Technical depth.
Customer obsession.

I've spent the last two years at the intersection of engineering and sales, building demos, running discovery calls, handling technical objections, and closing pilots. Sales Engineering is the natural fit.

At Ethlos, I owned the full pre-sales cycle from initial demo to pilot adoption across $1B+ project portfolios. I've debugged live in front of customers, translated complex cloud architecture into business outcomes, and built the kind of trust that turns pilots into contracts.

Now I'm looking to bring that same energy to a high-growth SaaS company where I can help customers get the most out of a product I believe in.
