Summary
🤩
Rockstar🎓
Top SchoolSuleka Helmini is a Senior Software Engineer with eight years of experience building backend systems and compiler internals, currently enhancing data-driven products while pursuing an MSc in Applied AI at the University of Westminster. She has driven production features like a trading screener that improved analyst decision accuracy by 20% and architected Dockerized payment services with CI/CD automation. At WSO2 she owned complex compiler domains—adding 'group by' to Ballerina, resolving XML subtype inconsistencies, and fixing integer union type checking—demonstrating deep language and compiler expertise. An active open-source contributor, she has contributed to the core of the notable Ballerina programming language, focusing on diagnostics, type definitions, and runtime behavior. Her background blends ML research (publications and TensorMap work) with practical backend engineering, enabling her to bridge model development and productionization. Columbo-based and self-described as a "geek living in a constant paradox," she pairs rigorous engineering with a curious, mentorship-oriented mindset.
