Project details

āœ… I develop AI Chatbots that go beyond basic question-and-answer flows - they can understand context, access business data, automate tasks, and interact with your existing systems. From rapid AI prototyping to production-ready chatbot development, I build solutions around real business needs and user workflows.

āœ… I create OpenAI Chatbots powered by GPT and other leading LLMs, with features like RAG, knowledge bases, API integrations, function calling, conversation memory, and custom AI logic. I can take your chatbot from initial concept and prototype through development, testing, deployment, and ongoing optimization.

Graphic, editorial and presentation design Roman was a fantastic partner throughout this project. His work across graphic, editorial, and presentation design was consistently polished, thoughtful, and on-brand. He took ownership of every deliverable, turned around revisions quickly, and always found smart solutions when requirements shifted. Communication was clear and proactive from start to finish, and the quality never dipped. He caught details I would have missed and elevated the final output beyond what I'd expected. I'd hire Roman again without hesitation and highly recommend him to any client looking for a reliable, talented designer.
