    I have over 3 years of experience as a Solidity and React.JS developer, 4 years of experience as a Software Engineer, over 10 years of experience in general programming and have Master's degree in Computer Science. I can create multiple custom DEFI solutions and also fork existing ones. Blockchain development is a very complicated and sensitive business and you should choose to work with professionals that develop safe and tested smart contracts. Having an untested and poorly written smart contract can put your users funds in danger and ruin your entire project. Some of the many projects which I've built in the past are: • NFT launches/drops : regular, whitelisted, gasless whitelisting using wallet signatures, Merkle Tree etc. • NFT staking, merging etc. • ERC20 token ICOs: regular, whitelisted, gasless whitelisting • ERC20 tokens with custom specifications: burnable, tax fee on buying/selling etc. • DeFi forks of platforms (Uniswap, Pancakeswap and others) • Creating a bridge for wrapping NFTs and ERC20 tokens between chains • Custom smart contract solutions I am highly capable of building you full custom solutions on Ethereum, Binance Smart Chain, Polygon and many other chains. Other languages I have been coding over the years are: C++, C, Python, Javascript, DevPascal, Java, Kotlin, Rust, Matlab.

How to Hire Top Blockchain Developers

What is a blockchain developer?

From cryptocurrencies to initial coin offerings (ICOs), smart contracts, and supply chains, the blockchain promises better security, transparency, and accountability to the business world. If you’re looking for a freelancer who can help you implement your own blockchain, consider hiring a blockchain developer.  

How do you hire a blockchain developer?

You can source blockchain developers on Upwork by following these three steps:

  • Write a project description. You’ll want to determine your scope of work the skills and requirements you are looking for in a blockchain developer.
  • Post it on Upwork. Once you’ve written a project description, post it to Upwork. Follow the prompts to help you input the information you collected to scope out your project.
  • Shortlist and interview blockchain developers. Once the proposals start coming in, create a shortlist of the candidates you want to interview. 

Of these three steps, writing your project description is the most important. It’s where you will determine your scope of work, the specific type of blockchain developer you need for your project, and your budget.

How much does it cost to hire a blockchain developer?

Rates can vary due to many factors, including expertise and experience, location, and market conditions.

  • An experienced blockchain developer may command higher fees but also works faster, has specific areas of expertise, and delivers higher-quality work.
  • A contractor who builds a client base may price services more competitively.

Rates charged by blockchain developers on Upwork are:

  • Beginner: $30 per hour
  • Intermediate: $45 per hour
  • Advanced: $59 per hour

Why hire a blockchain developer?

The trick to finding the best candidate is to identify your needs. 

  • Blockchain developers can assist with technology integration into business processes. This can lead to the improvement of operational efficiency and productivity. 
  • Experienced specialists can help develop hack-proof apps or platforms to guarantee fast and safe exchange of digital currencies. 
  • Experts in blockchain technology are always up-to-date with the latest trends. This allows them to build effective strategies for their clients to achieve short and long-term goals. 

Why blockchain matters

First, what is blockchain? In short, it is a distributed database designed to ease transactions and keep track of assets. This may seem like a straightforward goal, but it is a problem for consumers, businesses, financial institutions, and governments.

These inefficiencies can slow down the pace of business, leading to lost revenue for individual companies and lower growth for the economy as a whole. Blockchain has the potential to solve many of these problems.

Blockchain developer FAQ

How do you write a blockchain developer job post?

Your job post is your chance to describe your project scope, budget, and talent needs. Although you don’t need a full job description as you would when hiring an employee, aim to provide enough detail for a contractor to know if they’re the right fit for the project.

Job post title

Create a simple title that describes exactly what you’re looking for. The idea is to target the keywords your ideal candidate will likely type into a job search bar to find your project. Here are some sample blockchain developer job post titles:

  • We are looking for a seasoned blockchain developer 
  • A junior blockchain developer is needed
  • A fintech company is looking for a blockchain DevOps engineer

Project description

An effective blockchain development job post should include the following: 

  • Scope of work: List all the deliverables you’ll need, from smart contracts to supply chains.
  • Project length: Your job post should indicate whether this is a smaller or larger project.
  • Background: If you prefer experience working with productivity tools, blockchain protocols, or other technologies, mention this here.
  • Budget: Set a budget and note your preference for hourly rates vs. fixed-price contracts.

Blockchain developer responsibilities

Here are some examples of blockchain developer job responsibilities:

  • Research, design, and test blockchain technologies 
  • Work with the development team and project managers to architect the necessary infrastructure
  • Ensure data configuration follows security protocols, privacy documents, and other requirements. 

Blockchain developer requirements and qualifications

Be sure to include any requirements and qualifications you seek in blockchain development. Here are some examples:

  • Programming languages such as Solidity (for Ethereum), C++, Java, JavaScript, etc.
  • Popular blockchain development platforms such as Ethereum, Hyperledger, etc.
  • Database languages such as SQL
  • Application-specific knowledge (e.g., cryptocurrencies, smart contracts, ICOs, etc.)
