So I handed the choosing to THRØVE, the coach I built - and got the training I actually needed - [I built Craft for myself. Now it's running me.](/writing/i-built-craft.md) - I sat down to save what was working. Four months later it's a harness, and I'm not sure who's running who. - [Giving AI Agents Eyes](/writing/we-have-eyes.md) - I asked three of my agents to fix LinkedIn's feed. Two talked me into something beautiful. The quiet one called it a vitamin and was right ## Projects - [Craft Platform](/projects/craft-platform.md) - A Claude Code plugin that acts as an intelligent harness for your development workflow: your codebase is read-only by default, every change passes through a Write Gate as planned and approved work, and craft tracks your project's history, design tokens, and decisions locally so Claude learns your taste and architectural preferences over time. - [THRØVE](/projects/throve.md) - Not generated. Actually coached. One continuous program that remembers Monday when it writes Friday. - [WodSpark](/projects/wodspark.md) - Built because I had writer's block at the gym - [Knowledge Mining](/projects/knowledge-mining.md) - Turn YouTube content into a searchable knowledge bank with AI search and creator personas - [Interactive Skills Demo](/projects/skills-demo.md) - CSS custom property morph system - entire UI transforms through composed variable sets. - [AI Tools](/projects/ai-tools.md) - Four AI tools - expert routing, digital twin, QA, and UX analysis. MCP servers and agents that handle what shouldn't be done manually. - [AI Consumer Platform](/projects/ai-consumer-platform.md) - Most apps make you learn them. This one learns you. Two colors and three sliders and it's got your design system. Then it keeps watching how you actually work and builds while you sleep ## Contact - Email: darin@darinbuilds.com - LinkedIn: [linkedin.com/in/darin-drobinski-3395ba20](https://linkedin.com/in/darin-drobinski-3395ba20)
