SERVICES / 9NE.PL
Technology from diagnosis
to production deployment.
VoIP, Linux, security, web applications, automation and incident response — expertise combined around how your system actually works.
TELEPHONY / REAL-TIME COMMUNICATION
VoIP, SIP and PBX
Design and maintenance of telephony platforms, call routing, WebRTC, NAT, media, carrier integrations and advanced signalling diagnostics.
- FusionPBX / FreeSWITCH / OpenSIPS
- SIP traces, RTP and Wireshark
- HA, migrations and trunk integrations
SYSTEMS / PRODUCTION OPERATIONS
Linux and infrastructure
Building, migrating and stabilising production environments. Configuration of services, networks, reverse proxies, containers, monitoring, backups and recovery procedures.
- Debian / Ubuntu / RHEL
- Docker, Nginx and systemd
- Migrations without unnecessary risk
SECURITY / HARDENING
IT security
Configuration reviews, attack surface reduction, system hardening, scan analysis and practical vulnerability remediation without destabilising production.
- Audits and risk analysis
- Firewall, TLS and access control
- Safe deployment of changes
PRODUCT / WEB ENGINEERING
Web applications
Custom panels, operational tools and websites. Frontend and backend built for straightforward maintenance, security and a real business process.
- Python, APIs and databases
- Modern frontend
- Deployment and maintenance
AUTOMATION / DATA
Automation and reporting
Scripts, integrations and reports that reduce manual work. I automate repetitive operations, aggregate data and build tools to simplify everyday system management.
- Python, Bash and scheduling
- API integrations and data processing
- Technical and business reports
TROUBLESHOOTING / RCA
Diagnostics and incident response
Intermittent problems across multiple layers that are difficult to reproduce. Analysis of logs, network traffic and application dependencies, followed by a lasting fix and documentation.
- RCA rather than quick workarounds
- tcpdump, Wireshark and log correlation
- Remediation and prevention
NOT SURE WHERE TO START?
Describe the problem or the outcome you need.
A short discovery discussion can define the scope: your environment, risks, users and the most important outcome.
