Analytics Engine

Pemrosesan Event Throughput Tinggi & Dashboard Real-time

Analytics Engine - Pemrosesan Event Throughput Tinggi & Dashboard Real-time ANALYTICS ENGINE ENTERPRISE TELEMETRY & METRICS

Ringkasan Proyek

Platform pemrosesan data telemetri dan metrik keuangan berskala besar. Menerima aliran event transaksi secara masif dan menyajikan ringkasan visual real-time.

Tantangan

Sistem analitik berbasis batch processing lama mengalami keterlambatan hingga 4 jam dalam menyajikan data transaksi keuangan kritis kepada tim fraud dan operations.

Solusi & Arsitektur Teknis

Membangun pipeline event streaming menggunakan Go worker pools, Apache Kafka untuk ingestion queue, dan Redis time-series untuk agregasi data sebelum disimpan ke PostgreSQL.

Pipeline Ingestion Go dengan konkurensi goroutine tinggi memproses jutaan request stabil.
Dasbor telemetri interaktif dengan latency sub-detik untuk pemantauan live.
Sistem deteksi anomali otomatis yang mengirimkan peringatan instan saat terjadi lonjakan mencurigakan.
Arsitektur cloud terisolasi dengan auto-scaling berbasis beban lalu lintas.

Tertarik berkolaborasi atau mendiskusikan proyek baru?

Terbuka untuk kerja sama freelance, konsultasi arsitektur perangkat lunak, maupun posisi engineering.
