React Advanced Patterns
Hooks Deep · Concurrency · Virtualization
Production React patterns. Compound components with context, render props vs. hooks, concurrent mode with useTransition, virtualization with react-window, and state machines with XState.
Cybersecurity
XSS · SQLi · JWT/OAuth · CSRF
Offensive and defensive security. XSS vectors, SQL injection prevention, JWT signing algorithms, OAuth 2.0 flows, CSRF tokens, CSP headers, and OWASP Top 10 deep dive.
Blockchain & Web3
Solidity · Smart Contracts · DeFi
Ethereum development. Solidity patterns (Ownable, ReentrancyGuard), ERC-20/721 tokens, Hardhat testing, DeFi primitives, and smart contract security auditing.
Mobile Engineering
React Native · Expo · Reanimated
Cross-platform mobile development with React Native & Expo. Shared navigation, Reanimated 3 gestures, Skia custom renders, offline-first with WatermelonDB, and app store deployment.
System Design
Kafka · Redis · Sharding · Rate Limiting
Distributed systems design. Event-driven with Kafka, caching strategies with Redis, database sharding patterns, rate limiting algorithms, CDN architecture, and CAP theorem trade-offs.
Rust & Systems Programming
WASM · Tokio · Ownership · Borrowing
Systems programming with Rust. Ownership model, lifetimes, async/await with Tokio, WebAssembly compilation, FFI with C, and building CLI tools with clap.

Trusted by developers
at every level
“OpenSyntax's Next.js course is the best free resource I've found. The 'use cache' and Server Actions lessons are production-grade. I got promoted months after completing the web track.”
Alex Chen
Full-Stack Engineer at Stripe
“The AI/ML Engineering path covers RAG, fine-tuning, and MLOps better than paid platforms I've tried. The quiz sections really test your understanding.”
Priya Sharma
ML Engineer at DeepMind
“I went from basic discord.py scripts to a sharded, production-ready bot serving 50k users. The PostgreSQL + Redis lessons were game-changing.”
Marcus Johnson
Discord Bot Developer
“The Cybersecurity course doesn't just teach theory — it shows you real exploit patterns and how to defend against them. OWASP Top 10 done right.”
Sarah Nakamura
Security Researcher
“Kubernetes, Terraform, and GitHub Actions all in one course? And it's free? This is what open-source education should look like.”
David Park
DevOps Lead at Cloudflare
“The Solidity security patterns section alone saved me from a reentrancy vulnerability in production. OpenSyntax teaches what matters for real-world Web3.”
