About this gig
I'm a developer specializing in the Claude ecosystem not generic AI tools, just Claude. Claude Code, Claude Cowork, the Claude API, and MCP integrations are what I do every day.
Most setups underperform because the model gets the blame when the architecture is the real problem. I focus on the architecture.
What I build and set up
- Claude Code installed and configured for your stack (Mac, Windows, Linux)
- MCP servers connecting Claude to your database, files, Slack, Gmail, and internal tools
- Claude API integration into your existing app, CRM, or backend
- Claude Cowork configured for autonomous file handling and scheduled work
- Claude agents that reason, decide, and act on real business tasks
- Custom system prompts that make Claude behave the way your business actually needs
- Bug fixing on existing Claude implementations that aren't behaving correctly
Tech I work with
Claude Code · MCP (Model Context Protocol) · Claude API · Next.js · React · TypeScript · Node.js · Supabase · PostgreSQL · n8n · Vercel · Git
Message me your use case before ordering. A 10-minute scoping conversation saves both of us hours of revisions later.

Hi, I'm Nathaniel a full-stack developer building modern AI-powered web apps and MVPs for founders who want to launch fast without losing months and thousands of dollars on traditional development.
I work primarily with the new generation of AI development platforms: Lovable, Bolt.new, Cursor, v0, Supabase, and Replit.
These tools let me take an idea from sketch to a deployed, working product in days instead of months while still delivering clean code you actually own and can scale later.

FAQ
What is Claude Code and how is it different from ChatGPT?
Claude Code is Anthropic's AI coding agent that reads your actual codebase, writes features, and fixes bugs directly from your terminal. ChatGPT is a chat window where you paste code. Claude Code lives inside your project.
What is MCP and why does it matter?
MCP (Model Context Protocol) lets Claude access your live tools — your database, Slack, Gmail, Drive, CRM, internal APIs. Without MCP, Claude only knows what you paste in. With MCP, Claude queries real data and takes real actions across your systems.
What is Claude Cowork?
Claude Cowork is Anthropic's desktop agent that works autonomously on your computer — handles files, runs scheduled tasks, delivers finished work. I configure it for your specific workflow.
Which Claude model is right for my project?
Haiku for fast high-volume tasks. Sonnet for the best balance of speed and intelligence (right for most projects). Opus for complex reasoning. I recommend the exact model for your use case before we start.
Can you work on my existing project?
Yes. I can jump into an existing codebase, understand the architecture, and start contributing.
Do I own everything you build?
Yes. Full source code, full documentation, all credentials and config. Nothing locked to me.
Do you offer support after delivery?
Yes, included in Standard and Premium for 7 days. Longer-term maintenance available as a custom offer.
