Custom App Development


Custom App Development

If you want to develop peer-to-peer decentralized applications, dApps or self-executing smart contracts, our development teams help you deliver custom blockchain software solutions with our hands-on experience in blockchain technology.


Custom Development

We recognize that every business and industry is different, which is why our experts work to build software solutions tailored to your needs. Whether you need an e-commerce platform, mobile application, blockchain, AWS cloud solutions, or enterprise platforms, we are here to help. The Rumble Fish team is a group of passionate IT experts who firmly believe that technology can take your business to the next level. We will take responsibility for the entire project and offer an integrated range of services to guarantee a smooth project. You bring the product vision, and we bring the building expertise, specializing in Blockchain and AWS Cloud solutions. We have helped both large enterprises and SMEs in Fintech, Crypto, Healthtech, Logistics, Transportation, and Hospitality to transform their operations with custom projects and software. Rumble Fish can run your project from start to finish, from understanding the objectives to choosing the right infrastructure and technology stack, all the way through to testing and deployment.

How does it work? There are four core stages of developing a custom App.

  • Understanding your requirements

  • Project Analysis and MVP

  • Development and deployment

  • Auditing and consulting

Understanding your requirements

Most importantly, we need to get an understanding of your requirements. Don’t worry, we can handle all the technical jargon, so you don’t have to be an expert. The requirements will help us create a plan for the development of your application. Larger projects sometimes require a more comprehensive analysis but doing it thoroughly at this stage will ensure you save time when it comes to implementation as there is less chance of bugs.

Rumble Fish can offer both on-site and online Discovery Workshops for our clients. In the workshops, we will have multiple sessions, allowing everyone the opportunity to discuss and develop the project in collaboration. We will come up with an initial timeline and costs before delving into a more in-depth project analysis. 

After the Discovery Workshop we want to have an open relationship with our clients to turn their ideas into a reality. 

Project Analysis and MVP

After we agree on what needs to be developed with you, we can put a roadmap in place to build a minimum viable product. The MVP is essential to get a prototype of your application and demonstrate it’s core functionality, rather than diving into something that isn’t quite right. Using the MVP, we can verify the project against the user needs and get the go-ahead to continue with a full deployment. 

Some projects may start with minimal Rumble Fish developers working with the client to establish viable solutions. During the course of the project, we can deploy more resources as required and even own the whole process. We can work on full technology stacks with knowledge in NodeJS, NestJS, Express, Kafka, React, Redux, Material UI, and many more. Our back-end models tend to be based on the model of services run on the ECS Cluster (Amazon Web Services) but can be tailored to meet your project requirements. We follow the Infrastructure as Code (IaC) principle that ensures the high maintainability of our solutions.

Development and deployment

Until the final release, our team of experts with develop in agile, iterative cycles and keep you up-to-date with the progress. Any software we build goes through granular testing and quality assurance processes to ensure there are no bugs, and it performs at an optimal level. You will have ownership of any code and access to our ongoing customer support. 

Auditing and consulting

Once we deliver a project, we don’t just leave it with you and run! Our experts are always on hand for ongoing support and advice on how to scale up your solutions. If you want to start with an MVP project, that’s fine with us, and we will be happy to support the full solution further down the line.
