AI and backend engineer building reliable agents, high-concurrency APIs, and trading systems.
I help teams turn ambiguous requirements, unstable integrations, and prototype AI flows into tested services with explicit safety boundaries, observability, and practical runbooks. I spent nearly four years at ByteDance working on cloud authorization, TikTok social systems, recommendation integrations, and transactionally consistent B2B services. My current work focuses on gateway, API, and reliability infrastructure for high-concurrency trading systems.
- AI-agent backends — multi-step tool calling, strict schemas, RAG integrations, tracing, cost controls, and failure guardrails.
- Reliable Go/Python APIs — idempotency, WebSockets, concurrency, retries, circuit breakers, rate limits, and production debugging.
- Trading automation — TradingView webhooks, exchange or broker adapters, paper/testnet execution, reconciliation boundaries, and risk controls.
- Clear handoff — automated tests, Docker-based local setup, architecture notes, monitoring, and operator runbooks.
| Project | Client-relevant proof | Verification |
|---|---|---|
| AgentOps Studio | Auditable OpenAI/DeepSeek tool loops, tenant-scoped traces, cost and repetition guards, FastAPI/PostgreSQL, and a Next.js console |  80%+ backend coverage gate |
| Northstar API Reliability Lab | Duplicate suppression, overload shedding, bounded dependency failure, WebSocket replay, Prometheus, and Grafana |  Go race detector + replayable scenarios |
| PineFlow v6 | TradingView-to-broker automation with validated webhooks, idempotency, a Decimal position ledger, and paper/testnet adapters |  Python and TypeScript tests |
- SoDEX Go SDK — Nova 0.8.0 signatures: merged EIP-712 signing support for permissioned API keys, builder fees, and Spot/Perps TWAP requests, with testnet and hash-parity verification.
- SoDEX Go SDK — revoke API key signing: merged request types and signing helpers for engine-specific API-key revocation, including signature recovery and domain-separation tests.
For Web3 work, see the ERC-4337 Treasury Smart Account, bonded optimistic oracle, and oracle-guarded Dutch auction. These are educational testnet reference implementations and have not undergone an independent security audit.
All portfolio data is synthetic or testnet-only; the repositories include reproducible setup, tests, and explicit limitations.
