What I'm looking for

I am looking for a role that fosters innovation, encourages growth, and allows me to work on impactful projects.

I am a highly motivated and results-oriented Software Engineer with a proven track record of designing and developing high-performance web applications. My expertise lies in object-oriented programming, testing, debugging, UI design, and cloud platforms such as GCP and AWS. I am passionate about innovation and growth, always seeking to enhance my skills and contribute to impactful projects.

Currently, I work as a Software Engineer II at Bytecorp.ai, where I lead the containerization of a Python-based web app using Kubernetes, significantly reducing processing time. My experience includes building data pipelines from scratch and collaborating with the CTO to align development with business goals. I take pride in mentoring junior developers and fostering a culture of knowledge sharing within my team.

Previously, I worked at Foretheta and Digitest, where I focused on full-stack development and cloud cost optimization. I engineered software applications that achieved impressive response times and developed systems that identified significant cost savings. My commitment to quality and user experience has consistently driven my work, ensuring that I deliver solutions that meet both technical and user needs.
