I help teams build, evolve, and operate reliable, revenue-critical SaaS and data-intensive platforms.
My work focuses on long-lived systems that are easy to maintain, adapt, and scale over time — especially in environments where data quality, performance, and reliability matter.
I value pragmatic engineering, clear communication, and systems that deliver what they promise — in production.
Design, operation, and long-term stewardship of large-scale scientific and geoscience databases, including complex geochemical and analytical datasets.
Full-stack development of production web applications, with strong focus on Ruby on Rails, APIs, subscriptions, and data-driven product features.
Improving reliability, performance, and maintainability of existing systems, reducing operational friction and long-term cost.
