About
→ 1,500+ hours building GTM systems with Clay, APIs & LLMs
→ 1M+ data enrichments processed through Clay
→ 13M+ leads stored in PostgreSQL for enrichment workflows
That's what my obsession with GTM looks like so far.
I'm a GTM Engineer building end-to-end inbound, outbound, and CRM infrastructure.
Like most beginners, I started on the front lines:
• Posting lead magnets as a content creator
• Writing landing pages as a copywriter
• Making cold calls as a setter
• Running sales calls as a closer
Then one call changed everything.
I went looking for a mentor and walked out with a role building GTM systems full-time.
Fast forward, and now I'm designing the systems that power the front lines.
My stack includes: Clay, SQL, Cursor, Claude Code, Make, Salesforce, BigQuery, Supabase, Python, APIs, LLMs and more.
I'm Clay Certified and building every day.
If you need someone who can design, build, and operate your revenue engine, let's talk.

Testimonial
I highly recommend Vithusan. He took me from a complete beginner to shaping my mindset on how to think like a GTM Engineer. This includes a deep dive into the scientific method and systems thinking.
Our mentoring sessions are ongoing.
