Andrei Cioroianu

I am currently focused on building AI agents, RAG systems, and AI copilots that improve productivity and extend existing products. I continue to work on trading platforms and analytics systems, combining AI with my FinTech experience to deliver modern, reliable software. I design and build AI-powered features that automate workflows, enhance decision-making, and integrate intelligence into existing tools. My work includes AI agents, RAG systems, workflow automation, and custom copilots tailored to specific business needs. I combine AI development with full-stack engineering so I can deliver complete, production-ready solutions. I continue to develop trading software, including charting components, analytics applications, and workflow tools for traders and analysts. I integrate AI capabilities into these systems where appropriate, creating hybrid solutions that combine modern AI with proven FinTech functionality. I work across Java, Python, JavaScript, TypeScript, React, HTML5, CSS, SVG, and D3, with additional experience in C, C++, C#, Dart, and PHP. I deliver software deployed on Windows, Linux, cloud environments, and containerized systems. My focus is on reliability, maintainability, and practical engineering that supports the real-world adoption of AI.

I developed charting systems, trading platforms, algorithmic trading tools, and back-testing software across web, desktop, and mobile. I also led multiple migrations from Java to .NET and Java to Dart/HTML5, including responsive UI redesigns and mobile web interfaces. I implemented financial charting components, technical analysis tools, and trading UIs that interacted with data servers and back-end services. I built software products for back-testing and algorithmic trading, enabling users to create trading strategies through visual editors or JavaScript. I led several large-scale ports of commercial trading software from Java to .NET and from Java to Dart/HTML5. This included designing API mappings and implementing .NET and Dart equivalents of Java APIs used by the original software. These covered subsets of Java 2D graphics, AWT layout managers, Swing components, I/O classes, collections, and other core libraries. I modernized desktop UIs, making them responsive and migrating them to web and mobile environments. I worked with HTML5 Canvas, JavaScript, Dart, and related technologies to deliver fast, reliable, and user-friendly interfaces for traders and analysts. This period established my deep experience in trading software, charting systems, and cross-platform UI development.

I designed and built server-side frameworks, XML processing tools, and reusable components using Java and related technologies. My work focused on scalable back-end systems and developer productivity. I developed frameworks for XML parsing, combining SAX and DOM approaches to support high-performance processing of large documents. I created tools for mapping JavaBean objects to HTML forms and XML documents, improving consistency in server-side applications. I implemented reusable components, code generators, and productivity tools that helped teams deliver software faster and with fewer errors. I designed and implemented SaaS applications, websites, and server-side components using Java, JSF, JSP, ASP, PHP, and related technologies. My work included building custom tag libraries, web components, and integration layers for enterprise systems. This period established my foundation in full-stack engineering and long-term maintainability.

I wrote over 40 articles published by Oracle Technology Network (OTN), IBM developerWorks, O'Reilly ONJava, IDG JavaWorld, and Java Developer's Journal. I co-authored two books, namely Java XML Programmer's Reference and Professional Java XML, both published by Wrox Press. In 2004, OTN editors invited me to contribute to Oracle's Mastering J2EE Application Development Series. I shared the list of contributors with industry leaders like Rod Johnson (Co-author of Spring Framework), Craig McClanahan (Creator of Struts), and best-selling authors such as Ted Neward and Hans Bergsten.

I developed a CAD and 3D modeling product using Java 3D, implemented the 3D graphics engine for a chess game running as a Java applet, and created commercial desktop products based on Java and Swing. I also built a 3D game and 3D demos using C++.
