05.2017 - Current
- Designed, built, and maintained production-grade CI/CD pipelines using Jenkins and GitLab CI/CD, integrating automated testing, security validation, and deployment controls to deliver reliable, repeatable, and secure software releases across multiple environments.
- Engineered Infrastructure as Code (IaC) solutions using Terraform and AWS CloudFormation to provision, configure, and manage scalable cloud infrastructure, enforcing consistent deployments, infrastructure standards, and repeatable environment configurations.
- Managed and optimized AWS infrastructure across EC2, S3, VPC, IAM, RDS, and EKS, implementing security best practices, high-availability architectures, network controls, and infrastructure hardening to support reliable production workloads.
- Developed production automation and infrastructure tooling using Python, Bash, and Shell scripting to streamline provisioning, deployment validation, security checks, operational workflows, and remediation activities while reducing manual effort and operational toil.
- Deployed and managed containerized applications on Kubernetes (EKS) using Docker, Helm, Argo CD, and Rancher Fleet, implementing secure deployment practices, workload configuration, autoscaling, rolling updates, and reliable application lifecycle management.
- Implemented cloud security controls across AWS environments, including IAM policies, least-privilege access, secrets management, encryption, and infrastructure hardening to reduce unauthorized access risks and strengthen the security posture of production systems.
- Supported infrastructure security and compliance initiatives by aligning cloud configurations, access controls, deployment processes, and operational procedures with organizational security requirements and audit readiness objectives.
- Investigated and remediated infrastructure vulnerabilities and configuration weaknesses across AWS, Kubernetes, container images, and deployment pipelines, collaborating with engineering teams to prioritize fixes, validate remediation, and reduce production security risks.
- Designed and maintained monitoring, logging, alerting, and observability solutions using Prometheus, Grafana, Splunk, and AWS CloudWatch, enabling proactive detection of infrastructure issues, service degradation, security-relevant events, and operational anomalies.
- Applied Site Reliability Engineering (SRE) practices to improve production availability, resilience, and scalability through SLI/SLO monitoring, service health assessments, incident response, root cause analysis, and corrective action tracking.
- Led production incident troubleshooting, root cause analysis (RCA), and post-incident reviews across AWS, Kubernetes, networking, and application environments, translating technical findings into actionable improvements to prevent recurrence and strengthen operational reliability.
- Collaborated with software engineering, QA, security, and infrastructure teams to address production risks, improve secure development and deployment practices, resolve infrastructure issues, and deliver scalable platform improvements in Agile environments.
