Projects & Write-ups

{

Greymatter — Monetisation Knowledge Hub

service.yaml manifests + per-PR CI + an hourly aggregator auto-generate a live service catalog and dependency graph across 12 services and 6 consumers, so AI agents can grasp the platform on demand.

Author Payout, revamped

Redesigned the system paying authors ~$300K/month on EventBridge, Metaflows, and DynamoDB for reliability and multi-tenancy, with a companion fraud-detection module.

High-throughput Artifact Platform

A generic, extensible artifact pipeline (currently invoices) producing 50K/day at ~120ms each; state-machine design with per-state retries.

Plans Revamp

A centralized Plan Catalog that cut new-plan onboarding from ~6 service edits to one.

Passbook — user & author ledger

Dynamic backend-configurable time filters with a hot/cold strategy: recent data in MySQL, historical in S3 via AWS Athena.

Career Journey

Pratilipi

Bengaluru

Staff Software Engineer (Founding Engineer) · Monetisation Platform

Joined as Software Engineer (SDE-1) and was promoted to Staff Software Engineer (Founding Engineer) on the Monetisation Platform after ~4 years.

  • •Owns the core payment microservices — Payment, Order, Wallet, Subscription, Coupon. Integrated Razorpay, PhonePe, and UPI AutoPay; the full subscribe-to-collect flow contributes $1.5M+/month.
  • •Re-architected the Payment Service as a producer–consumer pipeline on Go channels, with configurable per-gateway/error retry policies and a maintenance module that drains in-flight work during deploys.
  • •Built a backend-driven checkout that toggles gateways/methods in real time based on downtime and success rates; 100K+ transactions/day.
  • •Built the premium-content access management system — 100M+ calls/day.
  • •Internationalised the wallet for cross-border coin exchange; 100K+ transactions.
  • •Built a multi-tenant Coupon system across 3 verticals from a shared core.
