What I'm looking for

I'm looking to build end-to-end web products where I can work across responsive interfaces, APIs, microservices, real-time systems, and AI-assisted workflows.

I've built Vacuum Tube, a multi-author publishing platform with a custom CMS, AI-assisted human moderation, real-time interactions, and 10 Node.js/Express domain services coordinated through Redis Streams.

I've also built KinoList, an AI-assisted movie discovery and personal library platform with natural-language search, recommendations, secure per-device authentication, event-driven workflows, and a 100/100 Lighthouse score for Accessibility, Best Practices, and SEO.

At Think Again Lab, I developed React and TypeScript SaaS interfaces, delivered a WordPress/WooCommerce NFT store with Stripe payments, designed responsive Figma interfaces, and taught a commercial UI/UX course. I also evaluate agentic AI tasks, model trajectories, multimodal reasoning, prompts, and scoring rubrics through Outlier.
