I am developing a new project, the Data Security Platform, as the sole developer. I created a set of utilities in Golang. The first set is a group of microservices acting as a controller, interacting with Vault, Redis, Prometheus, Salt, ClickHouse, and the endpoints. It collects and processes information from nodes, creates the nodes (rebuilds the installation initrd in ISO images, embedding new information and Golang-based utilities), and controls the status of the nodes. The second set of utilities is embedded in the installation initrd, ensuring system compliance, fixing hardware and key file hashes, and reporting this information to the first set of utilities, which binds it to the node. Vault generates and stores credentials and the password for LUKS disk encryption. The entire installation is automated using an on-the-fly generated preseed file. After successful installation, the second set of utilities requests initialization from the first set, and Salt deploys the required configuration to the node (nodes have different roles defined during ISO creation). All utilities are written in Golang

Senior Developer. I joined as an exploit developer. Wrote exploits for attacks at the protocol level (ARP Spoofing, MAC spoofing, DHCP starvation, DNS rebinding, etc.) and web attacks (SQL Injection, PHP include, XSS, CSRF, etc.) using Python/C/C++. Later, my responsibilities expanded to include the creation of the backend for an automatic information security audit system, followed by the backend and exploits for a secure router (PHP/Swoole/Symfony). Subsequently, my responsibilities further expanded to rewriting WIFI drivers (ath9k and ath10k) for OpenWRT (debugged through kgdb serial port). Currently, I am the sole employee handling all tasks except frontend. This includes server configuration, designing and building the router infrastructure, designing and creating the infrastructure for a counter (another company project), creating documentation, and reporting.

Development Group Specialist. Developed interaction protocols for communication between payment senders and recipients (PSP and NPO, and between Agents and NPO) using PHP. Also worked on internal projects to create a server load monitoring system and automate server problem resolution (akin to Zabbix) using PHP. Enhanced the core of the payment system to record more detailed logs about payers using C++/Qt.
