About the service

I develop production software in Nim — a statically-typed compiled language with Python-like syntax. My specialty is turning slow or brittle scripts into fast self-contained binaries that just run. If you have a tool in Python or Bash that's eating CPU and memory, I'll rewrite it in Nim and hand you an executable with no runtime dependencies. Typical tasks include console utilities with argument parsing, subcommands, colored output and shell completion; HTTP and TCP backends that fit in a millisecond per request; log and data pipelines pumping gigabytes without hiccups. I leverage Nim's strengths: interop with C without overhead to wrap existing C or C++ libraries and deliver a clean interface, and a macro system for compile-time code generation that eliminates boilerplate rather than creating it. I take correctness seriously: setting up unit tests, reproducible builds and cross-compilation for Linux, macOS and Windows from one machine. The delivery includes documented source, a reproducible build script and compiled binaries for your platform. Over recent years I've shipped parsers, network daemons, bridges between Nim and native SDKs, and async services on async await. Describe the task, input format and required throughput — I'll send a small prototype before the main work starts.
