About Stirex - Custom apps, AI automation, and long-term support — founder-led.
We help individuals and small businesses turn ideas into reliable software and AI-integrated systems.
Stirex designs, builds, and supports custom apps, automations, and AI integrations—from first idea to long after launch.
If you're struggling with…
- You've been burned by developers who disappeared after launch
- You have an idea but don't know what to build first
- Manual processes are eating your time and money
- Your business is growing but your tools aren't keeping up
- You want AI, but don't want hype or risky experiments
- You need someone who can own the whole project, not just write code
…then we should talk.
Our Process - How we work
We're not a feature factory. We're here to solve problems and stick around after launch.
Clarify the problem
We dig into what you actually need—not just features, but outcomes.
Design a practical solution
We scope what makes sense for your budget and timeline—and what we won't build.
Build incrementally
You see progress early and often. We adjust based on real feedback.
Launch and monitor
We don't just ship and disappear. We make sure it actually works in the real world.
Stay available
Long-term support is part of the deal. Your project doesn't become an orphan.

About the Founder
I started Stirex because too many businesses get stuck between agencies that over-promise and freelancers who disappear. After nine years building mission-critical systems for global banks, I wanted to offer something different: direct access to senior expertise, honest advice, and someone who stays accountable long after launch.
When projects need more hands, I bring in people I've worked with and trust. When they don't, you get my full focus. Either way, you always know who's responsible for the outcome.
Why Stirex
At Stirex, things move fast. Fewer layers, faster decisions, and direct access to the person responsible for the outcome. I lead every project, and bring in trusted specialists when needed.
- Founder-led delivery. No account managers. No game of telephone. You work directly with the person building your product.
- Flexible when needed. Complex project? We bring in trusted specialists. Simple app? You get focused, lean delivery.
- AI without the hype. We use AI where it actually helps—not to check a buzzword box. If it doesn't solve your problem, we'll tell you.
- Long-term mindset. We build relationships, not just projects. Your success months after launch matters to us.
- Battle-tested foundations. Nine years building systems for global banks means we know how to build things that last—and things that scale.
- Faster starts. We've already built internal tools and patterns. That means less reinventing the wheel and faster time to your first working version.
