FAQ
What types of web tools can you build?
I build small, custom browser-based tools, including business calculators, CSV tools, interactive dashboards, simple PDF generators, and HTML/CSS/JavaScript widgets. All tools are developed according to your requirements and must fit within the selected package’s scope.
Do I need hosting or special software to use my web tool?
No. Most tools work directly in a modern browser without hosting, installation, or internet access. You will receive the source code and usage instructions, preferably as one standalone HTML file. Some projects may require multiple files. Hosting and maintenance are not included.
What information do you need before starting?
Please provide a clear description of your tool, its required features, and any example files or design preferences. I will review your requirements to confirm the appropriate package and ensure the project fits within the agreed scope before development begins.
What is the difference between your packages?
Basic ($40) includes one simple feature. Standard ($80) includes up to three related features. Premium ($130) includes up to five related features. Each package covers one standalone web tool. Features must be clearly defined and reasonably simple.
Will I receive the source code?
Yes. You will receive the complete HTML, CSS, and JavaScript source code, along with basic instructions. Whenever practical, the tool will be delivered as a single HTML file. If multiple files are needed, they will be included in the delivery.
Are there any technical limitations?
Yes. My services focus on small, standalone browser-based tools. Backend development, external databases, user authentication, payment systems, complex API integrations, hosting, and ongoing maintenance are not included.
