  • Introduction

    Software developers are tasked with creating, testing, and refining programs, working to the specifications the project requires. The fundamental tasks include:

    • Creating clean and efficient code that's easily understandable and usable by programmers and developers
    • Testing and deployment of programs and systems
    • Gathering and evaluating user feedback
    • Generating and implementing suggested improvements
    • Troubleshooting and upgrading existing software
    A software developer needs to be familiar with programming languages, such as Python, Java, Scala, C++, and Ruby. The job is similar to several other IT roles, but with important differences.
    • Computer programmers carry out many similar tasks, but developers need to have a more creative, big-picture view of the process.
    • Web developers focus on websites and browser-based apps, while software developers focus on programs for desktops and mobile devices.
    • Software engineers work in teams to create the tools to build apps, whereas developers put those tools to work.

  • Where can I hire software developers?

    Large-scale talent-matching websites provide tools for customizing your company profile, posting positions, searching for active candidates with the right specialties, and setting up interviews. The best sites vet their candidates and make it easy to focus on experienced tech talent. Toptal, Hired, Stack Overflow, GitHub Jobs, RemoteOK, and Arc are all good options.

  • What is the software development life cycle?

    A typical SDLC consists of seven phases:

    1. Planning (costs, timetable, team and leadership structures)
    2. Defining Requirements (needs the software can meet)
    3. Design and Prototyping (concept and modeling of look and function)
    4. Software Development (writing and documenting code)
    5. Testing (human and automated)
    6. Deployment (releasing to users)
    7. Operations and Maintenance (resolving bugs)

  • How to manage a software development team

    Set clear team and individual goals and distill management expectations so the team and the company's priorities align. Have an open-door policy and frequent one-on-one meetings with team members. Keep stakeholders abreast of needs and issues. Empower the team to make decisions and avoid micromanaging whenever possible.

  • Web Developer vs. Software Developer vs. Computer Programmer vs. Software Engineer: which one do I need?

    Websites and browser apps need web developers. People who can engage with every phase of the software development life cycle are software developers. Computer programmers focus on the third through fifth phases of the SDLC. Designing tools for producing code requires software engineers.

  • What is Agile Scrum methodology for software development?

    You can use a sprint-based Agile Scrum methodology for fast results. "Agile" refers to a user-focused mindset of embracing change, motivating individuals, and early and continuous delivery. "Scrum" refers to short two-week sprints that allow teams to focus on pieces of a complex project.

  • How do I know if I need an in-house software developer or a freelance software developer?

    Freelancers provide the flexibility to hire people with distinct skills for different projects, and you can save money by hiring only for specific times. Communication with an in-house team is often faster, and they're more likely to understand your business needs. The better solution will depend on your situation
