Portunus is a novel Identity and access management platform that I designed and built over three years as a side project.

I took the platform from early sketches of workflows, through three iterations of architectural changes and optimizations, to a public tech demo hosted on AWS. The project encompasses technical documentation, front-end development, continuous integration, containerization, scaling, database query optimizations, and tech stack (Redis/PostgreSQL/Celery/Django) and capabilities optimization of available libraries in tandem.

A PaaS solution for data analysis built for the European Space Agency.

I operated as the solution architect and lead developer (as well as wearing many other hats). I took GAVIP from early sketches on post-it notes to a complete platform deployed in the ESA data center in Madrid and delivered ahead of time ( around 15%).

The platform was required to support processing over 1PB of data and allow custom code to be contributed and shared among scientists with minimal manual intervention. I worked with multiple teams distributed across Europe to handle many different use-cases, from machine learning to interactive visualization of our galaxy.

A platform designed to replace repetitive efforts in reporting within a large enterprise organization. Reporting is a critical need in large businesses, and I found a cost being accumulated in maintaining many one-off reporting tools and scripts.

So I designed, built, deployed, and got sign-off on a platform that allowed operators to add custom reports with credentials securely managed in Vault.
It helped save a lot of human hours each week and reduce the exposure to human error in critical reports.
