With over 12 years of experience, I specialize as an IAM Integration Specialist, architecting enterprise-grade identity and access management solutions. I design secure, standards-compliant authentication and authorization flows using Keycloak, Okta, OAuth 2.0, OpenID Connect (OIDC), and SAML 2.0 — building multi-tenant SSO platforms, enforcing MFA, and implementing role-based and attribute-based access control across complex distributed systems.

As a full-stack engineer, I build scalable backend services with Java and Spring Boot and dynamic frontends with React. I have deep hands-on experience across relational and non-relational databases — PostgreSQL, MSSQL (including column-level Always On encryption), MongoDB, and Elasticsearch — enabling high-performance data access, search, and analytics at scale.

Notable achievements include:

Architected a web-based AS400/IBMi emulator (TN5250), modernizing legacy systems with ReactJS and Spring Boot, bridging mainframe infrastructure with modern web frontends.
Integrated multiple third-party APIs — including Clickatell SMS gateway, Highcharts analytics, and enterprise ERP connectors — streamlining cross-platform data flows.
Implemented MSSQL Always On column-level encryption and OKTA SSO, strengthening enterprise security posture and ensuring compliance.

Beyond full-stack engineering, I'm a passionate solo game developer, currently exploring Unreal Engine and Blender to build immersive 2D/3D game worlds, inspired by my favorite RPGs.
