Hi! My name is Deshan Lanka.
Thank you for stopping by my GitHub Profile! 😊
I am a passionate technology professional focused on Identity & Access Management (IAM), Cybersecurity, Backend Development, Cloud Technologies, and Artificial Intelligence. I enjoy designing secure authentication solutions, building scalable applications, integrating enterprise systems, and solving complex technical problems.
-
🔭 Currently working on:
- Designing and implementing enterprise Identity & Access Management (IAM) solutions.
- Working with IBM Security Verify Access (ISVA) for authentication, federation, and access management.
- Implementing secure authentication and authorization using OAuth 2.0, OpenID Connect (OIDC), SAML 2.0, MFA, and PKCE.
- Developing and integrating secure REST APIs and backend services using Java and Spring Boot.
- Working with WebSEAL, LDAP/ISDS, Active Directory, DB2, HADR, and enterprise SSO architectures.
- Exploring Machine Learning and AI for intelligent forecasting and practical real-world applications.
-
🌱 Currently learning & exploring:
- Advanced Identity Security and IAM architectures.
- Modern OAuth 2.0 / OIDC security patterns and API security.
- Cloud-native architectures, Docker, Kubernetes, and DevOps.
- Advanced Machine Learning, Deep Learning, and Explainable AI (XAI).
- Building intelligent applications using LLMs, RAG, LangChain, and vector databases.
- Modern iOS and mobile application development.
