Infraware

Principal Developer

Infraware was a software asset management consultancy where I mostly worked on SAMSentry, a web app for ITIL-based software asset management reviews. I built it from scratch full stack JavaScript (CI/CD on Azure) based on internal consultancy expertise and feedback from corporate clients. It was eventually bought by SoftwareONE, a large multinational.

SAMSentry is a unique solution. It’s a visual dashboard of maturity assessments combined with industry insights, project tracking and recommendations. It is a unique and compelling solution in the market, and we are thrilled to be able to offer it to our customers.
