Phoenix framework development experts
Phoenix framework consequently ranks as the most loved web framework in the world, according to the largest annual Stack Overflow developers survey.
Curiosum was founded with the objective of delivering outstanding web development services, and to ensure that we can fulfill this commitment, we chose a technology stack that matches this ambition. That's how we picked Phoenix framework, built on top of Elixir programming language.
Our experts worked with 20+ worldwide tech innovators

Why Phoenix web framework?
Extraordinary Productivity
The Phoenix web framework is part of the rapidly growing Elixir ecosystem. Its straightforward syntax and structure, functional approach, and simplicity in debugging are among the features that contribute to its high productivity.
Built-in Scalability
A server using the Phoenix web framework automatically manages traffic load balancing thanks to the Erlang VM that Elixir uses under the hood. Consequently, there is no need to be concerned about horizontal scaling.
Solid Real-time features
Phoenix leverages the Erlang VM capabilities to support real-time features like WebSockets and server-sent events with its built-in PubSub system. Phoenix LiveView, part of the Phoenix framework ecosystem, takes this to the next level with instant UI updates based on events.
Incredible Ecosystem
Phoenix Framework is part of the larger Elixir ecosystem, giving access to a vast array of libraries and tools for tasks like database access, background job processing, and more. Plus, it has excellent tooling like Phoenix LiveView that makes this web framework such a pleasure to work with.
We're building exciting Phoenix framework-based applications with our clients

Curiosum enabled our team to develop a complete platform despite their lack of prior knowledge about Elixir stacks. In addition, their team impressed the client with their honesty, integrity, availability, and efficiency.

I'm very satisfied with the deliverables and impressed with the partnership. Curiosum is efficient and communicative team.

Curiosum helped us substantially to introduce OTP and caching concepts into out app as well as formulate the increasingly complex API in a concise manner. They played essential role in the development of our product.

Curiosum team have been great to work with, and we would certainly recommend them. Both of the developers we've had from them have been talented, hard working and a great asset to our team.

Curiosum team has adapted very well to the way we work and has been able to give valuable contribution to our overall product development.

Thanks to Curiosum, the platform now supports 10 times more users within the same server capacity. Also, external and internal stakeholders are happy with the quality of the application. Overall, the team works seamlessly through two-week sprints, using Slack and Jira for project management.

Finding experts in the tech stack we use - Elixir, Phoenix, React, GraphQL - is not easy. Curiosum understood our business perspective well and offered valuable feedback. That is exactly what we expect from our outsourcing partners.

After the paperwork, we start to review the code and project scope to prepare specific tasks and share our ideas regarding improvements.
Development & release
We're ready to work and the real development starts. Every feature development cycle involves programming, code testing, code review, quality assurance and deployment.
Quality is a must for us. Therefore, every project involves a thorough continuous integration process to minimize human errors.
Feedback
To make sure that both sides are satisfied with the work, we organize regular meetings. Thanks to the feedback loop, we can grow together.
Mistakes and problems may always happen. It's very important to discuss them as soon as they appear and solve them quickly. That's why we value constructive feedback very much.

The Phoenix framework, integral to our Phoenix web development services, is a web development tool built with Elixir, leveraging its robust features for building scalable and maintainable applications.
As a prominent Phoenix software house, we emphasize the seamless integration between Phoenix and Elixir, providing an environment that ensures enhanced productivity, reliability, and concurrency.
By utilizing Elixir's functional programming paradigm and its Erlang-based ecosystem, Phoenix offers superior performance and fault tolerance, making it ideal for real-time applications and complex systems. This synergy allows us to deliver high-quality solutions for your business.
To date, we've delivered Phoenix framework consulting and Phoenix web development services to more than 30 businesses, ranging from small firms to large corporations.
Each project has been a learning experience, providing us with new insights, patterns, and a clearer understanding of best practices and pitfalls.
Phoenix web development framework is suitable for both MVPs and scale-ups, offering a balance between productive development and scalability. Its main benefits include ease of use for developers, support for real-time updates, and efficient performance, which allow for rapid iteration and scaling. These characteristics make Phoenix a versatile choice for various project sizes and stages. For more insights, refer to our extensive guide about the Phoenix framework.
Phoenix serves as an exceptional choice for backend development; however, due to the rapid development of Phoenix LiveView, which includes component-based architecture, as well as real-time frontend updates, it also allows you to build rich, real-time user experiences without significant JavaScript overhead.
Phoenix web development framework is a perfect choice if you're looking for team specialized in one ecosystem, that can build both backend, and frontend in productive manner.
We heavily invest in numerous Phoenix framework-related activities to demonstrate our proficiency.
Below is a collection of resources you might find useful:
- Blog
- Resources page featuring podcast episodes, webinars, conferences
- Open source initiatives

As a Phoenix web development agency, we are committed to spreading knowledge within the community and acquiring new insights.
Beyond the resources mentioned, we foster collective learning via weekly internal lightning talks and the documentation of effective Phoenix framework practices that we continuously refine.
Phoenix stands out for its real-time functionalities, fault tolerance, and scalability, courtesy of its Elixir roots.
It is designed for high performance and can handle many connections simultaneously, making it perfect for applications requiring real-time updates, such as chat applications.
Additionally, its productive programming model and robust ecosystem simplify development, reducing time-to-market for new features or applications.
These features, combined with its efficiency and the ability to scale, distinguish Phoenix from other web frameworks that fail to deliver all of those things in one package.
