Zauad Shahreer A.

I build custom R Shiny dashboards, AI-assisted data tools, and web applications that help teams explore data, automate reporting, and make better decisions. With 60+ completed Upwork projects, 1,100+ hours, 100% Job Success, and Top Rated status, I specialize in turning complex data, Excel files, research workflows, and business processes into clean, interactive tools that are easy to use and maintain. I can help with: • Custom R Shiny dashboards and web apps • AI-assisted dashboards, chatbots, and data exploration tools • OpenAI/API integration inside Shiny apps • Interactive charts, tables, maps, and filters • Clean UI using CSS, JavaScript, HTML, bslib, and shinydashboard • R Markdown, Quarto, and automated reports • Data cleaning, transformation, and visualization • Database-connected Shiny apps • Debugging, refactoring, and improving existing Shiny apps • Deployment support and app maintenance Clients usually work with me when they need more than a basic dashboard. I can help plan the app structure, build the reactive logic, improve the UI, clean the data workflow, add useful AI features, and make the final app easier for users to understand. I have worked on Shiny apps for business dashboards, research tools, scheduling systems, economic models, flow cytometry data, maps, CRUD apps, AI-assisted tools, and data visualization platforms. I was also a Shiny Contest finalist, which reflects my focus on building useful, polished, and well-designed Shiny applications. Please note: I do not take academic assignments, exams, or homework projects. If you need a reliable R/Shiny developer for a dashboard, data app, AI-assisted workflow, or reporting tool, I would be happy to help.
