- 📚 engineering-library — Production-grade Java 17 / Spring Boot 3 monorepo featuring 90+ multi-tiered reference implementations (
nanotomacro), 13 knowledge domains, ADRs, and post-mortem analysis. - 🔀 bpmn-provisioning-patterns — Executable Camunda + Spring Boot + Kafka Sagas modeling telecom provisioning, multi-operator number portability with SLA timeouts, and threshold-based batch compensation.
- 🛠️ keycloak-spi-workbench — Real-world Keycloak SPI extensions (Custom Authenticators, Event Listeners, Federation) built properly with full integration test coverage.
- 🔐 spring-keycloak-toolkit — Enterprise Spring Boot auto-configuration library for Keycloak OAuth2/OIDC Resource Servers, solving role-mapping and RFC 7807 problem details.
- 🤖 ai-skills — Pragmatic AI Engineering Knowledge Base (LLM Economics, Hybrid RAG, Multi-Agent Orchestration, MCP Protocol, Spring AI & Guardrails) powered by JihedAiLabs.
- 🛡️ cyber-skills — A working library of security skills across 26 domains — each an agent-ready SKILL.md that doubles as a human cheatsheet. Bilingual EN/FR.

- From Spring Boot to Spring Cloud: Master microservices architecture, from design to production.
- Keycloak Security Mastery: Understand and extend Keycloak (SPI), integrate OAuth2/OIDC with Spring.
- Orchestration & Resilience (BPMN): Manage distributed transactions, saga patterns, and system resilience.
- Applied Enterprise AI: Integrate Generative AI into existing production workflows (RAG, Agents, Spring AI).
- Standardization and CI/CD: Implement code governance, quality gates, and advanced CI/CD.
Engineering is not just about writing code; it is primarily about managing complexity. I strongly believe in simplicity by design (clean architecture), secure-by-default paradigms, and validation through execution rather than theory. A distributed system must be designed to fail predictably, with clear boundaries and total observability. My approach prioritizes production reliability, relentless automation, and transparently sharing field-tested knowledge.
