You will get Claude Code MVP web app Claude AI API Next.js Supabase Claude Sonnet 3.6
Project details
You have a product idea, but turning it into a working SaaS with AI inside is where most builds stall. Either the app works but the AI is unreliable, or the AI works but the product cannot scale. This Claude Code Web App development service handles both from the start.
I design and build a complete MVP and AI powered web application using Next.js, React, and PostgreSQL, with Claude API integration built properly into the product. That means consistent outputs across users, structured prompts through SKILL.md and CLAUDE.md, and a system that can grow beyond a prototype.
• Product architecture document with data flow and system design
• Working web application with Claude integration
• User authentication and multi-tenant setup
• Third-party API integrations (e.g. Stripe, Shopify, Google)
• GitHub repo, documentation, and Loom walkthrough
This system is built for founders who want to launch a real product, not just test ideas in isolation, and is best for SaaS tools, internal AI platforms, and customer-facing apps.
Tell me what your product should do and what stage you are at; The idea, prototype, or rebuild.

Job Success
Benin City, Nigeria - 11:31 am local time
As a Claude Code Developer, I build production AI systems: AI agents, automated manual workflows, and coach the individual and teams operating them.
The work I build covers custom MCP server development, SKILL.md file creation, multi-agent orchestration, CLAUDE.md architecture, subagent configuration, RAG pipelines built on your own documents, and automation pipelines connected to n8n, Make com, GoHighLevel, HubSpot, Supabase and other platforms with APIs. Every pipeline uses human approval gates so nothing touches your CRM, finances or data without your sign-off. The deliverable is a production system that runs without constant supervision.
Coaching runs as live 1-on-1 screen-share sessions on Zoom or Google Meet, and recorded for your team to replay later. Each session focuses on your actual codebase, your context engineering gaps, and the specific loop that is failing. Sessions also cover CCA-F exam prep for the Claude Certified Architect Foundations certification.
My Stack Include:
Claude Code CLI · Claude Cowork · Claude API · MCP Server Development · CLAUDE.md · SKILL.md · Anthropic Agent SDK · Context Engineering · Subagent Orchestration · n8n · Make com · GoHighLevel · Supabase · Next.js · LangGraph · GitHub Actions · AI Automation
This works for founders, operators, and teams deep in Claude's ecosystem who need a Claude Code Developer at production depth, not a general AI freelancer who added Claude to their profile last month. Every project ships with retry logic, Slack alerts for error notifications, a Loom walkthrough, and written documentation so your team can run and extend the system independently.
Send me a message describing the manual task your AI should be handling, the workflow that keeps breaking, or the session topic you want covered. I will respond with a specific diagnosis and action plan we can take to achieve a better AI Agent or Idea about Claude.
