Client Success Stories

See how we've helped leading companies achieve their product goals.

Prismatic Stack came in with the goal of transforming Product at Yoke. Alexander was onboarded quickly and his tenacity was infectious, energising all those around him. No task was too big, no project was too scary. He broke things down and helped us raise the bar.

Mustafa Mohamed, CTO - Yoke Network

Alexander's diligence and hard-work will take him incredibly far. Picfair is modernised and we're now confident about our store product's defensibility. I've learned a lot from him and I'm sure he'll continue to do great things.

Benji Lanyado, CEO - Picfair

Alexander has a good technical understanding of complex workflows, processes and can translate business needs into representative technical product design & technology. He has excellent client facing communication skills, online advertising- and technical understanding that helped us address & mitigate problems during the development & launch of ugc.today.

My Story

My journey began with a fascination for how people and organisations adapt in complex systems, which led me to study philosophy, politics, and economics. But I craved real-world impact - so I've since immersed myself in every stage of the business lifecycle: from global enterprises to high-growth scale-ups, early-stage start-ups, and now, cutting-edge AI projects.

I thrive in high-ambiguity environments where rapid learning, process design, and relentless execution are essential. My approach is hands-on and data-driven: I turn ideas into shipped products, guide cross-functional teams, and drive measurable results - cutting costs, compressing cycle times, and raising NPS through experimentation and automation.

My strengths lie in AI systems, growth loops, internal tools, and web applications. As an eternal optimist and a process-oriented builder, I help organisations unlock their next level of performance, especially when the path forward is unclear.
