Turning Digital Ideas
Into Reality

As an experienced software engineer, I built Onyxcode to help business owners and startups turn their digital ideas into reality without complex bureaucracy.

"Unlike rigid corporate agencies, here you collaborate directly with me from initial brainstorming straight into coding."

By blending expertise in Web & Mobile App Engineering with Creative Design (Logo, Brand Identity & UI/UX), I ensure every line of code written functions smoothly and matches visually stunning aesthetics.

Let's build your great digital product!

Frequently Asked Questions

Find quick answers to common questions about our services.

our Source Code, License, or Digital Assets are delivered 100% instantly! Once our payment gateway confirms your transaction as settled, the system will immediately generate the Download Link and attach your Serial License Key within the "Orders History" menu on your Client Dashboard.

Your transactions are highly secure, protected by bank-grade encryption via iPaymu. We accept almost all financial instruments in Indonesia, including instant QRIS scans, cross-bank Virtual Accounts (BCA, Mandiri, BNI, BRI), Credit Cards, and even convenience store payments.

I have a complex app or website idea. How do I order Custom Development services?

Absolutely! We strictly prioritize quality. We provide full repair warranty protection for any native defects (Error Logging) for the agreed timeframe from the date of purchase, provided you haven't critically modified the original core code blocks. You can utilize the "Support Ticket" button in your Client Dashboard to file a claim.

Because digital properties and assets can easily be duplicated endlessly after being downloaded, all Catalog Product sales are absolute (Final) and non-refundable (No Refund). Exceptions only apply to Custom Services based on the previously agreed written term phases before development begins.

No, that is strictly prohibited. All digital product purchases from our Catalog fall under a Single-Use Commercial License. This means you are completely free to use it for your own business or client projects endlessly, but you are strictly forbidden to repackage, distribute the raw files, or resell the core original source codes on any marketplace.

The base price of any Catalog product purchase does not include technical deployment to your Hosting (Self-Deploy). We always include an Instruction Manual (Documentation File) within every Download package. However, if you require our technicians to prepare your Server, Hosting, or Domain all the way to launch, simply reach out to us via Support Tickets, and we can assist for an additional Setup Fee.

Certainly! As full-stack software architects, you are fully entitled to request frameworks that align with your company's standardized architecture. Whether it operates on PHP foundations (CodeIgniter, Laravel), JavaScript ecosystems (React, Node.js), or mobile cross-platform technologies like Flutter. Voice these deep requirements upfront during our Live Chat session.

As long as you maintain access to the Account you utilized for the checkout, you have full enduring rights to re-download "Security Patch" versions down the line whenever the latest major iteration is released at absolute zero extra cost!
