};I'm a Full Stack Web Application Specialist with over 25 years of hands-on experience spanning enterprise Java and modern JavaScript/TypeScript ecosystems. Known online as BalusC, I'm one of the most recognized voices in the Jakarta EE community.
As an Oracle Java Champion, Duke's Choice Award recipient, and the creator of OmniFaces (150K+ downloads/month), I deliver across the full stack — from Jakarta Faces, Lit, Vue.js, and TypeScript frontends to Jakarta EE, Spring, MicroProfile and Quarkus backends, and from greenfield *-as-a-Service (SaaS, PaaS, WaaS, etc.) builds to large-scale legacy migrations.
Battle-tested solutions for complex enterprise challenges
Building new web applications from scratch — Jakarta EE or Spring, or full stack combos with Node.js and web components in front of MicroProfile and Quarkus.
Large-scale migrations from RichFaces to PrimeFaces, Java EE to Jakarta EE, JSF 2.x to Faces 4.0, and Spring 5 to 6. 100K+ lines of XHTML migrated with OpenRewrite at the push of a button.
Vibe-coded a quick prototype that grew into a big ball of mud? I turn it into a real engineering asset — hardening security, scalability, and long-term maintainability.
Designing and implementing robust and secure RESTful and GraphQL APIs with Jakarta REST or Spring REST, backed by Jakarta Persistence, Hibernate and enterprise-grade databases.
Seamless integration with third-party APIs — e.g. payment processors (Sage Pay), identity verification (Okta, FusionAuth), mail services (Mandrill), cloud storage (S3), and many more.
Creator of OmniHai — a unified Java API for multi-LLM orchestration. AI-assisted development with among others Claude, GPT, Gemini, and Ollama to accelerate delivery.
Profiling and tuning sluggish applications — eliminating N+1 queries, adding caching and indexing, and re-architecting hotspots so the system scales under real-world load.
Comprehensive testing with JUnit, Mockito, REST Assured, Arquillian, Selenium, Mocha, and Playwright. Code reviews, written coding standards, and developer mentoring.
Producing clear technical documentation, written coding standards, and developer guides — from the Jakarta Faces book to the official Jakarta EE 10 tutorial for the Eclipse Foundation.
