About the service
I write production systems code in ATS (Applied Type System) — a language that lets you combine the speed of bare metal with mathematically verified correctness. If you need a driver, embedded routine, parser, or hot path that has no right to leak memory or read past a buffer, I will encode those guarantees directly in the type system. In ATS the compiler forces me to discharge proof obligations before code even compiles, so a whole class of errors that slip into C releases unnoticed simply does not compile here. Work starts with your invariants. We agree on what must hold: no double-frees, no buffer overruns, linear ownership of every resource, guaranteed termination of recursive routines. Then I express this in dependent types and linear proofs, implement code against them, and deliver a result that carries its own safety certificate. Since ATS compiles to clean C, the result integrates into your build without issue and runs without garbage collection overhead. Delivery includes ATS sources, generated C, build script, a small test harness with proof annotations, and a text note explaining each proven invariant. Over years of low-level work I have built lock-free structures and safe ATS bindings to legacy C libraries. Reasoning about pointers, sizes, and lifetimes at the level of formal logic is routine for me. Describe a constraint that worries you, and I will turn it into a theorem the compiler checks at every rebuild.
