Profile
Software engineer specializing in Go and Rust with a focus on
blockchain data infrastructure and high-performance systems.
Built a Solana snapshot parser achieving 850 MB/s throughput
using zero-copy parsing and parallel deserialization across
100GB+ of on-chain state data. Experienced in designing
streaming data pipelines, optimizing system performance for low
latency, and working with chain-level data parsing and state
inspection. Exploring EVM internals and DeFi protocol
architecture.

Projects
Solana Snapshot Parser
In Development github.com/yottaes/ssp High-performance CLI tool for streaming, parsing, and
analyzing Solana validator snapshots (~100GB+) without
storing them on disk. Architecture designed as a
generalizable chain-state processing pipeline applicable to
any blockchain with account-model state.
- Achieved ~850 MB/s throughput (6.1x over single-threaded
baseline) using zero-copy deserialization (bytemuck) and
parallel processing via crossbeam channels
- Streams snapshots directly from 300+ RPC nodes via HTTP
— discovers fastest source using async probing (tokio).
Zero local disk usage
- Pipeline: RPC Discovery → HTTP Stream → zstd decompress
→ tar unpack → AppendVec parse → Parquet → DuckDB.
Supports owner/pubkey/hash filters
- Outputs structured on-chain data to Parquet/DuckDB for
analytical queries — similar approach to how DEX
aggregators index liquidity pool state for routing
