Software Engineer E5 (Team Lead) - WHATFIX

(2023-02 - 2026-06)

• Engineering Leadership: Led a cross-functional squad of 2-4 engineers, driving the planning, requirements gathering, and task execution. Mentored team members, managed career growth plans, and removed blockers to accelerate delivery of high-scale web architecture and AI-driven automation initiatives.
• Strategic Revenue Growth (Custom Variables): Architected and led the development of a feature called Custom Variables engine that allows for the dynamic capture and injection of user-specific data into DAP (Digital Adoption Platform) workflows. This feature was the primary catalyst in securing an 8+ unit displacement deal, contributing $3M+ in net ARR.
• Performance & Refactoring Initiatives: Led a large-scale refactoring initiative transforming a monolithic legacy GWT/React hybrid architecture into a high-performance, modular React-based ecosystem. Optimized load times and responsiveness by implementing strategic code-splitting, lazy-loading, and aggressive bundle size optimization. Achieved measurable improvements in Core Web Vitals, reduced Time to Interactive (TTI), and minimized latency through efficient API contract design. Awarded Spot Aw
• AI Knowledge Engineering: Independently developed a POC leveraging RAG (Retrieval-Augmented Generation) by scraping Slack channels for Customer Success stories and PM insights. Created an AI-indexed repository that maps historical problem-solving patterns to new problem statements, providing automated, context-aware DAP solutions.
• AI Agent Repository: Developed a centralized repository of Claude sub-agents tailored for the engineering squad, automating the creation of technical design documents and standardized implementation plans.
• Quality & Accessibility Excellence: IAAP Certified specialist driving company-wide WCAG 2.1 AA accessibility compliance across the design system, combined with a robust quality culture achieving 100% automated test coverage (450+ test cases). Awarded Accessibility Champion (2025) and OKR Rockstar (2024).
• Translation Ecosystem & Orchestration: Engineered a centralized platform for content authors to manage localization workflows; integrated Microsoft Azure Translation API for automated translation and architected a flexible configuration layer allowing users to plug in and manage custom translation tools.
