DevOps/DevSecOps, TWFG
January 2018 - Present
- * Designed and Implemented Cloud environments by provisioning VNets (VPC), Subnets, VMs (EC2), Load Balancers, Route53, Firewalls on Azure and AWS. * Designed and implemented infrastructure as code solutions using Terraform and ARM Templates to provision, manage, and automate Azure resources, resulting in 70% reduction in configuration time. * Collaborated with cross-functional teams to develop a cloud migration strategy, evaluating risks and benefits of migrating applications from on-premises to Azure and AWS. * Conducted Dynamic Application Security Testing (DAST) to identify vulnerabilities in running applications. * Implemented Checkmark's for Static Application Security Testing (SAST) tools and processes to analyze code for security flaws. * Utilized Burp Suite for web application security testing, identifying, and addressing vulnerabilities. * Configured Azure Load Balancer to distribute incoming traffic across multiple VM instances to ensure application reliability. * Integrated API gateway configuration changes into CI/CD pipelines to enable automated deployments. * Configured DNS servers in High Availability setup with redundancy and failover mechanisms to minimize downtime and ensure continuous availability of DNS services for critical applications and services. * Integrated Datadog APM to monitor critical applications to ensure timely identification and resolution of performance anomalies and incidents for one of our applications. * Implemented GitHub Advanced Security features such as code scanning, secret scanning to enhance code quality, security, and compliance within software development workflows. * Migrated MSSQL databases from Rackspace to Azure environment efficiently. * Containerized microservices using Docker. * Implemented robust monitoring solutions with tools like Prometheus and Grafana to track applications, system performance, detect anomalies, and proactively address issues, adhering to SRE practices for reliability and uptime. * Been part of architecting highly available and fault tolerant systems with techniques such as Load balancing, clustering, and data replication, leveraging cloud-native services like AWS Elastic Load Balancer (ELB), in accordance with SRE objectives of reliability. * Identify and optimize system configurations, application code, and database queries to improve performance and efficiency. * Integrated Python scripts with CI/CD pipelines to automate the process. * Implemented data encryption mechanisms for sensitive data at rest and in transit using Azure Key Vault, AWS KMS for cloud environments to ensure data confidentiality and integrity. * Managed Kubernetes using Helm, created reproducible builds of the Kubernetes applications. * Developed automated pipelines using Jenkins to orchestrate blue/green deployments. * We have an Incident management process to respond and resolve incidents quickly and efficiently and conduct post-incident reviews (PIRs) to identify root causes and implement preventive measures. Environment: Jenkins, Docker, Kubernetes, Prometheus, Grafana, Datadog, AWS, EKS, EC2, GITHub, Azure Repos, Python, Linux.

January 2016 - December 2018
- * Deployed infrastructure on AWS Cloud Instances and used AWS command line Interface CLI to manage and configure migrated pods from on premises to AWS cloud and designed and implemented lambda functions to aggregate the data from incoming events, then stored result data in Amazon Dynamo DB and used Amazon CloudWatch for simple monitoring of metrics. * Utilized AWS Key Management Service (KMS) for encryption key management, safeguarding sensitive data and ensuring compliance with encryption standards. * Worked with Git repositories within GitLab, including branching strategies, merging workflows and code reviews for a third-party application. * Developed PowerShell scripts to automate various operational tasks, such as server provisioning and configuration management. * Managed RDS database instances, including provisioning, scaling, backup, and monitoring. * Designed, developed, and maintained Ansible playbooks and roles for automating infrastructure provisioning, configuration management, and application deployments across hybrid cloud environments. * Used Checkmark's to scan and identify security vulnerabilities in a variety of software applications. * Implemented and enforced secure configuration management practices, ensuring that systems, databases, and network devices were properly configured with appropriate security controls and patches applied. * Implemented AWS services such as SQS (Simple Queue Service) and SNS (Simple Notification Service) for reliable messaging and event-driven architectures. * Integrated Jenkins with AWS CloudWatch for monitoring pipeline execution, capturing metrics, and generating alarms based on pipeline health and performance. * Integrated Docker builds into CI/CD pipelines using Jenkins to automate Docker image builds and testing. * Implemented Elastic Load Balancers (ELB's) and Auto Scaling groups in AWS of production EC2 Instances to build Fault-Tolerant and highly available applications. * Integrated Jenkins with AWS services such as AWS CodeBuild, CodeDeploy, and CodePipeline to automate the build, test, and deployment workflows. * Deployed and configured Splunk for log management, monitoring, and analysis across distributed environments, enabling real-time visibility into system performance and operational metrics. * Maintained and administered GIT source code tool. Created branches, labels and performed mergers in GIT. Created secured central repositories by using the AWS service Code commit. Integrated with AWS identity an access management. * Monitored canary deployments using CloudWatch alarms and metrics to detect performance issues. * Implemented strategies for gradual migration and decommissioning of legacy systems from Rackspace. Environment: AWS, GIT, Jenkins, SonarQube, Docker, MySQL, YAML, Python, Linux, Ansible, Terraform, New Relic, Splunk, JIRA.
