Hi, I’m Doğan Aydın 👋

Principal/Staff-minded backend engineer focused on distributed systems, cloud-native architecture, and high-performance services. I like building tools that stay small, deterministic, and operationally boring.

What I build

I’m drawn to problems where correctness, latency, and operability matter:

  • Workflow / job runtimes (durable execution, replay, idempotency)
  • Reliability tooling (incident forensics, debugging, log intelligence)
  • Terminal-first developer tools (TUI/CLI) that replace “yet another dashboard”

Featured projects

🔁 Retcon — deterministic workflow runtime (Go)

Retcon is a lightweight workflow runtime backed by SQLite (WAL) — no Redis, no Postgres, no RabbitMQ. It treats crashes as normal and makes replay a first-class primitive. Repo: https://github.com/dgnydn/retcon

🧪 dlqautopsy — dead-letter forensics (Go)

A CLI-first dead letter “autopsy” engine: ingests DLQ messages, groups failures deterministically, reconstructs timelines, and produces actionable reports — offline-first with local SQLite. Repo: https://github.com/dgnydn/dlqautopsy

🩺 Ferris Pulse — service health checker (Rust)

A terminal dashboard for monitoring HTTP/TCP/ICMP/DNS/TLS with hot-reloaded config and a built-in REST API. Repo: https://github.com/dgnydn/ferris-pulse

☸️ k8s-pod-log-analyzer — Kubernetes logs in a TUI (Go)

Interactive log analysis for Kubernetes pods: smart pattern recognition, stats, and English/Turkish UI support. Repo: https://github.com/dgnydn/k8s-pod-log-analyzer

🛰️ nmap-tui — visualize Nmap results (Go)

Modern TUI for Nmap XML: host/port views, search/filtering, scan-from-UI, and progress display. Repo: https://github.com/dgnydn/nmap-tui

Tech I use

Systems: Go, Rust, Linux, networking
Backend: HTTP APIs, queues, workers, observability
Cloud/Infra: Docker, Kubernetes, CI/CD
Product: Next.js, TypeScript when I need a sharp frontend

Writing & notes

  • Portfolio / blog: https://www.doganaydin.net
  • I like writing “why we didn’t build a platform” style notes: fewer moving parts, more clarity.
