Summary

Building AI-powered voice agents on Retell AI that carry live, real-world conversations end to end, from natural dialogue flow to executing function calls and scheduling appointments mid-call. Harden function-call reliability with idempotency locks, timeouts, and structured logging, so the same action never fires twice on a dropped or delayed connection. Own the reliability side of the pipeline: test under real usage conditions and close the gap between a demo that works once and a system a business can depend on.

What I did

Optimized Retell prompts and maintained Cloudflare Workers to improve latency and user experience.
Implemented idempotency locks to ensure consistent vehicle details are provided across multiple agent sessions.
Managed backend logging logic and utilized Cloudflare observability logs.

Results

Achieved call success rates of 80-85% with natural and dynamic agent responses fetching live vehicle inventory.

Co-Mentor

DevWeekendsRemotevolunteer2025 – Present

Mentor a clan inside DevWeekends, a cohort of 2,000+ students from more than 28 countries learning full stack development together. Run weekly code reviews and unblock fellows on real project issues, from broken API integrations to messy state management. Help fellows scope their projects realistically and push them toward shipping working software instead of stalling on planning. Draw on my own fellowship experience to guide newer developers through the jump from tutorials to production-level code.

Projects

Noretmy: Freelance Marketplace

Full Stack Developerpersonal

Built a freelancing marketplace with milestone based contracts and escrow style payments, plus a Cron job that moves sellers up a tier automatically as they complete more work. Added real time messaging and file sharing through Socket.io, so buyers and sellers could stay on the platform for the whole length of a contract instead of moving the conversation elsewhere. Handled Stripe payments with idempotency checks and webhook validation to stop duplicate charges and keep payouts reliable.

MultiMart: Multi-Vendor E-Commerce Platform

Full Stack Developerpersonal

Split the platform into three dashboards, admin, vendor, and customer, each scoped to its own permissions and workflows. Added JWT authentication with refresh tokens and locked down all 40+ API routes with role based access control. Used Redux Toolkit and RTK Query to manage state across the dashboards, cutting down on repeated network calls and keeping the UI in sync.

CampusCore: Learning Management System

Full Stack Developerpersonal

Put together a full LMS covering course enrollment, video lectures, order tracking, and an admin dashboard. Cached course and user data in Redis with a cache aside strategy, which brought average API response times down. Replaced the old polling based notifications with Socket.io, so enrollment and payment confirmations now show up in real time.

MedEaz: Centralized Healthcare Platform

Full Stack Developerpersonal

Built a centralized healthcare platform connecting doctor, clinic admin, and patient portals, each backed by a role-specific AI assistant. Replaced the clinic's paper based OPD queue with a live digital queue and added voice-to-prescription parsing so doctors could dictate scripts instead of typing them. Automated the revenue-split ledger between clinics and doctors and pushed real time notifications through Socket.io, cutting down manual reconciliation work.
