Background

I build software companies and products at the intersection of environmental expertise, data, and artificial intelligence. My focus is on turning complex, regulation-driven domains into scalable, reliable digital platforms that create real operational value.

I take end-to-end ownership—from product vision and business modeling to architecture, implementation, and long-term operation. I work hands-on with modern cloud stacks, data platforms, and AI-driven systems, using machine learning and automation to improve data quality, transparency, and decision-making rather than adding complexity for its own sake.

What distinguishes my work is the combination of domain depth and technical execution. I design systems that can evolve: modular, auditable, and ready for production use in critical environments. AI is an integral part of this approach—used pragmatically to accelerate workflows, enhance analytics, and enable new product capabilities.

I thrive in environments where technology, business, and responsibility meet, and where building something sustainable matters more than shipping the next demo.
