You will get a focused web or API bug fix with verification
Project details
You will get one focused web or API bug fixed within a clearly agreed scope. I will reproduce the issue, identify the root cause, implement one contained fix, run relevant existing checks, and provide a concise written handoff with verification evidence. This service is suitable for Java/Spring, TypeScript/JavaScript, REST APIs, SQL, Vue/React, Node.js, and Cloudflare Worker issues. It covers one reproducible bug and up to two engineering hours after the project runs in the provided environment. Multiple unrelated issues, redesigns, legacy rewrites, production data repair, and open-ended maintenance are outside this package.

About Le
Full-Stack & AI Application Developer | Java, TypeScript, Cloudflare
Shijiazhuang, China - 6:02 pm local time
I am best suited to focused work that needs a dependable outcome: fixing a reproducible bug, adding a small API or full-stack feature, stabilizing a deployment, or integrating an AI capability with clear operational boundaries.
What I can help with:
• Java and Spring backend fixes, concurrency and transaction issues
• TypeScript, Node.js, Vue, and React application work
• REST APIs, webhooks, SQL, D1, and integration debugging
• Cloudflare Workers, Docker Compose, Ubuntu VPS, and Caddy deployments
• AI/RAG and LLM integrations with deterministic validation and fallback behavior
• Automated tests, browser verification, deployment checks, and written handoff
I work primarily through written English, requirement checklists, asynchronous progress updates, and screen-recorded demonstrations. Before starting, I confirm the exact deliverable, acceptance criteria, required access, and what is outside the contract.
