Some of my experiences here include but is not limited to:- Data Import/Export: Provided a solution for secure, offline data exchange between multiple master/slave devices. - Package Cryptography: Provided tools and multiple APIs to sign, verify, encrypt, anddecrypt packages. Used Python’s cryptography library to auto generate keys, accept passwords and perform key elongation. Supported AES-GCM, AES-CBC and Camellia encryption standards.- Remote Device Health Monitoring: Used ansible’s internal APIs to gather data about resource usage and system health for the hosts and multiple docker containers running on each host. Provided a caching mechanism to reduce required time for gathering data. Used Redis' internal API instead of the CLI to increase flexibility. - Consumer/Producer: Wrote a custom producer using Redis arrays as the caching backend. The consumer provided retry mechanism and reporting tools and an API to control its behavior. Threading and multiprocessing were used in a non-blocking way to handle IO and CPU bound processes and increase utilization for thousands of devices. - System Maintenance & Features: Added features to existing microservices. Implemented changes for compatibility with newly added features. Performed unit, functional, and integration testing. Show less

Worked on a national project to develop an online SSL/TLS checker to analyze and score the security of online services and websites. Available at sslcheck.cert.ir

Managed, deployed and supported a large network of windows and *nix based servers, providing service to hundreds of thousands of online websites and services. My job also included dabbling with already deployed services and legacy code to improve and maintain existing infrastructure and automate repeated tasks.
