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 I work with companies that are using Excel, Google Sheets, macros, manual reports, or outdated workflows that no longer scale.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

I help teams turn complex technical systems into clear, structured content. My work includes technical articles, developer documentation, SaaS/product content, and tutorials that make APIs, identity systems, security topics, backend architectures, and other software challenges understandable to real-world users and developers. With a background in software engineering, I bring practical development experience to every writing, editing, and review project. I also leverage this background to perform detailed source code reviews and technical audits, combining a developer’s understanding of software systems with an editor’s eye for structure, clarity, consistency, and detail. I can also help teams design practical AI workflows for content operations, productivity, software development support, information organization, and lightweight automation. Such workflows improve real work without sacrificing accuracy or judgment. How I Can Help You... 💡 Clear, High-Impact Technical Writing and Developmental Editing ✔ Technical Articles / Tutorials / Explainers: I write clear, accurate articles on software development, security, or other technical topics so readers of any background actually understand them. ✔ Technical Documentation & API Guides: I create developer-friendly documentation, reference material, and API guides that help teams onboard faster and reduce support effort. ✔ Editing & Review: I can proofread your existing documents or content for clarity, consistency, and professional tone while maintaining technical accuracy. Technical editing, developmental editing, and copy editing as well. ✔ Process Documentation: I can document workflows, SOPs, and internal processes so that complex tasks become repeatable and easy to teach or train. ✔ Knowledge Base & SaaS Platform Support: I can build and maintain published content in knowledge base or SaaS environments, using tools such as Markdown, Git, and Confluence. ✔ Developer-Centered, Code-Forward Technical Content (what some call ‘dark mode’ writing): I can focus on real implementation details, architecture, SQL, APIs, and system behavior rather than high-level marketing language when required by the client. ✔ Lifestyle Articles / Product Roundups: I create informative and accessible lifestyle content and product roundups, for tech and other products. ✔ Graphic Design Support for Technical, Educational, and Marketing Assets: I can provide layout and light graphic design assistance for materials using Canva, InDesign, Photoshop, or Illustrator. 💡 Practical AI Workflows and Productivity ✔ AI Workflow Design: I can design practical AI-assisted workflows for content operations, research organization, documentation, task planning, and software-related knowledge work. Some preferred tools include ChatGPT, Claude, Gemini, AI coding assistants such as Claude Code, and automation platforms like Zapier. This list continues to evolve. ✔ Productivity and Lightweight Automation: I can help teams identify where AI tools and simple automation can reduce friction, make recurring work more repeatable, thus increasing productivity. ✔ Responsible Implementation: I focus on workflows that preserve accuracy, privacy, and human control — always with an emphasis on practical use rather than novelty. 💡 Structured Learning & Developer Training ✔ Educational Content & Courseware: I create tutorials, lessons, and learning materials for topics such as C#, OOP, mathematics, software development, and more. I also develop long-form projects — textbooks, self-study guides, and continuing-education courseware — ensuring technical accuracy and approachable learning. I work in Markdown/Git (docs-as-code) and can provide LaTeX layouts or short instructional videos when needed. 💡 Source Code Review & Software Engineering ✔ Code Review & Assessment Writing: I can review/audit your source code, then prepare artifacts, including code-review reports, mentoring notes, and best-practice recommendations that help developers improve structure and performance. Platforms include .NET, C#, C, C++, PHP, Node.js, Vue.js, Next.js, and others. ✔Software Engineering: .NET/C# development, specializing in REST APIs and utilities with a focus on performance optimization, security, and database design. Also proficient with C, C++, PHP, Node.js, Vue.js, Next.js, and others. 💡 Why Work With Me? ✅ Technical Depth: With many years in technical writing and software engineering, I understand the systems I document as well as the courseware I create. I ensure accuracy in every detail. ✅ Clarity, Engagement, & Usability: My writing and analysis emphasize readability and learning, helping both technical teams and non-technical stakeholders succeed. ✅ Trusted Experience: My track record spans decades of professional work, both on and off Upwork, with clients who value my ability to deliver clear, accurate, and dependable results. 📌 Let’s discuss how I can help with your project.
