I build applications from scratch: backend architecture, REST API, React/Next.js frontend, Stripe integrations, authentication systems, databases, cloud deployment, and workflow automation.

Recently, I developed Gogokodo, an e-learning platform that reached 277 learners and 7,000 monthly visitors. I also integrate LLMs into products: OpenAI, Anthropic Claude, RAG, agents, business assistants, and AI-assisted internal tools.
