FAQ
What technologies do you use for web development?
I mainly work with Vue.js or React.js for the frontend, and Flask or FastAPI for the backend. I also use HTML, CSS, JavaScript, and Git for version control. For database, I often use PostgreSQL together with others and some NoSQL ones.
Can you integrate my web app with an existing API or database?
Yes, I can integrate REST APIs, connect to SQL or NoSQL databases, and customize the backend to fit your existing infrastructure.
Will my website be mobile-friendly?
Absolutely! All websites I deliver are fully responsive and optimized for desktop, tablet, and mobile devices.
Do you offer hosting or deployment services?
Yes, hosting setup and deployment are included.
Can you add e-commerce functionality to my site?
Yes, I can integrate secure payment gateways, set up product listings, and add shopping cart functionality.
What do you need from me to get started?
I’ll need a short project brief, any content you want included (text/images), and details about your preferred style or reference websites.
How fast can the application be done and what is your availability?
I am available for at least 20 hours a week, however this can be changed based on client needs or budget.
How do you secure web applications and make them fast?
I follow security best practices such as input validation, authentication & authorization setup, HTTPS configuration, and protection against common vulnerabilities (SQL injection, XSS, CSRF). For speed, I optimize frontend code, enable caching, compress assets, and use efficient database queries.
