Led modernization of the Acquisition Lane, including the digital application and origination funnel, and delivered an instant loan-disbursement workflow capable of funding debit cards within minutes. Served as Software Architect for the lane before transitioning into the Associate Director, Staff Engineer role.

Founded an enablement team that mapped end-to-end acquisition and affiliate API workflows across desktop, mainframe, and service boundaries. Architected a five-phase PII deletion remediation engine spanning more than 30 tables and identified seven distinct lending funnels through a tracking initiative.

Diagnosed a session-cookie overflow defect responsible for approximately 4% silent loss of digital loan applications during e-signing. Designed and executed a zero-incident blue/green migration to DynamoDB session storage.

Architected distributed telemetry across Rails systems, MuleSoft APIs, and IBM mainframe backends. Founded Geekfest@OMF and expanded an OpenTelemetry working group to more than 40 engineers while partnering with SRE, cybersecurity, and incident-command teams.

Modernized search and asynchronous messaging pipelines under live production traffic. Replaced legacy Sphinx search infrastructure with optimized MySQL full-text search and relational indexes, reducing external-cluster failure modes and operating footprint.

Led Ruby and Rails framework upgrades across core applications. Sequenced database migrations and deployment work to maintain zero downtime throughout platform modernization.

Improved performance and testability within a tightly coupled PHP and MySQL CRM backend. Replaced ad-hoc global data access with structured, cacheable query patterns that supported unit testing and sub-second query performance.

Hardened Ember.js automated test suites for core contact-management workflows. Created verification gates that enabled safer, non-breaking refactoring of legacy PHP systems.

Built high-throughput merchant analytics tools using Ruby and CouchDB to surface market insights for global sales operations. Redesigned technical onboarding curricula, standardized engineering practices, and shortened time-to-first-commit for more than 100 global engineering hires.

Owned enterprise assessment workflows in a high-concurrency environment. Led work focused on platform correctness, reliability, and security.

Supported the evolution of critical assessment systems while maintaining strong operational and security standards.

Owned API design and modernization strategy for a high-volume digital marketing platform. Led incremental migration efforts for legacy systems.

Balanced ongoing product delivery with architectural improvements intended to reduce technical risk and improve maintainability.

Engaged as a contractor by the founder to lead the open-source transition of the Coderwall developer reputation platform, a Y Combinator-backed network for software engineers.

Delivered security hardening, proprietary service extraction, infrastructure modernization, and community leadership. Became the top contributor to the open-source codebase, which reached 856 GitHub stars and 304 forks.
