Who I
am.
Frontend-focused engineer with hands-on experience building and scaling crypto/Web3 and fintech products. Skilled in modern web technologies, smart contract interaction, and shipping customer-facing applications.
I build products end-to-end when needed — from UI systems and design tokens all the way to API design. Strong contributor in fast-paced environments, collaborating across teams to deliver functional, scalable, and secure solutions.
What differentiates me is execution: I ship functional systems, not just interfaces — combining frontend depth with working knowledge of backend, real-time infrastructure, and blockchain interactions.
