3+ years building backend, fintech, and blockchain infrastructure. My current focus is Rust systems engineering — async/concurrent services, networking, distributed systems, and open-source development.
Rust · Tokio · Tonic/gRPC · Qdrant · Rig
A streaming RAG backend for document ingestion, semantic retrieval, and grounded LLM responses over a strongly typed gRPC API. Async streaming with Tokio keeps tokens flowing to clients under concurrent load, while Qdrant handles vector search and Rig wires the model calls.
Rust · Async · Ethereum · Solana · BSC
Merchant payment infrastructure spanning Ethereum, Solana, and BSC: per-merchant wallet/address generation, on-chain transaction monitoring, webhook/event processing, and settlement workflows. Async Rust keeps confirmation watching and webhook delivery responsive across chains.
Go · Kubernetes · Ansible · Ethereum
Automated provisioning for private Ethereum networks: a Go control layer plus Ansible drives node and validator lifecycle on Kubernetes — bootstrapping, scaling, and teardown — with Prometheus/Grafana observability over TPS, block latency, and node health.
Python · FastAPI · PostgreSQL · Redis · MT5
Production brokerage backend bridging a Windows MetaTrader 5 Manager API to Linux FastAPI services: real-time trade synchronization, a multi-level IB commission engine, and wallet/fund reconciliation between MT5 and the CRM ledger.

Rust · Ethereum execution client · Async
A blocking payload-bodies lookup was running on the async runtime and stalling the engine API. I refactored `get_payload_bodies_by_hash_with` to be `async`, offloading the blocking I/O onto `spawn_blocking` so the request no longer occupies an executor thread.

Rust · Ethereum · JSON-RPC / WebSocket
The pubsub frontend was splitting a `RequestPacket::Batch` into individual requests, so a JSON-RPC batch went out as many WebSocket messages instead of one array. I preserved the batch through the pubsub layer so WS/IPC transports send a single wire packet while still tracking each request by its JSON-RPC id.

Rust · QUIC · Low-level correctness
The i686 build failed because the code transmuted `0u128` into a `std::time::Instant` — but `Instant` is 96 bits there, not 128. I replaced the size-assuming transmute with `mem::zeroed::<Instant>()` so the zero value is constructed portably across targets.

Rust · AI infrastructure · Async lifetimes
Manual RMCP tool registration stores a cloned `ServerSink` that doesn't own the connection, so dropping the `RunningService` silently tore down the transport and made registered tools stop responding. I traced the ownership model and documented the lifetime requirement callers must uphold.

An experiment tracing a Rust thread down to the native OS thread — how spawning maps to the kernel, stacks, scheduling, and system-level behavior.
A deep walkthrough of qrag-rust — chunking, embeddings, Qdrant vector search, and grounded answers streamed over a Tonic gRPC API.
A blueprint for reliable multi-agent AI: the task DAG, the validator as a trust boundary, orchestrator-mediated communication, and failure handling.
I'm interested in Rust backend, systems engineering, distributed systems, infrastructure, and open-source opportunities.
