I will plan and build a custom ai web application for your business
Son Nguyen
About this gig
Have a business problem or app idea, but no complete technical specification?
You do not need perfect requirements. I help companies turn unclear needs into practical web applications that improve operations, reduce manual work, and support growth.
I combine business analysis, product planning, architecture, and hands-on development. Before coding, I help decide what to build now, what can wait, and what is not worth building.
With 15+ years building systems across industries, my experience ranges from departmental tools to ERP-scale applications and platforms serving thousands of internal and external users.
I can build:
- Internal business and productivity apps
- Workflow automation, dashboards, and portals
- AI-powered tools and SaaS MVPs
- Integrations and installable PWAs
My process:
- Understand the business, users, and workflow
- Define the right solution and first release
- Build, test, and deploy
- Document and hand over
AI is used where it creates real valuenot as a buzzword.
Please contact me before ordering Standard or Premium so we can confirm the scope, timeline, and outcome.

I help founders and businesses build, improve, and scale software and AI-powered products.
I’m a hands-on Fractional CTO and AI Product Builder with backgrounds in Computer Science, Quantitative Finance, software engineering, AI, and business.
I can help you turn an idea into a working product, build internal software and AI solutions for your company, automate business processes, or step into an existing application when the technical side has become difficult to manage.
My approach is simple: understand the business problem first, then build the right technology to solve it.

FAQ
Do I need complete technical requirements before contacting you?
No. Start with the business problem, current workflow, users and desired outcome. I will help define the right application, first-release scope and practical delivery plan.
Which package should I choose?
Choose Blueprint when you need clarity and a roadmap. Choose Prototype to test one core workflow. Choose First Release when the scope is understood and you are ready for a launchable application. Contact me before ordering Standard or Premium.
What do you need from me to begin?
Please share your business goal, intended users, current process, pain points, must-have features, examples and any systems that may need integration. Technical documents are helpful but not required.
Does my application need artificial intelligence?
No. I recommend AI only when it creates real value. Standard or Premium can include one agreed integration with an existing AI model or API. Model training, fine-tuning, advanced RAG and complex agents require a custom quote.
What kinds of applications can you build?
I build internal business tools, workflow systems, dashboards, customer or partner portals, productivity applications, SaaS MVPs, AI-assisted tools and installable Progressive Web Apps.
Can you integrate with our existing systems?
Yes, when those systems provide suitable APIs or other secure integration methods. I will review the required access, documentation, limitations and risks before confirming the scope.
Do you build native mobile or desktop applications?
This gig is for browser-based web applications and installable PWAs. Native iOS, Android, Windows or macOS applications are not included unless discussed and quoted separately.
Is deployment included?
Premium includes deployment to one agreed environment. Hosting, domains, AI usage, email, storage and other third-party service charges are paid directly by the buyer.
What do revisions and post-launch support cover?
Revisions cover adjustments within the agreed scope, not new features or major direction changes. Premium includes 14 days of support for defects against the approved scope. New functionality is quoted separately.
Will I receive the source code and own the application?
Standard and Premium include the custom source code created for the project after completion. Third-party libraries, APIs and services remain subject to their respective licenses and terms.
