Core Applications in Cybersecurity

Enterprise Web Apps

Building and securing large-scale web applications and APIs using frameworks like Spring Security.

Android Security

Performing static and dynamic analysis of Android apps, reverse engineering, and mobile malware analysis.

Identity & Access Mgmt.

Developing and integrating with IAM solutions, including SSO, OAuth2, and SAML-based systems.

Static Analysis (SAST)

Creating custom rules and tools for static code analysis to find security vulnerabilities in Java codebases.

Cryptography

Implementing secure cryptographic operations using the Java Cryptography Architecture (JCA/JCE).

Security Middleware

Building security components for large data processing platforms like Kafka, Elasticsearch, and other SIEM tools.
