Expert Backend Solutions

1. Concept development from initial discovery

Duration: 2-6 weeks

For an effective backend development or upgrade, it's crucial to grasp the underlying business concept, software requirements, and associated processes. At Sfinitor, our business consultants and software architects engage in detailed discussions about the software category, projected and current user base, integration needs, and suitable on-premises or cloud deployment options. Leveraging this knowledge, they outline the functional and non-functional requirements, potential risks, and constraints of the forthcoming backend system.

Sfinitor's Advice: For accurate budgeting and time estimation in our projects, a meticulous 2-3 week exploration phase yields optimal results, reducing potential costs during development. Additionally, incorporating front-end developers into the back-end conceptualization process expedites planning by leveraging their unique insights.

2. Designing Backend Architecture

Duration: 4-8 weeks

The design of the back-end architecture is the backbone of your solution. If the architecture isn’t planned out well, the entire solution fails regardless of the high quality of front-end code or neatness of back-end code. Hence, a lot of consideration needs to be put into choosing and describing the right architecture pattern. This process usually includes 5 steps:

Back-end analysis entails collaboration between software architects and users, clarifying essential and desirable features for the optimal solution, based on project restrictions.

Architects craft multiple backend solutions, categorize them based on predefined criteria, then select the optimal fit for specific project requirements.

Best practice: Sfinitor defines the following back end architecture qualities:

• Assures reliability via fault tolerance, availability, and robust security
• Scalability: Effortless expansion and simultaneous advancement of solutions
• Clean, readable code for seamless continuous deployment following automated testing ensures testability
• Maintainability: Streamlined, minimizing update efforts for maximum flexibility

3. Backend Software Development & Quality Assurance

Duration: from 2 months

Back-end development encompasses creation of server-side software, including scripts, algorithms, and APIs. This software is typically deployed in the cloud or, less frequently, on-premises systems, serving as the core functionality driving the overall solution. In parallel, quality assurance experts collaborate closely with developers, executing both manual and automated testing of delivered code to ensure optimal performance and reliability.

Optimal Approach: Sfinitor's development teams leverage various frameworks to expedite back-end development processes. Each framework type provides distinct benefits: PHP frameworks offer robust tools for web development; .NET enables creation of applications targeting any platform type; back-end JavaScript allows for full-stack development opportunities; while mature Python and Java frameworks provide the strongest security measures.

4. Establish database: Development & Setup

Duration: from 1 month

The centralized database furnishes essential data for your solution, supplying it dynamically through APIs to end clients. It may also incorporate advanced business rules for data enhancement.

Back-end development often encompasses the setup of databases and APIs within solutions for back-end projects. This includes managing data distribution and replication across various virtual machines through cloud database services, ensuring continuous data availability even when multiple machines malfunction.

Optimal Approach: Distinctive database categories include SQL and NoSQL. For straightforward web applications, web portals, and enterprise software, we prefer SQL databases at Sfinitor. NoSQL databases are advantageous for social networks, IoT, big data, and large e-commerce platforms.

5. Deploy & Integrate Systems Seamlessly

Duration: 1–3 weeks

Upon completion of the back-end software and database implementation, deployment options include both cloud-based solutions or on-premises servers. The back-end can then be seamlessly integrated with client-facing interfaces as well as third-party applications. Thorough planning for these integrations during the initial development stage of the back-end is essential to prevent unforeseen circumstances from delaying the launch of your backend solution.
