I will build and fix your mendix low code application
Zubair Mateen
About this gig
Mendix Advanced Certified developer with 8+ years of software engineering, currently delivering an enterprise finance platform for a client.
What I do:
- Microflow and nanoflow development, including complex approval and change-tracking workflows
- Domain model design that holds up as the application grows
- Java actions for logic Mendix can't express natively
- REST API integration and third-party connectors
- Custom SCSS styling, Data Grid 2 customization, RTL and multi-language support
- Large-scale data migration and batch processing
Why this matters: Most Mendix work on freelance platforms comes from people who learned the Studio Pro interface. I came to Mendix as a software engineer, which is why I can drop into Java when the microflow won't do it, write the SCSS when the theme won't cooperate, and design a domain model that doesn't need rebuilding in month six.
Certified: Mendix Advanced Developer, Intermediate Developer, and Rapid Developer.
Tell me what you're building or what's broken. I'll tell you what it takes including if it's not worth doing in Mendix.

FAQ
Which Mendix version do you work with?
Studio Pro 9.x and above. Tell me your version before ordering and I'll confirm compatibility.
Can you write Java actions, or only microflows?
Both. Java actions are where most low-code-only developers stop — I use them for batch processing, HashMap lookups, JSON diffing, and anything the microflow editor handles badly.
Can you fix an app someone else built?
Yes, that's a lot of my work. Send me a description of the problem or export access and I'll assess before you order.
Do you handle styling and theming?
Yes — custom SCSS, Data Grid 2 customization, empty-state handling, RTL layouts for Arabic. Mendix theming is genuinely fiddly and most developers avoid it.
Do you have Mendix certifications?
Advanced, Intermediate, and Rapid Developer. Happy to share verification.
Do you sign NDAs?
Yes. Send it over before you order.
