About

Frontend and Software Engineer with experience in regulated fintech environments and AI integration. I've built AI-powered interfaces using CrewAI, CopilotKit, and FastAPI, and led frontend technical direction while collaborating closely to shape the product's overall strategy. I have established design systems and component libraries, automated CI/CD with AWS Amplify, and architected responsive user journeys across B2C and B2B products. I thrive on mobile-first design, component-driven development, and cloud-native workflows with serverless AWS.
