I help business owners transform their operations with AI - not by pushing technology, but by understanding what's actually slowing you down first.

Most developers build what you ask for. I figure out what you actually need. Through discovery calls and team surveys, I identify the bottlenecks eating up your team's time, then design and build solutions that actually get used - because they fit how your business works.

🔧 What I Build

- AI agents and intelligent automation for business operations
- Custom LLM solutions and ML-powered systems
- Web platforms and SaaS products
- Data systems and pipelines
- Integrations connecting your existing tools

🤖 AI Approach

Not every problem needs AI - and not every AI solution is just "automation." Sometimes the answer is a simple workflow where AI is just one step. Sometimes it's traditional software with no AI at all. And sometimes it's custom intelligent systems: agents that reason and act, ML models trained on your data, LLM integrations that go beyond chatbots. I build the right tool for the actual problem.

🏢 Industries

Distribution, logistics, professional services, real estate, healthcare, e-commerce, marketing, education, manufacturing, financial services.

⚡ Tech Stack

React, Next.js, TanStack Start, Node.js, TypeScript, AWS. AI: Claude, OpenAI, Gemini, custom LLM and ML integrations, etc.

If you're tired of developers who just take orders, let's talk about what's actually frustrating your team.
