Project details
🚀 Have a specific AI need that does not fit a packaged solution? Let us build it together.
I build custom AI tools for marketing agencies and SaaS teams that do not want to compromise on a one-size-fits-all template. Whether you need a quick POC to validate an idea, a production-grade integration with your existing stack, or a full agent system, I deliver tailored solutions.
What you get (depending on tier):
• Starter ($1,500): Quick functional POC of one specific AI feature, in 3 days
• Standard ($4,500): Production-grade AI integration with your existing tech stack, tested and documented
• Advanced ($9,500): Full multi-step AI agent or system, production-ready with tests, docs, and team training
Free 30-min scoping call before any purchase — we define exactly what you need and which tier fits.
I am CTO and co-founder of Katoads, an AI SaaS in alpha with 15 marketing agencies. I have built dozens of custom AI tools across SaaS, marketing, gaming, and Web3. Production-grade code, every time.
Powered by Claude Code — fast delivery, no fluff.

💡 Why work with me
I'm CTO and co-founder of Katoads, an AI SaaS currently in alpha with 15 marketing agencies as early adopters. I code every day for this exact persona — I know your workflows, your tools, your constraints. You're talking to a developer who speaks your language, not a freelancer discovering your industry mid-mission.
Beyond Katoads, I've spent 4+ years as a freelance founder/CTO (SaaS, gaming, Web3) — solid track record building production-grade systems from scratch.

• AI Audits for Agencies — 1-day deep-dive to identify your top 5 automation leverage points + chiffred 6-month roadmap

🎯 Best fit for
Marketing agencies (5-50 people), media buying teams, social ads agencies, creative studios, SaaS marketing teams, e-commerce brands wanting to deploy AI in their daily workflows. Not a fit for healthcare, banking/finance, or government work (long sales cycles + stack mismatch).
━━━━━━━━━━━━━━━━━━━━
⚡ Why I deliver fast
I use Claude Code as a coding accelerator — that means I ship working POCs in 3-5 days where most freelancers take 2 weeks. Code is clean, documented, and easy for your team to maintain after handover.
━━━━━━━━━━━━━━━━━━━━
📩 Let's talk
If you have a specific automation in mind, an AI agent to build, or you just want a 1-day audit to identify your highest leverage points — send me a message with your project details. I respond within 24h and can usually schedule a 15-min discovery call within 48h.
