About Me

Building the infrastructure that makes outbound work.

I'm an Apollo.io Certified Specialist focused on the technical side of outbound sales — the infrastructure, systems, and configurations that determine whether your campaigns reach the inbox or the spam folder.

Why technical infrastructure matters.

Most outbound programs fail quietly. The emails go out, but they land in spam. The sequences run, but the contacts never see them. The CRM fills up, but the pipeline stays empty. In almost every case, the root cause is infrastructure — not strategy, not copy, not targeting.

I became obsessed with the technical layer because that's where the leverage is. Getting SPF, DKIM, and DMARC right. Warming inboxes properly. Structuring sending domains to protect your primary domain. Building Apollo.io correctly from day one so it actually integrates with your CRM instead of creating data chaos.

That's the work I do. Not just setting things up — setting them up to last and scale.
