You pay for servers that sit idle most of the day. You don't have to.

We build serverless backends on AWS Lambda, Google Cloud Functions and Azure Functions that scale with demand and cost little when traffic is quiet.

## Problems we solve

- We pay for servers around the clock for traffic that comes in bursts: Quiet nights, busy mornings, the same bill either way.
- Patching servers takes time we don't have: Security updates pile up while the team builds features.
- Our backend can't handle spikes: A campaign goes well and the app goes down.
- Our serverless app got messy and slow: Cold starts, tangled functions and costs that crept up.

## What we build

- Serverless APIs: Lambda or Cloud Functions behind API Gateway for web and mobile apps
- Event-driven workflows: Queues, EventBridge and webhooks that react to what happens in your business
- Background processing: File, image and video processing that scales with the workload
- Cost tracking: Cost per request and per feature, visible on a dashboard

## How we work

- Assess (1-2 weeks): We review your workload and traffic patterns and tell you whether serverless is the right fit.
- Design (2-3 weeks): We design functions, queues, events and data storage, and estimate monthly costs.
- Develop (4-6 weeks): We build the backend in sprints with automated tests and infrastructure as code, and demo it every week.
- Deploy (2 weeks): We deploy with monitoring, tracing and alerts, then tune for speed and cost after launch.

## Results

- Example: Video processing pipeline: For example, for a media app we would process each upload in its own function, so many videos run at once.
- Example: Low-cost backend: For example, for a startup we would move the API to Lambda and DynamoDB, so you pay only when requests come in.
- Example: Event-driven webhooks: For example, for a marketing tool we would put webhooks on a queue with functions that scale on their own.

## Questions

### Won't cold starts make the app slow?
They can if ignored. We choose runtimes carefully, keep functions small and use provisioned capacity for the few paths that need an instant response.

### Are we locked into one cloud?
Partly. Serverless uses each provider's services. We keep your business logic separate from cloud-specific code, so a future move is a contained job, not a rewrite.

### Is serverless always cheaper?
No. For steady, heavy traffic, containers can cost less. We estimate both before you decide.

### Who owns the setup?
You do. Code and infrastructure live in your repository and your cloud accounts. We sign an NDA before you share anything.
