Responsibilities:

• Architected/Designed/Implemented multiple projects simultaneously on my own or in small teams, including analytics models (Rental Amount, Disposition, LendOptix, FraudmarkA/B, WatchSuite), model-backing file generation & aggregation system, Logging Service & associated database schemas. One of “goto guys” for algorithms, threading tuning, & hard problems.
• Scala evangelist and one of local language “experts.” Led a language “run-off” complete with benchmarking that was used to select Scala as our language of choice. Then, two of us learned, developed and propagated the language throughout the organization.
• Proposed Modeling Framework “Meta-Architecture”: investigated, documented and implemented new streamlined approach to model development using Scala. Projects that formerly had hundreds of source files and took 3-6 months to develop are now done with roughly 10 source files in 2-4 weeks Some of these time/file reductions were due to the establishing of enabling conventions and parallel analytics development. A new project template is sketched in a Maven archetype and exploded for a new project, also saving time. These improvements accelerated Confidential development cycles, beating schedules & reducing time to market.
• Greatly streamlined model/file validation process from multiple weeks down to days using innovative search/compute/join and automation/match techniques on big datasets, thereby saving time, conserving budgets & eliminating numerous headaches.
• Significantly improved overall analytics model throughput by introducing reliable multi-threading. Designed & coded multi-threaded, Web-enabled test harness to validate.
• One of organization-wide leaders in documentation via MediaWiki. Served on numerous committees (Collaboration, Architecture, Documentation Standards). One of leading contributors to architectural standards committee and led or co-led numerous brown-bags on Scala, our internal Scala framework, the Wiki or architectural topics.
• FraudmarkUK product (team lead): came up with overall architecture & build structure, implemented innovative “Flat POJO persistence framework” that afforded tremendous flexibility & ease of use.
• WatchSuite product (team lead): understood & modeled current “patched together” analytics suite for mortgage fraud detection. Proposed top level architecture & schema; interacted with multiple divisions & data sources. Project now generates over $1M annual revenue.
• Designed, implemented & tested flexible, meta-data-driven database extractor that composes Java-friendly data structure given fairly arbitrary database schema/table/column structures, satisfying multiple product needs, especially those for feeding analytic fraud models.
