Harshit Jain

System Reliability: Managed the reliability, availability, and performance of critical production systems, focusing on stability and customer experience.

Production Ownership: Took end-to-end ownership of production services, proactively identifying reliability risks and implementing preventive measures to minimize customer impact.

DevOps Architecture: Collaborated with cross-functional teams to design and document end-to-end DevOps architecture, defining Git/source control, CI/CD, AWS EC2 or Kubernetes deployment, networking, security, monitoring, and logging.

Cloud Reliability: Designed, operated, and improved highly available AWS infrastructure with a focus on reliability, scalability, and resilience.

Infrastructure as Code: Provisioned and managed infrastructure using Terraform and Ansible, enabling consistent and repeatable environments.

CI/CD: Built and improved CI/CD pipelines to automate application delivery, reduce deployment risks, and enable reliable software releases.

Cost Optimization: Monitored and optimized cloud costs through right-sizing, autoscaling, and resource cleanup while maintaining reliability and performance.

Reliability Engineering: Identified single points of failure, service dependencies, bottlenecks, and operational risks, implementing solutions to improve system resilience.

Security: Implemented infrastructure and application security best practices, including IAM, least-privilege access, encryption, vulnerability remediation, and secure configurations.

Incident Management: Led incident response, troubleshooting, service restoration, and post-mortem analysis for critical production incidents.

Monitoring & Observability: Developed and maintained monitoring dashboards, metrics, logs, traces, and alerts to provide visibility into system health and performance.

Alert Management: Improved alert quality by tuning thresholds, reducing noisy alerts, and ensuring alerts were actionable and aligned with service health.

Service Level Objectives: Defined, measured, and reported SLIs, SLOs, SLAs, and error budgets to drive reliability improvements and prioritize engineering efforts.

Toil Reduction: Identified repetitive operational tasks and eliminated them through automation, self-service tooling, and improved engineering processes.

MTTD/MTTR: Improved Mean Time to Detect (MTTD) and Mean Time to Resolve (MTTR) through enhanced monitoring, automation, runbooks, and incident-response processes.

24/7 On-Call: Owned front-line 24/7 on-call rotations and incident response for critical production systems, serving as the first line of defense for production incidents.

Root Cause Analysis: Performed detailed root-cause analysis and implemented permanent corrective actions to prevent recurring production issues.

Documentation: Created and maintained runbooks, architecture documentation, troubleshooting guides, operational procedures, and incident-response documentation.

Cloud Hosting: Managed and supported cloud-hosted environments, ensuring reliable infrastructure, efficient resource utilization, scalability, and high availability.

Server Management: Managed and maintained production Linux servers, including provisioning, configuration, patching, troubleshooting, and performance optimization.

Virtualization: Managed virtual machines including resource allocation, provisioning, migration and performance optimization.

Linux Administration: Performed Linux system administration, including package management, filesystem management, networking, user administration, service management, and system troubleshooting.

Network Troubleshooting: Troubleshot DNS, TCP/IP, routing, firewall, load balancer, connectivity, and network performance issues affecting production services.

Performance Optimization: Analyzed and optimized server performance by troubleshooting CPU, memory, disk I/O, network utilization, processes, and application behaviour.

Production Operations: Provided end-to-end operational support for production infrastructure, from server provisioning and deployment through monitoring, troubleshooting, optimization, and decommissioning.

Log Management: Analyzed system, application, web-server, and security logs to troubleshoot incidents, identify performance issues, and detect abnormal behaviour.

Customer-Facing Support: Provided technical support for critical hosting and infrastructure issues, effectively communicating with customers and internal engineering teams during incidents.

Safe Deployments: Implemented safe deployment and automated rollback strategies to minimize production impact during application and infrastructure changes.

Mentorship: Mentored junior engineers and promoted SRE principles, operational excellence, automation, observability, and reliability best practices across engineering teams.
