About me

Allow me to introduce myself—I am Teddy Ambona, a driven and self-taught Python/DevOps Engineer. With over 5 years of focused expertise in SaaS, cloud development, automation, and APIs, I bring a wealth of knowledge to the table.
My proficiency as a Certified Kubernetes Administrator and AWS Solutions Architect enables me to build cutting-edge toolchains from the ground up, ensuring seamless code delivery to production. From orchestrating cloud-based solutions to creating robust automation processes, I am up for any challenge!
Currently, I am actively seeking fully-remote DevOps/Python developer roles within EMEA or APAC time zones. Beyond my technical acumen, I have a keen interest in natural resources investing and stay active with Thai boxing.
If you are seeking a versatile professional to elevate your team’s SaaS initiatives, I would be delighted to connect and explore new opportunities with you. Looking forward to collaborating on exciting projects ahead!
