This course IS NOT like any other Ethereum and Solidity Programming course you can take online. At the end of this Hands-On Course, you will MASTER all the key concepts of Ethereum and Solidity and you will become an effective Ethereum Blockchain Developer for the future that comes.

Just starting out with Ethereum Smart Contracts Development and Solidity Programming? Perfect, you are covered! This course starts out assuming you’re new to these technologies.

Or maybe you’ve already tried to learn Ethereum Blockchain Development and Solidity Programming by yourself and now you want to put all the pieces together? I’m here to help you, this course has everything you need to know about Ethereum Blockchain Development and Solidity Programming Language.

You’ll have lifetime access and you can return and look for a specific Ethereum feature or Solidity syntax anytime you want.

All presentations and Ethereum Smart Contracts used in this course are available for download.

Many Ethereum Smart Contracts such as the ERC20 Token, the ICO are ready to be used with none or very few changes.

There are many courses on Ethereum Blockchain Development and Solidity Programming. Why should you learn from me?

  • I’m a Practitioner and a Blockchain Enthusiast. Welcome to the real world! I have almost 20 years of experience as a Software Engineer. Since I’ve started with Ethereum and Blockchain Development, I’ve been using or studying technology almost on a daily basis.
  • I’m an Educator and I know how to make a syllabus. For the last 10 years, I’ve trained thousands of people on Linux, Networking, Security, or Programming.

This course doesn’t cover JavaScript Frameworks, Front-Ends, or details about Web3 interaction with the Ethereum Blockchain. It’s focused on Back-End Smart Contracts Development. Basic knowledge of any programming language (C, C++, JavaScript) is required!


  • “Very detailed and well explained. Andrei completely broke down the barriers to understand Solidity programming, so many basics that are fundamental to understanding this tech were clearly explained. Very Impressive!” by Peter Olisa
  • “Highly recommended course. Goes directly to the point, explaining many examples of real-life smart contracts. Instead of a lot of JavaScript front-end programming, as in other courses, it goes directly to dApp development. Very useful indeed.” by Jose Ferdandez
  • “The course is well structured and really in-depth. The instructor does a really good job explaining the concepts, with examples. I would recommend this course to anyone interested in the subject.” by Andrei Buiu

The topics covered in this course are:

  • What is Ethereum Blockchain Platform
  • Ethereum Accounts, Addresses, Transactions & Blocks, Gas, Opcodes, and Mining
  • Tools used for Ethereum Development
  • Ethereum Smart Contract Compilation, ABI, Bytecode, and Deployment to different Ethereum Blockchains
  • Solidity Syntax
  • In-depth details about Solidity State Variables and Functions
