## Case Studies
In-depth write-ups of products built and shipped, at https://bintangtobing.com/case-study

### PMHelper — running a whole team from one tool
https://bintangtobing.com/case-study/pmhelper
Forked an abandoned open-source project and rebuilt it into a production project-management system: six database-driven roles, a QA-gated ticket pipeline with 15 statuses, auto-generated daily/weekly reports, an OKR/KPI module (objective weight x key-result weight x score), a React Native app (Expo, 37 REST endpoints), and a Claude MCP server (14 permission-checked tools). Five users depend on it daily at pm.cirrus-hub.net. Stack: Laravel 9, Filament v2, PHP 8.3, Livewire + Pusher, MySQL.

### Bitunix MarTech Dashboard — running marketing from one screen
https://bintangtobing.com/case-study/bitunix-martech-dashboard
Replaced an hour of daily spreadsheet work with one dashboard that joins Google Search Console, GA4, and the Bitunix Partner Portal into a single conversion funnel (impression to first trade). Attributes deposits (not clicks) to campaigns, and cut brand-traffic dependence from 71% to 58% in a quarter. Daily sequential refresh at 02:00/02:30/03:00. Stack: Laravel 13, Next.js 16, PostgreSQL, Redis, BigQuery.

### KlindrOS — three products on one marketing engine
https://bintangtobing.com/case-study/klindros
One data pipeline and one 0-100 KEI scoring framework power three products: Core (a Bloomberg-terminal-style platform for brand teams with multi-touch attribution, autonomous optimization, and an Organic Fatigue Index), KScore Business (a two-minute single-account sales scan), and KScore Personal (a three-minute personal-brand audit across six platforms with the Klaira AI strategist). Honest unit economics: ~$0.08 per personal scan, logged per event. Multi-tenant, Laravel 11 + Next.js 16 + Expo.

### KlindrOS CRM — turning a stranger into a paying tenant
https://bintangtobing.com/case-study/klindros-crm
The sales engine behind the scans: a single-tenant Filament admin at /crm. Four lead doors (KScore Business, KScore Personal, Calendly, Ghost blog) into one workspace, two-way email over IMAP (reply polling every two minutes, header-based thread matching), Calendly webhook write-backs, a one-click Convert-to-Customer that provisions a live tenant, and a Ghost CMS blog wired in via HMAC-verified webhooks so content and sales share one engine. Stack: Laravel, Filament, IMAP, Calendly, Ghost Content/Admin API, GA4.
