Backend Engineer • Systems Engineer • Infrastructure & Network Specialist

Backend and systems-focused engineer with a strong inclination toward infrastructure-aware backend design, network-centric system behavior, and Linux-based service reliability. Experienced in working close to the system layer, where connection stability, resource efficiency, and predictable behavior under continuous load are more critical than surface-level features. Comfortable operating independently and building solutions that are meant to run long, stay stable, and fail gracefully.

Engineer backend dan sistem dengan fokus kuat pada desain backend yang sadar infrastruktur, perilaku sistem berpusat pada jaringan, dan reliabilitas layanan berbasis Linux. Berpengalaman bekerja dekat dengan layer sistem, di mana stabilitas koneksi, efisiensi resource, dan perilaku yang dapat diprediksi di bawah beban kontinu lebih penting daripada fitur permukaan. Nyaman bekerja secara mandiri dan membangun solusi yang dirancang untuk berjalan lama, tetap stabil, dan gagal secara terukur (graceful).

Currently open to work for backend, infrastructure, systems, or reliability-focused roles. Saat ini terbuka untuk peluang kerja di bidang backend, infrastruktur, sistem, atau peran yang berfokus pada reliabilitas.

Web hasil dari Apiku dengan konfigurasi yang lebih lengkap dan diperluas.

• autoscript - Automated server provisioning, setup, and configuration scripts.
• mt7902-driver - Low-level hardware driver implementation for MT7902.
• apiku - Core API utility and automation toolkit.
• marzban - Proxy management and infrastructure integration.
• wa-bot - Automated WhatsApp interaction and routing service.

• Prefer simple, understandable systems over opaque abstractions. Mengutamakan sistem yang sederhana dan mudah dipahami daripada abstraksi yang rumit.
• Stability and predictability are features, not afterthoughts. Stabilitas dan prediktabilitas adalah fitur utama, bukan tambahan.
• Systems should degrade gracefully, not fail catastrophically. Sistem harus mengalami penurunan fungsi secara terukur (graceful), bukan gagal secara katastropik.
• If a system runs unattended, it must be observable and controllable. Jika sebuah sistem berjalan tanpa pengawasan, sistem tersebut harus dapat diobservasi dan dikendalikan.
