Our Web Development Services

With over 10 years of experience providing quality custom web app development services across a variety of industries, AccelOne has the expertise required to build advanced web apps to meet your unique needs.

We offer full-cycle and multi-platform web development services using the latest tools to build you a responsive, scalable and reliable custom web app that is fully aligned with your business needs. To reach the maximum possible user base we can build a solution that works seamlessly across all platforms, including Android, iOS, Windows, Linux, and all web browsers and devices.

Enterprise web apps

A web app for your business can involve project and task management systems, CRM, accounting and financial management, knowledge and learning platforms, employee monitoring, company-wide intranets, and more. We can also build web apps that connect different enterprises, for example, B2B e-commerce web platforms. AccelOne excels in powerful end-to-end enterprise solutions for even the most complex businesses, like healthcare organizations with detailed electronic health record management, dense financials, and strict security compliance demands.

Customer-facing apps

From customer service contact centers, self-service websites, online stores, fintech or crypto platforms, and social content platforms to interactive chatbots, AccelOne can build engaging custom web apps designed to deliver a stellar user experience.

Web portals

Our expert web developers can craft any web portal you need, in a way that is intuitive to navigate and pleasing to the eye. Our solutions span patient portals for healthcare organizations, e-learning portals, partner/vendor portals for business collaborations, employee portals, or customer portals for retailers. Because these portals often store user information or login details, we also make sure that they are safeguarded with the highest cybersecurity protocols.

Responsive Web App Design

Ensuring your website scales content and elements according to different screen sizes is expected and critical for continued use. Our highly experienced UX and UI designers craft web apps that are visually appealing, unique, and intuitive to use.

Mobile-friendly solutions

85% of American adults use smartphones, with approximately 47% of web traffic in the US originating from mobile devices, and 3 in 20 Americans access the internet exclusively with smartphones. For too long, mobile was a second thought, and companies scaled down less functional versions of desktop websites onto dissatisfied customers, but that approach no longer works in our smartphone-dominated world. That’s why our web application development process is centered around a responsive, mobile-first design philosophy in which the mobile site is designed from the very beginning for excellence, aesthetics and functionality, so that both your mobile and desktop users enjoy a seamless, high quality experience.

Web App Development Team Augmentation

Supplement your existing team and quickly upscale production with expert specialists drawn from our US-Nearshore talent pool, including custom web app developers, designers and project managers. With our Online Candidate viewer tool, you can choose from talent that meets your specific needs and get a better understanding of the candidate’s skills, experience, and character.

Experts in the latest technologies

AccelOne’s talent pool includes experts in the latest emerging technologies, such as virtual reality, augmented reality, machine learning, blockchain, artificial intelligence, spatial computing, the Internet of Things, and cloud computing. We use advanced web development knowledge and expertise in cutting-edge technology to craft web solutions that stand at the forefront of the current tech sector. If you need experienced developers familiar with new technologies to upgrade or future-proof your project, we’ve got you covered.

Web Application Integration

Web development solutions and integrations

Many modern IT systems rely on multiple software products communicating with each other, and interactions with third parties such as payment processors, social media platforms, and SaaS systems. Using custom APIs, we create web solutions that can integrate with a wide range of third-party systems, automating information flows and processes between different apps and services, whether they be part of your existing IT infrastructure or from other vendors.

Stable, snappy, and secure business operations

Whenever multiple systems are integrated, especially with some outside of your organization’s control, security and integrity of data being stored or transferred is paramount. Our cybersecurity experts have years of experience designing secure systems for large, complex enterprises using the latest protocols, so that your web application will not be compromised. AccelOne web app developers will also make sure that integrations and API calls are organized and prioritized in a way that keeps even a complex system running smoothly and quickly, streamlining the workflow in your organization.

Migrations and upgrades

Over time, updates and new frameworks can lead to previous integrations breaking or slowing down. Need your website or app modernized and overhauled to work with the latest tools or formats? AccelOne can conduct a full-cycle integration project to ensure good performance from your IT infrastructure well into the future.

Technology & Frameworks

Our senior technical managers have well over 100 years of combined experience in building scalable web applications in the latest frameworks for eCommerce, SaaS, APIs, CMS, social media networks, and more. The AccelOne talent pool includes experts in almost every popular programming language for web app development so that we can use the best tools for the job when it comes to achieving your goals.
