Custom App Development Services: Web and Mobile App Development

Give your application a strong foundation. We start by identifying market opportunities and user needs to design an effective digital product. We also invest in developing a UX strategy and UI design that will resonate with your users and increase your chances of success.

We have expertise in a range of technologies and frameworks for custom software. This allows us to identify the right path to follow for your custom app development. Whether it’s choosing between native and React Native, ChakraUI and Angular Material, or RxJS and SWR, we will help you make the right decisions for your digital product.

Unlike most other custom web application development companies, we offer cybersecurity services for apps and software as one of our product offerings. This makes us uniquely qualified to design inherently secure apps for you. Additionally, our cybersecurity testing makes sure all apps we build can defend against malicious attacks.

Is your custom app part of a larger tech ecosystem? Our integration services help you seamlessly connect your new technology solution to your existing systems with custom-built APIs.

A digital product requires constant updates, whether it is to fix bugs or improve and enhance functionality. We monitor the app’s performance to provide data-driven insights that help you make stronger decisions for a better product.

As part of our full lifecycle app development service, we provide continued maintenance and support. You don’t have to worry about bugs post-deployment or updates as operating systems evolve. We are here to support you even after your app has been launched.

Before we even start the process of building your custom app, we sit with you to understand what you need. It’s not just passive listening, either. We offer proactive suggestions where we feel our inputs are needed. Your app is built after a lot of pre-planning, risk analysis, and proper groundwork. 

Our iterative approach to building apps means you can launch your product quickly. This allows you to create a presence in the market while we continue to add features and functionality to your digital product. Improving upon an existing app also allows you to get user feedback, which you can then use to tailor it for greater acceptance.

Clean code does not just make the product look pretty; it also helps you maintain and scale it easily. We provide well-written, well-documented code that ensures robust performance over time. It also means you are not vendor-locked. Our semantically correct, logical, and self-explanatory code can be taken to any other development agency or taken in-house at any point.

Infinum began as an engineering company almost 20 years ago, and we’ve been adding services to our repertoire. As a result, we are well-placed to manage end-to-end custom software development services. We do it all: initial strategy planning, ongoing support and maintenance, and everything in between.

Our team of 400+ specialists is made up of strategy, design, engineering, and management experts. Even among our engineers, our application developers are well-versed in various technologies, coding languages, and frameworks. No matter what combination of tech stacks you need, we can match you with professionals who have the right knowledge and skills.

As an ISO-certified company, we build secure products. First, we offer cybersecurity testing to our clients. This is for both the apps we have built for them and their own. Second, we design secure products, following all conventions and using responsible providers. Third, we learn from what we discover in client apps during testing and the conventions we follow internally to improve our app development projects.
