Custom Software Built to Last

API & Backend Development

Typed APIs with auto-generated client SDKs, deployed on AWS serverless infrastructure — built with our open-source Lightning Server framework.

Your API Is the Foundation Everything Else Depends On

Your backend is the invisible layer that makes everything work. Mobile apps, web frontends, third-party integrations, internal tools — they all depend on a well-designed API to function correctly. When the backend is unreliable, slow, or poorly structured, every application that touches it inherits those problems. When it is solid, everything built on top of it moves faster and breaks less. Custom API and backend development is not a technical detail — it is the single most important architectural decision in your software stack.

Lightning Kite builds production-grade APIs and backends using Lightning Server, our open-source Kotlin backend framework. Lightning Server provides typed API endpoints that automatically generate client SDKs for every platform your app runs on. This eliminates API documentation drift — the problem where your backend and frontend slowly fall out of sync because someone forgot to update a spec. With Lightning Server, the client SDK is generated directly from the endpoint definitions, so frontend and backend are always in agreement. No manual documentation, no mismatches, no broken integrations.

We deploy primarily to AWS using serverless infrastructure including Lambda, API Gateway, DynamoDB, RDS, S3, and CloudFront. Serverless architecture means your backend scales automatically with demand and you pay only for actual usage rather than idle servers. This approach is production-proven across more than 204 web projects delivered since Lightning Kite was founded in 2006. Our team of 11-20 employees works together in our Logan, Utah office — no offshore handoffs, no communication gaps.

Why Choose Lightning Kite for API & Backend Development

We Built the Framework

Lightning Server is our own open-source backend framework, battle-tested across dozens of production projects. Because we maintain it, we know it inside and out — and we can extend it to fit your exact requirements without waiting on third-party support.

Typed APIs, Zero Drift

Lightning Server's typed endpoints automatically generate client SDKs for your frontend. When the API changes, the client updates with it. Your frontend and backend stay in sync without manual documentation, hand-written API specs, or integration surprises.

Realtime Built In

Lightning Server includes built-in WebSocket support for realtime communication. We have embedded chat in more than 12 applications and built realtime emergency communication tools and a live auction platform. If your app needs live data, we have done it before.

Technical Depth in API & Backend Development

Lightning Server: Typed Backend Development

Most backend frameworks require you to define your API endpoints in code and then separately write documentation, client libraries, and integration tests. This creates a fundamental synchronization problem: the documentation drifts from the implementation, the client library uses outdated types, and integrations break silently. Lightning Server solves this at the framework level.

In Lightning Server, every endpoint is defined with full type information — request body, response body, URL parameters, query parameters, and authentication requirements. From these typed definitions, the framework automatically generates client SDKs that your frontend team can use directly. When you add a field to a response object or change a parameter type, the generated client SDK updates to match. There is no separate API spec to maintain, no Swagger file to keep in sync, and no room for drift between what the server sends and what the client expects.

Lightning Server also includes built-in database abstraction, file handling, and authentication — the common infrastructure that every backend needs but that typically takes weeks to implement from scratch. This lets us focus development time on your business logic rather than reinventing plumbing. The framework is open-source and available on GitHub, so you are never locked in to a proprietary tool.

AWS Serverless Architecture

We deploy backends to AWS using a serverless architecture built on Lambda, API Gateway, DynamoDB, RDS, S3, and CloudFront. Lightning Server's key advantage here is deployment flexibility — the same application code runs on both AWS Lambda and a dedicated server (such as Netty) without any changes. You can start with serverless for cost efficiency and switch to a dedicated server when you need persistent connections or predictable latency, or vice versa. Serverless means there are no servers to provision, patch, or scale manually. AWS handles the infrastructure, and your backend scales automatically from zero requests to thousands of concurrent users without configuration changes.

The cost model is equally compelling. With serverless, you pay only for the compute time your API actually uses. A backend that handles 100 requests per day costs almost nothing. A backend that spikes to 10,000 requests during a product launch scales automatically and costs proportionally. There are no idle servers burning money overnight and no capacity planning guesswork. For the majority of applications, serverless is both more reliable and more cost-effective than traditional server-based deployments.

We use DynamoDB for workloads that need low-latency key-value access and RDS (PostgreSQL or MySQL) when relational queries and joins are required. S3 handles file storage and CloudFront provides global content delivery. This stack is production-proven across the 204+ web projects Lightning Kite has delivered since 2006.

Realtime Communication

Many applications require data to flow in both directions — not just request-response, but live updates pushed from the server to the client as events happen. Lightning Server includes built-in WebSocket support that makes realtime features a standard capability rather than a specialized add-on.

We have embedded realtime chat functionality in more than 12 production applications. Beyond chat, we have built realtime emergency communication tools that require sub-second message delivery, a live auction platform where bid updates must reach all participants instantly, and collaborative features where multiple users interact with shared data simultaneously. If your application needs live data, push notifications driven by server events, or bidirectional communication, we have the architecture and the production experience to deliver it reliably.

API Security

Security is not a feature we add at the end — it is built into Lightning Server at the framework level. Every endpoint is protected by default with built-in authentication and authorization. The framework enforces access controls so that unprotected endpoints are the exception, not the rule, and must be explicitly declared.

Beyond the framework defaults, we follow OWASP security best practices on every project. Input validation prevents injection attacks and malformed data from reaching your business logic. Rate limiting protects against abuse and denial-of-service attempts. All communication is encrypted in transit. Credentials and secrets are managed through secure systems — never hardcoded, never committed to source control. For clients in regulated industries, we work within your compliance requirements and provide documentation for security audits.

Integration and Interoperability

Most businesses do not operate on a single system. Your new backend needs to connect to existing databases, third-party APIs, payment processors, CRMs, ERPs, analytics platforms, and internal tools. We build APIs that serve as integration hubs — well-structured, well-documented interfaces that connect your ecosystem rather than adding another silo to it.

We handle data migration from legacy systems, backward-compatible API versioning so existing clients continue to work during transitions, and adapter layers that normalize data from disparate sources into a consistent format. With experience across 31 programming languages and partnerships spanning 9+ years with clients like VBI, we understand that backend development is not just about writing endpoints — it is about making systems work together reliably over the long term.
