Senior Infrastructure Engineer
I am a seasoned software and infrastructure engineer with a wealth of expertise spanning backend development, DevOps, cloud technologies, and scalable system design. Over the years, I have honed my skills through diverse experiences, building robust, high-performing solutions for startups and global enterprises alike. In backend development, I have worked extensively with modern frameworks and languages such as Ruby on Rails, Node.js, Golang, and Python, crafting scalable APIs, optimizing performance, and leading architectural transitions. My data storage expertise includes proficiency in MySQL, Redis, and Elasticsearch, where I have designed solutions to handle billions of rows and millions of documents while ensuring high availability and responsiveness. On the DevOps front, I bring deep knowledge of cloud ecosystems like AWS and GCP, combined with hands-on experience in container orchestration using Kubernetes, Docker, and OpenShift. I have designed infrastructure as code using Terraform, CDKTF, and Ansible, and implemented observability systems with tools like ELK, Prometheus, and Datadog. My expertise extends to CI/CD pipelines, where I’ve utilized Spinnaker, GitLab, and GitHub Actions to automate and streamline complex workflows. Driven by a problem-solving mindset and a passion for scalable, efficient systems, I thrive in environments that demand adaptability, precision, and continuous improvement. Whether optimizing databases, automating processes, or architecting cloud-native solutions, I am committed to delivering results that align with business objectives and exceed expectations.
