Familiar with PostgreSQL and/or MSSQL, with a focus on secure query design and data encryption. Hands-on experience with Docker, Kubernetes, and cloud platforms (AWS, GCP, or OpenShift), including IAM and security group configurations. Exposure to CI/CD and DevSecOps tools such as Jenkins, SonarQube, Argo CD, JFrog, Snyk, or Twistlock. Knowledge of secure coding standards (OWASP, NIST, ISO 27001) and threat modeling. Strong analytical and problem-solving skills, with a proactive and security-first mindset. Passionate about building resilient, high-performance, and cyber-secure applications that deliver exceptional user experiences. Certification in Secure Software Development (CSSLP, CEH, or similar) is a plus. Experience implementing Zero Trust and API gateway security.
