Byzantine-fault-tolerant distributed file system with miner-client architecture, gossip-based membership, and proof-of-work consensus.
Demonstrates:
Fast, lightweight vector search engine with HNSW indexing, SQL-based filtering, and payload storage. Three modes: embedded (in-process), standalone (server), and clustered (Raft-replicated across nodes).
Demonstrates:
High-performance storage engine based on log-structured merge trees with crash-safe WAL recovery and tunable compaction.
Demonstrates:
Learned LSM-tree index leveraging linear key relationships for ~33% YCSB read improvement over RadixSpline. Research collaboration with Dr. Song Jiang.
Demonstrates:
Microservice distributed transactions using SAGA orchestration over RabbitMQ with MassTransit routing.
Demonstrates:
Production data-migration system from a Cefalo client engagement: zero-downtime DynamoDB → Aurora PostgreSQL migration of 40M+ records using Spring Batch with segmented scans, validation, and incremental sync.
Demonstrates:
Rust ORM that auto-generates CRUD methods, DTOs, and pagination helpers via Entity derive macros.
Demonstrates:
LR parser implementation with parse tables and parse trees for mathematical expressions.
Demonstrates:
Document summarization tool combining extractive and abstractive techniques for long-form text.
Demonstrates:
Content-preserving PDF document transformer for manipulating PDF files while maintaining document integrity.
