At Techtiz, I delivered 10+ production AI platforms across logistics, healthtech, HRtech, legaltech, and creative tooling. I shipped RAG pipelines and multi-agent Claude orchestration for products including warehouse management, HR automation, contract review, and knowledge assistance.

For BrandSync AI, I built a multi-tenant content platform with brand-grounded AI generation and an approval workflow. I also built a wine warehouse management backend with a 13-state order lifecycle, and a health platform with AI-generated fitness plans and bloodwork insights.
