Hi, I’m Daniel Prosianikov - a fractional CTO and Solution Architect with roots in Kyiv, Ukraine, now based in Barcelona. For nearly two decades, I’ve been immersed in technology — from writing my first lines of code as a kid to building production-grade systems for startups and scale-ups worldwide.

A path shaped by curiosity

My journey began at 12, when a teacher at my math lyceum introduced us to Logo - a simple programming language that let us draw shapes using commands, loops, and angles. I was instantly fascinated. Soon after, I picked up BASIC and Pascal, and built my first game: a DOS pixel arkanoid. It felt like creating something magical from scratch.

By the time I was still in lyceum, I was experimenting with HTML, JavaScript, and WordPress - even landing freelance jobs. One of the most formative projects was a knowledge assessment system I developed for my school. Seeing my classmates actually use something I built sparked a deep sense of purpose. Code wasn’t just a toy - it could be real, useful, and impactful.

Building systems from the ground up

I pursued my passion further at Ukraine’s top technical university, where I studied software for automation and control systems. This gave me a deeper understanding of how complex, interconnected systems work - both in theory and in practice. My academic work and hands-on projects evolved side by side, reinforcing each other and shaping the way I approach technology to this day.

Since then, I’ve worked across startups, R&D departments, and product teams, helping to bring innovative ideas to life. My experience spans multiple industries, including:

• IoT and industrial automation

• AI and computer vision

• Healthcare and wellness tech

• Smart energy systems

What I Believe

Through all these years, one thing has remained constant:

Technology is just a tool - what matters is solving the right problem.

That belief drives the way I build. I always aim to think beyond implementation and ask:

• Why are we building this?

• Who will use it, and how?

• How would I feel using it, if I were them?

That mindset is what I bring to every collaboration - whether I’m leading as a fractional CTO, designing system architecture, or helping a team take their idea from messy sketch to working product.
