Custom C++ String Class

Reimplementation of std::string from scratch

A lightweight, from-scratch reimplementation of C++'s std::string class using only core C++ features. Demonstrates advanced concepts: Rule of Five, operator overloading, dynamic memory management, move semantics, and exception safety.

Before

A workflow or idea that needed clearer structure, validation, and delivery.

After

A working product surface with defined features, links, and a reviewable case study.

Engineering challenges

  • Keeping the implementation clear enough to explain while still solving the core technical problem.
  • Choosing a scope that could be shipped, tested, and documented.
  • Turning technical work into proof a visitor can evaluate quickly.

Results

  • Mastered C++ class design, memory lifecycle, and OOP principles
  • Documented the engineering path and important learnings.
  • Made source code or technical proof available for review.
