PuppeteerNest.jsTo be not just a wrapper.
Fullstack developer specializing in interfaces for AI systems that people can actually use without wanting to throw their laptop.
I work in the gap between complex AI pipelines and functional products. Chat interfaces that maintain context, automation tools users don't immediately distrust, attempting to build systems that adapt to human behavior instead of the other way around by fighting the developer urge to put buttons everywhere.
Five years freelance. Clients range from startups figuring things out to scale ups with budgets and bureaucracy. Work includes chat pipelines, vector search systems, canvas, generative UI, fraud detection dashboards and authentication flows that balance security with not annoying everyone.
UX strategy for AI products. Based on data understanding why users stay or leave, then building accordingly to what brings the most on the table. Yet still a maniac on typesafety and quality process like e2e and linters, more than ever since we brought yes-man AI agents in our dev flows.
