I will fix one go backend bug and add regression tests
Chen Cheems
About this gig
I will fix one agreed, reproducible Go backend bug. Please confirm scope before ordering.
US$75, 3-day delivery, and 1 revision within the original scope. Delivery includes a minimal patch, before-and-after regression tests, and a concise handoff with reproduction commands, actual results, environment details, and untested limitations.
Provide authorized source code or a minimal reproduction; exact steps and expected versus actual behavior; redacted logs; Go version, dependency manifests, local setup/test commands, safe inputs, acceptance criteria, and access restrictions. Production credentials are not required.
Excluded: production deployment, infrastructure changes, broad refactoring, additional bugs or features, incident response, and ongoing maintenance. The revision covers the original bug and agreed acceptance checks.
Synthetic portfolio demo: the same 12 tests had 3 failures before a one-line fix and all passed afterward (Go 1.25.5, macOS arm64). This is not client work; the 12-test count describes only this demo. An order receives tests relevant to its agreed bug.

Software engineer with a background at Tencent and Megvii. I build backends, AI agent integrations and Web3 tools using Go, Rust, TypeScript, Java, C++ and Python. Open-source work: eth-mcp (Ethereum queries and swap simulation, not live trading), Anvil (alpha order-book/matching), Moment (Go/React), and PR Checker (GitHub Action). I contribute to Open Design's agent runtime and CLI BYOK integration. I offer APIs, MCP servers, automation, prototypes, testing, performance tuning and quantitative backtesting. These projects are open-source work, not paid client results.
FAQ
What does the package and revision cover?
One agreed, reproducible Go backend bug: a minimal patch, relevant regression tests and handoff notes. The included revision addresses the original bug and agreed acceptance checks. New bugs or features require a separate scope agreement.
What should I provide before ordering?
Confirm scope first. Provide authorized source or a minimal reproduction, exact steps and expected/actual behavior, redacted logs, Go version, dependency manifests, local setup/test commands, safe inputs, acceptance criteria and access restrictions. Production credentials are not required.
