Dataverse

I actively contribute to Dataverse, an open source research data repository software. I am mainly focused on re-architecture matters. In particular, the decoupling of the frontend and migration to a React SPA, in addition to other topics such as authentication redesign, API extension, and containerization.

Elitenics

Elitenics

I built Elitenics from the ground up—starting with shaping the initial concept and designing the UX/UI, through to development, testing, and launching the app, while also developing the overall business strategy. As the project gained traction, I expanded the team. Since launch, we’ve iterated continuously based on user feedback and business insights, evolving Elitenics into a scalable and sustainable business.

Disturb

Disturb

At Disturb, we believe the best products come from real synergy — passionate people, diverse talents, and a shared sense of purpose. We're a product engineering brand that goes all-in on what we build — with creativity, precision, and heart. And if things don't go as planned? We learn, we adapt, and we come back stronger. That’s why we never fail. Only grow.
