Security automation · SIEM/SOC · backend · internal tools

Most of my work starts with something people already do by hand: a route that is hard to debug, a spreadsheet that is easy to break, or an operational task nobody wants to repeat. I try to turn that into a tool that shows its plan, changes only what it was asked to change, and leaves enough evidence to check the result.

I am a 5th-year Computer Security student at BMSTU IU8 and work with OpenText/TESSA at Cherkizovo. My main languages are Python, JavaScript and SQL; day to day I also work with Linux, Windows, databases, REST APIs, logs and automation around existing systems.

Looking for junior / internship roles in SIEM/SOC, security automation or AppSec.

OpenText bulk work: hours → ~10 min · Alfa CTF 2026: #45 · 3+ years in systems / automation before my current role

OpenText Toolkit / Matrix Cleaner Started as a small Tampermonkey helper for approval matrices. It now parses requests, scopes changes, previews affected rows, blocks ambiguous cases and applies only reviewed operations. On covered bulk changes, work that used to take hours can be completed in roughly 10 minutes. JavaScript · Tampermonkey · Playwright

TESSA Matrix Studio Round-trip editor for approval matrices: export to XLSX, make bulk edits, get an exact diff, review it, then apply only if the live state still matches. JavaScript · XLSX · CI / releases	EyeGate-L Two-door access-control prototype with a camera/vision pipeline, access policy, gate state machine, authentication, React UI and hardware-facing layer for LuckFox-class edge hardware. Python · FastAPI · OpenCV · React · serial / hardware
SH4PART VPN Small self-hosted backend connecting Telegram Stars payment state to SQLite, Hiddify provisioning, subscription delivery and expiry reminders. Python · FastAPI · SQLite · Telegram Stars · Hiddify	SLA / Outlook Toolkit Windows-first support tooling: Classic Outlook / MAPI → SQLite ticket state → SLA calculation → Excel reports and deadline reminders. Python · pywin32 · SQLite · pandas · PySide6

OpenText/TESSA approval routes, matrices, signers, legal entities, categories, document types, sites and limits. A lot of the job is figuring out why a route behaved the way it did and whether the recurring part can be automated without making the process harder to inspect.

Matrix Cleaner and TESSA Matrix Studio both came directly from that work.

November 2022 — February 2026

More than three years around Windows workplaces, Microsoft 365, Intune, device policies, access, Windows Server and user support. I wrote scripts and browser helpers, automated Outlook / Excel routines, built Power Automate / Power BI reporting flows and an SLA tracker around Outlook → SQLite → Excel → reminders.
