Professional Experience

SoftServer - DevOps Engineer
2021 - Present / Ukraine

Infrastructure Automation & IaC

• Deployed osquery to 1000+ servers via Ansible using Python/Jinja2 lter, boosting audit
readiness
• Rewrote legacy Ansible playbooks for Con uence (Java, MySQL replication), cutting upgrade
time by 90%

Observability Engineering & Monitoring

• Built full-stack monitoring for osquery using Prometheus, Kibana with alerts on uptime, log
delivery, and DNS health
• Created Kibana dashboards for tra c, error rates (4xx/5xx), response times, and top
endpoints/errors
• Migrated Cisco UCS monitoring (In uxDB -> Prometheus) (7 Grafana dashboards, In uxQL ->
PromQL); rewrote Python collector for 1m resolution
• Created Grafana dashboards for VPN tra c (global) and alerts for missing network device
metrics
• Enabled storage monitoring with Telegraf + Python; back lled 3 months of data to In uxDB
• Wrote 10+ Python monitoring scripts for CIMC, license expiration, ephemeral ports, Firepower,
and 24h disk growth (>15%)
• Implemented Prometheus-based monitoring for open les, somaxconn, and Windows tasks
(via PowerShell)
• Resolved visibility on 50% appliances by xing Telegraf gaps
• Resolved year-long Cortex misrouting issue, restoring cross-DC alerting

High Availability & Reliability:

• Implemented zero-downtime volume expansion for DRBD-backed HA MySQL cluster
• Automated Con uence deployment and resolved critical migration issues with Atlassian
support in staging
• Fixed unmount issues in HA setup by adjusting Pacemaker to stop MySQL exporter before
shutdown

 • Contributed to Jira HA: tested DRBD failover, wrote DR runbooks, validated rollback plans,
supported 4-day DC hardware move

Modernization & Optimization

• Replaced deprecated Webex-Jira integration with Groovy-based noti cations, restoring
alerting to 20+ projects
• Migrated 90+ JQL reports to SQL, preserving SLA and incident KPI tracking
• Decommissioned 20+ unused NFS shares during DC migration, reducing storage overhead
• Automated Icinga host onboarding from CMDB, accelerating setup for 200+ hosts
• Built Python script to analyze 1000+ Jira security tickets, improving InfoSec triage
• Standardized 15+ runbooks, cutting incident resolution time by ~ 25%
• Built GitOps-style Jenkins pipeline for Prometheus alert rules: triggered by Git MR, validates
con g (promtool, yamlint), and auto-merges to master on success

Jira Data Center Migration & Modernization Project (Lead Engineer)

• Led complex Jira DC migration from outdated CentOS to AlmaLinux
• Designed a VM cluster optimized with IOPS and workload requirements, ensuring future
scalability
• Performed Jira upgrade across two major versions in a production-equivalent staging
environment
• Migrated HA database stack (DRBD/Pacemaker/Corosync) from CentOS 7 -> AlmaLinux 9.4
• Executed compatibility upgrades of MySQL (5.6 -> 8.0) and Java (7 -> 11->17) with full
functional validation
• Manually veri ed 100% of ScriptRunner components using structured test plans
• Removed 15+ legacy plugins and deprecated customizations through a targeted technical
audit
• Refactored 20+ broken Groovy scripts and successfully migrated 10 Python scripts to Groovy
with full regression testing
• Rewrote and modularized Ansible playbooks, reducing future deployment time by an
estimated 40%

Design & Architecture

• Proposed HA MySQL cluster design using HAProxy, Consul, VIP failover, and ACLs (not
implemented due to shifting priorities)
• Designed hardware tracking pipeline (Jira -> CCW-> Dashboard) with cross-team API
coordination
