Hi, my name is
Gustavo Tejeda
DevOps / Cloud / SRE Engineer
Cloud & DevOps Engineer with proven experience automating scalable infrastructure and enhancing security posture in cloud-native environments. Skilled in Docker, AWS, Python, and incident response, with a track record of improving deployment speed, system reliability, and compliance with PCI-DSS and ISO standards.
01.About Me
I'm a Cloud & DevOps Engineer based in Santo Domingo, Dominican Republic, with a strong background in automating scalable infrastructure and enhancing security in cloud-native environments. Currently working as a Junior DevOps Engineer at Change Financial, where I focus on Infrastructure as Code, containerization, and monitoring solutions.
My journey in tech started with technical support roles, which gave me a solid foundation in troubleshooting and system administration. I then transitioned into IT Security Operations at Scotia GBS, where I led vulnerability assessments and automated security processes. This experience shaped my approach to building secure, reliable infrastructure.
I hold an Associate Degree in Cybersecurity from ITLA and completed CCNA preparation. I'm passionate about DevOps culture, Site Reliability Engineering practices, and continuously improving system reliability and performance. When I'm not working on infrastructure, I enjoy contributing to open-source projects and exploring new cloud technologies.
