01 / Overview
At Poshmark, I lead frontend engineering initiatives across the web platform, focusing on bridging the gap between high-fidelity product discovery and technical platform excellence. My work spans from consumer-facing live commerce to core SSR infrastructure and security.
Working within a massive social marketplace requires a delicate balance of rapid feature shipping and long-term architectural stability. I have been instrumental in modernizing our frontend stack, significantly improving web performance, and strengthening the security posture of our global web surfaces.
02 / Product Areas
Marketplace & Redesign
Led frontend work for the redesigned marketplace discovery journeys. Focused on creating a cohesive design system and responsive UI that scales across thousands of brand and category surfaces.
Discovery Flow
Live Commerce (Posh Shows)
Built real-time web experiences for Posh Shows, including live auctions, chat, and product trays, helping transition social interactions into seamless commerce workflows.
LIVE
Real-time UX
Seller Growth & Ads
Contributed to Promoted Closet and seller-growth surfaces, building high-performance analytics dashboards and ad-management tools for our seller community.
Performance Metrics
AI & Search Initiatives
Collaborated on next-generation marketplace initiatives focused on discovery and search relevance, integrating AI-driven insights into the core shopper experience.
SSR Architecture
03 / Architecture Themes
Vue 2 to Vue 3 Migration
Spearheaded the migration of complex legacy surfaces to Vue 3 and Composition API. This improved developer velocity by 30% and enabled better code sharing and type safety across our monorepo.
SSR Platform Modernization
Managed the incremental upgrade of our Node.js runtime from v14 to v22, optimizing memory consumption and ensuring compatibility with modern ESM-based dependencies.
04 / Performance Work
Optimization is at the core of my engineering philosophy. By optimizing critical path rendering, tree-shaking, and implementing efficient caching strategies, we achieved:
p95 Page Load Time
-40%
p99 Interaction Latency
-28%
Local Build/HMR Time
-33%
05 / Security / CSP
Partnered with the Security team to implement a strict Content Security Policy (CSP) across all web domains. This involved auditing hundreds of third-party scripts, refactoring inline event handlers, and establishing a secure-by-default development workflow.

07 / How I Work
Technical Planning
Every feature starts with a RFC or Technical Design Doc. I translate product specs into implementation plans that account for edge cases and performance.
Scalable Architecture
I prioritize building reusable components and shared libraries that empower other engineers to work faster and more consistently.
Collaborative Spirit
Bridging silos between Product, Design, and Backend. I believe the best engineering happens when we understand the 'why' behind the 'what'.
AI-Assisted Efficiency
Leveraging modern AI tools to accelerate boilerplate and unit tests, while maintaining a rigorous human-led planning and review process.
08 / What I Learned
Working at Poshmark has taught me that at 130M+ users, every millisecond and every pixel matters. I learned how to navigate massive codebases, drive consensus across multi-functional teams, and the importance of observability in production. Above all, I've seen how strong technical foundations directly enable product innovation.
