Cutting edge engineering

Throughout this specialization, you will extend your knowledge of the C programming language, dig deeper into the Linux operating system.

The first three trimesters of our on-site intensive education covers the foundations of computer science and software engineering, including Linux, data structures, algorithms, low-level programming languages, high-level modern languages, databases, APIs, and DevOps.

You will also be challenged with advanced data structures and algorithms, and you will uncover all the mechanisms behind the blockchain technology by building your own basic cryptocurrency, from scratch.

Stytem Programming and Blockchain will equip you to be well-versed in C, Linux kernel (signal, thread, file stream, IPC, ELF, etc.), advanced trees, graph, pathfinding, cryptography, block mining, blockchain, and more.

This specialization builds a solid foundation for students who aim to become capable, well rounded Software Engineers who are as comfortable programming a blockchain as they are developing on embedded systems and self-driving cars.

Typical job titles could include: Software engineer, embedded system programmer, SRE, Junior Blockchain engineer.

The last sprint is dedicated to building a personal web project on the technology of a student's choice.

“I chose Holberton because they accept people based on their potential, not past experience. I graduated in Theology, which is pretty far from computer programming, but I am now studing how to become a software engineer because Holberton could see my drive and how well I could learn.”
