Experience

1. Aug 2024 – Present

   Senior Software Engineer · Last9

   Remote

   • Led the zero-downtime migration of 50+ live tenants from ClickHouse Cloud to Altinity, significantly cutting compute cost
   • Kept the ingestion pipeline (OpenTelemetry Collector → Kafka → ClickHouse) stable at up to 960M events/min (logs and traces) during IPL and India vs Pakistan traffic peaks
   • Designed and built the APM backend, one of the product's core features, from MVP onwards
   • Built ingestion-time extract, remap and drop rules, plus user-defined physical indexes that route filtered data (say, staging or production logs) into its own table
   • Built cold storage that backs up logs to the customer's own S3 or GCS bucket and rehydrates them on demand, so archived logs are queryable again
   • Automated tenant onboarding, so a SaaS signup or BYOC (bring your own cloud) setup provisions the tenant's infrastructure on Kubernetes
   • Led core Logs and Traces features from design to production
   • Optimized ClickHouse query performance for large-scale logs and traces
   • Built a ClickHouse SQL query generator supporting filters, parsers (regex, JSON, logfmt), and transformations
   • Architected an event-driven S3 ingestion pipeline for logs (near real-time)
   • Built an MCP server for real-time debugging from Cursor, VS Code, and Claude

2. Jul 2022 – Aug 2024

   Backend Engineer · Tazapay

   Remote

   • Lead contributor to Account, Report, KYB, Notification, Event, and OpsDashboard microservices (Go, gRPC, 92% unit test coverage)
   • Cut transaction report generation from 15 minutes to under 1 minute with a new Go service + CDC (Kinesis) architecture
   • Transaction monitoring: 40% faster processing, 15% less memory, 10k–30k transactions/day
   • Designed the PayFac model for the Rapyd provider; refactored card routing in the Router service
   • Built an ops control panel in Go for managing merchant payment methods; reduced ops tickets by 80%
   • Built merchant RBAC and custom notifications for async payment methods (bank/wire transfers)

3. Jun 2021 – Jul 2022

   Software Engineer · Parallel Wireless

   Pune

   • Built microservices in Go with REST APIs; enabled multi-client support in a core service
   • Owned the Alarms/Events microservice; supported CI/CD automation

4. Aug 2019 – Jun 2021

   Software Engineer · Netscout

   Pune

   • Built an automation framework that generates dynamic web reports
   • Built HTTP APIs for standalone C++ tools
   • Restructured makefiles for parallel compilation, speeding up builds

Selected work

• Zero-downtime ClickHouse migration (Last9): 50+ live tenants migrated with zero downtime and significantly lower compute cost.
• APM backend (Last9): Became one of the product's core features; the MVP contributed to product-market fit.
• Ingestion control plane and physical indexes (Last9): Customers trim data before paying to store it, and indexed queries scan only the data they need.
• Cold storage and rehydration (Last9): Long retention at object-storage prices, with archived logs queryable again whenever they're needed.
• Tenant onboarding automation (Last9): New tenants, SaaS or BYOC, come up without manual infra work.
• Event-driven S3 log ingestion (Last9): Logs from S3 become queryable in near real time.
• ClickHouse SQL query generator (Last9): Powers log querying in the product, with query performance tuned for large-scale logs and traces.
• MCP server for production debugging (Last9): Real-time debugging from Cursor, VS Code, and Claude.
• Transaction report pipeline (CDC) (Tazapay): Report generation went from 15 minutes to under 1 minute.
• Ops control panel (Tazapay): 80% fewer ops tickets.
