With 4+ years of experience in Cybersecurity and Python Automation, I help businesses identify, validate, and remediate security vulnerabilities across web applications, APIs, and backends. As a certified professional holding IBM QRadar and IBM Python certificates, I combine hands-on manual security testing with a strong engineering mindset. Most automated security scanners generate noise. I focus on the signal. I do not rely on scanner output alone. I manually investigate authentication, authorization, and business-logic flaws, reproduce vulnerabilities, document clear evidence, and translate findings into practical remediation steps for development teams. ## CORE EXPERTISE • **Web & API Security Testing:** OWASP-based testing, REST API security, authentication, session management, and access-control testing. • **SaaS & Multi-Tenant Security:** Reviewing tenant isolation, Row-Level Security (RLS), IDOR/BOLA, RBAC, privilege escalation, and cross-user or cross-tenant data exposure. • **Authentication & Business Logic:** Testing JWT handling, authorization controls, payment and business-logic flaws, and security-sensitive application workflows. • **Python Security & Automation:** Building custom security scripts, API testing pipelines, automated data workflows, and task-specific tooling. • **Incident & Threat Analysis:** Log analysis, threat investigation, and SIEM-oriented security analysis. ## TECHNICAL STACK Python, Burp Suite Pro, OWASP ZAP, Nuclei, Postman, cURL, REST APIs, Supabase/PostgreSQL, Linux/Ubuntu, and Webhooks/API integrations. ## MY APPROACH I prioritize precision and real-world impact. I focus on manually validated, reproducible findings with actionable engineering fixes. **Map Architecture → Test Attack Surface → Manually Validate Findings → Document Evidence → Recommend or Implement Fixes → Retest** Whether you need a pre-launch penetration test, SaaS security review, vulnerability assessment, or Python-based security automation, I focus on practical results that your team can reproduce, prioritize, and act on. Send me your application or API stack and the main security concern, and we can define the right testing scope.
