    Software Engineer & Security Researcher | Java & C Specialist

    I am a Software Engineer dedicated to building high-performance systems and conducting security research. My expertise lies in low-level programming and backend architecture, ensuring that software is not only functional but secure and optimized.

    What I do best:

    Systems Development: Building and refactoring robust backends using Java and C.

    Security Auditing: Identifying vulnerabilities and implementing security best practices (Bug Bounty mindset).

    Code Optimization: Analyzing bottlenecks to improve system performance and memory management.

    Technical Interfaces: Crafting functional and minimalist front-end solutions for developer tools.

    I focus on delivering clean, maintainable code for clients who prioritize security and efficiency.
