About me

Maciej Tyra developer,
builder, strategist

I am a full-stack developer and Process Automation Engineer at SynthIT, specializing in designing and implementing custom systems that serve as the digital heart of businesses. Previously, I was the Co-Founder & CTO of Digitay.pl (which I successfully exited in May 2026 on excellent terms after selling my shares), where I drove technical strategy and managed over 50 client accounts.

I work at the intersection of technology, performance, UX, and business goals. My approach combines clean engineering with product thinking. I create solutions that don't just look good, but deliver measurable results.

From architecture to deployment, from frontend polish to analytics implementation. I cover the full spectrum of modern web development with a focus on speed, scalability, and business impact.
