Zig Systems Engineer: Embedded, Wasm, C Interop

I build systems software in Zig, and I treat every byte and every cycle as something I have to justify. Manual memory control is the core of how I work: I pass explicit allocators, choose arena or fixed-buffer strategies where they fit, and use Zig's testing allocator to prove there are no leaks or double frees before I ship. If you already have a C or C++ codebase, I plug Zig into it directly. Because Zig imports C headers with almost no friction, I can wrap an existing library, replace one hot module, or use `zig cc` as a drop-in cross-compiler for your whole project. Cross-compilation is where Zig quietly shines, and I lean on it hard: from a single machine I produce binaries for Linux, macOS, Windows, ARM boards and bare-metal targets without dragging along a fragile toolchain per platform. On the embedded side I write firmware for microcontrollers with tight RAM budgets, no heap when the target forbids it, and predictable interrupt paths. For the web I compile Zig to WebAssembly to move heavy number-crunching, parsers and codecs off JavaScript and into something small and fast. Comptime is my favourite tool: I generate lookup tables, specialise data structures and validate configuration at compile time so the runtime stays honest and the binary stays small. Typical deliverables include the source, a `build.zig` that just works, unit tests, benchmarks, and a short note on the memory and safety decisions I made. I have shipped parsers, allocators, protocol codecs and MCU firmware, and I care as much about the handoff as the code. Tell me your target and your constraints, and I will tell you honestly what Zig buys you.
