Custom Single-Purpose Web AppsAli Shan
I build high-impact, single-purpose web applications designed to solve one problem perfectly. Whether you need a lead-generation calculator, an interactive tool, or a custom internal utility, I deliver polished, fast, and fully functional micro-apps that engage users immediately.
This service is perfect for founders, marketers, and creators who need a specific feature built without the bloat of a full product development cycle.
Tech Stack: Built with modern, scalable tech (React, Next.js, Tailwind CSS) ensuring your tool is fast and future-proof.
Use Cases: Ideal for "Engineering as Marketing" tools (ROI calculators, quizzes), internal business utilities, or MVP features to test a market.
Speed: Focused scope means faster turnaround—typically delivered in days, not weeks.
What's included
Fully Deployed Web Application
A live, production-ready URL where your micro-app is hosted and running smoothly (deployed via Vercel, Netlify, or your preferred hosting provider). The app will be optimized for performance and load speed.
Complete Source Code Repository
Full ownership of the clean, organized, and well-commented codebase (delivered via GitHub or zip file). The code is built using modern standards (React/Next.js/Tailwind), making it easy for future developers to maintain or scale.
Responsive & Adaptive UI Design
A polished user interface that looks perfect on all devices—from desktop monitors to mobile phones. The design will adhere to accessibility standards and match your provided brand guidelines (colors, fonts, and logos).
Integration & Embed Support
If you plan to host this micro-app on a subdomain or within an existing site (like Webflow or WordPress), I will provide the necessary embed codes (iFrames) or DNS configuration instructions to ensure seamless integration.
Handover Documentation
A concise "Read Me" document explaining how the app works technically. This includes instructions on how to update basic text/content, manage API keys, and handle any third-party integrations used in the build.
FAQs
Yes! I can build the app as a standalone page (e.g., tool.yoursite.com) or provide you with an iframe code to embed it directly into Webflow, WordPress, or Framer.
For most micro-apps, we can use free tiers on robust platforms like Vercel or Netlify. If your app requires a database or heavy traffic, I will advise you on the low-cost options available
I write clean, documented code. I will show you exactly where the "logic" lives so a future developer (or I) can easily tweak the math without breaking the design.
I can do both. If you have a Figma file, I will match it pixel-perfect. If not, I can design a clean, modern interface based on your existing brand guidelines.
