What I'm looking for

I’m looking for a team where I can build production-grade, auditable web experiences—pairing React/Vue UX with strong backend architecture (Node/Nest, Laravel) to ship scalable features, not just screens.

I’m a frontend-focused Senior Engineer with 7+ years of experience architecting scalable web applications. I specialize in React (Next.js) and Vue (Nuxt.js), building high-performance, user-centric interfaces for complex domains like insurtech, industrial inspection, and healthcare recruitment.

Unlike pure frontend developers, I bring production-grade backend experience in Node.js (Nest.js) and Laravel, so I can architect full-stack features independently. I turn complex business logic—actuarial tables, pipeline inspection data, and CRM workflows—into intuitive, fast, and auditable user interfaces.

In recent roles, I modernized legacy insurance pricing into an automated rating engine, translating Excel-based actuarial algorithms into optimized TypeScript and reducing quote calculation times by 70%+ with Redis caching. I’ve also built RBAC and compliance-focused logging, led frontend migrations (Shopify to React + Storybook, Vue2 to Vue3), and delivered dashboards and dynamic content experiences that teams can operate without developers.
