Senior Software Engineer

Red Hat · Performance & Scale · Pune, Maharashtra, IN

  • Maintainer of Krkn, a CNCF open-source chaos engineering framework for Kubernetes and OpenShift — driving roadmap, feature development, release management, architecture decisions, code reviews, and community growth
  • Owned resilience validation for Cross-Cluster Live Migration (CCLM), using chaos engineering to validate VM migration under real-world failure scenarios and establish reliability benchmarks, scalability guidance, and operational best practices for OpenShift Virtualization
  • Led the design and implementation of the Storage I/O Throttling chaos scenario — controlled IOPS and bandwidth degradation across cgroup v1/v2 environments for PVC-backed workloads, powered by a new deploy_io_throttle_pod helper in krkn-lib — with documentation and krkn-hub support shipped in parallel
  • Architected a next-generation pytest-based CI test framework v2 with ephemeral namespace isolation and automated reporting — including the memory-hog and cpu-hog v2 test suites — modernizing legacy validation workflows
  • Introduced event-driven chaos triggers — command-trigger Phase 1 wired through global krknctl inputs — so scenario execution can react to failure conditions the moment they surface
  • Hardened the SLO engine — parallelizing PromQL queries with ThreadPoolExecutor and eliminating duplicate SLO evaluation between per-scenario and final scoring
  • Contribute to the CNCF ecosystem as an LFX Mentor, guiding contributors on automation tooling and docs consistency — and presented Krkn at DevConf Pune 2026

LFX Mentor — Krkn-Chaos

Cloud Native Computing Foundation · CNCF/LFX mentorship · 2026 term 2

  • Mentored an open-source contributor through the CNCF/LFX Mentorship Program on an automated documentation-synchronization bot for the Krkn-Chaos ecosystem
  • Guided the design of a GitHub Actions bot workflow — Python, Hugo/Docsy, GitHub automation, and LLM agents — that detects documentation-impacting changes and generates draft documentation PRs
  • Supported the mentee end-to-end: architecture discussions, problem-solving, open-source contribution practices, code reviews, and iterative improvement toward a practical shipped solution

Senior Lead Software Engineer

HeapTrace Technology · healthcare infrastructure

  • Architected multi-tenant backend services in Spring Boot with role-based access controls
  • Built high-performance ingestion APIs using Falcon framework, handling 10K+ events/min
  • Designed AWS SQS pipeline for real-time, fault-tolerant patient vitals ingestion
  • Saved $40,000 annually by shifting EC2 workloads to Reserved Instances
  • Migrated jobs to Lambda, reducing costs by 75% and improving speed by 5x
  • Implemented Blue-Green deployments for 15+ ECS microservices
  • Architected HIPAA-compliant Engage app with OAuth2/Keycloak auth, Amazon Lexbot, Lambda, and Twilio API
  • Mentored 4+ junior developers; led testing strategy that raised coverage to 85% and reduced bugs by 90%

Profile

whoami.log

Senior Software Engineer at Red Hat on the Performance & Scale team — and maintainer of Krkn, a CNCF open-source chaos engineering framework for testing the resilience of Kubernetes, OpenShift, and OpenShift Virtualization.

My days are spent breaking clusters on purpose — from CCLM migration validation to Storage I/O throttling chaos — then writing the benchmarks and best practices that keep production boring. Before Red Hat, 7+ years at HeapTrace building backend systems with Java, Spring Boot, and Python: multi-tenant services, high-throughput APIs, HIPAA-compliant applications, and cost-saving infrastructure.
