Layanan yang Pernah Saya Handle

"Omongan itu murah. Tunjukkan sistem production-nya." — Setiap Senior Engineer

Ini bukan daftar hal yang pernah saya "coba-coba." Ini adalah sistem production yang saya arsitekturkan, bangun, deploy, dan maintain — banyak di antaranya sendirian, kebanyakan masih berjalan sampai sekarang.

IoT & Fleet Management

Real-Time Fleet Telemetry

Skala: 50.000 events/detik, alert geofence di bawah 2 detik. Stack: Go, MQTT, Kafka, Time-Series DB, React dashboards. Dampak: Truck utilization 65% → 79%, fuel theft terdeteksi bulan pertama, hemat Rp 3.2 miliar/tahun. Baca case study lengkap →

Digital Mining Platform

Cakupan: Operasi tambang end-to-end — dispatch armada, fuel management, HSE digital, command center. Stack: Go microservices, React PWA, MQTT untuk edge-to-cloud sync. Dampak: Multi-site rollout (3 provinsi), real-time visibility dari lapangan ke HQ. Baca case study lengkap →

Fintech & Core Banking

Mobile Banking App — 680K+ Downloads

Skala: Zero downtime saat rush Lebaran (peak transaction volume). Stack: Go backend, Flutter mobile, ISO 8583 bridge ke core banking. Dampak: 680K+ Google Play downloads, integrasi mulus dengan mainframe legacy. Baca case study lengkap →

Platform Operasional Lapangan — 4.1M Nasabah

Skala: Dibangun sendirian dalam 30 hari, sekarang melayani 4.1 juta nasabah. Stack: Go monolith, Flutter mobile, offline-first sync engine. Dampak: Menghapus 23% data loss, simulasi IIR real-time untuk keputusan pembiayaan. Baca case study lengkap →

Cyber Insurance

Platform Asuransi — Perusahaan Asuransi Terbesar Australia

Cakupan: Full-stack cyber risk assessment → quoting → underwriting platform. Stack: Nuxt.js SSR, .NET microservices, Azure Cloud, UpGuard integration. Dampak: Digitalisasi seluruh siklus cyber insurance untuk IAG (ASX-listed, insurer terbesar Australia). Baca case study lengkap →

Education Technology

LMS — Single Codebase, Multiple Campuses

Cakupan: Technical assessment untuk unified Learning Management System melayani 100+ universitas. Stack: Architecture strategy — multi-tenant, white-label, single codebase. Dampak: Mendesain pendekatan untuk melayani institusi yang beragam dari satu artifact yang dapat di-deploy. Baca case study lengkap →

Technology Radar

Stack Saya

Primary: Go, Next.js, TypeScript, Flutter, PostgreSQL Messaging: MQTT, Kafka, RabbitMQ, NATS Infra: Docker, Kubernetes, Azure, GCP, CI/CD (GitHub Actions) Observability: Grafana LGTM, Prometheus, OpenTelemetry AI/LLM: Claude API, AI SDK, LangFuse, MCP orchestration

Cara Saya Bekerja

Discovery Dulu. Saya tidak mulai coding sebelum paham masalah, batasan, dan konteks bisnis.

Setiap engagement dimulai dengan architecture RFC sebelum implementasi apa pun.

End-to-End Ownership. Saya tidak hanya menulis kode — saya memiliki full lifecycle: design →

build → deploy → monitor → iterate. You build it, you run it.

Engineering Berbasis ROI. Setiap keputusan teknis terhubung ke dampak bisnis. Saya mengevaluasi

fitur berdasarkan switching costs, moat regulasi, dan margin operasional — bukan hype.

AI-Augmented, Bukan AI-Replaced. Saya memanfaatkan AI (Claude Code, MCP orchestration) untuk

melipatgandakan output 3x sambil menjaga standar arsitektur yang AI sendiri tidak bisa jamin.
