Major Projects
Automated Infrastructure Issue Resolution (MongoDB)
Tech Stack: Golang, RabbitMQ, MongoDB, Jira APIs, Kubernetes, Prometheus, Grafana, Splunk
Impact: 38% manual work reduction replacing 3 years of repetitive processes
Built Golang automation service with node-based execution graph using modular executor pattern. System fetches Jira tickets, compares Atlas cluster goal state vs current state, automatically applies fixes from playbooks or escalates to customers.
Gateway Service Migration (MongoDB)
Tech Stack: Golang, MongoDB Changestreams, Temporal Framework, TTL
Impact: Eliminated race conditions, reduced alert processing time, simplified architecture
Eliminated RabbitMQ dependency by building single gateway service. Used MongoDB Changestreams for event-driven processing and Temporal framework for idempotent child workflows.
Proactive Cloud Outage Detection (MongoDB)
Tech Stack: Temporal, MongoDB, Prometheus, Sliding Window Algorithm
Impact: Proactive detection with confidence scoring, auto-incident creation
Built multi-source correlation engine using sliding window algorithm with 1-hour lookback. Correlates cluster signals with cloud provider health dashboards, produces confidence scores and auto-creates tracking incidents.
ClickHouse Logging Infrastructure (NoBroker)
Tech Stack: ClickHouse, Fluent Bit, Redash, Grafana, LZ4HC
Impact: ₹10L+ annual savings, 10:1 compression, 5,000+ logs/sec throughput
Led Elasticsearch to ClickHouse migration. Researched ClickBench benchmarks, studied Zerodha/Cloudflare deployments, implemented zero-downtime migration. Published article on Medium reaching 1,000+ engineers.
