Erik Yuntantyo
Senior Software Engineer
Senior Software Engineer, backend-focused — 10+ years in the engine room. I've shipped logistics SaaS and fintech payments for CDAS (Singapore), delivered public-service tools for SG Enable, and built a confidential Tier-1 Singapore government platform under NDA. My job is to bridge business logic to the servers that run it: architect backends that scale, debug the ones that don't, and ship clean, well-tested code. Fully remote. Zero hand-holding required.
How I Work
Three commitments you can hold me to on every team I join
I architect
I start from the business problem, not the framework. You get a system designed to scale and survive production — not a prototype that buckles under real load.
I own the pipeline
Code to cloud is mine end to end. I set up CI/CD, infrastructure, integrations, and monitoring, then answer for reliability when it counts. No throwing it over the wall.
I mentor
I level up the team as I ship — code reviews, pairing, and clear standards — so the codebase stays maintainable long after I move on.
