Open to work

I enjoy building real features that solve real problems, from the first schema to the production deploy, and making sure they hold up once people start using them.

Experience

KonceptsFounding Engineer Feb 2026 — PresentBengaluru

Architected and solely built the FastAPI backend for an AI learning platform for IB schools (PYP, MYP, DP), serving 12K+ DAU on AWS ECS.
Real-time Voice + Avatar AI tutors on LiveKit: streaming ElevenLabs STT/TTS, VAD, semantic turn detection. A live whiteboard, math widgets and 3D models stay synced to word-level speech timing.
A Generative UI content pipeline where the LLM composes and live-edits a registry of 46 interactive components through validated JSON props and patches. Running it on Batch APIs halves generation cost.
Exposed internal tools as MCP servers, so content, ops and admin workflows run through AI agents.
Stripe billing with exactly-once checkout (idempotency keys, Postgres advisory locks, frozen price quotes), an order-independent webhook inbox, and drift-detection jobs.

PrepAiroFounding Engineer May 2025 — PresentBengaluru

Payments & subscriptions across Razorpay, Google Play Billing and Apple IAP: signature verification, webhook retry safety, event dedupe, an order state machine, refunds and reconciliation.
Airo, a type-safe UPSC AI tutor on Pydantic-AI with SSE streaming, intent routing and OCR grading of handwritten answers. It sits behind an LLM circuit breaker with cross-provider failover and cost-aware model routing by user tier.
A Current Affairs pipeline on AWS Bedrock that turns daily news into RAG-grounded MCQs in English and Hindi, plus a daily two-host AI podcast made with ElevenLabs multi-speaker dialogue.
A Kafka-backed notifications service with batching, dedupe, rate limiting and failure recovery. Paid video is delivered through S3 + CDN with signed access.
CI/CD with GitHub Actions, ECR, EKS and Argo CD, from build to production rollout.
