• Co-architected Mobile JS Core, the central JS runtime powering DAP content delivery across Android & iOS. Covering command bridge, observer framework, analytics pipeline, and screen hierarchy filtering. Sole frontend owner across 3 platforms for 6 months, managing features, escalations, and production issues. • Engineered Self-Hosting end-to-end (config decompression, segmented routing, functional restrictions, state preservation), enabling air-gapped SDK deployments. Drove adoption by 5 enterprise clients, unlocking banking and finance verticals blocked by data residency constraints. • Designed the Custom Selector Framework with Shadow DOM support, enabling onboarding of enterprise client- TruHome and opening the vertical for all Shadow DOM-based clients. • Co-designed a real-time bidirectional device mirroring system streaming mobile screen hierarchies over WebSockets as interactive HTML, relaying desktop interactions back to mobile, enabling remote content authoring. • Redesigned Observer Architecture: rationalized events, added INFO/DEBUG separation, traceIds for end-to-end tracing, and cyclic change-detection to suppress redundant uploads. Reduced log volume by 10x, resolving a recurring server overload incident. • Revamped webview JS injection to a single batched call, eliminating 90% of redundant calls and multiple race conditions, improving rendering performance across webview-heavy clients. • Architected a per-minute Observer Alerts system with Slack alerting on screen hierarchy metrics, proactively preventing ANRs before production. • Built a Jenkins pipeline to auto-scan package-lock files and migrate NPM to JFrog, adopted company-wide, replacing a manual process as part of an org-wide security mandate. • Hardened platform security: migrated auth to HttpOnly cookies with CSRF tokens; remediated XSS via input sanitization and SVG restrictions; added X-Frame-Options: SAMEORIGIN against clickjacking.
