Sivalingam Ramasamy — CEO

I design scalable platforms that eliminate hidden bottlenecks and unlock engineering velocity. With 13+ years of experience building and modernizing distributed systems, I operate at the intersection of architecture, performance engineering, and AI-augmented development. My focus is simple: Build systems that scale - without accumulating technical debt. Recent architectural impact includes: Reduced billion-record data migration from 12 hours to 5 hours Designed AWS-based systems handling 1200+ requests per second Diagnosed and eliminated shared SQL infrastructure bottlenecks affecting production stability Reduced recurring production alerts to zero post-release Built AI-driven automation that reduced multi-repository OEM onboarding from months to minutes Introduced AI-assisted code and SQL review prompts to systematically improve engineering quality I approach architecture as a systems problem - aligning application design, data flow, infrastructure, and observability into cohesive, high-performance platforms. Beyond hands-on architecture, I drive engineering enablement - leading AI adoption initiatives that enhance developer productivity while maintaining strong engineering fundamentals. My work directly impacts reliability, operational efficiency, and product scalability. Interested in global-scale SaaS platforms, distributed systems strategy, and AI-driven engineering transformation. Open to senior technical leadership, platform architecture, and high-impact product discussions.
