I help developers, freelancers, and teams get real results from Claude Code instead of struggling with it on their own. Many people install an AI coding tool, try a few prompts, and walk away disappointed. The difference between frustration and a major productivity boost usually comes down to setup, workflow, and knowing how to guide the tool effectively. That is exactly what I teach and configure. My consulting services include installing and configuring Claude Code for your environment, writing CLAUDE.md files that give the assistant the right context about your project, setting up MCP integrations that connect it to your tools and data sources, and creating reusable prompts and workflows for your most common tasks. I also help teams define sensible permissions and review habits so AI-generated code stays safe, consistent, and high quality. Training is hands-on and practical. In one-on-one onboarding sessions, we work directly in your own codebase, so you learn by solving real problems rather than watching abstract demos. I cover how to plan features before coding, how to break large tasks into smaller steps, how to debug with AI assistance, and how to review output critically so mistakes are caught early. Beginners and experienced engineers alike leave with confidence and a repeatable process. Every engagement includes a written playbook tailored to your project, covering setup steps, prompting patterns, and best practices your team can share and reuse. I also offer follow-up support for questions that come up after the session. Whether you are a solo developer, a growing startup, or a team exploring AI-assisted coding for the first time, I can shorten the learning curve and help you ship better software faster.

When something breaks and you cannot figure out why, I step in to find the root cause and fix it properly. I specialize in diagnosing stubborn bugs, performance bottlenecks, failed deployments, and strange behavior that only appears in production. Using Claude Code alongside my own hands-on debugging experience, I can trace problems through large codebases quickly, even when the code is unfamiliar and the documentation is missing. My process is simple and transparent. First, I reproduce the issue and gather context, including error logs, stack traces, and recent changes. Next, I use Claude Code to explore the relevant files, follow the data flow, and form hypotheses about what is going wrong. Then I verify each hypothesis with real tests rather than guesses, apply a targeted fix, and confirm that nothing else was affected. Finally, I write a clear explanation of what caused the problem and how to prevent it from happening again. I have helped startups and small businesses resolve issues such as broken API connections, slow database queries, memory leaks, authentication failures, CORS and environment configuration errors, build pipeline problems, and bugs introduced by rushed updates. I work with JavaScript, TypeScript, Python, React, Node.js, and common cloud platforms, and I am comfortable jumping into projects built by other developers. Clients appreciate that I respond quickly, communicate clearly, and never hide behind jargon. You will always know what I am investigating, what I found, and what I changed. Every fix comes with a short summary written in plain language, so even non-technical founders understand what happened. If your project is stuck, your launch date is close, or your team has been chasing the same bug for days, send me a message and I will help you get unstuck.
