At PATMI, I co-founded an AI-powered storytelling platform and developed its mobile app, backend, and AI systems using Angular, Ionic, Capacitor, NestJS, and Firebase. I designed multi-stage workflows for personalized stories, illustrations, and voiceovers, and built MCP servers and RAG pipelines to support AI assistants and relevant story generation.

At ImID, I built full-stack systems, secure authentication flows, and a Strapi-based CMS that let admins create website pages without developer involvement. Across ARCA, Fast Bank, and freelance projects, I developed frontend and full-stack products, contributed to technical delivery, and provided guidance to developers.
