Frequently Asked Questions (FAQs)

How to develop a web app?

  • Plan: Define goals, target audience, features, and tech stack.
  • Design: Create wireframes, UI/UX mockups, and prototypes.
  • Frontend: Build client-side with HTML/CSS/JavaScript or frameworks (e.g., React, Angular).
  • Backend: Develop server logic, databases, and APIs (e.g., Node.js, Django, Ruby on Rails).
  • Testing: Conduct unit, integration, and user acceptance testing.
  • Deploy: Launch on cloud platforms (e.g., AWS, Azure) or servers.
  • Maintain: Update features, fix bugs, and optimize performance.

Should a website be built using frameworks or pure code?

  • Frameworks (e.g., React, Vue, Django):
    • Pros: Faster development, built-in security, scalability, and community support.
    • Cons: Learning curve, potential bloat for simple sites.
  • Pure HTML/CSS/JS:
    • Pros: Full control, lightweight for static sites.
    • Cons: Slower development, manual security handling.
  • Recommendation: Use frameworks for dynamic/complex apps; pure code for simple static sites.

Should I outsource or hire in-house for web development?

Outsourcing offers cost-effectiveness for short-term projects and access to global talent, but it may come with communication barriers and less control.

On the other hand, hiring in-house provides better collaboration and long-term product ownership, though it involves higher costs (salaries, benefits) and longer recruitment times.

hybrid approach, where a core team is kept in-house while outsourcing niche tasks, can balance these trade-offs.

  • Mid-Complexity (e.g., e-commerce): 3–6 months.
  • Complex App (e.g., SaaS platform): 6+ months.
  • Factors: Scope, team size, tech stack, testing, and revisions.

How much does web app development cost?

  • Simple App$10,000–$50,000.

    • Design complexity.
    • Team location (e.g., US vs. Eastern Europe vs. Asia rates).
    • Maintenance (15–20% of initial cost/year).

How do you ensure web application security?

  • Input Validation: Sanitize user inputs to prevent SQL injection/XSS.
  • Authentication: Use OAuth, MFA, and strong password policies.
  • HTTPS: Encrypt data in transit with SSL/TLS.
  • Security Headers: Implement CSP, X-Frame-Options.
  • Regular Audits: Conduct penetration testing and code reviews.
  • Dependency Checks: Update third-party libraries; scan for vulnerabilities.
  • Backups: Automated backups and disaster recovery plans.
