Core Components:

• Frontend Architecture: React, Vue, Angular with TypeScript
• State Management: Redux, Context API, VueX
• Build Tools: Webpack, Vite, Babel
• Progressive Web Apps (PWAs) implementation

Best Practices:

Modern web development emphasizes component-driven architecture with micro-frontends. Using WebAssembly for performance-critical tasks and implementing Server-Side Rendering (SSR) for SEO optimization. Real-time features through WebSockets and GraphQL subscriptions.

Case Study:

Built an e-commerce platform handling 10k+ concurrent users using Next.js with incremental static regeneration, achieving 95% Lighthouse performance score.

Key Architecture Patterns:

• Microservices vs Monolith: When to use which
• Event-Driven Architecture with Kafka/RabbitMQ
• Containerization with Docker and Kubernetes
• Serverless Functions (AWS Lambda, Cloud Functions)

Security Essentials:

Implementing OAuth2.0/JWT authentication, rate limiting, and SQL injection prevention. Using Hashicorp Vault for secrets management and OpenTelemetry for distributed tracing.

Performance Optimization:

Caching strategies with Redis, database connection pooling, and query optimization. Case study: Reduced API response times from 2s to 200ms for a fintech application.

Technology Stack:

• Flutter with Dart: Google's UI toolkit
• React Native: JavaScript ecosystem
• Kotlin Multiplatform: Native shared logic

Key Considerations:

Implementing platform-specific UI/UX patterns, handling native modules, and optimizing for various screen densities. Using Firebase for real-time sync and offline-first strategies.

Performance Metrics:

Achieving 60fps animations, reducing APK/IPA sizes through ProGuard/R8 optimization, and implementing background sync with WorkManager.

Core Principles:

• CAP Theorem: Consistency vs Availability
• Load Balancing Strategies: Round Robin vs Least Connections
• Database Sharding Techniques
• Circuit Breaker Pattern for fault tolerance

Cloud-Native Design:

Implementing auto-scaling groups, cloud storage solutions (S3, Blob Storage), and CDN configurations. Case study: Designed a video streaming platform handling 1M+ concurrent streams.

Monitoring & Alerting:

Implementing Prometheus/Grafana dashboards, setting up SLA/SLO monitoring, and using PagerDuty for incident management.

Integration Patterns:

• RESTful API Design: Richardson Maturity Model
• GraphQL: Schema stitching and federation
• gRPC: High-performance RPC framework
• Webhooks: Event-driven integrations

Security Protocols:

Implementing OAuth2.0 flows, mutual TLS authentication, and rate limiting. Using API gateways (Kong, Apigee) for traffic management and analytics.

Versioning Strategy:

Semantic versioning, backward compatibility, and deprecation policies. Case study: Migrated a monolith API to microservices with zero downtime.

Database Types:

• Relational: PostgreSQL, MySQL
• Document: MongoDB, Couchbase
• Graph: Neo4j, Amazon Neptune
• Time-Series: InfluxDB, TimescaleDB

Optimization Techniques:

Query execution plans analysis, index optimization strategies, and connection pooling. Implementing read replicas for scaling read-heavy workloads.

Disaster Recovery:

WAL archiving, point-in-time recovery, and multi-region replication. Case study: Achieved 99.999% availability for a healthcare database system.

Key Concepts:

• Qubits vs Classical Bits: Superposition & Entanglement
• Quantum Gates: Hadamard, CNOT, Toffoli
• Shor's Algorithm for prime factorization

Development Tools:

Working with IBM Qiskit, Microsoft Quantum Development Kit, and D-Wave Leap. Case study: Optimized logistics routing using quantum annealing, reducing computation time from hours to seconds.

Core Components:

• Entity Component System (ECS) pattern
• Physics Engine Integration (Havok, PhysX)
• Procedural Content Generation

Optimization Techniques:

Implementing occlusion culling, LOD systems, and GPU instancing. Case study: Achieved 120 FPS on mobile devices using custom shader optimization.

Toolchain:

• Infrastructure as Code: Terraform & Pulumi
• Monitoring: Prometheus & Grafana Loki
• Security: Trivy & Falco

Best Practices:

Implementing blue/green deployments, canary releases, and chaos engineering. Case study: Reduced deployment failures by 80% using automated rollback strategies.

Ethereum Ecosystem:

• Smart Contract Development Lifecycle
• ERC Standards: ERC-20, ERC-721
• Layer 2 Solutions: Polygon, Optimism

Security Considerations:

Preventing reentrancy attacks, integer overflow vulnerabilities, and proper use of Oracles. Case study: Built a DeFi protocol handling $1M+ TVL with formal verification.
