I’m a Full Stack Engineer who’s spent the last 2+ years building and scaling production SaaS from 0→1. I take full ownership across distributed backends, payment infrastructure, async systems, and cross-platform product delivery.

In my current role as Founding Software Engineer, I led end-to-end development of two B2B SaaS products serving 8,000+ MAU and driving Rs. 1.5Cr+ monthly transaction volume across 35+ academies. I shipped a cross-platform FlutterFlow mobile app that onboarded 10+ academies in 3 months, integrating payments, notifications, and subscriptions.

I specialize in reliable money movement and operational resilience. I owned multi-provider payment orchestration using Razorpay and Cashfree with webhook-first ingestion, an idempotent ledger, and automated settlement repair—then decomposed a monolithic backend into 4 independently deployable Cloud Run services, reducing deployment downtime by 60%.

I also build high-performance async and AI workflows. I engineered a Pub/Sub invoice pipeline, built a channel-agnostic notification pipeline (WhatsApp/SMS/Email) with routing, deduplication, and audit logging, and automated outreach via Gupshup for 3,500–7,000+ students monthly; I even created “Sahayak,” a real-time voice AI agent using a low-latency VAD→STT→LLM→tool-calling→TTS pipeline.
