Go backend engineer · AI developer tools

I build backend services and developer tools in Go. My current focus is coding-agent runtimes: tool execution, persistent sessions, and protocol compatibility. I also work with Python and am learning about model serving and inference performance.

A Go port of pi, a terminal coding-agent harness. The goal is to preserve upstream behavior while providing Go interfaces for agent workflows and sessions.

• Agent runtime: CLI entry points and an agent/tool loop for coding workflows.
• Session lifecycle: persistent session trees, continuation, and HTML export.
• Protocol interfaces: Go clients for JSONL RPC and the CBOR session protocol.
• Compatibility work: offline regression fixtures and a ledger of supported behavior and known differences.

In development · private source repository. Extensions, package management, parts of the terminal UI, and cloud authentication remain incomplete. Offline tests do not establish live-provider reliability.

Three merged contributions to the Gin ecosystem:

• Gin #4453 — integration-test reliability
  Replaced fixed startup sleeps with server-readiness checks using exponential backoff, and added tests for rebuilding the 404 middleware chain.
• Gin website #363 — upload example consistency
  Updated the Chinese single-file upload example to pass its declared destination variable to SaveUploadedFile.
• Gin website #359 — Chinese encoding documentation
  Translated the encoding guide, covering JSON library options, build tags, and CPU requirements.

Go backends: API design, concurrency, cancellation, and testable service boundaries.
AI developer tools: tool execution, session management, and failure handling.
Currently learning: model serving, latency/throughput measurement, and memory tradeoffs.

I value explicit design tradeoffs, reproducible tests, and documentation that makes a project easier to understand and run.
