What I'm looking for

I'm looking to build AI-powered and customer-facing products end-to-end, combining frontend architecture, UX, API integration, and product ownership.

I've built AI-powered SaaS products at Salespeak.ai, owning features from problem discovery and UX through implementation, testing, and production.

I lead frontend architecture for React and TypeScript applications, including embeddable conversational AI widgets, launchers, and an Admin platform for configuring customer experiences. I integrate REST and GraphQL APIs with Axios and React Query, and iterate on prompting and product logic to improve LLM-powered interactions.

Previously at Amberflo.io, I helped establish the frontend foundation for metering, usage-based billing, and customer billing products, later leading architecture, code quality, and engineering practices. My work also includes fintech web and mobile applications at Lemon Cash, alongside product design, UX, and end-to-end delivery.
