Herin — Personal OS

Hello|
I'm Herin Yudha Pratama

I ship apps, dashboards, WhatsApp automation, AI agents, and ad systems — 14 years on the commercial side, over $1M in paid ads at a 15–20× average ROAS.

Based in Bandung, working everywhere.

I spent fourteen years on the business side — founding AS GOOD SUPPLY CO and running it for nearly a decade, then leading commercial at consumer brands, running the full org: offline stores, online store & marketplace, digital marketing, CRM, KOL, and content teams.

Performance marketing is home ground — over a million dollars deployed across Meta, Google, TikTok, and Shopee ads at a 15–20× average ROAS. Somewhere along the way I started building the systems my teams needed, and never stopped.

Today I build operational software: ERP and accounting platforms, WhatsApp commerce, dashboards, and AI agents that work around the clock. My approach is simple — understand the business flow first, then write the code. The tools change; the goal doesn't: systems that quietly do their job every day.

App 01 — ERP & Accounting

Your spreadsheets disagree with each other. This is what replaces them.

One entry moves stock, posts the journal, and lands in your P&L — automatically, every time. The full chain is here: sales order → delivery → invoice → payment, purchasing → goods receipt → vendor bill, inventory with batch and expiry-first (FEFO) logic across multiple warehouses, tax-ready invoicing, QR-coded delivery notes, and the reports your accountant actually signs off on — trial balance, P&L, balance sheet, every number traceable to its journal entry. The same engine runs real distribution companies in production today, multi-tenant with role-based access. Built by someone who ran operations for 14 years before writing the software — so it follows how your business actually works, not how a template thinks it should.
