Who I am
I build the systems behind high-volume outbound, and teach the AI workflows most people skip.
Day job: I run operations and engineering at Hyperke, an agency that puts automated revenue systems and cold outbound infrastructure behind B2B tech teams. We send 1-2 million cold emails a month. The only reason that volume doesn't fall over is the routing, data cleaning, and enrichment pipeline underneath it.
Most marketing stacks look great in a demo and break the second messy real-world data hits them. My work is the layer underneath: the routing, the dedupe, the enrichment, the retry logic. The unglamorous plumbing that lets outbound hold at a million sends a month instead of dying at ten thousand.
OSS work and education: under @lifeofarjav, I publish working AI workflows, Claude Code setups, open-source repos, and the engineering fundamentals people skip when they hop between tools. Plain language, real repos, no buzzword salad.
What I write about
Five lanes. Real repos, real frameworks, real workflows.
Workflows, prompt engineering, agent systems, and the working vocabulary of AI tools.
Cold email, lead sourcing, pipeline systems, and Go-to-Market that holds at volume.
GitHub repos worth saving, starter folders, watch orders, and free-tier setups.
FastAPI, deep learning papers, MCP, tool calling - the mechanics most people skip.
Psychology, frameworks, operating systems, and the personal side of building in public.
