ABOUT

Engineering beneath the application layer.

I spent five years shipping production FinTech systems while completing a First Class Honours degree — and used the hours in between to build open-source frameworks and teach engineering to the next generation of students.

My focus is framework engineering: not writing applications, but building the layer beneath them. The research form of that work was presented as a first-author paper at ICCTA 2026 in Vienna. Its open-source form is Wolfigs — developer tooling engineered in Sri Lanka for a global audience.

RESEARCH

Published at ICCTA 2026, Vienna

"FractalX: Automated Migration of Modular Spring Boot Monoliths to Production-Ready Microservices via AST-Driven Static Decomposition"

First author · 12th International Conference on Computer Technology Applications (ICCTA 2026) · FH JOANNEUM, Vienna, Austria · May 2026

Deferred architectural decomposition carries a well-documented industry cost. FractalX addresses it directly: an AST-driven framework that statically decomposes modular Spring Boot monoliths into production-ready microservices. The research line continues as Prism, its open-source successor.
