Backend-focused Full-stack Engineer

Mario Prasetya Mulya

📍 Based in Indonesia

3-Years-Experienced Go, ReactJS, and .NET Developer.

My name is Mario Prasetya Mulya, a Software Engineer from Indonesia with a strong passion for Full-Stack Development. Currently, I work as a Senior Software Engineer at SINDIKA, where I lead end-to-end development of applications using ASP.NET (C#), ReactJS, TypeScript, and gRPC. I also mentor at BuildWithAngga and Eduwork, creating over 30 hours of Go-focused content and teaching 70+ live MERN stack sessions to students, many of whom have gone on to secure jobs in tech. These experiences reflect my dedication to sharing knowledge and building impactful software systems.

With over 3 years of experience, I've built and maintained software using Go, ASP.NET (C#), PHP Laravel, and PostgreSQL, and I'm also comfortable with front-end frameworks like JavaScript and ReactJS. I'm highly collaborative, adaptive to new tech stacks, and committed to delivering work on time with high quality. I've containerized applications with Docker, deployed them on VPS, and I'm actively deepening my expertise in distributed systems and AI.
I'm currently open to fully remote work opportunities, and I enjoy collaborating across time zones to build impactful, scalable software.

In my free time, I enjoy playing board games and Nintendo Switch, especially games that are fun and challenging. I also like reading tech books to learn more about software development and improve my skills.
