FAQ

Software developer questions

How much does a freelance software developer cost in Singapore? +

It depends entirely on the scope. A simple integration or automation tool might be S$800–S$2,000. A full custom web application with a database and admin panel is typically S$3,000–S$15,000+. I always provide a fixed quote with a clear scope before any work starts.

What kinds of software do you build? +

Primarily web-based applications — admin portals, customer-facing tools, internal dashboards, API integrations, and WordPress plugins. If it runs in a browser and needs custom logic, I can build it.

I have an idea but I'm not sure if it's technically possible — can you advise? +

Yes, absolutely. A free consultation is where I help you figure out what's feasible, what the right approach is, and what a realistic scope and budget looks like. No charge for the conversation.

Will I own the code you write? +

Yes, 100%. All code, all assets, all intellectual property is yours at the end of the project. I don't retain any rights or lock you into ongoing fees just to use your own software.

Can you take over a project from another developer? +

Yes. I regularly take on handover projects. I'll review the existing code, document what I find, and give you an honest assessment before we agree on a plan. No obligation.
