Hi there, I’m Luis. I build spreadsheet automations with VBA and AppScript, custom web applications, and internal tools that help businesses reduce manual work and improve operations. I work with companies that are using Excel, Google Sheets, macros, manual reports, or outdated workflows that no longer scale. Sometimes the right solution is improving the spreadsheet. Other times, it is turning that spreadsheet or macro-based process into a full web application that is easier for a team to use, manage, and grow. I can build web apps from scratch, or I can take an existing Excel, Google Sheets, VBA, or Google Apps Script system and rebuild it as a modern web application with user access, dashboards, forms, database storage, automated workflows, and reporting. I’m also the creator of CSVLink App and StructaCAD, two automation-focused software products built to solve real operational problems. What I Can Help With • Excel and Google Sheets automation • VBA and Google Apps Script development • Converting spreadsheets and macros into web applications • Custom internal tools for daily operations • Business web applications built from scratch • API integrations and third-party system connections • Automated reporting and document generation • Workflow automation with Power Automate • Databases, dashboards, forms, and approval systems • Process automation for teams currently relying on manual work Spreadsheet to Web App Development Many businesses start with Excel or Google Sheets because they are fast and flexible. But over time, those files can become hard to manage, slow, fragile, or difficult for multiple users to work with. I help businesses move from spreadsheet-based systems to web applications when they need: • Multiple users and permission levels • A cleaner interface for employees or managers • Centralized data instead of scattered files • Better reporting and dashboards • Automated approvals, emails, PDFs, or documents • Secure access from anywhere • A system that can grow with the business
