ABOUT

Both ends of the chain

A full-stack developer and designer, I like to understand a need, design the interface, then build it. Seven roles across startups, ERP and consulting taught me to ship fast and clean, within agile teams.

Optimized the smart assistant: end-to-end analysis, spotted a data-architecture issue and migrated from a relational database to a vector database (Milvus) — response time cut in half. Built role and access management for external providers, technical screens, and documentation adopted as an internal reference.
