Expert-Vetted & Top Rated Plus on Upwork | 100% Job Success Score | 100+ Projects Delivered

I build AI voice agents, AI chatbots, and workflow automation systems that
handle real business operations — lead qualification, appointment booking,
CRM automation, and customer support, running in production, not demos.

I hold Upwork's Expert-Vetted badge, awarded to roughly the top 1% of
freelancers after direct review by Upwork's talent team — combined with Top
Rated Plus status and a 100% Job Success Score across 100+ completed
projects. Between the two badges, this is Upwork's own screening confirming
consistent, high-caliber delivery, not just self-reported experience.
