Agentic AI Architecture & Governance
Design and implementation of agentic AI platforms including multi-agent workflows, role-based agents, tool adapters, MCP, context engineering, hooks, skills, evals, human approvals, PII controls and governance-by-design patterns such as human-in-the-loop, policy gates and review traceability.
Enterprise Java Architecture
Architecture and hands-on engineering of mission-critical Java systems using Spring Boot, Jakarta EE, EJB, JBoss EAP, Hibernate/JPA, REST/SOAP, JMS, Oracle, Maven, Liquibase, Docker, CI/CD, OAuth2/OIDC and SAML across public-sector and financial institutions.
Secure Integration & AI Governance
Implementation of tool controls, validation gates, adversarial review patterns, least-privilege MCP access, sanitized-context boundaries, PII safeguards and constrained vendor/model use to ensure secure enterprise AI delivery.
Distributed Execution & Agentic SDLC
Connection of product, architecture, engineering, QA, security and DevOps roles through controlled handoffs, human approvals and review evidence; agents operating in IDE/CLI/CI environments with approved vendor routes.
GitHub Copilot, Cursor & Claude Code Integration
Design of integration patterns for GitHub Copilot, Cursor and Claude Code, demonstrating workflows from Atlassian Rovo, Jira and Confluence through to implementation.
OAuth2, SAML & Identity Management
Architecture and delivery of enterprise identity management solutions using OAuth2, SAML and OpenAM, including secure REST, JMS and SOAP integrations with OAuth2-based security.
CI/CD & DevOps Quality Controls
Design and implementation of CI/CD pipelines, quality controls and modernization initiatives across Spring Boot, JBoss EAP and Docker environments for high-reliability public-sector platforms.
Hybrid & Sovereign AI Gateway Architecture
Definition of hybrid gateway and sovereign/on-premise reference options as future evolution paths for enterprise AI platforms, distinct from currently delivered capabilities.
Oracle & Database Integration
Design of Oracle persistence layers, secure REST services and asynchronous integration patterns for tax-administration and enterprise Java services spanning regulatory logic and REST APIs.

Project history
Designed and implemented Qantora, a reusable, versioned harness of agents, skills, instructions, workflows, hooks and quality gates. Enabled distributed execution in IDE/CLI/CI environments, connected product, architecture, engineering, QA, security and DevOps roles through controlled handoffs, and implemented governance controls including tool controls, validation gates, adversarial review patterns and least-privilege MCP access.
Architected complex tax-computation services for Abraxas Informatik AG, Switzerland, across multiple cantons with high reliability, security and maintainability requirements. Led Java/Spring Boot/JBoss EAP upgrades and designed secure REST services, Oracle integrations and CI/CD quality controls.
Architected tax-administration Java services for Abraxas Informatik AG, Switzerland, spanning regulatory logic, REST APIs, asynchronous integration and Oracle persistence. Improved security and maintainability across Spring, Hibernate, JBoss EAP, Maven and Docker.
