Hello! đź‘‹

I'm Panneer Selvam Mani Sekaran

I'm a Cloud & Automation Engineering Leader with over 17 years of experience transforming enterprise infrastructure and driving digital innovation. Currently based in Hartford, Connecticut, I lead a team of 17 talented engineers at Accenture, where we architect cloud-native solutions and automation frameworks that deliver measurable business impact.

My journey began in traditional software testing and evolved into a passion for automation and cloud engineering. Over the years, I've had the privilege of working across diverse technology stacks—from mainframe automation to cutting-edge cloud platforms like AWS, Azure, and Oracle Cloud Infrastructure.

What I Do

  • Cloud Architecture: Design and deploy scalable, secure cloud infrastructure using Terraform, managing multi-cloud environments across AWS, Azure, and OCI
  • Automation Engineering: Build enterprise-grade automation frameworks that have saved thousands of hours annually in operational efficiency
  • Team Leadership: Mentor and grow high-performing engineering teams, establish automation strategies, and drive end-to-end delivery execution
  • Innovation: Leverage Generative AI and modern development practices to accelerate code generation and solve complex technical challenges

I recently earned my Master's in Data Science at the University of Arizona, combining my cloud engineering expertise with advanced analytics capabilities. I'm AWS certified (Solutions Architect and Developer Associate) and continuously exploring emerging technologies to stay at the forefront of the industry.

Recent Highlights

  • Built a cloud-native AWS data hub with Redshift Serverless, DynamoDB, Lambda, and full IaC automation
  • Scaled team from 7 to 17 engineers while maintaining delivery excellence across multiple business groups
  • Architected complete multi-cloud infrastructure solutions saving 4,000-5,000 hours annually
  • Led successful migrations and modernizations for enterprise-scale applications

When I'm not architecting cloud solutions or mentoring my team, you'll find me exploring the latest in AI and machine learning, contributing to the tech community, or spending time with family in Connecticut.

I'm always interested in connecting with fellow technologists, discussing cloud architecture, automation strategies, or potential collaboration opportunities. Feel free to reach out!
