HyperCache KV

Ultra-low latency in-memory distributed store written in Rust

Problem:

Traditional centralized caching solutions introduce significant serialization overhead and thread lock contention under high-throughput write spikes.

Solution:

Engineered a zero-copy binary network protocol over raw TCP with thread-pinned actor queues, reducing latency spikes by 74% compared to vanilla Redis.

Autonomous CLI agent for local pull request testing & code refactoring

Problem:

Developers lose hours diagnosing CI pipeline failures and writing repetitive test harnesses after every feature update.

Solution:

Context-aware agent combining Tree-sitter AST parsing with lightweight local LLMs to generate high-confidence test suites and verify build passes locally.

Synapse Mesh

P2P collaborative canvas for remote teams using WebRTC and CRDTs

Problem:

Cloud-based collaboration tools suffer from high monthly SaaS subscription fees and latency lag for teams distributed globally.

Solution:

Built a serverless canvas where state reconciles conflict-free on peer nodes, ensuring complete privacy, zero hosting costs, and instant local editing.

ZeroVote DAO

Private decentralized governance voting via zero-knowledge proofs

Problem:

Public on-chain votes allow whale intimidation, vote buying, and front-running by malicious protocol participants.

Solution:

Utilizes Circom zk-SNARK circuits to prove token voting weight within a private snapshot tree while keeping the voter identity masked.

MicroLens Profiler

Lightweight CPU & memory flamegraph generator for Node.js microservices

Problem:

Production debugging tools are often heavy, expensive, or require intrusive SDK code changes that affect production performance.

Solution:

Runs as an external diagnostic agent utilizing Linux perf events and Chrome DevTools Protocol to monitor services with <0.8% CPU overhead.

Edge speech-to-intent engine for hands-free terminal navigation

Problem:

Developers with motor impairments or RSI struggle with repetitive keyboard shortcuts and commands during prolonged sessions.

Solution:

Fine-tuned small language model running 100% locally on Apple Silicon and ONNX CPU backends with zero cloud audio telemetry.
