I built ProofFace a visual provenance & content verification engine in Rust
I have been building ProofFace an end-to-end visual provenance and content verification engine built in Rust.
The idea is simple:
Finding an image online doesn’t prove that it’s authentic, original, or unchanged.
So I built a verification pipeline that goes from:
📸 Image input
→ 🧠 Neural face detection
→ 🔎 Web visual discovery
→ 🧬 Biometric similarity
→ 🔐 Deterministic SHA-256 fingerprinting
→ ⛓️ Polygon Amoy blockchain proof
→ ✅ Verification result
Some of the things I worked on:
• ONNX-based face detection
• 128-dimensional biometric embeddings
• Presentation attack detection
• Parallel visual candidate evaluation
• Cosine similarity matching
• RFC 8785 JSON canonicalization
• SHA-256 content fingerprinting
• Polygon smart-contract integration
• Automated unit & integration testing
The project currently has 30 passing tests.
What I enjoyed most was bringing several different areas together computer vision, Rust systems programming, cryptography, and blockchain into one reproducible verification workflow.
Would love to hear what you’d improve or add to a system like this.

What happens when you stop chasing the market and start watching it?
For Oracle Perps, the answer was a visual identity built around precision, transparency, and signal over noise.
Oracle Perps is a market intelligence platform that tracks the positioning of leading perp wallets across Hyperliquid, Phoenix, and GMX — turning real-money activity into sentiment, live market intelligence, and graded predictions.
The challenge was to create a brand that could feel institutional and trustworthy without becoming cold or predictable. The identity needed to communicate observation, intelligence, and quiet confidence while standing apart from the visual clichés of crypto and trading.
The result is a dark-first visual system built around a precise geometric mark, a refined wordmark, and a restrained visual language designed to make complex market signals feel clear and intentional.
A quiet identity for a platform built to see what others miss.

Cool designing and purposeful building. Great work!
A look back at a crypto wallet concept from our archives. We designed the core screens, balance, statistics, and swap flow, using an electric blue and neon yellow palette paired with Gilroy for a bold fintech feel.
The set covers balance overviews, portfolio breakdown, auto save settings, and a swap screen, all built around one consistent visual identity.
A concept that still holds up: clean, punchy, and easy to navigate.
