What I'm looking for

I seek senior frontend roles focusing on architecture, microfrontends, AI-enabled UIs, legacy modernization, and strong developer DX in remote or distributed teams.

I am a Senior Frontend Architect with 10+ years building enterprise-scale applications, specializing in React, TypeScript, Next.js, microfrontends, and AI SDK integrations. I design and implement large distributed frontends, lead legacy modernization efforts, and create generative UIs with streaming responses.

As a founding engineer at ClickUp, I designed the initial modular architecture and shipped the first production release; on Upwork I maintained Top Rated Plus status with 100% job success across 18 contracts and 20,000+ hours. Recently I rebuilt Tesari.ai's UI as the sole frontend engineer and led a monolith-to-microfrontend migration at Universal Weather and Aviation.

I champion practical AI-assisted development workflows, optimize CI/test performance, and deliver robust developer DX through shared component registries, internal CLIs, and domain-driven design. I prioritize maintainability, measurable performance improvements, and scalable team delivery.
