Hire a Claude Code Developer: Claude AI Expert for SaaS and CRM

What does a Claude Code developer do for your project?

A Claude Code developer turns your idea into working software by directing AI coding agents the way a lead engineer directs a team. I write the spec, prepare the repository and its rules, hand small tasks to Claude Code and OpenAI Codex, and review, test and merge what they produce. You get the output of several developers working in parallel, with one experienced person answerable for every line.

That last part is what separates engineering with AI from prompting until something appears to work. An agent can write a login form in a minute; it can also store passwords badly, skip a permission check or quietly change a file it was not asked to touch. Thirteen years of building SaaS products, CRMs, WHMCS modules and hosting systems is what lets me spot those mistakes in review and design the work so they are rare.

What can I build for you with Claude Code and Codex?

Anything I could build by hand, I now build faster with agents. These are the projects I take on most:

If you need a CRM quickly, the custom CRM in 7 days offer is this same method applied to a fixed scope.

How much faster is development with AI agents?

Much faster on the parts that are code, and no faster on the parts that are decisions. In my own work, a project I planned as six months before AI agents now ships in about 7 days when it builds on code I already have, and a roadmap I once quoted as a year takes about 15 days. Three things produce that speed:

• Base code from 13+ years of projects. Authentication, roles, billing, imports, PDF documents, payment webhooks and admin panels already exist and are tested, so agents extend them instead of inventing them.
• Parallel agents. Several tasks run at once in separate branches, while I plan the next ones and review the finished ones.
• Automated tests. Every change is checked in minutes, so speed does not turn into regressions.

What does not get faster: agreeing on the scope, waiting for outside approvals such as payment provider checks or app store review, cleaning years of messy data, and your team learning the new tool. I plan those into the date instead of hiding them.

How do you run Claude Code on a client project?

I run it as a controlled process, not a chat. The steps are the same on every project:

1. Write the spec: users, screens, data model, roles and the acceptance tests the finished work must pass.
2. Set the rules: a CLAUDE.md file for Claude Code and an AGENTS.md file for Codex describe the architecture, conventions, test commands and forbidden actions.
3. Plan before editing: the agent proposes a plan for each task, and I correct it before it writes code.
4. Work in branches: each task runs in its own branch or worktree, so parallel agents never overwrite each other.
5. Gate every change: hooks run the formatter and tests automatically, and nothing merges until the tests pass and I have reviewed the diff.
6. Connect tools carefully: where an agent needs documentation or a database, I connect it through an MCP server with read-only or test-only access.

How do you keep AI-written code secure and maintainable?

By treating the agent as a fast junior developer whose work always gets reviewed. Secrets and production credentials never enter a prompt or the repository. Agents get the narrowest permissions that let them do the task, and commands that delete data or touch production need my approval. Dependencies are checked before they are added. The code follows one architecture written down in the rules files, so it stays readable to the next developer, human or AI.

Can you fix a vibe-coded app that now breaks?

Yes, and it is a growing part of my work. Vibe-coded apps, generated quickly by prompting without a spec, often share the same problems: no tests, secrets in the code, missing permission checks, duplicated logic and a database that does not match the screens. I start with a written audit of what is safe, what is broken and what must be rebuilt, then add tests around the parts we keep and fix them in priority order. Sometimes a clean rebuild on my base code is faster, and I say so.

Can you set up Claude Code or Codex for our own developers?

Yes. For teams that want to keep building themselves, I set up the rules files, test and lint hooks, MCP connections and a review routine for your repository, then work alongside your developers on a real feature so the method sticks. For ongoing help after that, the monthly developer retainer keeps me available without a new quote for each request.
