BUILDER SHOWCASE
Explore real-world software, distributed databases, developer tools, and AI agents shipped by Catalyst Crew members during hackathons and open-source cohorts.
Web3 & SystemsHyperCache KV
Ultra-low latency in-memory distributed store written in Rust
Traditional centralized caching solutions introduce significant serialization overhead and thread lock contention under high-throughput write spikes.
Engineered a zero-copy binary network protocol over raw TCP with thread-pinned actor queues, reducing latency spikes by 74% compared to vanilla Redis.


AI & Machine LearningAgentPilot Dev
Autonomous CLI agent for local pull request testing & code refactoring
Developers lose hours diagnosing CI pipeline failures and writing repetitive test harnesses after every feature update.
Context-aware agent combining Tree-sitter AST parsing with lightweight local LLMs to generate high-confidence test suites and verify build passes locally.


Student ProjectsSynapse Mesh
P2P collaborative canvas for remote teams using WebRTC and CRDTs
Cloud-based collaboration tools suffer from high monthly SaaS subscription fees and latency lag for teams distributed globally.
Built a serverless canvas where state reconciles conflict-free on peer nodes, ensuring complete privacy, zero hosting costs, and instant local editing.


Hackathon BuildsZeroVote DAO
Private decentralized governance voting via zero-knowledge proofs
Public on-chain votes allow whale intimidation, vote buying, and front-running by malicious protocol participants.
Utilizes Circom zk-SNARK circuits to prove token voting weight within a private snapshot tree while keeping the voter identity masked.
Open SourceMicroLens Profiler
Lightweight CPU & memory flamegraph generator for Node.js microservices
Production debugging tools are often heavy, expensive, or require intrusive SDK code changes that affect production performance.
Runs as an external diagnostic agent utilizing Linux perf events and Chrome DevTools Protocol to monitor services with <0.8% CPU overhead.

AI & Machine LearningNeuroPulse
Edge speech-to-intent engine for hands-free terminal navigation
Developers with motor impairments or RSI struggle with repetitive keyboard shortcuts and commands during prolonged sessions.
Fine-tuned small language model running 100% locally on Apple Silicon and ONNX CPU backends with zero cloud audio telemetry.
