Where things live

This site and Oravont

This site is the scholarly record: papers with full-text PDFs, technical notes and the career record. Practice work, capability statements and formal proposals sit with Oravont Systems LLP, the defence R&D practice I founded in Noida in 2024. Its site, oravontsystems.com, also describes the engineering software tools (SSR‑Sim, Dhvanyakalan, ABNContour, SMS‑Suite, available to defence organisations, shipyards and research institutions on enquiry) and the open DEMON‑Analysis toolkit. Everything published on either site stays at an unclassified level.
