SYD X
About

I'm Tyemur. I build software people actually use.

Founder of SYD X, based in Péruwelz. I work across the whole stack (data, interface, mobile and AI) for non-profits and businesses in Wallonia and Brussels.

Most companies don't need more software. They need the right software: systems that fit how the team already works, keep data in one place, and take the repetitive work off people's desks.

That's what I build. Whether it's an internal tool, a customer-facing web app, a mobile app, a website, or an AI feature, I take it from idea to production. I handle the data model and APIs, the interface, and the AI layer on top.

Today SYD X is lead contractor on a custom ERP for a Walloon non-profit, and I designed and delivered its leave-management app.

02 How I build

AI-accelerated engineering.

AI speeds up the work; every line is reviewed and tested. I own the architecture, the review, the testing and the result. That's how one engineer can deliver across web, mobile, back end and AI.

Speed

Weeks, not months

AI agents handle the repetitive work, so prototypes arrive in days and full products ship much sooner.

Range

Any stack, any platform

I pick the technology that fits your project instead of forcing everything into the one stack I happen to know.

Quality

Human-reviewed, tested

Every change is reviewed, tested, and understood before it ships. AI speeds things up; it never replaces judgement.

Platforms I deliver on

Web apps iOS & Android Websites & CMS APIs & back ends Databases Cloud hosting

AI I build into products

LLM assistants RAG & search Document AI Agents Automation ML models
03 How I work

What you can expect.

Plain languageClear updates and honest estimates, without jargon.
Quality by defaultTested, secure, and documented code that's easy to hand over or extend.
Your data stays yoursGDPR-aware by design. You own the code and the data.
Measured, not hypedAI only where it beats the simpler option, with a clear metric to prove it.
Ship early, ship oftenYou see working software in weeks, not months.
Long-term partnerI stick around after launch to keep things running and growing.

Let's work together.

Whether it's a new product or an improvement to something you already have, I'd like to hear about it.
