🛠️ Not a Dev. Not an Engineer.

Just a bored SRE who builds Linux desktop apps and writes Rust until it compiles.

🧑‍💻 Who I Am

Just a Site Reliability Engineer who got bored and started building Linux desktop apps for fun.
Now I'm deep into Rust + QML, drinking too much coffee, and dealing with very questionable error handling.

💡 Engineer by heart. Degree? Yes - just not the kind that prepares you for lifetimes of lifetimes or why the borrow checker hates you.

I’ve scaled more pods than a Kubernetes dashboard in crisis, debugged production with only journalctl and sheer panic,
and lived through enough man pages and Stack Overflow threads to earn a PhD in "it worked on my machine."

💻 Linux-first. Rust-second. Sanity… somewhere in swap.
🛠️ I make servers behave and desktops do new tricks.
🧘 Calm during kernel panics - but panics on unwrap(None) during cargo run.
🪟 If it breaks on Windows… yeah, probably not my fault.
📦 "It works on my Nix shell 🐚" is the new "it works on my machine."

🔍 Philosophy

Code should fail loudly, log usefully, and compile eventually.
If it’s not observable, it doesn’t exist.
Everything should have a --help flag.
Never trust anything that works only on staging.

🧘 SRE Brain, Rust Fingers

🛠️ Rust Habits

🧵 Async where it matters. Blocking where it counts.
🚨 Panics on _unwrap(None) during cargo run.
🛠️ cargo check, cargo clippy, cargo fix... in that order.
🎯 cargo check before cargo pray.
📚 Reads std::error::Error like bedtime poetry.
🧪 Result<T, E> believer. Retries with backoff.
🔁 Never forgets to impl Retryable on life lessons.
👣 Follows traces like a bloodhound through tokio tasks.
🕵️‍♂️ Logs in JSON, thinks in traces.
📉 Metrics before mutability.
🔥 Tests in prod - but safely.

☸️ Kubernetes / SRE Mindset

🧘 Calm during kernel panics.
💾 Hates state, trusts etcd.
🔒 Ingress locked tighter than prod secrets.
📦 Sidecars are friends. InitContainers are therapy.
🔁 Can roll back a broken CDR in <30s.
📊 Prometheus whisperer. Reads Grafana like tarot.
🌐 DNS broken? Probably CoreDNS again.
🛑 Won’t deploy if livenessProbe isn’t passing.
📉 Knows when to scale down, when to evict.
🐳 Doesn’t trust anything that runs outside the cluster.
☸️ Speaks fluent kubectl, dreams in YAML.
🔍 If it’s not in otel, did it even happen?

🧯 Production Mindset

👷 Builds infra like Rust: safe, concurrent, no undefined behavior.
📦 Rolls out with canary, rolls back with git revert.
🔍 RCA enthusiast - blameless, but thorough.
⏱️ Latency budget is sacred.
🔧 Owns the on-call pager and the panic trace.
🙏 Prometheus, Alertmanager, and the occasional prayer.

🧰 Stack & Tools I Actually Use

🧠 Languages & Markup

Rust 🦀, QML, TOML, YAML, HTML, JSON

🛠️ Dev & Terminal Tools

Neovim + LSP, tmux, cargo, ripgrep, lazygit, RustRover
Shells: fish (with omf), also bash when necessary
Prompt: starship
CLI favorites: fd, rg, bat, exa, zoxide, lsd, ranger, tldr, jq

☸️ Kubernetes & Infra Stack

Clusters: Kubernetes, Podman, Docker, systemd, Flatpak, D-Bus
Tools: k9s, kubectl, stern, Lens, Helm, minikube, kind
Monitoring: Prometheus, Alertmanager, Grafana
Tracing: OpenTelemetry, Jaeger, Tempo, bpftrace, strace
Debugging: journalctl, htop, ctop, ncdu, dig, ip

📦 Infrastructure as Code (IaC)

Terraform - when I have to use the cloud
Ansible - config that survives longer than me
Pulumi - IaC with types? yes.
Helm - the only Helm chart I don’t hate is mine
Nix - declarative setups, reproducible everything

🚀 CI/CD Stack

GitHub Actions - the reliable default
Argo CD - GitOps, minus the pain
Flux, Drone, Earthly - when YAML doesn’t suck

🛡️ DevSec / Security Tools

Trivy - scan first, deploy later
Clippy - petty, but right
cargo-audit - because supply chains are scary
Dockle - container linting because I forget flags
gitleaks - secrets belong in vaults, not Git
pre-commit - guards against 3 AM commits

🖼 GUI App Stack

Qt / QML - for Linux-native UI
Tauri - Rust meets web UI without Electron bloat
Desktop Envs: KDE Plasma, Sway (Wayland > X)

🗃️ Databases I Actually Trust

PostgreSQL - when structure matters
Redis - for fast, ephemeral chaos

I don’t trust any DB that doesn’t survive a power cut or SIGKILL.

📌 Work in Progress

➡️ WhisperDesk - WhatsApp-style encrypted messaging app (Rust + QML)
➡️ Flatpak builds - because I use them
➡️ Sysadmin CLI tools - built from rage and repetition
➡️ Dotfiles & theming - terminal & KDE configs
➡️ Contributing to openSUSE tooling - someday soon™

🧯 Bonus Facts

Yes, I’ve used etcd in prod.
No, I don’t enjoy YAML.
I have beef with Cargo.lock.
I believe panic!() should print a dad joke.
I’ll fix my README... eventually.

This README is a living document - kinda like my dotfiles: never done, just slightly less broken each time.
