Experience

1. CompatibL

   Lead Software Engineer / Team Lead

   Dec 2010 - Present

   • Embedded full-time in customer environments on long-running engagements for Bank of America, Charles Schwab, the European Investment Bank and other Tier-1 institutions — owning architecture, design, implementation, cloud deployment and production support inside the client’s own systems, including on-call incident response and root-cause analysis against agreed SLAs.
   • Led cross-functional teams of up to nine engineers across two concurrent client engagements, partnering with Bank of America’s architecture team to define solution architecture and guide technical decision-making.
   • Drove the launch of new financial management software that generated 20% revenue growth within one year; established CI/CD pipelines, TDD and code-review standards and a controlled release strategy that were reused across client environments, lifting release velocity by over 30% while raising code coverage and cutting QA-reported defects; mentored 4+ engineers.

   Selected client engagements

   • Curve, Volatility & Bond Marking Platform — Bank of America

     (Lead Developer) — Developed a generic React and OpenFin UI to replace manual Excel tools and inconsistent legacy libraries across multiple trading desks. Built frontend microservices over a Python pricing backend. Migrated system in backward compatible increments, decreasing UI latency 20x and pricing latency from 500ms to 35ms.

   • Expense & Vendor Management Platforms — Charles Schwab

     (Team Lead) — End-to-end cloud expense system (invoicing, contractual fees and OERs, budgeting, forecasting and regulatory reporting) plus a vendor oversight platform. Asked for a daily exception report, established the real need was catching exceptions before payment ran and delivered automated monitoring instead, removing the manual review. Delivered the bank’s first multi-cloud system. AFTAs Best IT Team 2017, 2018 and 2019.

   • CompatibL Risk Platform

     (Team Lead) — Cloud-based trading and risk platform for market and counterparty credit risk, initial margin and regulatory capital. Led development of a product used by multiple banks and ran the security analysis for its cloud migration. Winner, Risk.net Market Technology Awards — XVA Calculation Product of the Year.

   • CDS & Bond Trading Platform — Bank of America

     (Lead Developer) — Client-server desktop platform for credit traders: securities pricing, Runs distribution, intraday risk management, P&L estimation, TRACE monitoring and trade-history search across bonds and credit default swaps. The bank’s strategic credit trading automation solution, used by 400+ users globally; integrated AMPS real-time messaging.

   • EibRiskALM — European Investment Bank

     (Team Lead) — Client scoped a bespoke monitoring application; establishing what they actually needed to see showed the existing CompatibL Platform could deliver it through configuration and a thin extension, avoiding a new codebase — giving the Credit Risk team market trigger and alert monitoring across legacy credit products.
