Develop thread‑safe, high‑performance applications using Java / Kotlin concurrency frameworks.

Utilize thread pooling, non‑blocking I / O, and reactive programming for efficiency.

Develop and optimize custom IDE plugins (Eclipse, IntelliJ) for performance and security.

Apply design patterns, SOLID principles, and secure SDLC practices in architecture.

Implement dependency injection, microservices, and domain‑driven design concepts.

Design and maintain on‑premises deployment solutions following security best practices.

Apply encryption, authentication, and authorization techniques (OAuth, JWT, SAML).

Ensure compliance with OWASP, NIST, and ISO 27001 standards.

Collaborate with DevOps to harden environments and ensure secure deployments.

Required Skills & Qualifications
