SDK Development: Make Your Platform Easy to Build On
Great SDKs turn an API into an ecosystem. We build idiomatic, well-tested and well-documented SDKs for web, mobile, desktop, server and hardware platforms so developers can integrate with you in minutes.
Developer experience drives adoption
Developers judge your product by how quickly they can get it working. A clean SDK with sensible defaults, typed models, clear errors and copy-paste examples dramatically reduces integration time and support tickets.
ENGIMANDI builds SDKs that feel native in each language, following its naming conventions, packaging, async patterns and error handling. We combine code generation from OpenAPI / Protobuf with hand-written ergonomic layers, then publish to npm, PyPI, Maven, NuGet, CocoaPods and Swift Package Manager.
What you get
- Idiomatic SDKs in multiple languages
- Typed models and clear error handling
- Auth, retries, pagination built in
- Sample apps & quick-start guides
- Reference docs generated from code
- Semantic versioning & changelogs
- Automated tests across versions
- CI publishing to package registries
Types of SDKs we build
From REST API wrappers to low-level native libraries.
API Client SDKs
JavaScript / TypeScript, Python, Java, C#, Go, PHP and Ruby clients for your REST or GraphQL API.
Mobile SDKs
Android (Kotlin) and iOS (Swift) SDKs, plus Flutter and React Native plugins, with small footprint.
Plugin & Extension SDKs
Let third parties extend your product with plugin APIs, sandboxing and marketplaces.
Hardware & Device SDKs
C / C++ SDKs with language bindings for scanners, sensors, machines and IoT devices.
CAD & Geometry SDKs
Libraries for DXF / DWG / STEP processing, geometry calculations and CAD plugin frameworks.
AI Agent SDKs
SDKs and tool kits that let developers connect AI agents to your platform safely.
Languages & tools
We ship SDKs wherever your developers are.
Typical projects
- Official SDKs in 6 languages for a SaaS API
- Payments or KYC SDK for Android and iOS apps
- C++ SDK with Python bindings for a measurement device
- Plugin SDK for a desktop engineering application
- Analytics SDK with offline batching
- Refactoring a legacy SDK for better developer experience
How we build SDKs
Audit
Review your API, target developers and languages.
Design
Public interface, naming and examples agreed first.
Build
Generated core plus hand-crafted ergonomics.
Document
Guides, references and working sample apps.
Publish
Automated releases to package registries.
SDK development questions
What is the difference between an API and an SDK?
An API is the interface your server exposes. An SDK is a ready-made library in a specific language that makes calling that API easy, handling auth, retries, models and errors for the developer.
Do you only generate SDKs automatically?
No. Generators are a starting point. We add idiomatic wrappers, helpers, docs and tests so the SDK feels hand-written.
Can you maintain SDKs as our API changes?
Yes. We set up pipelines that regenerate, test and release SDKs whenever your API specification changes.
Do you build open-source SDKs?
Yes. We can prepare repositories, licences, contribution guides and CI for public GitHub projects.
