Agency-side delivery across several client products — moving between front-end builds and full-stack work, on the MERN side and in Python alongside it.

• Built the marketing site and the dashboard front end for a sleep-health product, including its blog
• Built an outreach platform end to end — Google Workspace and email integration, Apollo and Brevo enrichment, and Twilio SMS (inbound and outbound) plus in-app calling from the React client, authenticated with Google service accounts
• Shipped marketing and landing sites for an overseas client
• Built the front end for an AI-assisted management platform for a European client
• Worked across both ends rather than staying on the client, and wrote Python alongside the core MERN/TypeScript work
