3rd project: a major pharmaceutical company

• To modernize its IT operations by migrating existing, disparate automation scripts and manual processes to a standardized, Ansible-driven automation framework. This initiative aimed to improve operational efficiency, reduce human error, and enhance the management of their hybrid Windows and Linux server environment.
• As a key member of the automation team, I was responsible for the analysis, design, development, and implementation of Ansible-based solutions to automate a wide range of IT operational tasks.
• I meticulously analyzed existing automation scripts (PowerShell, Bash, and various internal tools) and manual workflows for server management, patching, compliance audits, and software deployments. I identified areas for improvement and designed streamlined, Ansible-based solutions.
• I developed, tested, and deployed Ansible Playbooks and Ansible Workflows using YAML to automate key operational tasks, including: OS patching, compliance audits, Software Deployment, and Observability Integration.
• Leveraged Ansible's API integration capabilities to connect with ServiceNow for change management and incident tracking. This ensured that all automated changes were properly documented and tracked within the company's existing IT service management processes.
• Developed dynamic inventories in Ansible by pulling server information from external databases via API calls. This allowed for accurate and up-to-date inventory management in a constantly evolving environment.
• Worked closely with cross-functional IT teams (server administrators, security engineers, and application developers) to validate workflows, gather requirements, and ensure seamless integration with existing systems. Conducted comprehensive knowledge transfer sessions and created detailed documentation to empower the internal IT team to manage and maintain the Ansible automation framework.
• The successful implementation of this Ansible automation project resulted in significant improvements for the company, like Increased Operational Efficiency, Improved Compliance and security, Enhanced Collaboration, and Reduced Operational Costs.

2nd project: Internal project

• As a member of X-Team's Platform team, I work to provide the best experience for the actual X-Teamers (co-workers) and new/future ones
• That means I contribute by removing blocks or barriers facilitating staff's work or adding new features that could improve the job experience
• For example, some failed SQS messages lead to no action being taken until its expiration
• To solve it, I created a Terraform module to easily document/create CloudFormation metrics, alerts, and thresholds to send those alerts via Slack bot to the desired groups
• This solution fixed the issue and enforced new/replacement cloud resources compliance
• Another example: the developers argued about the difficulties caused by the VPN switching requirement when they jump from the Dev and Prod environments
• To dismiss it, I created a VPC peering connection and concentrated the access from a single VPN instance, controlling the traffic via Iptables and segregating the network groups (ACLs)
• Additionally, I solved an old demand to redirect the non-VPC traffic outside the VPN, improving the navigation speed, saving AWS costs (traffic), and allowing the developer to be connected for extended periods
• I also automate the VPN account management via the Slack bot function
• I've also raised the staff autonomy by extending the bot features, delivering a Self-service credentials reset (AWS and VPN) function, and a bunch of user-account reports, freeing up the engineers to work on value delivery-driven tasks
• With these improvements combined, we could reduce the toiling, whether by ceasing ops-tickets or increasing the delivery quality and speed
• Stack tools: AWS (CodeBuild, CodePipeline, API Gateway, CloudFormation, CloudWatch, SQS/SNS, Lambda, SSM, VPC), Terraform/Terragrunt, Go/Golang (Terratest), Serverless(Javascript), Slack (API/Bots/Modals)
• I have successfully undertaken several impactful projects that significantly enhanced the company's infrastructure and operations
• These experiences showcase my ability to tackle complex challenges and deliver innovative solutions

1st project: Rstudio / Posit.co

• Package Manager Migration: I spearheaded the migration of the company's critical and highly lucrative application, the Package Manager, from EC2 instances to microservices
• This migration involved handling millions of requests per day
• Leveraging my expertise in AWS-managed services such as EKS, S3, RDS, ALB, EFS, and ECR, I orchestrated the migration using Pulumi's GoLang SDK
• Additionally, I integrated the deployment process with GitHub Actions and FluxCD, enabling developers to make changes independently without requiring interactions with the operations team
• This initiative resulted in improved scalability, reliability, and streamlined development processes
• Binary Build Service Migration: In another significant project, I successfully migrated the Binary Build service from Google Cloud (GKE) to AWS (EKS)
• To optimize performance and resource utilization, I implemented a high-elastic cluster utilizing multiple node groups, including Linux, Linux ARM, Win2019, Win2022, Core2019, and Core2022 instances
• Leveraging autoscaling capabilities, the cluster dynamically scaled from 1 to 600 nodes within seconds, efficiently blending on-demand and spot instances
• This migration enabled improved resource allocation, cost optimization, and enhanced overall performance
• Observability and Efficiency: I emphasized the importance of observability using Datadog
• By harnessing the power of observability insights, I facilitated proactive monitoring, efficient troubleshooting, and streamlined maintenance
• This approach resulted in a significant reduction in toil, enabling the team to focus more on developing new features and driving innovation.As a Platform Engineer, I have successfully undertaken several impactful projects that significantly enhanced the company's infrastructure and operations
