5+ years building web & mobile platforms at scale.

I care about the parts of software people feel: how fast it loads, how it responds to a tap, how little it gets in the way. I build both the features people use and the tools that help teams ship them. Currently at BlackRock; previously TikTok Shop and Shopee.

    • Own the frontend for Campaigns: tools that let central offices roll out investment strategies across their entire book of business and track advisor adoption and portfolio impact.
    • Built a custom Vite plugin for seamless development across all client environments, eliminating environment drift.
    • Review frontend designs and code across teams, from state management to component architecture, helping keep patterns consistent.
    • Built an AI smart filter that helps advisors filter portfolios faster, using Spring AI and a RAG workflow, with Langfuse observability and ground-truth testing to refine prompts and balance token cost against model choice.

    • Frontend owner for Creator Analytics serving 1M weekly users across the UK, US and SEA on mobile and web; two M+ (Exceeds Expectations) grades.

    • Built CI/CD pipelines for the Shopee app’s React Native platform, dramatically speeding up deploys for core product pages.
