☁️Cloud & DevOpsEvent-Driven Microservices: Kafka Patterns, Saga Orchestration
Build event-driven microservices that work in production: design Kafka topic schemas with Avro, implement the saga pattern for distributed transactions, enforce idempotency to handle duplicate events, and handle consumer group rebalancing without data loss.
🌐Web DevelopmentNext.js Middleware Patterns: Auth, Redirects, A/B Testing
Master Next.js Edge Middleware: implement authentication guards without full server roundtrips, configure redirect rules, run A/B tests at the edge with cookie-based assignment, and geo-route users to regional content — all with sub-millisecond latency.
🚀SaaS & StartupsSaaS Trial Conversion: Trial Design, Upgrade Prompts, Email Sequences
Maximize SaaS trial-to-paid conversion: design time-limited vs usage-limited trials, build contextual upgrade prompts tied to activation events, implement automated email sequences with behavioral triggers, and engineer activation gates that convert without frustrating users.
🌐Web DevelopmentPrisma in Production: Schema Design, Migrations, Connection Management
Run Prisma in production correctly: design schemas that avoid N+1 queries, manage migrations safely with shadow databases, configure connection pooling for serverless environments, and optimize slow queries with query events and Prisma's explain.
🌐Web DevelopmentWebSocket Authentication: Token-Based Auth, Reconnection
Implement production WebSocket authentication: validate JWT tokens during handshake, handle token refresh during long-lived connections, implement automatic reconnection with exponential backoff, and choose between connection-level and message-level authorization.
☁️Cloud & DevOpsAWS ECS Fargate in Production: Task Definitions, Service Discovery
Run production workloads on AWS ECS Fargate: configure task definitions with Secrets Manager, set up service discovery with Cloud Map, implement blue/green deployments with CodeDeploy, and monitor with Container Insights.
🌐Web DevelopmentReact Hook Form + Zod: Complex Validation, File Uploads
Master React Hook Form with Zod validation: build complex nested forms, validate file uploads with type and size constraints, implement multi-step wizard forms with shared state, and handle async server-side validation without compromising UX.
🚀SaaS & StartupsSaaS Self-Serve Billing Portal: Plan Management, Invoices
Build a self-serve SaaS billing portal: integrate Stripe Customer Portal for plan changes and payment updates, implement custom plan upgrade flows, display invoice history, and handle proration calculations for mid-cycle plan changes.
☁️Cloud & DevOpsOpenTelemetry for Node.js: Auto-Instrumentation, Custom Spans
Instrument Node.js applications with OpenTelemetry: set up auto-instrumentation for HTTP, Express, and database calls, create custom spans for business logic, export traces via OTLP to Grafana Tempo or Jaeger, and correlate traces with logs and metrics.
☁️Cloud & DevOpsKubernetes StatefulSets: PVCs, Headless Services, Ordered Scaling
Deploy stateful workloads on Kubernetes: configure StatefulSets with PersistentVolumeClaims, expose pods via headless services for stable DNS, manage ordered pod lifecycle for databases and message queues, and understand when to use StatefulSet vs Deployment.
🌐Web DevelopmentMonorepo Release Management: Changesets, Semantic Versioning
Manage releases in a monorepo: implement Changesets for versioning and changelogs, configure automated publish pipelines with GitHub Actions, handle peer dependency bumps, publish to npm with provenance, and coordinate breaking changes across packages.
🚀SaaS & StartupsSaaS GDPR Engineering: Data Deletion, Consent Management
Build GDPR-compliant SaaS infrastructure: implement right-to-erasure pipelines that delete user data across all systems, manage consent with audit trails, handle data subject access requests (DSARs), and anonymize analytics data.
☁️Cloud & DevOpsAWS Lambda Optimization: Cold Starts, SnapStart, Memory Tuning
Optimize AWS Lambda functions for production: eliminate cold starts with SnapStart and provisioned concurrency, right-size memory with Lambda Power Tuning, use Lambda Layers for shared dependencies, and instrument with AWS Lambda Powertools for TypeScript.
🌐Web DevelopmentReact Suspense Patterns: Boundaries, Error Recovery, Streaming SSR
Master React Suspense in production: compose Suspense and error boundaries, stream HTML with React 18 streaming SSR, integrate with React Query and Next.js App Router, and avoid common pitfalls like waterfall fetching and missing error boundaries.
🌐Web DevelopmentDesign System Engineering: Token-Based Theming
Build a production design system: implement design token architecture with CSS custom properties, create a typed React component library, document with Storybook, automate visual regression testing with Chromatic, and publish with semantic versioning.
🌐Web DevelopmentNode.js Streams and Backpressure: Readable, Writable, Transform
Master Node.js streams for production: understand backpressure mechanics, implement readable and writable streams correctly, build transform pipelines for data processing, use the pipeline() API for error handling, and process large files without memory exhaustion.
🚀SaaS & StartupsSaaS Dunning Management: Failed Payment Recovery, Retry Schedules
