Webvoltz · Sr. Software EngineerJun 2026 – Present

• CarePath — led architecture and delivery of a multi-tenant SaaS automating clinic-to-patient communication for dental clinics over WhatsApp and SMS, with role-based access control across 4 roles (Super Admin, Clinic Admin, Staff, Patient) — Next.js.

• Built a dynamic workflow engine: master workflows that clinics clone, with steps scheduled relative to patient-specific dates (e.g. surgery date ± N days) and snapshotted at enrollment so template edits never break in-flight patient journeys.

• Integrated the WhatsApp Business API — Meta-approved templates, webhook-driven two-way chat gated by WhatsApp’s 23-hour customer service window, and automatic SMS fallback on delivery failure.

• Implemented red-flag detection on patient replies (keywords in English, Hindi, Gujarati, and Roman script) that raises real-time staff alerts, backed by audit logs with delivery status for traceability.

• Drove a full frontend revamp of the checkout flow, cutting cart-to-order completion time by 40%.

• Architected an event-driven Order Editing workflow on AWS Step Functions with live recalculation, cutting CRM manual workload by 60%.

• Integrated 6 payment gateways (Razorpay, PayU, Snapmint, Pine Labs POS, Gyftr, cash) across online and in-store flows, with Shopify GraphQL APIs as the central OMS for orders, customers, and fulfillment.

• Built a real-time communication platform (chat, Q&A, presence) for 45K concurrent / 240K unique users processing 30M+ messages — Node.js, React.js, Socket.IO, Redis pub/sub for horizontal scaling.

• Developed Narad.io — a notification module built from scratch, delivering system and user events with sub-second latency.

• Guidy — a WCAG accessibility platform: Node.js + Puppeteer API auditing registered sites, with a nightly AWS Lambda cron re-crawling all sites and 3 embeddable widgets delivered via a user-installed script tag.

• Prototyped WebRTC P2P video using native browser APIs; stress-tested dashboards on a chaos platform simulating millions of concurrent WebSocket connections.
