Tadas Dilys

Automation & Monitoring Specialist

I keep critical services running and build the tools that make that easier — from Zabbix and incident response to Python, PowerShell and full-stack web apps.

About

I have 5 years of experience supporting critical IT services in 24/7 enterprise operations: monitoring, incident response, Microsoft 365 and Entra ID, ITSM and SOC L1 triage.

What I enjoy most is removing manual work. I build automation with Python, PowerShell, REST APIs and Microsoft Graph, and I have hands-on experience building full-stack web apps with React, Next.js, Tailwind CSS, Prisma and PostgreSQL.

I use AI tools daily and follow web development and AI closely. I'm looking for roles in SRE / operations, internal tool development and junior full-stack engineering.

Experience

  1. Monitoring Specialist

    Nov 2023 – Sep 2026

    UAB "Ignitis grupės paslaugų centras" · Vilnius

    • Supported 24/7 monitoring and incident response for critical IT services: operational logs, shift handovers, escalation and stakeholder communication.
    • Owned Zabbix operations across ~444 services and 1,000+ hosts — onboarded critical services, standardised templates and dependencies, and tuned triggers to improve alert quality.
    • Built an Entra ID + Microsoft Graph email-to-Ivanti automation that turns formatted requests into structured tickets and Teams notifications, saving ~3 hours/month and reducing manual-entry errors.
    • Resolved ~100 L1/L2 tickets per week for around 1,000 users with 95%+ SLA compliance, including access provisioning and multi-system permission issues.
    • Triaged SOC L1 security alerts (phishing reports, suspicious sign-ins and user activity) and performed containment: blocking senders, domains, IPs and file hashes, disabling access, resetting passwords and MFA.
    • Coordinated Major Incident Management: registered incidents, gathered technical teams in Teams, shared impact and monitoring data, and issued company-wide SMS and email communications.
    • Consulted other teams on monitoring, Zabbix, Ivanti and alert workflows, supporting stakeholders across Lithuania, Latvia, Estonia, Finland and Poland.
    • Wrote and maintained runbooks, knowledge-base articles and script documentation in Jira and Confluence.

    • Monitored server racks and customer environments remotely and on-site, responded to infrastructure alarms and coordinated fixes with customers and technical teams.
    • Co-developed a full-stack scheduling and customer-visit system that replaced a legacy process, cutting registration time from ~3 to ~1.5 minutes and improving data accuracy.
    • Designed the database schema and implemented authentication and back-end functionality, contributing to the front end when needed.
