Professional Summary

Technology executive with 18+ years leading enterprise IT, application services, and digital operations across large-scale, multi-outlet Food & Beverage, Retail, and Entertainment businesses spanning Indonesia and international markets. As Group Head of IT at Sour Sally Group, runs application support, project delivery, infrastructure, and security for 500+ outlets across Indonesia and Dubai with a lean 5-person team — proof of doing more with less through automation and strong systems. A rare full-stack technologist who commands the entire stack end-to-end — solution architecture, front-end & back-end development, system & enterprise integration (SAP, ESB, ERP, APIs), cloud, networking, infrastructure, security, and AI. Personally designed, built, integrated, and operated karyaOS — a production operational-intelligence platform — single-handedly, from code to infrastructure.

Key Achievements

  • Run IT & application services for 500+ F&B and retail outlets across Indonesia and Dubai with a lean 5-person team — a high-leverage, automation-first operating model.
  • Architected karyaOS end-to-end — POS, Kiosk, KDS, inventory, procurement, CRM/loyalty, and executive BI dashboards with AI-driven anomaly detection.
  • Built a Vista-grade cinema performance & finance suite in karyaOS — full box-office analytics, film-hire / distributor settlement, per-outlet P&L, and a 6-month trend engine with automated insights — drawing on years running Vista at Platinum Cineplex.
  • Designed, built, and operated Desa Nusantara — a national village-tourism & UMKM marketplace — single-handedly: Midtrans split-payment revenue-sharing (85% artisan / 10% village BUMDes / 5% platform), a full admin CMS & control center, GPS + WhatsApp-OTP onboarding, bilingual SEO with dynamic share cards, and interactive maps.
  • Conceived and shipped WORKD — a swipe-to-hire recruitment platform — as a lean in-house alternative to a Rp 5.7 billion external investment proposal, delivering a working production product in days: AI candidate matching, instant match, real-time chat, Web Push, Midtrans subscriptions, and an installable PWA.
  • Spun out multiple standalone SaaS product lines from the karyaOS core — Tertib (SOP & compliance), SiteDev (expansion lifecycle), Pantau (CCTV-AI monitoring), Tayang (digital signage), and WORKD (recruitment) — each with its own tenant signup, pricing tiers, and subdomain, all reusing shared auth · payments · AI · infrastructure.
  • Delivered SAP and ESB integrations connecting POS, ERP, and operational systems, giving leadership reliable, near-real-time visibility across the network.
  • Support multi-country expansion — live operations in the UAE, with India and the Philippines next.
