I'm Kelvin Sidharta Sie, a software engineer based in Surabaya, Indonesia. I specialize in backend development with a strong foundation in microservices architecture. I also show interest to full-stack, AI, and DevOps engineering.

I previously worked at @BCA, where I developed REST API and microservices features for treasury's API foreign exchange system. From this experience, I became passionate about building backend systems as it broadens my view on large scale and resilient system design

I am currently working as a part-time in @OMNI Surabaya, developing backend systems using Laravel and websites for clients needs using Vue.js.

Outside from engineering stuffs, I used to take part in organization events during my college time to improve my soft skills in communication, team work, and time management. I started being a member, then chairman, then I became Secretary in Informatics Student Union @PCU.
