Hi, I'mSanudin👋
A software engineer, frontend enthusiast, and lifelong learner
Most at home building backend systems, but care deeply about how things look and feel on the surface
👨🏼💻
About
I'm a software engineer based in Indonesia, working across the full stack but most at home on the backend — designing APIs, structuring data flows, and solving problems where the requirements are concrete.
I've spent the last several years at a Singapore-based fintech platform, working on complex API integrations, legacy codebases, and system architecture.
Outside of work, I'm learning Python, exploring distributed systems, and writing about what I learn.

Experience
Senior Software Engineer at AutoWealth, a Singapore-based fintech platform. Working across the stack — from legacy PHP codebases to complex API integrations, system architecture, and frontend implementation — including writing a custom PHP connector to fix a security issue in our MyInfo (NDI) implementation — and taking full ownership of features from planning to production.

REST: The API Style Everyone Uses
REST is everywhere, but most "REST APIs" quietly break its own rules. This article breaks down what REST really requires (including the HATEOAS rule almost everyone skips), the difference between safe and idempotent HTTP methods, why idempotency is what saves you from double-charging a customer on a flaky connection, resource naming conventions, statelessness, and the status codes worth actually knowing.
#api#webdev#backend#beginnersWhat Is an API, Really?
APIs are everywhere — but what actually is one? This article breaks down what an API really is, how the client-server request-response cycle works, HTTP fundamentals, the difference between sync and async communication, and why API design matters from day one.

Git doesn't have to be scary. In this first part, we break down what Git is, what a repository is, and how commits work — using everyday analogies simple enough for anyone to understand.
