.
