See tools ↓What I ship
breakit — 25 AI personas vs your website
One command. 25 AI characters explore your site in real Playwright browsers: a form abuser, a confused grandma, a skeptical buyer, an angry subscriber. Findings are deduplicated, scored, and delivered as an HTML report with screenshots, reproduction steps, and fix suggestions.
npx breakit testComplicer — Compliance monitoring for teams that need proof
SaaS platform for GDPR, accessibility, security, and transparency audits with AI classification, visual review flows, scheduled monitoring, and evidence reports. Built on top of ComplyTest, the open-source Playwright engine that runs 47 real-browser checks and verifies trackers actually stop after consent rejection.
Test Infrastructure at Production Scale
Playwright + TypeScript across 6+ production media websites. Smoke, shadow, PDT, and E2E suites with Grafana dashboards, AI-assisted failure classification, GitLab CI/CD, and Slack alerting. Running in production daily.
KindLM — Testing for AI agents
Behavioral regression testing for AI agents and LLM workflows. YAML-defined tests for tool calls, response quality, compliance. CI-native, multi-model.
@kindlm/cliN8Calls — AI automation that actually runs
Voice agents, chatbots, lead qualification, and workflow automation. 15 live builds with working backends. Fixed pricing from $500. Clients own the system.

All packages → npmjs.com/~kindlmannHow I work
Production-first
Real environments: flaky browsers, changing selectors, CI failures, monitoring, and long-term maintenance.
Tooling-minded
I don't just write tests. I build systems around them: reporting, failure triage, compliance checks, and developer workflows.
Full-stack enough to ship
TypeScript, Python, React, Next.js, Supabase, CI/CD, deployment. I build the tool, the infra, and the interface.
Solo and end-to-end
I scope, build, test, publish, deploy, and monitor.

For clients
I build AI automation systems that need to work in production, not just as demos.
