• Experienced in software design, implementation, security, cloud infrastructure as code, CI/CD, and hardware relevant to the role.
• Self-driven with a passion for agile/lean methodologies, delivering customer solutions, owning the SDLC, and practicing DevSecOps principles.
• Enthusiastic about emerging technologies and eager to contribute to team success.
