DevOps Engineer, Greenhouse Software 08/2024 – Present NY, USA

•Automated multi-environment deployments using Jenkins and GitHub Actions, reducing deployment errors by 5% and decreasing average release time from six hours to two hours per cycle.

•Containerized 20+ legacy and microservices applications with Docker and orchestrated them on Kubernetes, improving uptime from 92% to 99.5% across multiple production clusters.

•Implemented Terraform and Ansible pipelines on AWS (Lambda, EC2, S3, VPC, IAM, API Gateway), reducing infrastructure provisioning time from three days to three hours.

•Configured Prometheus, Grafana, and CloudWatch dashboards for real-time monitoring, reducing incident response time by 60% and preventing production outages for critical customer-facing services.

•Collaborated with development teams to optimize rollback processes and troubleshoot production issues, improving recovery time objective (RTO) from two hours to thirty minutes during high-severity incidents. DevOps Engineer, IBM 01/2022 – 07/2023 India

•Built automated infrastructure using AWS CloudFormation and Terraform, supporting 15+ high-availability applications with 99.9% uptime and reducing configuration errors by 0%.

•Configured ELK Stack (Elasticsearch, Logstash, Kibana) for centralized logging, accelerating root-cause analysis by 50% and reducing mean time to resolution (MTTR) for critical incidents.

•Conducted API testing and performance benchmarking with Postman and JMeter, identifying bottlenecks and improving average response times from 900ms to 350ms across key endpoints.

•Standardized Git and Bitbucket workflows, reducing merge conflicts by 65% and improving team delivery speed on multiple parallel development streams by 35%. Site Reliability Engineer, IBM 05/2021 – 12/2021 India

•Automated system monitoring using AWS CloudWatch and Python/Bash scripts, reducing on-call alert fatigue by 0% and decreasing incident detection time from 5 minutes to 15 minutes.

•Developed incident response playbooks in Confluence, cutting mean time to acknowledge (MTTA) from 30 minutes to under 10 minutes during production system failures.

•Deployed fixes and patches using Ansible, reducing manual intervention by 80% and improving overall system uptime from 9% to 99% during peak production cycles.

•Analyzed recurring production errors through Kibana logs, resolving six major issues that reduced incident recurrence by 70% over a three-month period.
