Kobe is an AI superconnector. It finds the warmest path to a person through your own network (LinkedIn, email, Slack, Notion) and drafts the intro request, sending nothing without your OK.

• Three full-time weeks in October 2026: 509 of 918 commits in the v3 repository (Hono, Cloudflare Workers, Postgres), 157 of 750 in the Electron desktop app, plus the pitch deck and kobe-eve.
• Co-developed a six-stage agent pipeline in Python (Claude Agent SDK, about 20k lines) with full agent tracing and a debug dashboard.
• Wrote a 15k-line architecture handbook across 72 repositories in two days; it surfaced a probable live bug in the LinkedIn session handling.

Julia is an AI phone receptionist for hair salons. It answers calls around the clock and books, moves or cancels appointments directly in the salon's booking system. Used by 100+ salons as of November 2026.

• Built a 13-method Belbo booking driver and merged it with a colleague’s parallel integration; added the onboarding wizard, dashboard, a limitations doc and scripts against the vendor test account.
• Rebuilt the simulation dashboard (a colleague had built the predecessor) in which GPT-4o-mini plays the caller against the voice agent and a judge model rates every call; restructured the test suite from 67 to 267 atomic cases.
• Verified the “regulars only” booking gate against an independent Python re-implementation before shipping: 400 generated catalogs covering every key shape in the fleet, 3,200 comparisons, zero deviations.

Startup tours take 15 to 22 students for three or four days into a European tech hub for eight to ten visits at startups, VCs and corporates. I research the ecosystem, do the outreach, select participants and host on site.

• Organized the tours to Munich (May 2026: NVIDIA, BMW, Celonis and others) and Amsterdam (June 2026: DuckDB, Flow Traders, Antler); Zurich follows in November 2026.
• After zero replies to five cold outreach packages, switched to warm channels (alumni, the sdw network, b2venture) with a six-step quality check for every message.
• Wrote the first tour playbook (milestones, selection scheme, retro template) as onboarding for the next team member.
