INFORMATION NETWORK SECURITY AGENCY, Addis Ababa, Ethiopia 2007-2015

Government organization specializing in information security. Cryptographic Algorithm Design / Development Team Leader Led design and implementation of cryptographic algorithm using C programming language in Ubuntu platform. Generated elliptic curve parameters (a, b, p, G, n) using GNU Multi-Precision Library for their mathematical representation. Coordinated team of developers and established effective working environment. Strengthened security requirements for problem domain given by company.

Responsibilities

●Understand, analyze, design, and develop web based systems and associated modules using Java, development frameworks and relational databases.

●Perform software coding, testing, debugging for on-line processes in accordance with industry best practices and specific internal procedures and standards.

●Contribute to task identification, work effort estimates, and work schedules for development and maintenance activities.

●Implement new features for existing application and assist in building new applications based on customer specification, involvement in the entire software development life cycle process.

●Involved in software development, implementation, testing and production support.

●Involved in the development of security for memory constrained devices using C, Java, SQLite.

●Worked as SCRUM master to lead project development using Agile SCRUM methodology.

●Mentor peers to make them understand the requirement, technical support and Co-ordinate with the release management team to ensure that the proper process is followed during the release.

●Application Performance enhancements and insures the security requirement had been implemented properly.

●Created documents as needed for Software development life cycle and knowledge sharing for team members.

●Worked with QA Team for Quality Assurance and Test case automation of the Application.

●Led design and implementation of cryptographic algorithm using C and Java.

●Coordinated team of developers and established effective working environment.

●Strengthened security requirements for problem domain given by the company.

●Developed algorithm to streamline web-based medical consultancy by establishing medical case for patients and reporting information to doctor.

●Performed analysis on Microsoft Word 2003 files object format to initiate security break of encrypted files. Led successful break of DES algorithm, Microsoft Word 2003 RC4 algorithm and PDF 1.4 encrypted file using CrackPDF as open source. Defined integrity of cryptographic component on all files and identified application vulnerability through file integration.

●Designed tracking system using geo-spatial information system and war game. Generated information from MySQL database and provided data in ArcMap using ArcGIS system.

●Developed algorithm to represent information and draw pointer on displayed map. Elliptic curve-based cryptographic solution as opposed to RSA-based solution for Radio communication and any small devices by achieving same security strength but avoiding memory constraints of RSA solutions for these.

●Insure the security of different applications using standard encryption, decryption, and hashing, key management, certificate management, and signatures.
