Jakub owns the technology side of every project at Rotech Group. He combines implementation experience, hands-on knowledge of IT infrastructure and a calm approach to projects where security, stability and real control over the environment matter the most.

Technology should work in practice,
not just look good on a slide.
Jakub started his career very close to the technology itself: diagnostics, hardware service work, repairing computers and mobile devices, and direct contact with clients. As a result, he looks at IT in practical terms. Before he proposes a solution, he wants to understand how the environment actually works, where the problems show up and what is blocking the team's everyday work.
Over time he moved into infrastructure and implementation projects. He worked on ManageEngine solutions, IT security, Active Directory, Microsoft 365, infrastructure monitoring, log analysis, privileged access management and disaster recovery. He spent more than 4 years at MWT Solutions as an Implementation Specialist, delivering ManageEngine projects, including large, demanding engagements covered by NDA.
At Rotech Group he owns the technology side of projects. He designs the architecture, picks the tooling, runs the configuration and supports clients after go-live. His goal is not just to stand the system up, but to deliver a solution that actually tidies up IT work, increases security and gives the organization better control.
The most important thing for him is that technology stays understandable and useful. The system should help people do their work, not add another layer of chaos.
"A good implementation doesn't end with installing the system. It ends when the client understands the environment, has control over it and knows how to react before a problem hits the business."
- Jakub RoszkiewiczWhat Jakub is responsible for.
At Rotech Group, Jakub owns the technology side of projects: from environment analysis, through architecture choices, to configuration, training and post go-live support.
From technical service
to advanced IT implementations.
The technology perspective
in a team of three brothers.
Rotech Group brings three perspectives together: business, process and technology. Jakub owns the third one. He checks whether the solution will work stably, securely and sensibly inside the client's real environment.
Jakub owns the technical preparation and delivery of projects. He analyzes the client's environment, picks the architecture, configures the systems and makes sure an implementation does not stop at the software install.
His experience covers ManageEngine solutions used in infrastructure monitoring, Active Directory and Microsoft 365 management, log analysis, security, privileged access and disaster recovery.
In practice this means the client gets more than a tool. They get a structured way of working: visibility of the infrastructure, clear roles and permissions, alerts, reports, procedures and the know-how needed to keep the system running afterwards.
Jakub's perspective complements Mateusz's and Maciej's competencies. As a result, a project is not assessed purely on sales terms or purely on technical terms. It is analyzed end to end - from the business need, through the process, to a stable implementation.
Technical specializations.
ManageEngine solutions, infrastructure, security, monitoring, privileged access and IT process automation.
Implementations in demanding environments.
Jakub has worked on projects where stability, security, access control and effective management of IT infrastructure really mattered, including large engagements covered by NDA.
In many projects the environment details, organization names and project scope cannot be communicated publicly. So instead of a list of names, we focus on describing the real experience: monitoring, security, Active Directory, Microsoft 365, privileged access, log analysis and supporting IT teams after the system goes live.
Technical knowledge in practice.
Full Linux server monitoring with OpManager
A practical guide to configuring Linux monitoring in production environments. Key metrics, multi-level alerts and ManageEngine OpManager dashboards.
Why is Linux server monitoring critical?
Linux underpins IT infrastructure in companies around the world: web servers, databases, container systems. Without continuous monitoring, outages can cost an organization tens or hundreds of thousands of zlotys per hour of downtime.
Key metrics to monitor
- Availability - verifies whether the server is online and responding to requests
- Response time - latency of the services and applications running on the server
- CPU utilization - percentage CPU load; an alarm signal above 80-90%
- Memory utilization - usage of RAM and swap; memory leaks lead to application crashes
- CPU load - queue of processes waiting to be executed at a given moment
- Load average - smoothed system load over 1, 5 and 15 minutes
- Disk usage - monitoring free space; filling up the
/partition can lock up the whole system
How does OpManager automate monitoring?
ManageEngine OpManager offers agentless monitoring via SNMP, SSH and WMI. Configuring multi-level alert thresholds enables early detection of problems: green / yellow / orange / red colors on the dashboards signal the current state of each parameter.
Notifications are sent automatically via email or SMS once metrics cross defined thresholds. OpManager dashboards present a full real-time view of the infrastructure, with drill-down down to the level of a single process or service.
Thanks to alert automation and central dashboards, IT teams can react proactively, before users even notice the problem.
ManageEngine OpManager - official product page ↗Healthcare cybersecurity: 6 steps to securing data
An analysis of threats and practical recommendations for protecting medical data. A 6-stage process for securing ePHI using ManageEngine DataSecurity Plus.
Why is medical data especially exposed?
The healthcare sector processes ePHI (Electronic Protected Health Information): information that is extremely sensitive and highly valued by cybercriminals. HIPAA and GDPR impose strict requirements on protecting it, and a breach can result in financial penalties reaching millions of zlotys and lasting reputational damage.
6 steps to securing patient data
Scan for ePHI
Automatic discovery of files containing patient data through keyword and pattern matching (PESEL numbers, insurance numbers, diagnostic data). Scanning covers network shares, file servers and cloud.
Risk assessment
Analysis of the sensitivity of the discovered data combined with an evaluation of user permissions: who has access to which files? Identifying overprivileged accounts as the main source of insider risk.
File classification
Automatic tagging and categorization of documents by sensitivity level: public, internal, confidential, strictly confidential. Classification lets you apply the right security policies per data category.
File access auditing
Monitoring every access event: read, write, delete, rename. Detection of anomalies typical of ransomware attacks (mass encryption) or unauthorized copying of patient data.
Data transfer monitoring
Tracking activity in the cloud, transfers to external media (USB) and email transmissions. Real-time alerts when confidential ePHI leaves the organization without authorization.
Rolling out a DLP strategy
Configuration of Data Loss Prevention policies: blocking unauthorized transfers, enforcing file encryption, automatic quarantine of suspicious documents and HIPAA/GDPR compliance reporting.
Full deployment of all 6 steps is supported by ManageEngine DataSecurity Plus: a platform that combines file auditing, data classification and DLP in a single tool.
