Çağkan Aksun Yüksel

I help startups, scaleups, and enterprises build stronger technology foundations as a Fractional CTO, Technology Advisor, and Software Consultant.

Over the past 15+ years, I’ve led and supported teams across banking, fintech, and product development, blending strategy, architecture, and hands-on execution.

I focus on turning complexity into clarity, aligning technology with real business outcomes and helping organizations grow with structure, not chaos.

Outside of work, I’m an indie hacker, gamer, biker, parent, and lifelong learner.
Exploring, tinkering, trying and learning new things everyday for the joy of it.
