Built with technology.
Learned on the ground.
I look for answers where
the software is actually used.
My work in Indonesia has spanned online game operations, running local companies, software development, and technical support. I have built systems and worked to keep them running well in practice.
From engineering to local business
Through company operations and product development at Teracord, Jiran Tech Indonesia, and Neonesia, I worked on both technical and business challenges.

Have a project
in mind?
Tell me about a service you’d like to build or a problem you’d like to solve.
Alongside more than a decade of on-the-ground experience in Indonesia, I’ve worked in Brazil and Canada and studied Spanish in Medellín, Colombia. For international projects that call for an understanding of different cultures and local conditions, I’d like to draw on these experiences to find practical solutions together.
I work on projects in the evenings after my day job and on weekends.
Please keep this in mind when proposing a timeline and scope.
