Founded and built PillCaller, a live voice-call medicine reminder platform for elderly parents—no smartphone or app required.

Integrated IVR voice calling, WhatsApp missed-dose alerts, and ShurjoPay payments, supporting up to 5 family members per account. Deployed hybrid infrastructure—frontend on Vercel, backend on AWS (EC2) with Nginx, PM2 (fork/cluster mode), Let's Encrypt SSL, and full DNS configuration. Wrote unit and integration tests with Vitest, and integrated Google Analytics and Meta (Facebook) Pixel
