I am a results-driven Senior System Architect and Systems Engineer with a robust background in designing, developing, and managing cloud infrastructure and big data technologies. With over a decade of experience in the tech industry, I have honed my Python, Bash, and Java skills, complemented by deep expertise in Unix/Linux system engineering, networking principles, and cloud services.Currently, I am leading the infrastructure design and development for Oracle Cloud Infrastructure (OCI) at Oracle, focusing on Kerberos and Storm services. My role involves managing and optimizing Cloudera Hadoop clusters, transitioning standalone Kafka platforms into OCI's Big Data Service, and ensuring the seamless migration of AWS clusters to OCI.Throughout my career at Oracle (formerly Cerner Corporation), I have successfully led cross-functional teams to deliver complex projects, optimize system performance, and implement innovative solutions to enhance scalability and efficiency. My key achievements include:Infrastructure Leadership: Designed and developed OCI Cloud infrastructure for Kerberos and Storm services, creating 9 BDS clusters per environment.Cluster Management: Oversaw 30 Cloudera Hadoop clusters in production, with the largest Kafka cluster comprising approximately 100 nodes and Storm clusters averaging 20-30 supervisors.OCI Migration: Spearheaded the transition to OCI, planning for 6 Storm clusters per environment and additional clusters for production.High-Volume Data Processing: Managed Storm topologies moving up to 52 million messages every 10 minutes and optimized Hadoop clusters ranging from 100 to 1,000 nodes.Technical Optimization: Implemented configuration as code to enhance scalability and efficiency and adopted new tools and technologies during code uplifts.I am passionate about leveraging my expertise in system architecture, cloud infrastructure, and big data technologies to drive innovation and operational excellence. My technical acumen is matched by solid project management skills, enabling me to lead projects from concept to completion while ensuring stakeholder satisfaction.Open to new opportunities: I am actively seeking challenging roles as a Senior System Engineer, System Architect, Lead System Engineer, or Site Reliability Engineer.
