Experience
Clinixs
Backend & AI Engineering Intern (Healthcare SaaS Startup)
Own end-to-end development of backend features and AI systems within an existing production codebase, including a patient-facing AI agent that routes WhatsApp Business Cloud API queries through an LLM for automated response generation.
Designed a Supabase data layer for patient and clinic records with a PII-stripping stage upstream of every LLM API call, meeting India's Digital Personal Data Protection (DPDP) Act compliance requirements.
Set up GitHub Actions CI/CD — automated lint and type-check gating on every pull request, with Vercel auto-deploy on merge — for Next.js backend services built for reliability under production data-compliance constraints.
