Secure Messaging

(Signal-style E2EE)

A modular Python system demonstrating modern end-to-end encrypted chat over an untrusted relay. Uses X3DHE for key exchange, HKDF for derivation, AES-GCM for AEAD, and a per-message ratchet to provide confidentiality, integrity, authenticity, and forward secrecy.

Dual Illumination Exposure Correction

An automated imaging pipeline that estimates scene illumination and corrects under/over-exposed images, by integrating multi-exposure fusion for natural results.

Measured gains: +4.4 PSNR and +0.13 SSIM with ~1.5s per image runtime.

Cloudflare Edge Compute

A CloudFlare-driven edge-compute exploration packaged and documenting patterns for routing, caching, and deploy-from-scratch at the network edge. Ideal as a starter template and notes for fast global responses.

STaR Bootstrapping — Reasoning on GSM8K

End-to-end pipeline that fine-tunes a small instruction model with STaR: zero-shot CoT → supervised fine-tuning → answer-conditioned rationale regeneration.

​

Result: exact-match accuracy rose:

38.27% (zero-shot) to 52.54% with STaR

(+14.27 points; +10.84 over vanilla SFT).
