About Pavan Akshay Abhange

I build secure, scalable software platforms that make complex systems easier to use, operate, and trust.I’m a Principal Software Engineer with 9+ years of experience building cloud-native applications with C#, ASP.NET Core, JavaScript, and Azure. My strongest niche is modern identity and access management: designing and modernizing authentication platforms, implementing SSO/MFA, integrating enterprise identity providers, and helping teams move from legacy auth patterns to secure OAuth 2.0 / OpenID Connect architectures.In my current role, I lead IAM modernization work across multi-application ecosystems, including migration from legacy IdentityServer implementations to Duende on.NET, federation with Azure AD / Azure AD B2C / ADFS, and rollout of secure token, session, and conditional-access patterns. Beyond identity, I’ve spent my career building full-stack products, APIs, and cloud platforms that are maintainable, scalable, and aligned with real business needs.What sets me apart is the combination of deep back-end engineering, security architecture, and hands-on delivery. I’m comfortable leading ambiguous technical initiatives, partnering across product and engineering teams, and turning complex requirements into reliable software systems.I’m especially interested in Senior and Principal Software Engineer roles focused on platform engineering, application modernization, cloud architecture, identity/security, and high-impact full-stack systems.Open to Senior and Principal Software Engineer opportunities in cloud, platform, and identity/security engineering. If you’re hiring for.NET/Azure modernization, scalable back-end systems, or authentication platform work, feel free to connect or message me.
