Frequently asked questions about coding, web development, application security, and my services.
I'm a full-stack developer working primarily with JavaScript, TypeScript, React, Next.js, Node.js, Tailwind CSS, and PostgreSQL. I also implement strong security practices across every stack layer—from frontend validation to backend auth and secure deployments.
I follow OWASP Top 10 principles, use secure authentication flows, validate user input rigorously, and regularly audit code for vulnerabilities. I also set up environments like Qubes OS for secure workflows and build hands-on labs to test and improve application defenses.
Absolutely. I build scalable, performant, and secure web apps tailored to your business goals. Whether it's an MVP, full platform, or internal tool I can handle everything from planning to deployment.
Yes. I can audit your application for common vulnerabilities, recommend fixes, and implement modern security measures like HTTPS, CSP headers, secure auth, role-based access, and more.
Performance is critical. I use lazy loading, image optimization, efficient data fetching, CDN integration, and caching techniques to ensure fast load times and seamless user experience—without compromising security.
