About

I’m a seasoned DevSecOps engineer with 8+ years in tech (5+ years in DevOps/SRE) who thrives on solving complex challenges in cloud and security. I’ve led projects across AWS and Azure, built scalable CI/CD pipelines and Kubernetes clusters, and automated infrastructure with Terraform, Ansible and CloudFormation. My toolkit includes Bash, Python and Go scripting, monitoring with Grafana/Prometheus, and security scanning (SonarQube, Trivy). I’m passionate about excellence – continually learning the latest tech and best practices to drive results in Agile teams. Beyond technology, I’m fascinated by the science of the mind. I launched Justus’ NeuroPsych Diary, a LinkedIn page and blog where I share insights on psychology, neuroscience, and mental performance. I believe understanding our brains makes us better engineers and leaders. When I’m not architecting cloud solutions, you’ll find me reading neuroscience research or experimenting with productivity techniques. By combining DevSecOps with mental performance strategies, I aim to help tech professionals work smarter and thrive under pressure. In my work and writing, I bring the same curiosity and energy I’ve always had – blending a logical, data-driven approach with empathy and creativity. I love mentoring others, sparking conversations about how psychological insights can improve our daily work, and celebrating wins (whether a seamless deployment or a breakthrough insight about mindset). Let’s connect if you’re interested in cloud infrastructure, cybersecurity or maximizing performance through neuroscience – I’m always excited to exchange ideas with passionate, growth-minded professionals.

Activities and societies: CI/CD, Ansible, Docker, Prometheus, Kubernetes, Lucidchart, AWS Course 1 > Cloud Foundations Learn the fundamentals of cloud computing while being introduced to compute power, security, storage, networking, messaging, and management services in the cloud. Course 2 > Deploy Infrastructure as Code (IAC) In this course, I learnt how to deploy the underlying infrastructure components that provide security and services to our servers by writing scripts using CloudFormation, AWS’ tool for Infrastructure as Code. I used CloudFormation to deploy Infrastructure patterns that are used in the industry broadly and can be readily used to deploy any cloud application. Like in the real world, I began with initial business requirements that you will turn into Cloud Architecture Diagrams. Then I deployed this architecture using CloudFormation. course 3 > Build CI/CD Pipelines, Monitoring & Logging I built a CI/CD pipeline course 4 > Microservices at Scale using Kubernetes I deployed ML microservices and pick the appropriate abstraction for microservices.
