Unit tested with Google Tests C++ Framework and managed a team of twelve engineers with Scrum Agile. - Redesigned a Django web analytics dashboard and engineered an automatic examination structure for malware and additional hazards impacting disparate target systems, all whilst version-controlling codes through Gitlab- Innovated an SDN crypto-agile MTD architecture with post-quantum cryptography in Python and REST with Flask, increasing security by frequently changing encryption keys at unpredictable intervals as fast as three minutes as part of a Research prototype that sold for $5 million. - Introduced new electronic warfare capabilities by engineering a mesh networking prototype utilizing LoRa radios and LoRaWAN networks with open-source software like Meshtastic, producing custom C++ modules- Managed a research team in an innovative investigation of vehicle exploitations involving telematics, examining vehicular radiations and emissions, and handling finances, scope, scheduling, and delivery while version controlling codes using Gitlab. This work was involved in an RFP for a multi-million dollar contract that brought in new customer business.- Authored three cybersecurity collaboration proposals between Leidos and George Mason University Computer Science, focusing on Chromium OS, MTDN and S.T.I.X., and established a CAPSTONE partnership with the university.

- Engineered an analytical engine that ingests, normalizes, and de-dupes CTIs for OSINT Threat feeds correlated with Vulnerability reports displayed on geographic threat map technologies,  integrating them with MITRE TAXII server STIX CTI. Implemented the back-end infrastructure using MongoDB and NodeJS. - Published custom APIs in Python to support the MITRE STIX framework.-Ivan was a member on the OASIS Technical Committee’s STIX and TAXII groups-

- Launched a user sign-up web form to automate the manual process of user account creation, reducing onboarding time for new users from a day to a few hours: leveraged MongoDB, ExpressJS, NodeJS, and front-end frameworks such as Materialize.css. Ivan then revamped the web form to use Python flask with Bootstrap as the front end.

- Devised a script in Python that automates the end-to-end provisioning process for phones, turning off-the-shelf devices into secure Customer-compliant devices and cutting down time by 50% from a manual process. - Produced a Python module that implemented Samsung’s EMM API calls into Python to place users into pre and post-provisioning organization units automatically.- Orchestrated automatic control scripts in BASH are to be automatically applied to a Linux machine using device managers.
