Most businesses don’t need more AI. They need fewer manual steps, faster processes, and systems that quietly run in the background. That’s what I focus on. If you’re dealing with repetitive tasks, messy data, or workflows that feel harder than they should be, I can help simplify and automate them. ✨ What I can help you build: • AI-powered business analysis agents These systems go beyond dashboards. They analyze your business data, spot trends, and highlight what actually matters. Instead of digging through reports, you get clear insights and suggested actions you can use right away. • AI-powered dashboards Not just charts and numbers. I build dashboards that explain what’s happening in your business in plain language. It feels more like having an analyst inside your system than just a visualization tool. • RAG-based service chatbots Chatbots trained on your own data such as documents, PDFs, and internal knowledge. They give accurate, context-aware answers so your team or customers don’t have to search manually or rely on guesswork. • AI researcher agents and voice agents Need something that can gather information, summarize it, and help you think faster? I build agents that can research topics, monitor data, and interact through voice using Vapi for more natural experiences. • Object detection AI systems Computer vision systems that can detect and track objects in images or video. Useful for real-world cases like monitoring, analysis, or automation where visual data matters. 🌐 Why working with me feels different I don’t just build what’s asked. I try to understand what you actually need. Sometimes the best solution isn’t more complex, it’s just smarter and simpler. I’ll always tell you honestly what makes sense and what doesn’t. I care about whether the system is actually useful in your day-to-day work. Not just “it works”, but “you’ll rely on it”. • I think about the bigger picture, not just the task • I keep communication clear and straightforward • I stay transparent throughout the process No overengineering. No unnecessary complexity. Just systems that work. 🌟 Let’s Build Something Useful If you’re working on something and thinking “this could be automated”, you’re probably right. Send me a message. Even if your idea is still rough, we can figure it out together. less -
