What I'm looking for

I’m looking for a backend role where I can own production APIs end-to-end, move quickly in a startup environment, and build integrations or AI-powered features that directly improve onboarding, performance, and user outcomes.

I’m a backend-focused developer with 10+ months of internship experience building production APIs, CRM integration pipelines, and AI-powered tools at product companies. I’ve shipped “FirstDraft,” a live Gemini-powered app, and built HubSpot–Salesforce migration tooling that automated cross-platform workflows end-to-end.

I’m comfortable owning backend systems end-to-end—engineering reliable REST API integrations, JWT-based auth, and query optimizations that handle high-volume transfers without degradation. I move fast in startup environments, design architecture to reduce processing overhead and scale concurrent migrations, and build with a product-minded, user-impact mindset.
