SUMMARY
Infrastructure and monitoring engineer with 8 years in network and communications operations, now focused on observability and
data automation. Deployed a Prometheus, Grafana and Alertmanager monitoring stack for 10+ MikroTik devices in an isolated
production network, and built Python tools that parse, reconcile and audit operational spreadsheets. Works with SQL (SQLite,
PostgreSQL), Docker and Linux.
SKILLS
Monitoring: Prometheus, Alertmanager, Grafana, SNMP, Looker Studio (5 reports)
Data: Python (pandas, openpyxl, pathlib, CLI tools), SQL (CTEs, window functions), SQLite, PostgreSQL, Google Sheets and Apps
Script, DuckDB and PySpark (local mode, learning level)
Infrastructure: Linux (Debian/Ubuntu, systemd, cron), Docker, Git, Bash
Networking: MikroTik RouterOS (firewall, NAT, routing, VPN), Cisco (VLAN, ACL, basic OSPF)
EXPERIENCE
Government organization, defense sector, Ukraine | 2018 – Present
Senior Technician, Data Automation | Nov 2024 – Present
• Built a Python CLI (pandas, pathlib, Docker) that ingests batches of heterogeneous Excel trip records each half-month period
and reconciles fuel consumption against consumption norms and issued-fuel balances, removing manual re-entry.
• Designed and built an inventory ledger in Google Sheets and Apps Script: append-only entries locked after posting, corrections
by adjusting entries, validated input, generated transaction IDs and balances via QUERY. Used by several operators across
hundreds of recipients.
• Wrote a Python tool (openpyxl, pandas) that scans approximately 100+ spreadsheets per month for #REF! errors, formulas
overwritten by hardcoded values and SUM ranges that miss inserted rows.
• Wrote SQL (CTEs, ROW_NUMBER, running totals with window functions) on SQLite inside Python ETL scripts to aggregate
stock write-offs and fuel usage before reporting.
• Created 5 Looker Studio reports on Google Sheets data (2025) that refresh automatically after table updates.
Head of Communications Equipment Room | 2022 – Jan 2024
• Deployed and operated Cisco (Catalyst, ISR) and MikroTik network equipment: VLAN segmentation with 802.1Q trunks, port
security, inter-segment ACLs, static routing and basic OSPF; on MikroTik also firewall, NAT, VPN tunnels and link-failover
scripts. Led a crew of 4–7.
• Configured and deployed a containerized monitoring stack (Docker, Prometheus, Alertmanager, Grafana) for 10+ MikroTik
devices: SNMP exporter plus custom Python RouterOS API queries, with alerts on link failures and high CPU/RAM load. Located
a bandwidth drop caused by cyclic packet flooding from interface traffic graphs.
• Maintained virtualized Linux hosts for monitoring, database and container services.
Head of Radio-Relay Station | Feb 2024 – Oct 2024
• Ran a radio-relay communications node and led a crew of 4–7.
Head of Radio Station | 2018 – 2022
• Ran a radio communications station providing data and messaging links between sites; led a crew of 4–7.
PROJECTS
• Diploma project, solo (2025–2026): Python/Bash pipeline parsing telemetry from a simulated drone (ArduPilot SITL, MAVLink)
and tracking network KPIs (latency, jitter, packet loss) with Prometheus and Grafana dashboards; Docker, Raspberry Pi 4.
• Local data processing (academic and personal): used DuckDB and PySpark (local mode) to clean and aggregate raw
CSV/Parquet exports up to ~2 GB, preparing flat tables for loading into SQLite/PostgreSQL.
• survival-gateway-simulator (Python, github.com/MaximKulyk/survival-gateway-simulator): simulator for testing telemetry
transfer and fault tolerance in constrained networks.
