    FAQs

    Quali qualifiche devo cercare quando assumo uno sviluppatore JavaScript dedicato?

    When hiring a dedicated JavaScript developer, look for strong experience with core JS and modern frameworks like React, Angular, or Vue. Bonus points for clean code practices, API integration skills, and familiarity with testing tools. And of course, solid communication and problem-solving go a long way on any dev team!

    Ci sono differenze tra l'assunzione di sviluppatori JavaScript freelance e l'assunzione da parte di un'agenzia di sviluppo?

    Absolutely, there are a few key differences! Freelance JavaScript developers can be great for short-term tasks or quick fixes, but agencies typically offer vetted teams, faster staffing, consistent quality, and long-term support. It really comes down to the level of reliability, scalability, and project oversight you need.

    Quali sono i fattori da considerare per determinare il budget per l'assunzione di sviluppatori JavaScript dedicati?

    When budgeting for dedicated JavaScript developers, consider the developer’s seniority, required tech stack, project complexity, and duration. Rates can also vary based on location and engagement model. At Innowise, we keep it transparent from day one. No hidden fees, just clear pricing and support to help you plan with confidence.

    How do you handle the scalability of teams if our project grows or needs more developers?

    At Innowise, we make scaling easy. If your project grows and needs more hands on deck, we quickly provide additional vetted JavaScript developers who match your stack and workflow. Whether you need to ramp up fast or scale down later, we handle it smoothly.

    How do you address security and code quality assurance in JavaScript development?

    We take both security and code quality seriously at Innowise. Our JavaScript developers follow best practices like secure coding guidelines, code reviews, and regular static analysis. We write clean, testable code with strong version control and run unit and integration tests to catch issues early. Plus, we're ISO 27001 certified, so your data and IP are always in safe hands.
