MZSoft Studio
Yongliang Wang
Senior Platform Engineer — 15+ years of Golang, Kubernetes and multi-cloud infrastructure. Also the one person behind 23 shipped App Store products.
Most of my career has gone into the layer nobody sees: multi-cloud asset synchronisation, monitoring that holds up across 10,000+ nodes, delivery pipelines that turned months of provisioning into weeks. The rest has gone into shipping products end to end on my own — which is a fast way to learn what infrastructure decisions actually cost the people building on top of them.
What I'm looking for
Berlin · hybrid or remotePlatform / Cloud / DevOps
Where the last seven years went: multi-cloud asset synchronisation, monitoring and alerting across 10,000+ nodes, Infrastructure-as-Code delivery, and the Kubernetes and OpenStack estates underneath it all.
Backend Engineering (Go)
Golang is the primary language — gRPC services, Kafka pipelines, asynchronous task processing tuned for high-concurrency workloads, and the data layer that keeps them honest.
iOS / Apple Platforms
The other half of the story: 23 App Store products built solo, including on-device AI. Swift and Objective-C, SPM packaging of native C++ runtimes, and a release pipeline that runs without manual steps.
By the numbers
From high-traffic game backends in 2009 to multi-cloud security platforms — backend and infrastructure, continuously.
Monitoring and alerting infrastructure scaled across multi-cloud environments at Qi-Anxin.
Through asynchronous processing and queue optimisation — one of several throughput wins on the same platform.
Designed, built, localized, released and supported solo across iOS, iPadOS, macOS, watchOS and Chrome.

Selected work
Open sourceA translation toolkit for Xcode String Catalogs. Takes a Localizable.xcstrings, fans the strings out across Google, DeepL, Baidu and OpenAI concurrently, and writes a merged catalogue back without destroying existing translations or format specifiers.
Localizing 23 apps by hand is not a strategy.
View on GitHub →A proxy server in front of OpenAI-compatible APIs: key management, provider routing, quota enforcement, and an admin interface so configuration is not a YAML file someone has to SSH in to edit.
One control point for every LLM call across the portfolio.
View on GitHub →A two-step App Store rating prompt and in-app feedback form, with a Cloudflare Worker collecting reports, screenshots and device context. Ships as an SPM package; the backend runs at the edge.
Replaced a mailto: link that collected nothing useful.
View on GitHub →Self-hosted Swift Package Manager distributions of ONNX Runtime and sherpa-onnx, packaged as xcframeworks and served from GitHub Releases so Xcode Cloud builds resolve reliably instead of depending on an upstream mirror.
On-device speech and vision models need a build system that does not flake.
View on GitHub →Pull AI models down to a machine in one command, with source, cache layout and resume behaviour handled for you.
The setup step that kept being rewritten in every project.
View on GitHub →The gin web framework wired to Uber's dig dependency-injection container, so handlers get their dependencies declared instead of imported from a global.
Testability, mostly.
View on GitHub →The product side
Outside the platform work I run MZSoft Studio — a 23-product portfolio spanning photo and media tools, productivity utilities, navigation instruments and developer tooling. On-device AI for photo restoration, colorization and speech transcription; Cloudflare Workers for the small amount of backend that exists; a release pipeline that takes a build from commit to App Store review without manual steps.
It is the closest thing to running a product engineering org that one person can do, and it is where the recent Swift, Go and edge-infrastructure work lives.
