      Web Design Review from Patrice Archer

      They developed a SaaS web platform with smart scheduling and automation tools for us at and built the platform's front- and backend and integrated a custom analytics dashboard and calendar integrations. But to be honest what impressed us most was how deeply they engaged with our vision. They didn't just write code they challenged assumptions, proposed better workflows, and contributed as if they were part of our internal product team. Their ability to think strategically and focus on user experience made them feel more like tech partners than a typical outsourced vendor.

      Igor Caleta-Car's Review Sourced from Google

      I worked at Decode for about a year, and during that time I had the chance to meet many wonderful colleagues who helped me grow professionally and learn new skills. Because of the nature of my role, I also had the chance to collaborate with clients across Europe, the USA, and the Middle East, and even visit some of them in person. The team I worked with was everything you could hope for - driven, proactive, and always willing to jump in and help. The development teams I was part of were well-balanced in both skills and personalities, led by highly experienced engineers who lead by example. Beyond the projects themselves, the company culture stands out. People are friendly, and the leadership is focused on sustainable growth while supporting employees development. Decode isn’t afraid to promote talent and encourage people to step outside their comfort zones in order to grow. The office is also in one of the best business neighborhoods in Croatia, with plenty of variety for employees nearby. Overall, I highly recommend Decode as a great place to work!

Their modern design approach aligns well with our vision, and they show a real commitment to delivering a strong final product. What we particularly appreciate is their willingness to engage and adapt as the project evolves. While some aspects require additional clarification along the way, they are always receptive to feedback and ready to adjust accordingly. The overall working atmosphere is positive and professional, making them a great partner to work with. Looking forward to the second half of our project!

Cloud Application Development Company Hiring Guide

What is a cloud application development company?

A cloud application development company is a specialized company that creates software solutions hosted on remote servers, also known as the cloud, rather than on local, on-premise servers. Its core focus is enabling users to access apps via the Internet, using a web browser or a mobile app, regardless of their location. Using cloud computing platforms like Amazon Web Services (AWS), Microsoft Azure, and the Google Cloud Platform, this specialized agency helps businesses elevate user experiences, increase service accessibility, and propel business growth.

Generally, there are four types of cloud computing:

  1. Private cloud
    A cloud computing model dedicated to a single organization that can be accessed only by entity-authorized users, making it ideal for businesses requiring strict security measures. It can be hosted on-premises or by a third-party provider.
  2. Public cloud
    Across this computing model, services and infrastructure are offered by third-party vendors over the Internet. Although infrastructure is shared among organizations, only authorized users of each organization can access specific data and services.
  3. Hybrid cloud
    This model combines private and public cloud environments, allowing users to move data and applications between the two while still enabling access to authorized users only.
  4. Multi-cloud
    A cloud computing model wherein an organization uses cloud services from multiple providers (e.g., AWS, Azure, Google Cloud) to meet versatile business needs. This approach can improve flexibility, redundancy, or performance while allowing organizations to avoid vendor lock-in.

The cloud computing industry is on a rapid rise, recording $1.6 trillion in revenue in 2023, with the Americas as the biggest regional spender. In terms of segment, software-as-a-service (SaaS) holds the largest market share, estimated at $247 billion in 2024. As for applications, roughly 65% of organizations cited custom applications as the main reason for using cloud-native platforms.

With cloud applications in high demand, it is easy to understand why businesses need cloud application development services. Beyond amplifying apps’ agility and accessibility, these services address critical technical requirements and operational complexities, helping organizations overcome the following challenges:

  • Difficulty integrating legacy systems with modern cloud platforms, causing operational inefficiencies and delays in data migration
  • Lack of off-the-shelf cloud applications that meet the business’s requirements
  • Outdated systems that are slow, glitching, and difficult to use
  • Disparate internal systems that result in zero real-time data visibility and inaccurate insights that may lead to income loss
  • Poor user experience and high user churn rate
  • Limited access to real-time support and troubleshooting, which prolongs downtime and negatively impacts service continuity
  • Encountering vendor lock-in risks, which imposes difficulties to switch providers or adopt multi-cloud strategies without significant cost or disruption
  • Difficulty staying up to date with the latest cloud computing regulations, best practices, and technological advancements

Success story

To highlight the importance of cloud application development services in addressing these significant challenges, we've selected the following case study from ELEKS:

  • Challenge: Global oil and gas enterprise TechnipFMC wanted to revamp its centralized business system, FuelFACS, and shift it from an on-premise solution to a cloud-based one.
  • Solution: The ELEKS team began with a two-week client visit to refine the project vision and gather essential system artifacts. The company reverse-engineered TechnipFMC’s centralized business system and migrated FuelFACS to Azure, implementing it as a single-page web app optimized for the cloud. The Azure migration resolved performance issues, enabled centralized updates, and introduced Agile practices that enhanced Technip’s customer engagement and accelerated time to market.
  • Results: Through ELEKS’ expertise, FuelFACS’ operations were scaled to meet user demand, providing 24/7 availability and minimizing downtime. The client realized substantial IT support savings by eliminating the costs of on-premise hosting, patching, and product updates.

  • Challenge: A hunger relief solution firm was experiencing delayed logistical operations and inefficient performances across its chain due to an outdated web admin dashboard.
  • Solution: Trinesis addressed the client’s mobile app challenges by focusing on three core pillars. First, it migrated the entire system to Microsoft Azure to facilitate quick data access, advanced monitoring dashboards, and efficient billings. Next, it leveraged React Native to streamline workflows, improve delivery tracking algorithms, and enable real-time monitoring and reporting. Lastly, the team used .NET/C# to create an advanced admin dashboard and Angular to improve backend APIs.
  • Results: The upgraded mobile app provided the client with real-time reporting and tracking capabilities, increasing its operational efficiency and transparency.
