What I'm looking for

I’m seeking an Application Security Engineer, Product Security, or Web VAPT role where I can test web applications and APIs, fix vulnerabilities in code, and help secure products.

At Allied Aviation India Pvt. Ltd., I found and fixed XSS and insecure API endpoint issues in a digital banking platform, using Burp Suite and OWASP ZAP. I also implemented security headers and JWT, OAuth 2.0, and RBAC controls.

On the banking platform, I improved API performance by 40% through SQL query optimization, indexing, and Redis caching, and worked with QA and DevOps on testing and vulnerability remediation before releases.

At NielsenIQ India Pvt. Ltd., I tested and fixed OWASP Top 10 issues across a financial data and analytics platform. I also improved real-time reporting retrieval speed by 25% through query optimization and Redis caching.

My software development work includes building a WebRTC telehealth platform at One Health Assist and secure payment integrations for food delivery and e-commerce projects. I’m currently building personal projects and completing cybersecurity and AI certifications.
