Introduction Introduction

Hi, I'm Izal Fathoni. I'm a Full Stack Engineer with over 6 years of experience in software development.

Throughout my career, I've had the opportunity to work with a variety of technology stacks, which has sharpened my ability to learn quickly and solve problems from multiple perspectives. I'm always looking for ways to grow my skills and love jumping into collaborative projects where we can build software that actually solves real problems for users and the business.

Outside of my day job, I'm usually building tools to make the developer experience better. I like looking back at the headaches I've faced in past projects and creating side tools that simplify the workflow, building the things I wish I'd had at the time.

With my full stack capability and cross-industry experience, I'm ready to help your company accelerate development, maintain product quality, and deliver the right technical solutions. I'm also comfortable working independently or collaborating within a team, and can quickly adapt to new environments and tech stacks.
