About Ketul Patel

Backend Developer with hands-on experience building secure, scalable, and production-ready backend systems. I specialize in RESTful API development, Clean Architecture, authentication and authorization flows, and data integration across diverse platforms.Currently working at Webosphere Technolab LLP, where I led the migration of a legacy ASP.NET WebForms application to ASP.NET Core 9.0, significantly improving scalability, maintainability, and long-term extensibility. I have architected complete authentication and user lifecycle workflows including new user onboarding, password expiry enforcement, active session validation, account locking for failed login attempts, and secure access management.I have strong experience designing low-code and no-code backend integrations and data connectors supporting multiple protocols and standards such as HTTP/S, REST, GraphQL, SOAP, AMQP, MQTT, OPC UA, and Webhooks, along with AWS S3–based integrations using Amazon Athena queries for analytics and reporting use cases. I have also developed backend services in Python and.NET, focusing on performance, security, and reliability.Passionate about backend engineering, system security, and building robust architectures that power real-world production software.
