Three decades of enterprise software development distilled into strategic consulting. From legacy modernization to cloud-native architecture, Dune Software helps organizations transform their technology with confidence.
Dune Software is led by Saer A. Khan, a Microsoft Certified Professional with 30 years of hands-on software development, technical leadership, and enterprise architecture experience. From early client-server Visual Basic applications to modern cloud-native Node.js services on AWS ECS, Saer has navigated every major technology shift — and helped organizations navigate them too.
Having served as Technical Lead, Senior Architect, and Project Manager at organizations including Infosys, Vanguard, Halliburton, PwC (Entology), and Johnson & Johnson, Saer brings a rare combination of deep technical expertise and pragmatic business acumen. He has led teams, managed multi-million-line codebases, and delivered systems that power call centers, financial platforms, POS systems, and enterprise portals processing thousands of daily users.
Most recently, Saer has been leading the transition of Node.js applications to AWS ECS while supporting Java Spring Batch applications and providing third-tier support for critical institutional platforms — bridging legacy systems with modern cloud infrastructure.
Dune Software was founded to bring this depth of experience directly to companies that need senior-level guidance without the overhead of a large consulting firm.
