cctabs
Self-aware Claude Code across terminal tabs. The CLI I built so one Claude can spawn and coordinate ten more. Also the engine behind AgentHerder, the practice.
Bio
Fredrik Wollsén is a practitioner at the frontier of human–AI symbiosis. By profession an “Agent Herder,” he orchestrates 12–15 parallel Claude Code sessions every day through cctabs, a CLI he built for the job. Founder of Remember This — an open, local-first capture layer that turns photos, voice memos and daily artifacts into markdown AI can reason over — and of My Transcriber, a free local transcription app. Today he coaches teams at cybersecurity firms (F‑Secure / WithSecure, DNV Cyber) on AI‑native engineering practices, exploring which bottlenecks matter when developer speed no longer does. Previously at Mozilla Research (web measurement). He has been exploring human‑AI symbiosis for a decade.

Coaches engineering teams at F‑Secure / WithSecure and DNV Cyber on AI‑native software engineering — parallel agent workflows, context engineering, and what changes when developer speed stops being the bottleneck.
Products
Remember This
AI for Life. An async, local‑first capture layer — photos, voice memos, receipts, lab results — turned into markdown any AI can reason over. Your life, yours to keep.
My Transcriber
Every voice memo, transcribed. Every time. Free, local, 99+ languages. The boring piece of infrastructure underneath everything else.
AgentHerder
The practice of orchestrating fleets of AI coding agents. Written down. Currently a landing page; a certification track is in the works.
Writing
I write about AI‑native engineering, parallel agent practice, and what happens to software when dev speed stops being the bottleneck — at Positively Fred.
-
The AI‑Native Engineering Playbook — how I actually work with 12–15 Claude Code sessions in parallel.
Past work
-
Web measurement engineer. Co‑author of the WWW 2020 peer‑reviewed paper The Representativeness of Automated Web Crawls as a Surrogate for Human Browsing (WWW ’20, ACM).
-
Independent and startup engineering work across data‑for‑good (Gapminder), adtech (Adoveo / NeamTime), and indie fintech (Clerk). Bridge between the pre‑LLM era and where I am now.
