Learn to build a production-ready travel agent help desk system using Next.js for the frontend, Rust for a GraphQL backend with shift scheduling and Agora token generation, and Agora RTM/RTC for real-time chat and video escalation. Implement smart round-robin agent assignment, admin overrides, and tenant isolation.
This tutorial walks through building a budget variance analysis platform for finance teams using Next.js 16 as the frontend, a Rust GraphQL backend with async-graphql, and a complete DevOps pipeline from local Docker Compose to production blue-green deployments via GitHub Actions. You'll learn how to structure a Rust service for complex financial calculations, integrate it with Next.js server components, and automate multi-architecture builds with zero-downtime deployment.
Learn to build a production-ready payroll dashboard for HR teams using Next.js 16, a Rust GraphQL backend, and Docker. The system handles salary, tax (PPh 21), and BPJS calculations dynamically based on query parameters, with a full CI/CD pipeline via GitHub Actions.
Build a production-grade observability stack for a distributed blog engine (animal-themed services). You'll instrument Go services with custom Prometheus metrics, configure Grafana dashboards with alert annotations, and implement AlertManager with inhibition rules, routing to Slack/Email, and multi-region federation. This tutorial moves beyond basic setup into real-world scaling patterns.
Compare three production-grade zero-downtime deployment strategies in Kubernetes. Implement RollingUpdate, Blue-Green, and Canary patterns using a city-themed load-balanced service, with real-world trade-offs, health checks, and traffic management.
Move beyond basic ownership rules. This recipe-style tutorial teaches advanced Rust ownership patterns—lifetime annotations for zero-copy string slicing, interior mutability with RefCell, and method receiver optimization—by refactoring a real command-line file organizer themed around ocean creatures.
Move beyond beginner Ansible and build a production-grade deployment pipeline for a containerized microservice. You’ll write reusable playbooks that handle build, test, rollout, health checks, and rollback across staging and production environments, leveraging Ansible’s native modules and best practices from real-world DevOps teams.
Master conditional types, distributive conditionals, mapped types with key remapping, branded types, and the infer keyword. Build a flexible report engine for gemstone valuation that validates data transformations at compile time and eliminates runtime errors.
Learn to build a production-grade CI/CD pipeline for a scalable cloud infrastructure using GitHub Actions. This advanced guide covers multi-architecture Docker builds (AMD64 + ARM64), layer caching, semantic versioning, approval-gated deployment, and rollback strategies — all with a real-world microservices project themed around Australian cities.
