Full-Cycle Engineering Expertise.
We specialize in the technical foundations of modern business. From container orchestration to browser-based productivity tools.
DevOps & CI/CD Automation
Dockerized production services and automated GitLab CI/CD pipelines. Declarative server fleets with NixOS/Colmena, configured with Ansible and Terraform.
Linux Infrastructure & Networking
Production Linux and network engineering: HAProxy load balancing, iptables/SNAT firewalls, BGP routing, CoreDNS, and traffic shaping (tc / fireqos).
Proxy & VPN Platform Engineering
Network-heavy proxy and VPN systems built for reliability: SoftEther/OpenVPN, Shadowsocks, and custom HTTP/SOCKS5 proxy servers across multi-country infrastructure.
Browser Extensions (Manifest V3)
Cross-browser Chrome & Firefox extensions: service workers, declarativeNetRequest, proxy/auth and network behaviour, and MV2 to MV3 migrations.
Monitoring & Observability
Self-hosted Prometheus, Grafana, and Alertmanager on Kubernetes (ArgoCD GitOps + Helm), with SNMP/blackbox exporters and hand-written PromQL alerting.
Production Incident Response
Calm, root-cause debugging of production incidents — downtime, bandwidth abuse, DDoS, and container crashes — favouring maintainable fixes over workarounds.
