I am a Backend & Network Engineer based in Tuban, Indonesia, bridging the gap between high-level application development and low-level network operations. I specialize in building robust web applications, designing scalable backend systems, and securing Linux infrastructures.

I am passionate about engineering practical solutions that solve real-world problems. My expertise spans across the entire stack—from crafting RESTful APIs and managing databases to configuring firewalls, analyzing packets, and deploying automated network infrastructures.

🎯 Core Competencies:

• Backend Engineering: Developing scalable APIs, microservices, and business logic.
• Network & Security: Firewall configuration, DNS filtering, packet analysis, and secure routing.
• Infrastructure & DevOps: Linux system administration, containerization (Docker), and automation scripting.
• Full-Stack Delivery: Integrating seamless frontend experiences with powerful backend architectures.

Currently, I am expanding my expertise in Network Security, Infrastructure Automation, and Cloud/On-Premise Deployments through hands-on enterprise projects and self-hosted environments.
