Software Development Review from Harshal Chhajed
They have highly skilled support staff for faster resolution which leads to customer satisfaction. Also, it has many features including IoT and blockchain apart from regular software development. If there are any changes in the scope of the project at a later stage, it can prove quite costly and also difficult to accommodate last-minute client-side scripting changes. They are versatile, cost-effective, and offer quick customer support. They offer a very customized software development tool where business needs can be addressed. It is very cost-optimized and hence can help generate good returns for business investment.

Phenomenal team to work with. From Sales to Engineering, Customer Service and at the highest level of leadership, the DualBoot partner team is simply great.
They are consistent and interested in your success. Once their engineering team has learned your stack, you can't tell from inside to external resources. Work just gets done. I recommend them w/o reservations; start-up or well established firm, you are in great hands with the DualBoot team!

Thomas Booth's Review Sourced from Google
I recently had an experience back in 2022 with Apadmi that I feel compelled to share and have debated whether i should post this. As a professional eagerly looking forward to an interview with Apadmi, I was unfortunately met with a series of disappointments.
Firstly, the structured process I was initially promised for the interview was not adhered to. This lack of organisation not only threw me off but also made it challenging to present myself effectively and forced to do a presentation in less than 24 hours notice.
More concerning, however, was my interaction with the Managing Director, not sure if he is still there. I found his demeanour not just unprofessional but outright rude. This was disheartening, especially coming from a leadership figure in a reputable company. I've actually never been so humiliated in the professional environment.
It's important for companies to remember that interviews are a two-way process. They are not just about evaluating candidates, but also about demonstrating the company's values and culture. Unfortunately, my experience with Apadmi fell short of the professional standards one would expect, however i would say Marcus, one of the board members was a delight in my first stage.
I hope my feedback is taken constructively, as it is intended to highlight areas where there is significant room for improvement in how Apadmi manages its recruitment process and senior staff interactions.

Manoj Ranaweera's Review Sourced from Google
Apadmi's ability to spin out technology as separate companies is remarkable. A strong supporter of Manchester tech ecosystem, they became unbeatable in mobile category during the first three years of northern tech awards before it adopted a new structure and ownership. Another remarkable achievement is that the four founders have remained together during all these years. I wish them all the best.

Smart contract development and auditing: Writing self-executing code and reviewing it to prevent bugs, exploits, or costly failures Â
dApp development: Building decentralized apps that run on blockchain networks instead of centralized servers Â
Token development and NFT platforms: Creating digital tokens, cryptocurrencies, and marketplaces for trading assets Â
Blockchain integration: Connecting blockchain with existing systems like web apps, enterprise software, or cloud platforms Â
Private and enterprise blockchain solutions: Setting up custom networks for businesses that need control, privacy, and scalability Â
Blockchain consulting: Advising on use cases, architecture, and whether blockchain is the right fit Â
Wallet development: Building secure wallets for storing and managing digital assets Â
Maintenance and support: Monitoring performance, fixing issues, and updating systems after launchÂ
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.Â
Key platforms and networks:Â
Ethereum: The most widely used platform for smart contracts and decentralized applications Â
Solana: Built for high speed and low fees, often used for scalable dApps and marketplaces Â
Avalanche: A flexible platform that supports custom blockchain networks and fast transaction finality Â
Hyperledger Fabric: Designed for private, permissioned systems used by enterprises Â
Corda (R3): Common in finance and regulated industries where data privacy is critical Â
IBM Blockchain: Enterprise-grade solution built on Hyperledger for secure business use cases Â
Development tools and infrastructure that blockchain development agencies use:Â
Node providers (e.g., Alchemy, Infura, QuickNode): Give developers access to blockchain networks without running their own nodes Â
Smart contract tools (e.g., Remix IDE): Used to write, test, and deploy contract code Â
Frameworks and CLIs (e.g., Ignite CLI): Help set up and manage blockchain projects fasterÂ
How much do blockchain companies charge for their services?
Simple solutions: 1 to 2 months Basic wallets or simple smart contract apps Â
Mid-level projects: 2 to 4 months dApps with integrations and user functionality Â
Complex systems: 4 to 9+ months DeFi platforms, marketplaces, or enterprise solutions Â
Blockchain development agencies build products in stages, and each is adding time:Â
Planning and requirements: 1 to 2 weeks Â
Architecture and design: 2 to 4 weeks Â
Development: 1 to 6 months Â
Testing and QA: 2 to 4 weeks Â
Deployment: 1 to 2 weeksÂ
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.Â
You can see the main differences in the following table:Â
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.Â
Key security practices include:Â
Smart contract audits: Reviewing code to detect bugs, exploits, and logic flaws before deployment Â
Secure development practices: Using proven frameworks, code standards, and peer reviews Â
Encryption and key management: Protecting data with cryptography and secure storage of private keys Â
Testing and simulation: Running stress tests and attack scenarios to identify weaknesses Â
Access control: Limiting permissions and enforcing authentication for users and systems Â
Ongoing monitoring: Tracking activity, detecting threats, and applying updates or patches quickly Â
Security is built into every stage, not added after deployment.Â
