Work Experience

Security Software Engineer

2017 - 2021

Bitdefender

Developed core components for the macOS antivirus product: Network scanning, file scanning, malware protection using C++ and Python.
Researched new technologies and implemented proof-of-concepts presented to upper management.
Participated in internal penetration testing, researching, exploiting, and providing guidance in fixing security vulnerabilities. The aim of this project was to increase the overall security of the infrastructure.
Optimized the product by profiling it in multiple tests with impressive results. I reduced the scanning time by 60% and the overall CPU usage by more than 30%.

Experience

ELF Reconstruction

This project aimed to reconstruct an entire ELF file that was given any core dump (ARM, MIPS, x86). It can be used during post-incident analysis and forensics to rebuild the binary process from a memory dump.

Food Ordering App

A iOS Swift app where restaurants can sign-up and use as an ordering system. I was the iOS developer working closely with the back-end team to design and secure a strong API.

Distributed Crawler

A C++ and Python-based application for a client needed to crawl large amounts of data and filter the results. I used technologies such as Scrapy for crawling, then distributed filtering and processing with C++ in Dockers. As a design pattern, I used Map-Reduce.
