We design, harden, and maintain sovereign server infrastructure for tech scale-ups, SaaS platforms, and privacy-focused European enterprises. Eliminate vendor lock-in, escape exorbitant VMware licensing, and achieve true data sovereignty backed by over two decades of senior Unix/Linux systems practice.
We operate as your senior technical studio. From bare-metal server provisioning and ZFS storage pooling to automated CI/CD pipelines and 24/7 SLA telemetry, our engineering eliminates guesswork.
Architecting high-availability (HA) Proxmox VE clusters with enterprise ZFS storage pools, distributed Ceph storage, and Proxmox Backup Server (PBS) client deduplication. Complete infrastructure sovereignty free from public cloud price volatility.
Fine-tuning PostgreSQL, MariaDB, and Redis for high-concurrency environments. Deep sysctl kernel parameter optimization, ZFS recordsize alignment, NVMe I/O scheduling, and query memory allocation (shared_buffers, work_mem).
Deploying Layer-7 Web Application Firewalls (WAF), nftables kernel packet filtering, CrowdSec community threat intelligence, and isolated WireGuard mesh VPN tunnels connecting remote engineering teams securely to core subnets.
Containerizing microservices with production Docker/Podman stacks. Designing reproducible CI/CD deployment pipelines (GitLab CI, GitHub Actions) featuring immutable artifacts, canary rollouts, and instant automated rollbacks.
Continuous infrastructure telemetry using Prometheus, Grafana, and Zabbix. Real-time alerting on memory pressure, storage IOPS saturation, and network bottlenecks allows us to remediate anomalies long before users feel latency.
Unlike pure software consultancies, our group holds certified electrical engineering qualifications. We understand servers from the copper power feed, ATS switches, and UPS batteries up to the OS routing layer.
Following Broadcom's acquisition of VMware and the forced transition to subscription bundles, IT executives face 300% to 1000% license cost increases. We provide full-lifecycle, zero-risk migrations of your production virtual machines to enterprise Proxmox VE.
Accurately plan your OpenZFS storage pools for Proxmox VE or bare-metal TrueNAS/Linux hosts. Calculates net usable storage, parity overhead, 80% performance headroom, and host ECC RAM recommendations.
4ECOM operates as the international systems engineering and Linux architecture division of the 4eSmart Group. Our multidisciplinary group delivers turnkey engineering across commercial building automation, certified high-voltage electrical infrastructure, and enterprise software.
Linux Administration & Enterprise SLA
Our dedicated Polish operational branch providing comprehensive Linux systems administration, Proxmox VE cluster support, emergency response, and contractual SLA agreements for companies operating across Poland.
Building Management Systems & Energy
Engineering enterprise automation for commercial facilities, offices, and warehouses. HVAC automation (VRV/VRF), dynamic energy peak shaving, daylight-harvesting DALI-2 lighting networks, and industrial bus integrations (Modbus, BACnet, KNX).
Premium Smart Home Automation
Specialized smart residential systems engineering for high-end luxury residences and modern villas. Built strictly on wired industrial Loxone architecture and private on-premise Home Assistant servers for uncompromising privacy.
Electrical Measurements & Distribution
Certified Polish Association of Electrical Engineers (SEP G1 Exploitation & Supervision) engineering. Periodic 5-year building inspections, PINB legal commissioning, Sonel precision instrument measurements, and automation control panel assembly.
Apartment Turnaround & Fit-Out
Turnkey technical maintenance, post-lease refurbishment, and swift apartment turnaround for commercial landlords, institutional build-to-rent (BTR) funds, and individual residential property investors.
Private Umami Cloud on PostgreSQL
All telemetry, analytics, and service metrics across the 4eSmart group run on our dedicated, private PostgreSQL instance on OCI. 100% GDPR compliant, zero third-party data tracking, and hosted entirely on our sovereign cloud stack.
We do not employ non-technical account managers. When you reach out to 4ECOM, your infrastructure requirements, Proxmox VE migrations, or SLA terms are assessed directly by senior engineers who write the configurations.
