Mostly numerical correctness and performance work: premature overflow in Bessel functions, a flood fill that hung or leaked past its outline depending on the brush alpha, a socket timeout that was configured but never applied, generation settings an inference server accepted but never reported back, and a transposed convolution that silently computed only the first batch.

mantissa — a low-precision numerics core for neural networks, written in C.

It stores weights and activations in narrow formats (fp8, fp4, and a block-scaled variant) and runs dense and convolutional layers over them with hand-written NEON kernels. Every performance claim in the repository is backed by a paired randomised measurement against a same-binary control, and results that did not survive that test are documented as rejected rather than removed.

Software Engineer.

Before that, national-scale public-sector systems in .NET — both still in production:

• KYK, Turkey's student loans and housing agency — worked on a team that built 9 databases and 11 applications from scratch. Around 15 million users.
• Turkish Employment Agency (İŞKUR) — employment and public-benefit programme systems serving 8+ million users.

• Flight-controller firmware — modified the C sources running on a Pixhawk Cube autopilot.
