Teaching Assistant

• Led the research, design sessions, technical discussions, and proof‑of‑concepts for a high‑concurrency transaction coordination subsystem that resolves race conditions and ordering conflicts under burst traffic, markedly improving correctness and sustained throughput reliability.
• Led the design and implementation of a centralized decorator‑based RPC dispatch and parameter validation framework that removed duplicated logic across handlers and simplified extensibility and maintenance.
• Eliminated 100% of query costs for intensive analytics and indexing workloads by reengineering the data access layer to source all read operations from a secondary, cost‑efficient service instead of the primary node, boosting performance and long‑term sustainability.
• Redesigned the `eth_sendRawTransaction` submission flow into an asynchronous processing pipeline, returning identifiers immediately after pre‑validation and cutting perceived client latency for high‑frequency integrations.
• Refactored
