Peter Dongo

I build the platforms teams ship on.

And the products that run on top of them. Kubernetes, GitOps and infrastructure-as-code by day - six shipped apps, designed and built end to end, by night.

§ 01
distinction

Certified deeper than almost anyone in cloud-native.

Thirty-four active certifications, fourteen of them CNCF - and both Kubestronaut distinctions, including the Golden one held by only a few hundred engineers worldwide.

Golden Kubestronaut

elite

Awarded Apr 2025 for holding the full suite of CNCF certifications plus additional Linux Foundation credentials.

Kubestronaut

Awarded May 2024 for holding all five CNCF Kubernetes certifications - CKA, CKAD, CKS, KCNA and KCSA - at once.

§ 02
selected work

Six products, shipped solo.

Designed, built and shipped end to end - privacy-first by default, with the heavy lifting done on-device. Each one started as a problem I wanted solved for myself.

01

Fingertips

macOS · iPadOS · iOS live

Everything you reuse, one keystroke away.

The text, images and files you send over and over, kept in one place and handed back wherever you're typing - a hotkey on the Mac, the same library as a keyboard on iPhone and iPad. Screenshots are searchable by the words inside them, understood entirely on-device.

Fingertips - snippet library
02

FrostCam

macOS live

Pause your webcam - without the black screen.

A virtual camera that freezes a frame or loops a few seconds with smooth transitions, so you can step away from a call without awkwardly going dark. Installed as a system extension; all processing is local and nothing leaves the device.

03

Névtárs

iOS · Android live

A couple's companion for choosing a baby name.

Swipe through 4,700+ official Hungarian names, sync in real time with your partner and get instant matches. Filter by origin, rarity and name day, then settle the shortlist with a playoff round.

04

MeterTab

macOS · iOS · watchOS live

Know exactly how much AI you have left.

A menu-bar meter for AI usage, spend, limits and resets across Claude, OpenAI, Cursor and Codex - and the only one your agents can talk to over MCP, so they self-throttle instead of dying at a hard limit. Local-first; buy once, use on Mac, iPhone and Watch.

05

DropRoost

iOS · iPadOS · macOS live

Track the price you actually pay - not $0.00.

An App Store wishlist for in-app purchase and subscription prices - the ones every other wishlist shows as free, because the price you are really waiting on lives inside the app. A server watches around the clock and pushes an alert when one drops, with full history and cross-region comparison.

06

WarmCam

macOS live

Look your best on every video call.

Real-time GPU enhancement - skin smoothing, warm lighting, colour grading and background blur - working as a system camera across Zoom, Meet, Teams and everything else. Private by design: the whole pipeline runs on-device.

§ 03
practice

Three disciplines, one throughline.

01

DevOps & Platform Engineering

Cloud-native platforms on Kubernetes and Azure - GitOps delivery, infrastructure-as-code and CI/CD that teams ship on with confidence, with security and policy built into the platform rather than bolted on.

02

AI Engineering

LLMs, agents and the Model Context Protocol inside real engineering workflows - automating the dull parts, building intelligent product features, and running internal enablement so colleagues can do the same.

03

App Development

Polished, privacy-first apps shipped end to end - Swift on macOS, iOS and watchOS, the Go backend behind them, the landing page, the pricing and the support inbox.

§ 04
credentials

34 active certifications.

Across applied AI, Kubernetes, cloud-native, GitOps, Azure, infrastructure and cost automation. Not a wall of logos - the map of what I've actually gone deep on.

Building something cloud-native? Let's talk.

Platform work, AI engineering, or a product you want shipped properly - I'm open to interesting conversations, contracts and roles.
