What I'm looking for

I’m looking for a full-time remote or hybrid role as an AI Solutions Architect, Solution Architect, or AI Automation Engineer.

At ACD/Labs, I designed integrations between its products and enterprise systems for global pharmaceutical companies, including Pfizer, AstraZeneca, AbbVie, Merck, Novartis and WuXi. I took part in UAT, resolved critical integration issues, and helped take about 10 custom projects to launch in a GxP-regulated environment.

Since June 2025, I’ve designed and implemented AI automation for business processes, including an n8n sales assistant connected to a CRM and company knowledge base. I also built a Telegram city guide and an agent pipeline with Claude Code.

Book Alive is my open-source app: a LangGraph agent turns books into structured character and location cards, while RAG supports chat with citations. I build AI workflows with error handling, retries, logging and scheduled runs, and I’m open to full-time remote or hybrid roles.
