Charles Schwab | Sr. Technical Project Manager
The Challenge
Schwab’s dual-codebase architecture created millions of dollars in technical debt, with legacy maintenance costs climbing 15% annually. This fragmentation imposed a "hidden tax" on innovation: every feature required double the development and testing, resulting in 35% slower time-to-market and redundant team overhead.
The Strategy
I led the transition to a "build once, deploy everywhere" model. By making responsiveness the default path, we eliminated team redundancy—consolidating independent web and mobile units into a single team. To protect business continuity, I utilized a Strangler Fig methodology, incrementally migrating legacy features into a unified responsive shell.
The Execution
After quantifying the debt to secure buy-in, I architected responsive infrastructure directly into the Everest Design System. We executed an incremental rollout, prioritizing high-traffic flows while measuring ROI via developer velocity. Finally, I established automated governance to prevent the re-introduction of device-specific codebases.
The Impact
We neutralized the $4M debt trajectory and eliminated the 20% annual overhead required for parallel platform maintenance. By merging codebases, we halved UI development cycles and unlocked the ability to ship critical tools to all users simultaneously on a stable, future-proof foundation.
