DJAI

Control Spotify from your agent with natural language.

Playing now

Queue, search, play and automate music workflows.

Building practical AI products.

I build AI agents, developer tools, and automations that integrate with real APIs and solve real workflows.

Agents

Tools connected to real products, APIs and user workflows.

Automation

API integrations and backend workflows that remove repetitive operational work.

Full-stack

Next.js, React, Node.js, Python and databases for complete product delivery.

Shipping

I care about packaging, docs, setup flows and product demos, not only code.

Skills for shipped AI products.

I combine AI agents, backend integrations, automation platforms and product engineering.
