Expertise
Copywriting
I have spent over 5 years in outbound, leading teams and building revenue functions from the ground up. Before LLM tools became mainstream, I was writing and testing cold outreach manually, refining hooks, positioning, and structure based on real reply data. My copywriting is rooted in buyer psychology, signal-based personalization, and measurable outcomes, not templates.
Go to market strategy
I help B2B companies design and validate their go-to-market strategy from the ground up. I work with top outbound agencies and founders to define ICPs, conduct market research, validate positioning, and build scalable outbound motions. My focus is aligning messaging, segmentation, and channel strategy to revenue goals, ensuring GTM execution is rooted in data, real buyer signals, and clear differentiation.
Revops
I have led transformation projects spanning recurring revenue architecture, customer journey optimization, RevOps design, roadmapping, process redesign, and tech stack strategy.
