# About Vishal Kumar

Vishal Kumar, also known online as vishalx360, is a senior software engineer based in Bengaluru, India. He works across product engineering, backend systems, and platform reliability. His strongest work is at the boundary between product complexity and production scale: turning ambiguous operational problems into systems that teams can understand, operate, and trust.

At Atlan, Vishal built Blackbird, a declarative configuration-management system in Go with Temporal-powered drift detection and idempotent remediation across 800–1,000 customer tenant clusters. It became the configuration source of truth for 20–30 services and eliminated configuration-drift P0 incidents. He also migrated more than 600 production tenants to CloudNativePG with zero data loss and zero downtime and helped productionize Temporal for durable workflows.

Previously, at OpeninApp, he built an AWS analytics pipeline using Kinesis Firehose, S3 Parquet, Glue, and Athena for a redirection system handling 1–5 million daily hits. At Relecture, he was the first and sole engineer for two years, built the product and deployment stack from scratch, reduced infrastructure cost by 80%, and helped grow the engineering team from one to three.

Vishal is most useful on work that demands end-to-end ownership, sound technical judgment, and reliable delivery. His public work, employment history, selected projects, and contact details are documented on this canonical domain.
