Core Responsibility: Strategic Digital Transformation I specialize in auditing manual business workflows and architecting custom AppSheet and low-code solutions to digitize internal operations. My role extends beyond simple app creation; I manage the entire lifecycle of a client’s digital infrastructure—from initial requirement gathering and UI/UX design to long-term database maintenance and feature scaling. Key Areas of Impact ERP & POS Development: I build comprehensive management systems tailored to niche industries, such as luxury hospitality and retail. This includes developing integrated modules for Room Bookings, Restaurant Billing (POS), and Automated Invoicing, ensuring a seamless flow from customer interaction to financial reporting. Financial & Inventory Control: I implement robust logic for In-house Cash Management and Expense Tracking. By creating real-time inventory triggers, I help clients reduce waste and ensure stock availability through automated low-stock alerts and supplier integration. Human Capital Management: I design and maintain Staff Management and Payroll modules. These systems automate complex calculations involving attendance, shifts, and deductions, reducing administrative overhead and eliminating manual entry errors. Data Integrity & Maintenance: Managing internal operations requires high system reliability. I perform regular audits, optimize Google Sheets/SQL backends for speed, and ensure 100% data accuracy across all synced devices. Technologies & Methodologies Platforms: AppSheet, Google Workspace (Apps Script, Sheets, Drive), Looker Studio for data visualization. Approach: Agile development with a focus on User-Centric Design, ensuring that field staff (on mobile) and management (on desktop) have intuitive, high-performance interfaces. Outcome: My solutions have consistently resulted in higher operational transparency, allowing business owners to monitor real-time performance and manage assets remotely with total confidence
