Rust Backend Engineer
Rust backend engineer working on real-time trading and indexing pipelines on Solana.
- —Built a Solana blockchain indexer using Yellowstone gRPC to parse swaps and emit structured trade events in real time.
- —Built a real-time, event-driven notification platform by developing a Solana wallet indexer for on-chain token movements (replacing third-party webhooks), streaming events via Redpanda/Kafka, and fan-out processing through Rust workers into idempotent, preference-aware notifications delivered through PostgreSQL-backed in-app WebSocket updates and Firebase push.
- —Integrated Privy for wallet/auth flows to improve user onboarding and secure account linking between embedded/external wallets and backend notification/trading systems.
- —Built a real-time trading pipeline handling 10k+ trades/sec, generating multi-interval OHLC candles with sub-250ms latency.
- —Contributed to a high-throughput event-driven system, building downstream consumers that process asynchronous events and perform batched, idempotent writes to PostgreSQL.
- —Architected multi-level caching (in-memory + Redis) and scalable DB access, cutting DB load by 80%+ and API latency to under 50ms.
