CV

I am a software developer and a former database researcher whose passion is building data-intensive applications.

I have a strong foundation in data and database with overall 8 years of hands-on experience in database theory and in implementing database kernel components: indexing, storage, and query processor.

I earned a PhD degree in Database Technology and a Master degree of Computer Science both at Uppsala University, Sweden. Among other research works, I have some research publication that contributed to the foundation of StreamAnalyze AB, which provides edge computing or analytic engine.

Prior to this, I had started my software developer career since 2005 primarily developing desktop applications and web applications.
