Senior🎓
Top SchoolSergiy Shelkovnikov is a founder and GIS-focused software engineer with over 11 years building precision farming and geospatial platforms from Ukraine. He created ShelS Company in 2008 to deliver GIS solutions, launched the collaborative mapping service GISFile in 2014, and evolved that work into PreAgri — an online system (since 2016) that integrates drone/satellite imagery and field equipment telemetry for actionable precision-agriculture insights. His products emphasize interoperability (REST APIs, server integrations) and have demonstrable on-farm impact, reducing inputs and resources by up to 42% while improving yields. Combining deep GIS, server-side engineering, and agricultural domain experience, he specializes in adapting spatial systems to customer workflows and legacy equipment. An unusual strength is translating community-driven mapping features into enterprise-grade precision farming services that scale from single holdings to integrated agribusiness deployments.
