Frequently Asked Questions
I offer comprehensive security testing services including vulnerability assessments, penetration testing, code reviews, and API security audits. My approach covers OWASP Top 10 vulnerabilities like XSS, SQL injection, and authentication flaws, as well as business logic flaws often missed by automated scanners. Each assessment includes detailed documentation of findings, risk levels, exploitation proof-of-concepts, and actionable remediation steps to help secure your digital assets.
Project timelines vary based on complexity and scope, but typically range from 2-3 weeks for simple landing pages to 2-3 months for complex applications. After our initial consultation, I'll provide a detailed timeline with key milestones. Each project includes planning, design, development, testing, and revision phases. I maintain transparent communication throughout, providing regular updates and adhering strictly to agreed deadlines to ensure timely delivery without compromising quality.
Yes, I offer remediation services as part of my security packages. After completing the assessment, I can work directly with your development team to implement fixes or handle the remediation myself. This includes detailed guidance for each vulnerability, code examples, and best practices to prevent similar issues in the future. For critical findings, I provide emergency patches and verification testing after fixes are applied to ensure the vulnerabilities have been properly addressed.
All projects include a 30-day post-launch support period for bug fixes and minor adjustments at no extra cost. For ongoing support, I offer flexible maintenance packages with options for security monitoring, regular updates, performance optimization, and priority technical support. These packages can be customized to your specific needs, whether you require basic maintenance or comprehensive ongoing development. This ensures your website or application continues to perform optimally and remains secure against emerging threats.
I specialize in modern web technologies including React, Angular, Vue.js, Node.js, PHP/Laravel, and Python/Django for development projects. For e-commerce, I work with platforms like WooCommerce, Shopify, and custom solutions. My security expertise covers web applications, APIs, mobile applications (iOS/Android), cloud infrastructures (AWS/Azure), and content management systems like WordPress and Drupal. This versatility allows me to select the most appropriate technology stack for your specific requirements and business goals.
