About

I design and build low-latency, high-availability distributed systems for large-scale data and AI workloads — the kind that have to hold up under real production pressure, not just work in theory. At Oracle, I build vector database capabilities into Oracle DB — architecting distributed HNSW and IVF-based ANN search across multi-million-vector embeddings, and partitioning GB-scale HNSW graphs for horizontal scale. In parallel, I work deep in the transaction layer, strengthening concurrency control and failure recovery for systems that can't afford to go down. My work sits at the intersection of: Distributed systems (consistency, fault tolerance, concurrency control) Database internals (indexing, query execution, storage & transaction engines) AI infrastructure (vector search, semantic retrieval, GenAI systems at scale) I've contributed to: Designing distributed HNSW & IVF indexing pipelines for low-latency, high-accuracy vector search at scale Improving distributed transaction reliability (concurrency control, failure recovery, Flashback Undo) under heavy production load Building a GenAI-powered chatbot automating RDBMS health and sign-off workflows — while mentoring a team of 3 engineers I gravitate toward problems where scale, latency, and correctness all have to hold at once — and I don't consider a system done until it does.
