Roadmaps

Roadmaps that take you from zero to senior

Each roadmap is a curated sequence of topics, guides, and projects. No fluff — just the path the best engineers actually take.

Backend Engineering

Design robust APIs and services. From language fundamentals to distributed systems.

1 Java
Master the language: syntax, OOP, collections, generics, and concurrency.
2 Spring Boot
Build production REST APIs with dependency injection, data, and security.
3 Databases
Model data and query relational stores with JDBC and JPA.
4 Kafka
Stream events at scale with producers, consumers, and Kafka Streams.
5 System Design
Scale services with caching, queues, sharding, and resilience patterns.

Craft fast, accessible interfaces with modern component architecture.

1 JavaScript
The language of the web: types, async, DOM, modules, and the browser.
2 React
Component-driven UIs with JSX, props, state, and hooks.
3 State Management
Manage local, global, and server state with Context, Redux, and TanStack Query.
4 Performance
Tame re-renders with memoization, code splitting, and concurrent features.
5 Testing
Test components and hooks with React Testing Library and Vitest.

Build full-stack JavaScript apps end to end with MongoDB, Express, React, and Node.js.

1 Node.js
Master the server runtime: modules, the event loop, async I/O, and npm.
2 Express.js
Build REST APIs with routing, middleware, validation, and auth.
3 MongoDB & Mongoose
Model documents, query collections, and connect with Mongoose ODM.
4 React
Craft the client with components, hooks, routing, and data fetching.
5 Full-Stack Integration
Wire the SPA to the API: CORS, JWT auth, deployment, and project structure.

Deliver enterprise full-stack apps with MongoDB, Express, Angular, and Node.js.

1 Node.js
The runtime foundation: event loop, streams, async patterns, and tooling.
2 Express.js
API layer with routing, middleware, error handling, and security.
3 MongoDB & Mongoose
Document modeling, schemas, and data access from the Node backend.
4 Angular
Build the front end with components, services, RxJS, and the router.
5 Full-Stack Integration
Connect Angular to the API with HttpClient, interceptors, and JWT auth.

Architect resilient, cost-efficient systems on the cloud.

1 AWS Core
Compute, storage, and the core services every cloud app relies on.
2 Networking
Design secure networks with VPCs, subnets, routing, and gateways.
3 IAM & Security
Control access with least-privilege roles, policies, and identities.
4 Serverless
Run code without servers using Lambda, API Gateway, and events.
5 IaC
Provision and version infrastructure declaratively with Terraform.

Run Linux servers, ship apps to production, and automate everything in between.

1 Linux & Ubuntu
Master the command line, users, permissions, services, and packages on Ubuntu.
2 Web Servers & Domains
Serve sites with Nginx and Apache, set up reverse proxies, domains, DNS, and SSL.
3 Databases
Install and operate PostgreSQL, MySQL, MongoDB, and Redis on your own servers.
4 Containers
Package apps into portable images and run them as containers with Docker.
5 CI/CD
Automate build, test, and deploy pipelines for fast, safe releases.
6 Monitoring & SRE
Observe systems with metrics, logs, traces, alerting, and reliability practices.

Scale to millions. Caching, sharding, queues, and trade-offs that matter.

1
Scalability

Scale horizontally with load balancing, sharding, and stateless design.
2
Caching

Cut latency and load with layered caching and invalidation strategies.
3 Data Modeling
Choose data stores and model schemas for access patterns and scale.
4 Messaging
Decouple services with queues, streams, and event-driven design.
5
Resilience

Survive failure with retries, timeouts, circuit breakers, and redundancy.
