Background and Journey
Software Developer with Cybersecurity and Testing Expertise, specializing in developing, testing, and securing software applications with cryptography, network security, and resilient system design.
Proficient in Python for building and rigorously testing production-ready tools that address vulnerabilities and enforce data protection standards. Currently pursuing B.Tech in CSE (IoT, Cybersecurity including Blockchain Technology) at Vasireddy Venkatadri Institute of Technology with 8.54 CGPA.
Eager to engineer robust, thoroughly tested applications maintaining system integrity through secure coding, software testing methodologies, and threat mitigation strategies.
My technical arsenal across development and security
A timeline of my professional growth
Academic background and achievements
Production-ready security and development projects
Production-grade network firewall with Smart Mode (auto-block unknown devices) and Strict Mode (whitelist-only). Engineered automated rule management using raw socket packet inspection and TCP/UDP/ICMP protocol filtering—achieving zero manual intervention.
View on GitHubMultithreaded TCP/UDP scanner covering full 1-65535 port ranges with optimized socket programming. Implemented service banner grabbing and vulnerability detection (FTP, SSH, HTTP) with version identification for secure network assessments.
View on GitHubMultithreaded ARP spoofer using Scapy for continuous network scanning and real-time cache manipulation, demonstrating MITM attack simulation. Developed automated device detection for controlled penetration testing and network security research.
View on GitHubDeveloped and tested Python TLS Scanner assessing cryptographic agility across 4+ databases, SMTP/IMAP/POP3 mail servers, and web servers. Engineered clean, modular plug-and-play components using 3000+ cipher database for NIST PQC compliance.
