What I'm looking for

I am looking for a role that fosters innovation, encourages collaboration, and offers opportunities for professional growth.

I am a dedicated DevOps and Python Developer with extensive experience in site reliability engineering and application support. Over the years, I have honed my skills in developing monitoring dashboards, optimizing SQL queries, and automating operational tasks, significantly reducing toil and enhancing efficiency in various projects.

At JPMorgan Chase, I provided critical support for corporate finance applications, managed disaster recovery processes, and coordinated communication with stakeholders. My previous roles at ExxonMobil and Xceligent allowed me to lead teams, implement automation solutions, and oversee complex IT infrastructures, showcasing my ability to adapt and thrive in dynamic environments.

With a strong technical background in programming, scripting, and system administration, I am passionate about leveraging technology to solve complex problems and drive innovation. I am eager to contribute my expertise to a forward-thinking organization that values collaboration and continuous improvement.
