Ukraine, Poland, and Romania are the countries where you are most likely to find experienced and skilled offshore .NET developers. But what skills make a successful .NET developer? Let’s find out.
Skills that experienced offshore .NET developers have
ASP. NET, ASP.NET Core framework
ASP. NET and ASP.NET Core frameworks are crucial for building web applications. These frameworks offer benefits such as a unified story for building web UI and web APIs, the ability to run on Windows, macOS, and Linux, a lightweight, high-performance HTTP request pipeline, and many others. Basically, they make the development process more efficient.
Thus, you need offshore ASP.NET developers for successful project delivery.
ASP.NET model view controller (MVC) pattern
With the help of the ASP.NET MVC pattern, .NET developers can make fast and secure web applications. The pattern allows offshore ASP.NET developers to decouple user interface (view), data (model), and application logic (controller). So, it helps to achieve separation of concerns, which gives the opportunity for test-driven development. Thus the development process gets easier.
Knowledge of databases
Data storage is critical when it comes to web application development. Thus, a skilled offshore .NET developer should know how to effectively work with databases. Your offshore .NET developers should know both relational and non-relational databases.
A relational database is structured and has relationships (dependencies) with one another. For instance, a database for a school that contains separate tables for students and for class offerings.
A non-relational database is document-oriented, so all information is stored in more of a list order. For example, a database in which each customer has their own document that contains information, including name, address, order history, and credit card information. Despite different formats, all this data can be stored in the same document.
An experienced offshore .NET developer should know the pros and cons of three main cloud vendors: AWS, Google Cloud, and Azure and be able to tell which cloud has the best services for solving a particular task. Azure expertise is of utmost importance when it comes to .NET development, as it is also a Microsoft product, thus it is most frequently used with the .NET framework.
Also, your offshore .NET developers should have experience with cloud migration, as businesses frequently need it to achieve flexibility, scalability, automation, ease of collaboration, etc.
React and/or Angular framework
When it comes to full-stack development, your offshore .NET developers should have experience working with front-end frameworks, such as React and Angular.
Also, certifications are of utmost importance when it comes to .NET development. There are four major certifications that distinguish a skilled offshore .NET developer. Let’s view them in more detail.
Required certifications of skilled offshore .NET developers
Microsoft Azure Architect Technologies
This certification measures the ability to implement and monitor an Azure infrastructure. Also, it shows a developer’s competence in implementing management and security solutions, solutions for apps, as well as implementing and managing data platforms.
Microsoft Azure Architect Design
This exam assesses .NET developers’ skills with design monitoring, design identity and security, design data storage, design business continuity, and design infrastructure.
Microsoft Azure Fundamentals
Microsoft Azure Fundamentals exam covers cloud concepts. They are, for instance, core Azure services, core solutions, and management tools on Azure, general security and network security features, identity, governance, privacy, and compliance features, as well as Azure cost management and Service Level Agreements.
Why choose .NET over other technologies?
Microsoft promotes .NET, making the technology more efficient. .NET boasts a considerable community of people interested in updates and framework development. There are five major benefits of .NET over other frameworks and languages. Let’s view them in more detail.
The .NET framework is language-neutral, so offshore dot net developers can reuse the code multiple times to improve the effectiveness of the development process.
.NET Core is cross-platform which means that it is compatible with Windows, OS X, and Linux. As a result, software developers can build cross-platform applications, and port the already developed applications across different platforms.
Easy for cloud development
Microsoft works a lot on the improvement of its cloud programming infrastructure – Azure Cloud. So, this cloud fits for building fast and scalable applications.
What’s more, .NET is designed to be built into Docker containers, which makes deploying applications to the cloud in a lightweight and effective way possible.
The .NET framework provides various security practices to keep the .NET-based solution protected. For instance, the framework has built-in Windows authentication and cryptography classes.
Variety of tools
Due to the wide usage of the .NET framework, many tools that make work more efficient occurred. For example, Entity framework makes working with databases easier, Blazor allows writing both front-end and back-end using C#, and many others.
What’s more, Microsoft provides support and integration with many services, including Biztalk services, different kinds of CRM, etc.
Businesses that benefited from hiring offshore .NET developers
Lebara is one of Europe’s fastest-growing mobile virtual network operators (MVNO) with millions of active customers, employing over 62 nationalities worldwide in six countries. N-iX has been working with Lebara since December 2014, having built a development center that consolidates broad expertise — software development, quality assurance, business intelligence development and operations, application support, database administration, infrastructure support — everything in one place.
What concerns software development, Lebara needed a team of specialists to perform a wide range of solutions.
First of all, we migrated from on-premises WCF and BizTalk to Azure. Our specialists developed a single master data system for offline and online communication channels that enables omnichannel. Omnichannel is a single backend for all the channels of communication with Lebara customers: website, mobile app, SMS, USSD (unstructured supplementary service data), and customer service.
Customers can buy, register or activate the SIM, buy and change plans (data, bundles SMS), top-up or configure the auto top-up, check the balance, access the online support to receive the answers to the most frequently asked questions. It’s a set of 80+ microservices that encapsulate the business logic and integrations with payment providers, OCS, MNO, and regulators.
The next phase of our cooperation was the migration from Azure Service Fabric to Azure Kubernetes Services, which also involved:
- single platform for logging (was different in several places: Azure Storage account, files in OS, events in ServiceFabric. Now — Azure Monitor with Log analytics)
- migration from Windows to Linux
- migration from ASP.NET Web API 2 to .NET Core
- migration of Cloud Services, Logic Apps, and Functions to Kubernetes
- migration from Management API to Kong (cloud-agnostic solution)
- applications and infrastructure monitoring
- implementation of the Docker support
Code Worldwide is a digital transformation business that helps clients invent a new future for their marketing through technology and data. The client engaged N-iX to support the system, set up effective communication between services, and ensure their stability.
Our team is using DDD, CQRS approaches. Currently, there are over 200 microservices created in .NET 4.7 and around 10 microservices in .NET Core. Together with the client, the N-iX team developed an API with ASP.NET WebAPI. We use a set of tools (like Swagger) to follow the Open API 3.0 specifications.
Solution architecture is complex and flexible. It uses event sourcing as the main way to store and process application data. The N-iX team improved system stability and issue resolution time by introducing Log4Net logging with Azure App Insights statistics tracking. It allowed us to decrease the amount of work needed for platform stabilization by 60 percent per release.
Some not tenant-specific parts of the application are implemented on Serverless using .NET Core 3.1 and AWS Lambda. Our team was the first one to create serverless components in the platform, creating the full flow of development and CI/CD setup.
As a result of the cooperation, the client achieved:
- decreased the time to market by 60%
- the time for setting up a new tenant and its testing was reduced from two weeks to 3-4 days as a result of improved First Time Quality
- improved time to market via CI/CD process enhancements
RateSetter is a leading peer-to-peer lending company in the UK and Australia, offering services to thousands of active customers, and has matched more than £3,6 bn. RateSetter addressed N-iX at the point when they already had a well-established business model and over 250,000 active customers.
The main challenge of the project was to produce new features during migration to microservices.
As a starting point for migration, our team took a new project for the borrower journey that includes the creation of a new UI and logic update that maintains the user application. During which we designed the concept of future microservices architecture. Also, to avoid huge data migration, we decided to use proxy services at the beginning to access the data. In the scope of this project, the first 10 services were created. Additionally, the basic template for the service and migration process was introduced to the whole development team.
Our specialists migrated from classic .NET Framework 4.7 to Service Fabric in regards to PaaS, which is using .NET Core. Thanks to the new architecture, all the services can be deployed and updated independently, which gives more flexibility. Now there are over 70 microservices.
