Software Builder · Custom Business Systems · Indonesian SMEs

I help Indonesian SMEs replace chaotic operations with custom software, built one-on-one and hands-on. The kind of business whose operations have outgrown spreadsheets but where a generic ERP feels too rigid for how the team actually works.

My work turns manual processes into structured ones: visible to managers, controllable through approval flows, and reliable enough to run a daily shift on. Two years of ops coordination ran in parallel with my CS studies, so when an owner explains a margin, stock, or late-payment problem, I don't need it translated. The hardest part is rarely the code. It's mapping the actual workflow honestly, then deciding what's worth automating and what isn't.

Recently, I've worked on:

  • Custom dashboards mapped to how the team actually works
  • Pricing and operational logic for retail/wholesale workflows
  • Secure multi-user systems with row-level access control
  • AI-assisted tools for content and internal operations

OMNICHANNEL RETAIL ERP

Client: INTERNAL RETAIL CLIENT

Problem:Marketing and supply chain teams were managing daily data entry and channel pricing across broken spreadsheets.
Solution:Built a custom dashboard using Next.js Server Actions and Supabase. I wrote atomic database RPCs to stop inventory race conditions. The system includes a fiscal calendar engine for reporting. Role-Based Access Control (RBAC) keeps staff and dealer data strictly isolated.
Result:Zero inventory mismatches across 1000+ SKUs and multiple stores. Reports in seconds. Full audit trail on every transaction.

RUANGKONTEN — AI CONTENT STRATEGIST

Client: PERSONAL SAAS PRODUCT · Status: In Development

Problem:Founders and creator-operators have to write the same topic in three account voices, schedule across time zones, avoid duplicate posts, and learn from what works. All manually.
Solution:A multi-tenant content workflow with AI that learns from every post. Funnel-aware generation (TOFU/MOFU/BOFU), anti-duplicate fingerprinting with a 60-day memory window, per-org Threads OAuth encrypted via Supabase Vault, and a Pro-tier coach trained on real customer data instead of generic advice.
Result:One topic generates three voice-tailored drafts in under 30 seconds. Lifecycle (DRAFT, SCHEDULED, READY, POSTED) is fully audited. The 60-day fingerprint window catches accidental reposts before they ship.
