Emmanouil Koukoularis

• Led the development team for the wwWallet platform (GUnet, Yubico, SUNET) in the SPRIND FUNKE international challenge, competing against and outperforming teams from Google and Samsung, resulting in a finalist/winner placement.

• Directed technical delivery across multiple EU Large Scale Pilots (e.g., DC4EU Social Security use case), coordinating with international partner teams on complex data-security and privacy-preserving systems.

• Proposed a mechanism for issuing multiple credentials of the same type filed as a spec issue, later adopted into the OpenID4VCI standard underpinning the EUDI Wallet ecosystem.

• Architected an event-sourcing session model for wwWallet, using map-reduce over base state and events to enable encrypted, cross-device session sync with conflict detection and resolution.

Built a multi-process system ingesting and processing large volumes of travel records, with TCP sockets and named pipes used for inter-process communication. Implemented multithreaded processing pipelines with low-level POSIX system calls, coordinating concurrent statistics computation across cooperating processes.

End-to-end compiler implementation for a subset of the Java language, translating source code into optimized LLVM IR. Used JavaCC to generate the lexer/parser and JTB to build the abstract syntax tree, then implemented semantic analysis and LLVM IR code generation.

• eClass Penetration Testing: Secured 1st place in an Attack-Defense simulation of 10 teams of the university; patched vulnerabilities and conducted penetration testing in a competitive format.

• Vulnerability Research & Exploitation: Engineered automated exploit scripts and documented solutions for a multi-stage Capture The Flag (CTF) security assignment focused on vulnerability research and penetration testing.

• Cybersecurity competition: Recognized for top-tier technical performance at the Belgium Embassy Cybersecurity Competition; successfully executed complex attack scenarios to achieve a leading position.
