I help businesses automate their workflows using Google Sheets, AppSheet, Apps Script, and custom Chrome Extensions. If your operations still rely on manual spreadsheets, repeated copy-paste, or slow admin processes, I turn them into fast, reliable, and scalable systems. What I build: - Google Sheets automation (validation, reports, dashboards, multi-sheet syncing) - Apps Script development (API integrations, schedulers, PDF generation, triggers) - AppSheet apps (mobile forms, approval flows, attendance, timesheets, inventory) - Chrome Extensions (MV3, UI injection, automations, productivity tools) My approach: - Understand your workflow and pain points - Design a clean, simple, sustainable solution - Build with reliability, scalability, and long-term maintainability - Provide clear communication, documentation, and support I specialize in real business automation, not just coding helping clients reduce manual work, eliminate errors, and improve productivity with tools that are easy for teams to use. If you need a developer who can translate ideas into working systems quickly and professionally, I’m here to help.

I transform manual, fragmented workflows into reliable, automated systems. Most businesses don't need complex new software. They need their existing data, tools, and AI to work together. I bridge the gap between "just a spreadsheet" and a fully functional internal tool that scales. 🚀 What I do for my clients: Finance & Data Centralization: Turning multiple disconnected sheets, QuickBooks records, or files into a single, automated "source of truth." AI & LLM Integrations: Connecting tools with AI APIs (OpenAI, Anthropic, Grok) to automate smart data extraction, categorization, or lead scoring. Internal Web Apps: Creating easy-to-use interfaces (AppSheet) so non-technical teams can manage data without breaking the underlying logic. Workflow Automation: Building bulletproof pipelines using n8n, Make, and Zapier so data flows seamlessly. 🛠️ Tech Stack: Automation Engines: n8n, Make, Zapier. Google Ecosystem: Apps Script, AppSheet, Advanced Sheets. Custom Development: Python (Upwork Certified), REST APIs, Data Scraping, JSON/PDF parsing. My goal is to make your operations invisible and error-proof, so you can focus on growing your business instead of managing files. 👉 Send me a message describing your current manual process, and I’ll design an automated solution for you.
