About

To date, I've had the privilege of working on challenging projects with Revolut, The Coca-Cola Company, Novartis, Heineken, Macy's, American Bankers Association, Polo Ralph Lauren, Bloomingdales, Hudson Bay Company (Saks 5th Avenue, Saks Off 5th), Boots, Homebase, Ferrero Rocher, Statoil, Dixons Carphone, T-Mobile, Absolut Vodka, Adidas, Porsche, Ermenegildo Zegna, Disney Pictures and more.

Over the past 20 years my portfolio includes successful delivery of projects for a diverse range of clients, from medium businesses to global enterprises. My technical journey encompasses large-scale systems refactoring, modularisation, data analysis and BI platforms, data integration tools, data stream analytics, and the creation of advanced ML/AI applications. In these ventures, I've had roles ranging from an engineer to a solution architect and leadership roles.

I advocate for nurturing organisational culture and have a keen interest in DDD, Event Storming, software architecture at scale, Big Data, and the applied ML/AI.

According to Gallup, my top 5 strengths are Achiever, Relator, Arranger, Strategic, Learner. I'm driven by goals, fuelled by continuous learning, and take pride in leading teams to break new grounds. I naturally like to dig into a given domain while aiming to craft solutions elegantly simplistic yet technologically advanced.

# Product & R&D Leadership as CTO
Throughout my career, I was often responsible for assessing product goals, strategy, leading interdisciplinary teams, and driving bottom-up innovation. I've led several R&D initiatives, fostering partnerships with the academic world. Notably, I've co-authored R&D grant projects amassing a budget of over $6M, targeting innovations such as ML/AI-driven hiring processes and combating abuse in high-volume data streams.

# Solutions consulting
I'm a certified facilitator experienced in managing and consulting. I've led strategic initiatives, worked closely with senior management. I've overseen multi-million dollar projects from inception, vendor selection, negotiation, to delivery.
