About Tarun Singh

I am an Enterprise Architect and technology consulting leader focused on helping organizations simplify complex systems, modernize platforms, and align technology with business goals.Over the years, I have worked across software architecture, platform engineering, and enterprise architecture, supporting organizations as they scale systems, modernize legacy platforms, and improve the way technology decisions are made.My areas of focus include:• Enterprise Architecture and technology strategy • Legacy system modernization and platform evolution • Architecture governance and decision frameworks • Scalable software and distributed system design • Aligning engineering execution with business outcomes I believe architecture should not exist only in documents or frameworks — it must help teams deliver change faster while keeping systems reliable and sustainable.I currently work with organizations through Kalyaneshwari Consulting Private Limited, where I provide architecture advisory, modernization strategy, and consulting support.I’m currently open to consulting, advisory, freelance, and contract engagements.For details on how I typically engage with organizations, please see the featured section on my profile.
