About this gig

Have an AI idea, or a manual process that AI could take over? I'll design, build and deploy a custom AI application for you, from first prototype to production-ready app.


I'm Piyush, a marketing automation lead and full-stack AI developer. I designed and built an internal AI platform end to end (Next.js, React, TypeScript, Claude API) that is used across 8 brands and automates about 80% of a marketing team's manual work.


What I can build for you:

  • AI assistants and copilots that work with your own documents and data
  • AI SaaS products and internal tools with login and user roles
  • AI that takes actions in your tools (CRM, Jira, Slack, Google)
  • Document, PDF, image and spreadsheet processing with AI
  • Automated reports, dashboards and alerts


Tech: Claude (Anthropic) and OpenAI APIs with tool use, Next.js, React, TypeScript, Node.js, Python, Prisma, MySQL/Postgres, Docker, REST APIs, JWT auth.


Clean code, secure setup and full source code. Message me with your idea and I'll suggest the fastest way to build it.
