Distributed Systems Scaling: Designed and leading the team building a new distributed service to optimize and scale critical segments of query compilation and execution for petabyte-scale workloads.

Vectorized Expression Evaluation Frameowrk: Designed, implemented, and rolled out a new vectorized engine for expression evaluation, providing a high-level API that automates low-level vectorization and hardware optimizations for end-users.

High-Performance Data Representation: Led the Data Types team in designing a next-generation in-memory format for structured and semi-structured data, resulting in 10x–100x performance gains through optimized memory layout and vectorized compute.

Open Source & Standards: Represented Snowflake in the Apache Iceberg community to design the V3 Geometry and Geography specifications, while leading the internal team that implemented and shipped these types within the Snowflake engine.

Data Lake with the focus on Geospatial data processing and analytics

Metadata management system collecting metadata from multiple data repositories

Data catalog and Data Discovery tools

Tech Lead of Geospatial data ingestion engine applying spatial indexing on the fly, dynamically tailored to visualization workloads.

High-Scale Graph Processing: Built a dynamic routing engine that transformed raw geospatial data into a navigable pedestrian graph using custom Map-Reduce jobs.

Heuristic Ranking Models: Designed a multi-signal ranking system to score walking tours, integrating geospatial constraints with metadata (e.g., photo density) to optimize for "scenic" paths.

Latency-Critical APIs: Implemented optimized TSP solvers (Branch and Bound) and A* search variants to provide real-time, location-aware route generation via public-facing APIs.

Impact: Engineered the "City Walks" system, recognized for innovation in Apple’s iPad marketing campaign.
