Computer Science with Data Science graduate. Advanced Cybersecurity TSE at Tenable. I am an analytical and detail-oriented Computer Science with Data Science graduate with a strong foundation in ITSM, cloud troubleshooting, and automation. My technical expertise spans Python, MySQL, Kubernetes, ServiceNow, and CI/CD tools, complemented by hands-on experience in incident management, system optimisation, and cross-functional collaboration. During my internships at US Bank Elavon, Viasat, and Toast, I developed and implemented automation solutions, optimised CI/CD pipelines, and enhanced system performance, achieving measurable results such as a 60% improvement in debugging efficiency. I am passionate about excersizing my skills in problem-solving, data analysis, and software engineering to drive operational excellence and improve system reliability. With a solid background in cloud computing, data analysis, and Agile methodologies, I thrive in dynamic environments where I can apply my technical knowledge to troubleshoot applications, streamline processes, and deliver impactful solutions.
Collaborated with the Service Management team to deliver updates on operational resilience and incident management. • Retrieved and analysed ServiceNow reports to identify key operational trends, integrated data into PowerBI dashboards to illustrate issues and enhance decision-making related to improve system reliability for global business lines. • Used SQL to perform joins and retrieve integrated data from multiple tables within the data pond for analysis and reporting. • Proactively investigated and resolved application issues raised by business lines or identified through analysis ensuring minimal operational impact. • Worked closely with the IT 24x7 Operations team to monitor critical payments services and ensured timely detection and escalation of incidents using Excel to analyse and present findings. • Monitored critical payment systems to ensure compliance with DORA and ITIL/ITSM principles, promptly identifying and addressing service disruptions to maintain operational continuity and stability.
• Created an automated sandbox using GitHub Actions for the backend software engineering team to detect changes made and track history of various files made from their private API calls. • Established a retrospective for the team and discussed improvements. • Assisted team with bug fix tickets in back log, corrected them and closed tickets when bug was fixed. • Gained experience working with Github Actions, Kubernetes and ArgoCD to assist backend team with various aspects of their app.
