Who I am

I build outbound systems that actually work, and teach the AI stuff most people skip.

Day job: I run operations and engineering at Hyperke. We're an outbound demand generation agency — we help B2B companies get more qualified leads, demos, and sales appointments. Our team sends 5-10 million cold emails a month. The tech stack I built handles all that without falling over.

Most outbound tools look great until you actually use them with real data. Then they break. My work is the stuff underneath — the routing, the data cleaning, the deduping, the enrichment. The boring plumbing that lets you send millions of emails instead of watching everything bounce.

On @lifeofarjav, I share the AI workflows, Claude Code setups, and engineering tricks that actually work. No buzzwords, no theory — just the stuff I use every day.

What I write about

Five lanes. Real repos, real frameworks, real workflows.

All topics
01
AI & Claude

Workflows, prompt engineering, agent systems, and the working vocabulary of AI tools.
02
Outbound & GTM

Cold email, lead sourcing, pipeline systems, and Go-to-Market that holds at volume.
03
Open-source AI

GitHub repos worth saving, starter folders, watch orders, and free-tier setups.
04
Engineering fundamentals

FastAPI, deep learning papers, MCP, tool calling - the mechanics most people skip.
05
Building & personality

Psychology, frameworks, operating systems, and the personal side of building in public.
