A scientific, customer-centric framework for systematically improving conversion rates on websites and landing pages. This methodology guides users through funnel mapping, identifying core visitor objections, and conducting evidence-based A/B testing. It is essential for auditing underperforming funnels, optimizing checkout flows, and transforming general marketing hypotheses into measurable, statistically significant improvements.

A comprehensive set of architectural patterns for building robust and maintainable HTTP servers using Kotlin Coroutines and the Ktor framework. It covers essential topics including REST routing DSL, plugin configuration (Authentication, CORS, StatusPages), Dependency Injection (Koin), serialization, WebSockets, and integration testing using testApplication.

A comprehensive guide to using k6 for robust performance and load testing across APIs, WebSockets, and browser scenarios. Learn to write realistic load simulations (smoke, load, stress, soak), analyze performance metrics, set SLAs, and integrate testing into CI/CD pipelines to ensure system reliability before deployment.

AWT provides AI coding tools with the ability to perform sophisticated End-to-End (E2E) web testing using a real browser. It accepts declarative YAML scenarios and executes them via Playwright. Key features include visual matching (OpenCV + OCR) instead of relying on fragile DOM selectors, automatic platform detection (React, Vue, etc.), and structured failure diagnosis for improved AI coding workflows.

This guide details advanced techniques for authorized security assessments, focusing on forced browsing. It helps testers discover hidden administrative pages, unprotected APIs, and configuration files by systematically enumerating URLs and challenging application access control mechanisms. Techniques involve using tools like ffuf and Gobuster for comprehensive path and directory discovery.

This skill guides the detection and exploitation of JavaScript prototype pollution vulnerabilities. It covers both client-side (DOM XSS) and server-side (RCE, Auth Bypass) attacks by injecting properties into Object.prototype using keys like `__proto__`. Use this when assessing APIs that deep-merge or clone user-controlled JSON data, or for general web application security testing.

This guide details the comprehensive methodology for detecting and exploiting Server-Side Template Injection (SSTI) vulnerabilities across multiple popular template engines, including Jinja2, Twig, and Freemarker. It provides step-by-step workflows, covering payload detection using basic arithmetic expressions, engine identification, and executing advanced Remote Code Execution (RCE) payloads for penetration testing purposes.

This skill details techniques for exploiting PHP's type juggling vulnerabilities, primarily caused by loose (==) comparison operators. It demonstrates how attackers can bypass authentication mechanisms, defeat magic hash function verifications, and manipulate application logic through controlled type coercion when testing web applications. Ideal for authorized security penetration testing.

This comprehensive guide outlines techniques for authorized penetration testing of real-time web applications using WebSocket connections. It covers discovering various WebSocket endpoints, testing for authentication bypass, identifying Cross-Site WebSocket Hijacking (CSWSH) vulnerabilities, and assessing message handling for injection flaws (SQLi, XSS). Essential for securing chat, trading, and live notification platforms.

This guide details how to integrate OWASP ZAP (Zed Attack Proxy) into CI/CD pipelines (GitHub Actions/GitLab) for comprehensive Dynamic Application Security Testing (DAST). It covers configuring baseline, full, and API scans to identify common vulnerabilities like XSS, SQLi, and CSRF in running web applications and REST/GraphQL APIs, ensuring security quality gates in the development lifecycle.

A comprehensive guide detailing techniques for detecting and exploiting Blind Server-Side Request Forgery (SSRF). It uses advanced out-of-band (OOB) techniques, such as Burp Collaborator and timing analysis, to interact with internal services, scan private IP ranges, and extract cloud metadata (AWS, GCP, Azure) even when the application does not reflect the server response directly. Essential for web application penetration testing.

This skill guides authorized security professionals through testing web applications for clickjacking vulnerabilities. It involves checking frame embedding controls (like X-Frame-Options and CSP) and crafting complex proof-of-concept overlays to see if users can be tricked into performing unintended sensitive actions, such as deleting accounts or transferring funds.
