Cover image for Larisio — Multi-Platform POS &

Larisio — Multi-Platform POS & Retail Management SaaS Larisio is a multi-platform POS and retail management system designed for businesses that need reliable daily operations, centralized inventory control, and flexible access across multiple devices. I built the platform to handle point-of-sale transactions, product and category management, stock monitoring, purchasing, customer management, transaction history, and business reporting from one centralized dashboard. The system follows an offline-first approach, allowing essential operations to continue even when internet connectivity is unstable. Once the connection is restored, locally queued transactions can be synchronized back to the central PostgreSQL database. Larisio also supports multi-outlet operations, role-based access, subscription billing, and deployment across web, Windows desktop, and Android.

Cover image for Maintenance Inventory Management System —

Maintenance Inventory Management System — PT Daiki Aluminium Industry Indonesia I designed and developed a maintenance inventory management system for internal spare-part operations at PT Daiki Aluminium Industry Indonesia. The system was created to improve visibility and traceability of maintenance spare parts, especially for stock-in, stock-out, stock opname, item searching, and transaction history. I implemented QR-based item scanning, inventory transaction tracking, audit records, and a hybrid offline-online workflow so operations can continue when network connectivity is limited and synchronize with the main database when connectivity is restored. The project was built around real manufacturing and maintenance workflows, with the goal of reducing manual recording, improving stock accuracy, and making spare-part movement easier to monitor.

Wassie — Discord & Web3 Automation System Wassie is a private Web3 Discord automation project I built to support community operations, alerts, and engagement workflows.

The project includes custom bot automation, NFT and market activity alerts, wallet/whale tracking, role-based server organization, and operational monitoring workflows to help the community stay organized and informed in real time. My role covered both the Discord server architecture and the automation/backend integration behind the system.

Cover image for OpsPilot — AI Business Operations

OpsPilot — AI Business Operations Dashboard OpsPilot is an AI-powered business operations platform designed for creative agencies, studios, and freelancers to manage clients, deals, projects, invoices, and financial workflows from a single workspace. I designed and developed the platform as a full-stack application, combining CRM functionality, automated invoicing, business analytics, and an AI assistant that can answer operational questions using real business data. Key capabilities include client and deal management, branded PDF invoices, recurring retainers, automated payment reminders, revenue and accounts receivable tracking, pipeline analytics, multi-user workspaces, and AI-powered business insights. The goal was to reduce the fragmented workflow of managing clients in messaging apps, invoices in spreadsheets, and business data across multiple tools by bringing the entire operational workflow into one integrated system.

Cover image for This tiny Apps Script can

This tiny Apps Script can turn a Google Sheet into an automated notification system. One of the simplest automations I use: Google Form ↓ Google Sheet ↓ Apps Script ↓ Automatic email notification Instead of checking the spreadsheet manually every time a new lead comes in, the workflow can trigger an email automatically. The interesting part? You don't need to build a complicated SaaS to automate a repetitive task. Sometimes, a few lines of Apps Script are enough. I use this approach as a foundation for larger Google Workspace automation systems. What repetitive task would you automate first with Google Sheets?

From Spreadsheet Chaos to Automated CRM System. Most businesses don't need more tools. They need better workflows. Many small businesses still manage customer data manually: ❌ Leads scattered across multiple spreadsheets ❌ Follow-ups forgotten ❌ No clear sales pipeline ❌ Customer history difficult to track This is where automation can help.

No complicated software. No unnecessary subscriptions. Just a workflow designed around how your business actually works. Building practical automation systems for businesses using Google Workspace. What process in your business takes too much manual work?
