Build. Create. Explore.
AI Engineer, Data Engineer, Product Builder, Photographer and Lifelong Learner.
I build systems to understand the world, and I explore the world to find what’s worth building.
Structure. Where a question becomes a system — code, architecture, a working thing with logic underneath.
Expression. Where the system or the journey becomes a story someone else can feel.
Input. New places, new problems, new domains — where curiosity gets fed and questions get found.

Featured Work
Real-time Feature Store
Cut model-serving latency from 400ms to 30ms by rebuilding the feature pipeline on a streaming architecture.

Personal Knowledge Assistant
Every static personal site says 'ask me anything' but doesn't actually let you. I wanted a real interface for that, without committing to a fragile chatbot before I had content worth retrieving over.
TYPESCRIPT · NEXT.JS · VECTOR DB (PLANNED)
Retrieval Benchmarking Harness
Comparing chunking and embedding strategies on small, messy real-world corpora, where most published RAG benchmarks assume clean, large-scale datasets that don't resemble a personal knowledge base.
