      Chatbot Solution Review from Daria Hlavcheva

      KeenEthics onboarded Lionwood Software to develop an AI-powered chatbot that could analyze photos of vehicle damage and provide an estimated repair cost for insurance company. The project focused on applying AI to a traditionally manual part of the insurance claims process. The solution needed to interpret car damage from uploaded images, identify relevant damage, and translate the analysis into a cost estimate that could support faster and more consistent claims assessment. Lionwood Software took ownership of the AI development and worked closely with the KeenEthics team to align the solution with the product requirements and insurance use case. Their team demonstrated a strong understanding of both the technical challenges of image-based damage assessment and the business logic behind insurance claims. They were proactive in discussing requirements, clarifying edge cases, and addressing dependencies throughout the development process. The resulting solution helped automate an important part of the vehicle damage assessment workflow, reducing the need for purely manual evaluation and creating a foundation for faster claims processing. Lionwood Software proved to be a reliable technology partner with the expertise to work on AI-driven products where technical implementation needs to be closely aligned with real-world business requirements.

      Software Development Review from Iryna Liashko

      We engaged Acropolium as a development partner to support delivery of a SaaS-based warehouse management system for our end client. They handled key backend components, third-party integrations, and overall system architecture alignment. The engagement ran from May to September 2025. Acropolium took full ownership of complex technical components and worked as a seamless extension of our internal team from day one. They required minimal supervision, communicated proactively, and adapted well to changing requirements throughout the project. The results were strong: our end client saw a 30%+ improvement in order processing efficiency, a significant reduction in manual operations and errors, and smooth integration with existing systems. We were thoroughly impressed by their technical quality, reliable delivery, and professional approach. Deadlines were consistently met, and the team responded quickly to feedback. The collaboration was smooth from start to finish. We would confidently work with Acropolium again and highly recommend them as a trusted software development partner.

      Node.js Review from Oleksandr Romanov

      We partnered with the team to support the integration of AI capabilities into our existing Node.js tech stack, and the experience exceeded our expectations. From the very beginning, they demonstrated a strong understanding of both backend architecture and modern AI tools, which allowed them to quickly align with our business goals. Their approach was structured and transparent: they helped us choose the right AI models, designed scalable integration flows, and ensured smooth interaction between services without compromising performance. Communication was consistent, deadlines were met, and any challenges were addressed proactively. What stood out the most was their ability to bridge the gap between complex AI concepts and practical implementation within a real production environment. As a result, we significantly improved our products functionality and reduced time-to-market for new features. I would highly recommend this team to anyone looking to integrate AI into a Node.js-based system in a reliable and efficient way.

I have only good comments about QIT as employer, starting from interview process you feel that people interested in making the best workplace for you. There are no boundaries or vertical structure, you can discuss any of your issues or concerns with CEO directly and be sure that management will make anything possible to tackle it. Overall, I have a good impression of this company and would recommend anyone to consider it.

      Good morning, I had attended the interview here for the role of Associate Software developer. As, a fresher I was happy with my performance. After 2 days I got the rejection mail. Later when I asked the feedback I was told that my communication skills are good but I need to work on my technical skills. May be not in my destiny. Thank you

      Amazing interview experience. All the interviews are scheduled less than a 2 week.The best thing that I like is the HR itself calls me and for some reason I did not received call then she text me "please call me". Which is really good and amazing.

7 Frequently Asked Questions About Blockchain Development Companies

What services do blockchain development agencies offer?

Blockchain development agencies design, build, and support blockchain-based solutions that automate processes, improve transparency, and enable secure digital transactions. 

Common services include: 

  • Smart contract development and auditing: Writing self-executing code and reviewing it to prevent bugs, exploits, or costly failures  
  • dApp development: Building decentralized apps that run on blockchain networks instead of centralized servers  
  • Token development and NFT platforms: Creating digital tokens, cryptocurrencies, and marketplaces for trading assets  
  • Blockchain integration: Connecting blockchain with existing systems like web apps, enterprise software, or cloud platforms  
  • Private and enterprise blockchain solutions: Setting up custom networks for businesses that need control, privacy, and scalability  
  • Blockchain consulting: Advising on use cases, architecture, and whether blockchain is the right fit  
  • Wallet development: Building secure wallets for storing and managing digital assets  
  • Maintenance and support: Monitoring performance, fixing issues, and updating systems after launch 

What platforms do blockchain developers use?

Blockchain development firms use a mix of public networks, enterprise platforms, and developer tools to build, deploy, and manage blockchain solutions. They choose platforms based on speed, cost, scalability, and whether the project needs a public or private network. 

Key platforms and networks: 

  • Ethereum: The most widely used platform for smart contracts and decentralized applications  
  • Solana: Built for high speed and low fees, often used for scalable dApps and marketplaces  
  • Avalanche: A flexible platform that supports custom blockchain networks and fast transaction finality  
  • Hyperledger Fabric: Designed for private, permissioned systems used by enterprises  
  • Corda (R3): Common in finance and regulated industries where data privacy is critical  
  • IBM Blockchain: Enterprise-grade solution built on Hyperledger for secure business use cases  

Development tools and infrastructure that blockchain development agencies use: 

  • Node providers (e.g., Alchemy, Infura, QuickNode): Give developers access to blockchain networks without running their own nodes  
  • Smart contract tools (e.g., Remix IDE): Used to write, test, and deploy contract code  
  • Frameworks and CLIs (e.g., Ignite CLI): Help set up and manage blockchain projects faster 

How much do blockchain companies charge for their services?

Blockchain development companies typically charge from $40,000 to $300,000+ for a full solution, depending on complexity, features, and security requirements. 

Cost by project complexity 

The biggest cost driver is the solution's complexity, from basic smart contracts to full-scale platforms. 

  • Simple blockchain apps: $40,000 to $60,000 
    Basic features like simple smart contracts or payment functionality  
  • Mid-level applications: $60,000 to $150,000 
    dApps with user roles, integrations, and moderate decentralization  
  • Complex blockchain systems: $150,000 to $300,000+
    Enterprise platforms, advanced security, custom architecture 

Cost by solution type 

Different blockchain products have different price ranges based on functionality. 

  • dApps: $35,000 to $150,000  
  • NFT marketplaces: $55,000 to $125,000  
  • Crypto wallets: $125,000 to $200,000  
  • Crypto exchanges: $135,000 to $190,000  
  • DAO platforms: $10,000 to $30,000 

Cost breakdown across the project 

Your budget is split across multiple phases, not just development. 

  • Consulting and planning: 5%  
  • UI/UX design: 10%  
  • Core development: 45%  
  • Testing and QA: 25%  
  • Deployment and maintenance setup: 15% 

Final pricing depends on scope, security level, integrations, and whether you build on an existing blockchain or create a custom one. 

What are the ongoing costs of maintaining a blockchain solution?

Ongoing blockchain costs typically range from 15% to 25% of the initial development cost per year, depending on system complexity and usage.  

Key ongoing costs include: 

  • Maintenance and updates: Bug fixes, performance improvements, and feature upgrades  
  • Infrastructure: Node providers, cloud services, and storage as usage grows  
  • Security: Regular audits, monitoring, and protection against vulnerabilities  
  • Transaction fees: Ongoing network or gas fees for processing transactions  
  • Support and operations: Technical monitoring, DevOps, and user support  
  • Compliance: Legal, regulatory, and data protection requirements  

Costs increase as the system scales, handles more transactions, or requires higher security. 

How long does it take to build a blockchain solution?

The best blockchain development company typically needs 3 to 9+ months to build a blockchain solution, depending on complexity, features, and security requirements. 

Typical timeline by complexity: 

  • Simple solutions: 1 to 2 months 
    Basic wallets or simple smart contract apps  
  • Mid-level projects: 2 to 4 months 
    dApps with integrations and user functionality  
  • Complex systems: 4 to 9+ months 
    DeFi platforms, marketplaces, or enterprise solutions  

Blockchain development agencies build products in stages, and each is adding time: 

  • Planning and requirements: 1 to 2 weeks  
  • Architecture and design: 2 to 4 weeks  
  • Development: 1 to 6 months  
  • Testing and QA: 2 to 4 weeks  
  • Deployment: 1 to 2 weeks 

Factors that affect the timeline include scope and feature set, choice of blockchain platform, team experience, and whether you build from scratch or use existing tools.

What is the difference between public and private blockchains?

Public blockchains are open to anyone, while private blockchains are restricted to approved users and controlled by an organization. 

You can see the main differences in the following table: 

Feature Public blockchain Private blockchain
Access Anyone can join Permission required
Control Decentralized Controlled by one entity or group
Transparency Fully transparent Limited visibility
Speed Slower Faster
Cost Higher (transaction fees) Lower
Security High through decentralization High, but depends on governance
Use cases Crypto, DeFi, NFTs Enterprise systems, internal operations

How do blockchain development agencies ensure security?

Blockchain development firms ensure security by combining secure coding, testing, and continuous monitoring to prevent vulnerabilities and protect data and transactions. 

Key security practices include: 

  • Smart contract audits: Reviewing code to detect bugs, exploits, and logic flaws before deployment  
  • Secure development practices: Using proven frameworks, code standards, and peer reviews  
  • Encryption and key management: Protecting data with cryptography and secure storage of private keys  
  • Testing and simulation: Running stress tests and attack scenarios to identify weaknesses  
  • Access control: Limiting permissions and enforcing authentication for users and systems  
  • Ongoing monitoring: Tracking activity, detecting threats, and applying updates or patches quickly  

Security is built into every stage, not added after deployment.
