    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 for Your Needs

Brands are constantly evolving. To stay ahead in the digital age, they need a robust, secure, and innovative blockchain foundation. Enter blockchain developers—the masterminds who build and maintain these decentralized systems, ensuring your brand stays on the cutting edge of technology. Just as Canva designers use their tool to create eye-catching graphics, blockchain developers utilize various programming languages, frameworks, and platforms to develop, test, and deploy blockchain applications tailored to your business needs. 

When hiring a blockchain developer, it’s crucial to find someone who not only understands the technical aspects but also aligns with your project’s vision. Developers bring their own unique skill sets, such as expertise in Ethereum, Hyperledger, or smart contract development. Finding and hiring the best blockchain developer starts with understanding the role, evaluating the market demand and your budget, and crafting a well-thought-out job posting that attracts top talent. This guide will help you navigate the process of hiring the right blockchain developer to bring your brand’s innovative ideas to life.

Writing a blockchain developer job posting

Attracting the ideal blockchain developer starts with crafting a job post that speaks directly to their skills and interests. When creating your blockchain developer job posting, it’s essential to specify the type of projects and blockchain solutions you need and clearly outline the expertise and experience you’re seeking in a developer.

The following outline will help you create a job posting that covers all the necessary details:

Job post title

Effective job posts are clear and concise. Your blockchain developer job post title should immediately convey what you’re looking for. Consider these examples:

  • Blockchain developer (Ethereum specialist). Searching for a developer to create and deploy smart contracts on the Ethereum network for our decentralized finance (DeFi) platform.
  • Hyperledger developer. Hiring an expert in Hyperledger to design and implement a private blockchain network for our enterprise-level supply chain management system.
  • Blockchain security engineer. Need a developer with a strong background in cryptography to audit and enhance the security of our blockchain applications.
  • Smart contract developer. Seeking a developer experienced in Solidity to create and maintain smart contracts for our tokenized ecosystem.
  • Blockchain consultant. Looking for a blockchain expert to advise on integrating blockchain technology into our existing infrastructure and guide our transition to a decentralized system.

Project description

When writing your blockchain developer job post, be sure to include the following key elements:

  • Scope of work. Clearly outline the project’s objectives and specific deliverables. This might include developing smart contracts, creating decentralized applications (dApps), or building a private blockchain network. Be specific about the tasks and technologies involved, whether it’s working with Ethereum, Hyperledger, or another blockchain platform.
  • Project length. Estimate the project’s duration, including the expected number of hours or deliverables. Specify whether the project is a one-time task or if you’ll require ongoing support for maintenance, updates, or scaling.
  • Background. Indicate if you’re seeking candidates with particular backgrounds or specializations, such as experience in DeFi (decentralized finance), NFT development, or blockchain security.
  • Budget. Provide a budget range and indicate whether you prefer an hourly rate or a fixed-price contract. Make sure the budget aligns with the complexity and demands of the project.

Blockchain developer responsibilities

Include the core responsibilities for the blockchain developer role or project. Here are some examples:

  • Smart contract development. Write, test, and deploy smart contracts using Solidity or other relevant languages on platforms like Ethereum.
