What I'm looking for

I’m looking for an enterprise AI/data transformation role where I can lead teams, modernize platforms, and deliver measurable outcomes with C-level partners—turning complex technical plans into scalable business growth.

I’m a technology leader with 10+ years’ experience in enterprise environments, currently Head of Technology & Development at Datanext Group (2022-2025). I lead AI, backend, and data teams (10-15 FTE each) for enterprise clients, shaping IT, platform, and AI strategy with C-level stakeholders.

I’ve delivered measurable business impact, including 100% revenue uplift and a 40% cost reduction in 2 years through modernization programs like cloud migrations and microservices. I’m known as the link between executive mentality and relentless execution—translating complex technical challenges into clear business terms while aligning vision with scalable outcomes.

Earlier, I built and scaled data science and engineering capabilities, including leading Azure/AWS migration programs and redesigning legacy data platforms. I introduced standardized agile delivery models that reduced lead time by 30%, and I actively coach engineers while contributing to strategy, growth, and product roadmap discussions.
