İsmail Perim

I build things that
keep other things running.

Senior DevOps Engineer by day, indie app maker and automation tinkerer by night. 14+ years of building infrastructure, backends, and tools — from enterprise banking systems to smart meters to iOS apps.

What I Do

Infrastructure & DevOps

Docker Swarm, Kubernetes, Terraform, Ansible, Proxmox, GitLab CI/CD. Large-scale systems serving global banks and millions of IoT devices.

Backend Development

.NET Core, C#, REST APIs, RabbitMQ, Redis. PostgreSQL, MSSQL, MongoDB, Oracle. Microservices that handle real-world load at scale.

Monitoring & Observability

Prometheus, Grafana, Icinga. Building dashboards, alerting pipelines, and iOS apps for on-the-go system monitoring.

Automation & IoT

n8n workflows, Vapi AI assistants, Arduino, Raspberry Pi. From smart greenhouses to AI-powered phone systems — if it can be automated, I'll automate it.

Apps

iOS tools I build and ship on the App Store.
