About Shashank Singh Solanki

I\'m a backend engineer with deep experience in Identity and Access Management (IAM), session architecture, and scalable authorization frameworks. At Postman, I led multiple initiatives that reshaped how millions of users authenticated, collaborated, and securely accessed the platform.I architected the shift from a single-team user model to multi-team membership, unlocking features like partner workspaces and reducing failed team joins by ~200 per day. I also redefined the authentication flow to decouple credential verification from session creation — resulting in modular, idempotent APIs that cut new auth provider integration time from 1 quarter to 2 weeks.My projects often intersect product growth with architectural depth. I led the implementation of enterprise features like SCIM, legal/root domain verification, and network-restricted login flows. One such change enabled a $1.5M enterprise deal and unblocked 1500+ enterprise users, by rerouting auth through team-specific domains. I also introduced Postman\'s first policy engine, unlocking managed identities and team-join governance at scale.I work across backend stacks with Node.js, TypeScript, SQL, Redis, and AWS services (Lambda, API Gateway, DynamoDB, S3), and have deep hands-on experience in JWT, OAuth2, SAML, SCIM, RBAC/ABAC, and multi-tenant systems. I focus on minimizing migration and system churn by designing backwards-compatible APIs and auth flows that abstract complexity for product teams.If you\'re solving large-scale IAM or backend architecture problems, or exploring policy engines and access frameworks for growing SaaS platforms — I’d love to chat. Let\'s connect.
