Code / Engineering
This is the implementation record: independent code and test fixtures, production engineering case studies, and published security evidence. I keep those categories separate so it is clear what I built, what I verified locally and what remains private. There are also mobile apps, audio projects and small tools I made because they were interesting.
Mobile, backend and security work from enterprise environments. Architectural decisions and failure paths, not private customer artifacts.
Read the case studies →Runnable Rust, Go and backend implementations, with source downloads, attack reproduction, local evidence and limitations.
Inspect Rust and Go →Documented authorization failures, reproducible local tests, and defensive analysis.
Security write-ups →Start with evidence
Checked ELF parsing, 6 tests and 10,000 mutation cases. Inspect the source and the hardening claims it deliberately cannot make.
Code, tests and limits →A local 24-request replay attack: 120 units applied by the vulnerable handler, 5 by the fixed one.
Reproduce the exploit and fix →A policy reference and separate local Go runtime with explicit delegation, tenancy, egress and replay boundaries.

I trained a small audio-activity classifier with NumPy, built clean and noisy held-out sets, and ran controlled feature and augmentation ablations using repeatable seeds and explicit precision/recall/F1 results.
Audio · Python
I built backend verification safeguards so retries and dependency outages would not quietly bypass risk and authorization checks.
Backend
I implemented a voice-to-CRM event service with HMAC-verified webhooks, replay-window checks, tenant-scoped idempotency, duplicate detection and recovery after simulated downstream outages.
Backend
I hardened iOS device-trust decisions by separating untrusted client signals from evidence verified by backend services.
iOS · Backend · Swift
I implemented and trained a small nonlinear vector-quantized audio autoencoder with a learned encoder, decoder and discrete codebook, then compared measured reconstruction error to an 8-bit companding baseline.
Audio · Python
I worked on session-recovery controls that made identity checks, step-up decisions and failure states explicit instead of weakening authentication during recovery.

No public original projects to show right now. The private stuff is staying private.
I like hearing about small tools, surprising bugs and things people build for fun. If something here sparks an idea, send it my way.
