OCaml Technical Interview Prep
Prepare for OCaml interviews: language deep-dives, common questions, coding challenges, and how to stand out.
Idiomatic OCaml & Best Practices
Write OCaml the way experts do: idioms, conventions, anti-patterns to avoid, and production-grade best practices.
Scala Foundations
Start Scala from zero. Set up your environment, learn the core syntax, and write your first working programs with confidence.
Core Scala
Go beyond the basics of Scala: data types, collections, error handling, and the standard library you reach for every day.
Intermediate Scala
Level up your Scala. Write idiomatic, well-structured code and solve real problems with the right tools and patterns.
Advanced Scala
Master advanced Scala: deep language features, metaprogramming, internals, and the techniques senior engineers rely on.
Functional Programming in Scala
Apply functional techniques in Scala: pure functions, immutability, higher-order functions, and composition.
Concurrency & Parallelism in Scala
Write fast, correct concurrent Scala: threads, async, synchronization, and avoiding race conditions and deadlocks.
Testing & TDD in Scala
Ship reliable Scala: unit and integration tests, mocking, and test-driven development workflows.
Design Patterns in Scala
Apply battle-tested design patterns in Scala to write flexible, maintainable, and extensible software.
Scala by Building Projects
Learn Scala by shipping real projects. Each one adds a new skill and something concrete to your portfolio.
