What I'm looking for

I seek a dynamic role where I can leverage my expertise in data engineering and cloud technologies, contribute to innovative projects, and grow within a collaborative team environment.

I am a highly self-motivated and results-driven certified technology professional with over 11 years of experience in software engineering, specializing in data engineering, cloud platforms, and machine learning. My career has been marked by a commitment to excellence, where I have successfully developed innovative solutions that align with executive visions and drive operational improvements.

At Tellimer, I developed a platform similar to ChatGPT, leveraging Large Language Models and the OpenAI API to enhance user interaction. My role involved creating real-time applications and optimizing performance, which resulted in a 20% boost in website efficiency. I also spearheaded the migration of legacy systems to modern cloud architectures, significantly reducing operational costs. My experience at KPMG further solidified my skills in full-stack development, where I implemented microservices architectures and established CI/CD pipelines to streamline deployment processes.
