● TERSEDIA UNTUK BEKERJAStaff Software Engineer & Fullstack Developer
Spesialisasi dalam menjembatani antarmuka pengguna yang reaktif dan interaktif dengan layanan backend terdistribusi berlatensi rendah, streaming pipeline throughput tinggi, dan otomasi engine settlement FinTech yang konsisten.
Carrier-Grade OSS/BSS & ERP
Manajemen operasional ISP end-to-end: Sales Order SPK terotomasi dengan reservasi port ODP 24 jam via Redis, validasi cakupan geospasial real-time PostGIS (GiST R-Tree sub-5ms), isolasi cabang multi-tenant berbasis RBAC (Role-Based Access Control), dan manajemen tiket gangguan pelanggan CS berbasis kategori masalah dengan pelacakan batas SLA.
FinTech & Multi-Payment Gateway
Routing agregasi multi-gateway (Midtrans, Xendit, Mandiri VA, QRIS), rekonsiliasi settlement otomatis dengan pembukuan double-entry zero-variance, serta distributed idempotency lock via Redis Redlock (500+ webhook simultan tanpa race condition).
B2B IPTV & Scoped Content Platform
Platform IPTV komersial multi-tenant untuk sektor hospitality dengan RBAC bertingkat (Superadmin, Property Manager, Frontdesk) yang terikat langsung ke kontrak langganan, isolasi konten per properti, serta append-only audit trail di MongoDB.
Sistem Terdistribusi & Rate Limiter
Microservices berkonkurensi tinggi dengan Go dan NestJS, algoritma distributed sliding-window rate limiter via Redis Lua script atomik berlatensi sub-milidetik, arsitektur event-driven broker (Kafka, Redis Streams), dan komunikasi gRPC efisien.
Penyimpanan Objek & Presigned Upload
Arsitektur direct-to-storage presigned URL dua fase (Two-Phase Quota Locking) di Go untuk transfer file berukuran gigabyte, integrasi Cloudflare R2 zero-egress, pencegahan buffer overflow server, dan verifikasi checksum SHA-256 ketat.
Multi-Tier Caching & UI Reaktif
Rekayasa UI modern reaktif dengan Server Components (RSC) dan Server Actions, topologi caching 4-tier (Server Data Cache, Full Route Cache, Router Cache, IndexedDB Offline Cache), kanvas diagram SVG interaktif dengan zoom/pan, dan skor Lighthouse 99+.
Automasi CI/CD & Container Registry
Arsitektur pengiriman kode otomatis end-to-end: Verifikasi quality gate (type check, linter, tests), build container multi-stage Docker teroptimasi dengan cache GitHub Actions, publikasi image ke GitHub Container Registry (ghcr.io), retensi/prune versi container otomatis, serta deployment zero-downtime ke server VPS via SSH remote execution.
