What should you know before hiring Blockchain Developers from Blockchain Development companies or Freelance platforms.
Leewayhertz is an enterprise & startup software development company that creates digital solutions based on new technologies to help businesses simplify the process of implementing technology products. Such companies stick to the "you dream it: we build it" motto in their work.
Founded in 2007, the company successfully entered the market and has since received a large number of awards (e.g. TOP Developers 2019, TOP loT App developers 2020, TOP App Developers USA 2019, etc.). Leewayherts is trusted by major brands like Siemens, Disney, Pepsico, and others. Its experience is more than 30 Fortune 500 companies, which hints at the impeccable performance.
Leewayhertz’s blockchain developers have worked in various industries including consumer electronics, financial technology, healthcare, insurance, logistics, tourism, manufacturing, education, and EdTech.
What Leewayhertz Offers to Its CustomersThe company has plenty of blockchain solutions and additional features to choose from as follows:
- Blockchain applications. In this sector, the firm provides a range of services from consulting to deployment, maintenance, and migration;
- Blockchain consulting. Need a comprehensive roadmap? Leewayhertz will help you launch a successful product, i.e. choose a blockchain platform and come up with an idea for the project. It will also analyze the potential of your idea and determine the right solution for implementation;
- Smart contract development. Businesses turn to smart contract development for event automation, autonomy, savings, and accuracy. Blockchain developers create smart contracts architectures, audit, optimize, design, and develop them;
- Blockchain wallet. Leewayhertz's specialists take a smart approach to blockchain wallet application development. With this solution, any business will be able to track transactions and check the balance at any time;
- Stablecoin development. Cryptocurrency developers are experts in creating stable coins and using an intelligent approach when creating a development strategy.

Leewayhertz uses the following latest technologies in all development processes:
- Machine learning;
- Computer vision;
- Blockchain;
- Voice skills;
- Robotic process automation;
- Artificial intelligence, etc.
What is the blockchain development process? For Leewayhertz, this means defining the problem, goal, and the right platform. This also includes forming an idea and business requirements, as well as developing a proof-of-concept. Moreover, it's a clear structure of actions, coordinated work of specialists, and constant (effective) communication with clients.
Leewayhertz: Working with ClientsA successful software application is not only the result of the work of experienced and qualified specialists - but it's also about effective business communication channels. That's why Leewayhertz uses a variety of ways to communicate with their clients, e.g. Slack, Zoom, and Jira Support. In their turn, Confluence and Jira are also used internally in the company.
Thus, Jira helps blockchain developers plan and allocate tasks between teams, track project status, and assess the progress of a particular specialist working on a project. In turn, Confluence helps collect documents, knowledge in one place, which allows you to complete projects on time.
What Do Clients Say about Leewayhertz?Since the company has been offering its services in the market since 2007, it has accumulated a lot of reviews, as well as experience working with large brands. Most client reviews are positive, and the average rating on the review sites is 4.3 out of 5, which is 100% justified.
Reviewers unequivocally recommend Leewayhertz and note quality work at affordable prices, flexibility on approaches, contribution to successful development in the shortest possible time, employee responsiveness, and quality tech support at all stages of work.
