Implemented a complete JPEG encoder and decoder in Python directly from the ITU-T T.81 specification — no image libraries, no reference implementation. Includes:
- Colour space conversion (RGB → YCrCb)
- Block DCT, quantization tables, zig-zag ordering
- Run-length encoding + Huffman entropy coding
- LZW compressor
- Quality metrics: PSNR, SSIM, MSE, MAE
- Validated against libjpeg across 40 test images
- 🔐 SOC operations — incident triage, detection rules (KQL), automated response playbooks
- 🔬 PhD applications — systems security, program analysis, formal verification (2027 start)
- 📚 Keeping sharp with Python systems engineering and security automation
