An engineer’s mind.
A builder’s curiosity.
I’m Edwin Andrianto, a backend engineer and Technical Lead at OCBC Indonesia, based in Tangerang. My work centers on the systems behind everyday experiences—and the people who build them.
My background spans financial applications, centralized onboarding, a Ruby on Rails to Java migration, and software for health records and travel. Outside that work, I share code experiments and practical technical notes.
