I help startups, scale-ups, and enterprises implement secure, scalable, and user-friendly authentication systems using Keycloak and other modern identity providers.
With 6+ years of specialized experience in Identity and Access Management (IAM), I design and deliver production-ready Single Sign-On (SSO) solutions, passwordless authentication, and fine-grained authorization that reduce security risks while improving user experience.
My core expertise includes:
Keycloak implementation, optimization, clustering, custom extensions (SPI), realm design, and high-availability setups (Docker + Kubernetes)
Complex SSO/Federation using OIDC, SAML 2.0, OAuth2
Integration with Microsoft Entra ID, Okta, Auth0, AWS Cognito, Google Workspace, Salesforce, Oracle IAM, and others

User provisioning & lifecycle management with SCIM 2.0, LDAP/AD sync, and bulk migrations
Troubleshooting and fixing common identity issues (redirect loops, token errors, SAML assertion problems, session management)
I work fluently with Spring Boot, .NET, Node.js/NestJS, React/Next.js, Golang, and strong DevOps practices (AWS, Oracle Cloud, Terraform, CI/CD).
Whether you need a fresh Keycloak setup, migration from Auth0/Okta/Cognito, custom authenticator development, or long-term IAM strategy — I deliver clean, well-documented solutions quickly (often within days for standard implementations).

With over 16 years of expertise in Delphi technology, I've cultivated a comprehensive skill set encompassing Design Specification Development, Functional Specification, Project Implementation, Application Enhancement Delivery, and intricate knowledge in Multi-tier Applications Presentation, Application Server Layer, and Data Setup Architecture.
Throughout my career, I've adeptly navigated through various Delphi versions, including 6, 7, 2010, Rad Studio XE5, XE8, and XE10.2. This versatility allows me to tailor my approach to meet diverse project requirements efficiently and effectively.
My core technical proficiencies lie in Delphi, complemented by the FMX Framework, FireDAC Framework, MS SQL Server, and Oracle. I'm also versed in Distributed Computing technologies, including DMVCFramework, TMS Sparkle, Data Snap REST, EMS, Web Services, and SOAP. Beyond these, I have ancillary skills in JavaScript, C#, and .NET.
My experience extends to a variety of Delphi components, including DevExpress, TMS, ipControls, FastReport, Quick Report, Eurekalog, DBISAM, UniDAC, SDAC, and FirePower. In web development, I'm knowledgeable in Web Frameworks like UniGUI and Intraweb.
I excel in FireMonkey, demonstrating significant experience in developing cross-platform applications for iOS, Android, OS X, and Windows. My proficiency encompasses web technologies such as REST, SOAP, DataSnap, XML, JSON, and protocols like HTTP and SMTP.
I have engaged with multiple databases, including Paradox, NexusDB, DBISAM, MSSQL, and Oracle, ensuring I deliver tailored and efficient solutions. My experience in upgrading projects from non-unicode and older Delphi versions (6, 7, 2006) to the latest XE versions has enabled seamless transitions for clients.
Moreover, I successfully migrated a Point of Sale system from VCL to FMX, showcasing my adaptability to evolving technologies and commitment to meeting client needs with innovative solutions.
Beyond the desktop world, I build modern web solutions end to end: Node.js (Express / NestJS) for REST APIs, backend services and integrations, and React with Next.js for fast, responsive and SEO-friendly front ends. I work comfortably with TypeScript, JSON/REST APIs, authentication, and connecting these stacks to MS SQL Server, Oracle, PostgreSQL and MongoDB.
I also bridge legacy and modern systems - exposing data from Delphi applications through Node.js APIs and consuming them in React/Next.js or UniGUI front ends. A recent example is the UniGUI web application delivered for EDP LLC (USA) - linked in my portfolio - which lets clients modernise gradually instead of rewriting everything at once.
