Frontend Architecture lead (React platform migration) at Concord

April 1, 2026 - Present

Led the evolution of the company's next-generation React platform by driving architectural decisions balancing rapid product delivery with long-term engineering sustainability. Led the migration from Ember.js to the next-generation React platform. Designed modular architecture and reusable abstractions for long-term growth, continuously reduced technical debt through incremental architectural improvements, and guided engineering trade-offs with Product and Design teams.

Improved Product Performance & Reliability at Concord

April 1, 2026 - Present

Delivered 3× reduction in Largest Contentful Paint (LCP) on the platform's highest-traffic pages by embedding performance into shared frontend foundations rather than optimizing pages individually. Integrated virtualization, deferred rendering and intelligent data loading into reusable platform components, eliminating unnecessary rendering and network activity across complex interfaces. Enabled new features to inherit high-performance rendering patterns by default. Provided production hotfixes and resolved performance issues to improve platform stability.

Scale Frontend Delivery (Design System engineering platform) at Concord

April 1, 2026 - Present

Owned and evolved the Design System supporting a frontend organization of 5–8 engineers. Transformed the Design System into a reusable engineering platform powering ~80% of data-intensive pages across a next-generation React application. Delivered 50–70% faster feature delivery by building a configurable DataGrid framework with data fetching, virtualization, lazy rendering and common interactions, and by embedding accessibility, performance and consistent UX into shared engineering foundations. Standardized reusable abstractions across applications and shared libraries.

Scale Engineer (Frontend Engineering & AI-assisted development) at Concord

April 1, 2026 - Present

Drove a three-month AI productivity initiative selected by engineering leadership, standardizing Cursor, Claude Code and MCP servers across the frontend team. Built AI-ready project context through documentation, coding standards and reusable agent skills. Integrated AI-assisted implementation workflows and automated GitHub PR reviews to enable collaboration between developers and coding agents while maintaining engineering quality. Achieved 3× frontend engineering throughput by designing and rolling out the organization's AI-assisted development system.
