A developer who sweats the details
I'm Teng Tjun Ong, a Customer Success Engineer at Jumio, driving post-sales integration and ensuring successful product implementation for clients.
With 4+ years of technical background spanning frontend development and enterprise support, I bring a unique perspective — I understand not just how to build features, but how they fail, and how to prevent that.
