What I'm looking for

I'm open to US remote roles where I can lead architecture and delivery for Web3, AI, FinTech, or SaaS products across frontend, backend, cloud, and secure integrations.

I've led full-stack delivery for Fairmint at Endava, building an AI-powered Web3 investment portal across AWS serverless microservices, backend services, customer workflows, smart contracts, and wallet connectivity.

Previously at Coinbase, I built crypto staking features for staking initiation, status tracking, rewards calculation and distribution, KYC onboarding, and secure transaction workflows. I worked closely with product, compliance, and engineering teams to improve reliability and the staking experience.

At Sunroom Rentals, I delivered marketplace features across responsive React.js interfaces, NestJS services, and PostgreSQL data models for rental discovery, listings, and application workflows.

I'm comfortable owning architecture and production delivery across frontend, backend, cloud infrastructure, Web3 integrations, and AI-powered customer experiences for remote engineering teams.
