Gaijin, SRE Engineer, Apr 2025 - $(date)

• Investigated and resolved the Dimensione ISP clients' inability to use Gaijin services.
• Fixed a long-standing firewall deployment bug, which would previously lead to (unnoticable by us!) inability for users to connect.
• Fixed a long standing issue in the Terragrunt repo, which had previously made it impossible for many other engineers to work on AWS related tasks.
• When several production hosts at the Amsterdam datacentre shut down due to overheating, coordinated the internal mitigation efforts. Provided the necessary information to the datacentre engineers for the fastest possible resolution.
• On multiple occasions was the first to notice a production site being down. Every time, coordinated the efforts to fix the issue in a timely manner.

Inango, System Administrator, 2024 - 2025

• During the otherwise rushed shutdown of the company's Kazakstan office, coordinated the migration of employee workstations to other locations. Ensured that the affected employees could actually continue their duties despite the circumstances.
• Fixed the previously non-functional attendance report (time tracking) script.
• Fixed networking problems in developers' test setup, resolving the disrupted development process.
• Relieved the burden from the admin team by fixing software that now allows the HR department to disable the departed employees in a simple and secure manner.
• Installed workstations for new employees, who would otherwise not have been able to perform their duties.
• Identified and fixed network outages that would have disrupted the normal development process.
• Provided VPN connection scripts, significantly decreasing the time it takes for the new hires to start working.
• Identified and fixed old and incorrect information on the wiki, significantly lowering the chance of network misconfiguration in the future.

InfoTeCS, Researcher, 2022 - 2024

• Developed a firewall module, that most traffic passes through; roughly x2 worst case scenario speed increase.
• Assisted partners at Intel with remote debugging. New firmware was ported to old hardware as a result.
• Coordinated secure boot research for an ARM platform between several departments. That used to be the main issue with certification.
• Made and performed benchmarks for future use in hardware procurement. That includes rack servers, single-board computers and microcontrollers, AMD64, ARM and RISC-V based.
• Documented the I2C bus on an ARM microcontroller, allowing for company's software to be ported onto cheaper boards.
• Documented all of the above, wrote presentations and articles for the internal newsletter, etc. Presented the R&D department work in general, and mine in particular, to the stakeholders.
• Coached the other reseoarchers and testers (all of the latter non-programmers) on correct usage of C language and Unix utilities. Helped find solutions to many of the department's hardest problems.

Eneik

• Streamlined application deployment process by creating a developer- and administrator-friendly environment.
• Successfully the entire infrastructure, ensuring present availability of services.
• Established an actual backup procedure for said infrastructure, ensuring future availability of services.
• On several occasions, used said backups to restore client's sites to working order, and prevent future outages. Particularly related to an infected Wordpress site, and database usage errors.
• Configured LAN at the coworking. Prior to that ethernet connection was not available for most clients, and Wi-Fi was the only option.
• Developed and deployed a website and a telegram bot for the local cafe Rock Buffet, allowing the owner to have a sustainable business model. (And the owner of Eneik to order pizza whenever he wishes. :)
