• Core Ownership: Fully owned frontend engineering, production stability, and roadmap delivery for the core Data Pod ecosystem spanning 7 high-traffic web applications.
• High-Density Data Optimization: Engineered highly responsive dashboards handling massive real-time datasets by implementing UI virtualization and optimized input debouncing, eliminating UI lag during heavy filtering operations.
• Main-Thread Optimization: Resolved critical browser main-thread freezes caused by heavy client-side document generation. Refactored the rendering pipeline using strict data-capping constraints and chunked processing to ensure smooth multi-page execution.
• Bundle Optimization: Reduced initial bundle size by ~30% via route-based code-splitting, lazy loading, and deep Webpack/Vite tree-shaking analysis.
• Engineering Governance: Configured automated pre-commit safeguards using Husky hooks, strict ESLint policies, and Jenkins CI/CD pipelines to enforce code quality and eliminate regression risks.
• Tooling & Mentorship: Built a Slack-integrated release bot automating production deployment summaries. Acted as an onboarding buddy, mentoring incoming engineers and integrating AI-assisted workflows into code-review processes.

Software Engineer at Esko (2021-01 – 2025-03)

• Architectural Decoupling: Engineered a standalone React frontend module embedded within Adobe CEP (Common Extensibility Platform) plugin panels. Configured custom Webpack compilation to output optimized, isolated client bundles compatible with embedded Chromium containers.
• Business Impact: Implemented a Node.js reverse proxy local integration layer to decouple the release cycle from the parent monolith, enabling a standalone licensing model that drove a 30% product adoption increase.
• Runtime Performance: Achieved a 25% improvement in UX performance metrics by profiling memory/heap structures via Chrome DevTools, eliminating expensive nested React re-renders and deduplicating redundant API payloads.
• Agile Leadership: Served as Scrum Master for an engineering pod, overcoming technical friction blocks to boost sprint velocity by 30% across 8+ major feature rollouts.
