Software Engineer · Backend & Platform

Building reliable systems that keep operations moving.

Hi, I’m Muchamad Fauzy — a backend-leaning software engineer who collaborates with product and operations teams to ship resilient APIs, integrate external services, and translate business rules into dependable software. From port automation to project monitoring suites, I focus on giving operators real-time confidence in the systems they rely on, while staying comfortable owning frontend and full-stack delivery when teams need it.

About

Engineer focused on resilient platforms

I partner with product, ops, and infra teams to translate evolving requirements into maintainable backend or frontend solutions. I enjoy aligning constraints, keeping feedback loops short, and documenting decisions so teams can move faster with confidence.

My toolkit spans TypeScript, React, Golang, NestJS, Next.js, relational databases, message-driven patterns, and more. Lately I’ve paired secure access control at the JIIPE special economic zone with a project monitoring platform that connects React dashboards to Golang services.

Beyond feature delivery, I invest in developer experience—strengthening API contracts, shaping reusable UI patterns, and documenting decisions so teams can move faster without fire drills.

Experience

Delivering complex integrations with confidence

From logistics checkpoints to dashboards for payroll and project monitoring, I build the foundations that let teams launch features quickly, stay compliant, and keep data flowing between systems.
