About

I’ve been building software for over 15 years: writing code, leading teams and designing products. My focus has always been solving real problems, from architecture to delivery. Now building AI apps with Python, LLMs, RAG pipelines, and multimodal models. I share how I build them and how I use AI coding assistants to build faster. Sharing everything on GitHub under HeyNina101. Follow if you want to build with AI, not just read about it. ◾Content is independent: no sponsorships, no paid placements. All reviews and recommendations reflect my own judgment.
