Johan Camilo H.

Financial Services & Banking Sector Designed secure, scalable, and highly available cloud architectures tailored to the compliance and performance demands of financial institutions. Implemented cloud infrastructure using Infrastructure as Code (IaC) practices with tools like Terraform and CloudFormation, ensuring consistency, automation, and auditability. Advised clients on cloud architecture best practices, DevOps methodologies, and security standards (e.g., data encryption, network isolation, IAM policies) aligned with regulatory requirements such as PCI DSS and SOX. Conducted FinOps assessments to optimize cloud costs, delivering actionable insights through usage analysis, rightsizing, and scheduled resource automation. Supported pre-sales activities, including solution design, technical proposals, client presentations, and scoping workshops for banking and financial services clients. Led and resolved high-impact incidents involving cloud infrastructure, CI/CD pipelines, and service availability, ensuring minimal disruption to critical banking applications. Provided strategic guidance to clients on cloud transformation, modernization roadmaps, and operational excellence in highly regulated environments. Integrated DevOps practices across client environments, including automated CI/CD pipelines, infrastructure monitoring, and compliance-focused observability. Created detailed technical documentation for architectures, workflows, governance controls, and operational procedures to ensure transparency and knowledge sharing.

As the Technical Lead for a team responsible for cloud implementations, I was focused on orchestrating the migration of our legacy platform to the cloud, overseeing the entire infrastructure implementation process. Leading this initiative, I played a key role in devising and executing strategies for migrating our legacy systems to the cloud environment. A core aspect of our implementation involved setting up and managing EMR clusters, MSK clusters, and leveraging Airflow as our orchestrator to streamline data workflows and processes. All of our infrastructure deployments were managed with Infrastructure as Code (IaC) using Terraform, ensuring consistency, scalability, and reproducibility. In addition to leading the technical aspects of the team, I collaborated closely with stakeholders to ensure alignment with business objectives and requirements. This involved designing and implementing scalable, resilient, and cost-effective cloud solutions tailored to our organization's needs. I also implemented a complete architecture in AWS using MWAA, MSK, EMR, and S3 for big data processing. Achieved a 30% reduction in AWS infrastructure costs by implementing EMR auto-scaling, leveraging managed and spot instances, scheduling downtime for non-production environments, and selecting appropriate EC2 instance types. I have experience with Kubernetes, specifically working with AWS EKS (Elastic Kubernetes Service). My familiarity with EKS included deploying and managing containerized applications using Kubernetes orchestration. I was comfortable setting up clusters, configuring networking, and implementing basic features such as auto-scaling. My knowledge allowed me to effectively work with Kubernetes tools and resources to deploy and manage applications in a cloud environment. I contributed to my team by resolving issues, thereby enabling our business to continue executing our "Journey to Cloud" strategy without interruptions.

I embarked on my journey at Experian approximately four years ago, starting as an Infrastructure Engineer with a focus on middleware platforms including Tomcat, JBoss, Apache, and Nginx servers. Additionally, I handled general Linux administration tasks, primarily with RedHat Enterprise. During this tenure, I spearheaded automation initiatives aimed at maintaining high-availability environments, significantly enhancing the efficiency and reliability of our infrastructure. A notable project I led involved migrating JBoss V6 Standalone to JBoss EAP V7, resulting in improved performance and scalability of our middleware systems. Additionally, I played a pivotal role in the incident resolution team, swiftly addressing critical system issues by conducting in-depth log analysis, identifying root causes, and implementing effective fixes to restore system functionality. After two years of dedicated service, I was promoted and transitioned to Experian Colombia as an Internal Employee, assuming the position of Infrastructure Senior Specialist. In this role, I led a team responsible for supporting a substantial infrastructure technology renewal project, encompassing everything from data location to processing and presentation. This initiative provided exposure to cutting-edge technologies such as Elastic, Kafka, and Cloudera Hadoop, expanding my skill set and contributing to the project's success.

As a Junior Unix and Linux Administrator at Experian DataCredito, I was part of a team responsible for supporting and troubleshooting incidents in the production environment. My responsibilities included: Providing timely support and resolution for platform incidents in the production environment, ensuring minimal downtime and optimal performance. Administering various platforms such as Tomcat, JBoss, Apache, Nginx, and Heroku, ensuring their smooth operation and availability. Implementing system improvements, updates, and security patches to enhance platform performance and mitigate vulnerabilities. Streamlining administrative tasks through automation, reducing manual effort and increasing efficiency. Configuring SSL sockets to ensure secure communication and data protection across platforms. Assisting development teams in conducting proof-of-concept tests on Kubernetes and Docker, providing support and guidance to ensure successful implementation and integration. Through these responsibilities, I developed a strong foundation in Unix and Linux administration, gained hands-on experience in managing diverse platforms, and honed my skills in troubleshooting, automation, and collaboration with cross-functional teams.
