Consistent High Traffic
If your app has steady, predictable load 24/7, traditional servers or containers often cost less. The serverless premium makes sense for variable workloads, not constant ones.
Serverless Development Services
Build scalable, cost-efficient backends that scale to zero and handle traffic spikes automatically. AWS Lambda, Google Cloud Functions, Azure Functions—we design serverless architectures that cut infrastructure costs by 60-80%.

Serverless Development Services
End-to-end serverless solutions from architecture to deployment
AWS Lambda Development
Functions that scale automatically with pay-per-execution pricing. API Gateway integration, SQS triggers, S3 event handlers—entire applications on Lambda that cost pennies to run.
Serverless API Development
REST and GraphQL APIs on AWS API Gateway, Firebase Functions, or Vercel. Cold starts optimized, connection pooling handled, and observability built in from day one.
Event-Driven Architecture
SNS, SQS, EventBridge, Pub/Sub. Backends that react to events instead of polling. Great for data pipelines, webhook processors, and async workflows.
Serverless Migration
Migrate existing applications to serverless. We identify which workloads benefit from serverless and create a phased migration plan that minimizes risk.
Google Cloud Functions
Serverless backends on Google Cloud Platform. Firebase Functions for real-time apps, Cloud Run for containerized workloads, Cloud Pub/Sub for messaging.
Azure Functions Development
Serverless solutions on Microsoft Azure. Durable Functions for complex workflows, Event Grid for event-driven architectures, integration with Azure services.
Serverless + Container Hybrid
The honest approach: serverless for spiky workloads, containers for steady traffic. We design systems that use each pattern where it makes sense—not serverless-everything for the sake of it.
Serverless Consulting & Architecture
Not sure if serverless is right? We assess your workloads, estimate costs, and design architectures. Get a clear picture before committing—whether you build it yourself or hire us.
Why Choose Us for Serverless Development
AWS & GCP Certified Expertise
We've deployed production serverless applications handling millions of events. Lambda, API Gateway, DynamoDB, Step Functions—we know the platform deeply.
Honest Assessment
We'll tell you when serverless isn't the right fit. Our goal is the best solution for your problem, not pushing serverless onto every project.
Cost Optimization Focus
Serverless can be cheaper or more expensive depending on how you architect. We design for cost efficiency—proper timeouts, right-sized functions, and smart caching.
Cold Start Optimization
We know the tricks: provisioned concurrency, warm-up strategies, code optimization. Cold starts don't have to ruin user experience.
Infrastructure as Code
Everything deployed via Serverless Framework, SAM, or Terraform. Reproducible, version-controlled, and auditable infrastructure.
Full-Stack Integration
We build frontends too. Your serverless APIs are designed with real frontend requirements in mind—not theoretical abstractions.
When Serverless Makes Sense
Serverless isn't always the answer. Here's when it excels:
Apps with traffic that spikes and drops—marketing campaigns, seasonal businesses, viral potential. You pay only for what you use, scaling to zero when idle.
Webhooks, file processing, notifications, data pipelines. Tasks triggered by events rather than constant requests are perfect for serverless.
Minimal infrastructure cost while you find product-market fit. Scale from 10 users to 10,000 without re-architecting. Focus on features, not servers.
Small, focused functions that do one thing well. Each function scales independently, deploys independently, and fails independently.
When infrastructure costs matter—side projects, internal tools, low-traffic applications. Serverless can reduce costs by 60-80% compared to always-on servers.
Skip infrastructure setup entirely. Deploy functions in minutes, not days. Focus engineering time on features, not DevOps.
When Serverless Might Not Be Right
Long-Running Processes
Lambda has a 15-minute timeout. Video processing, complex ML inference, or long-running batch jobs need different solutions—containers, Fargate, or dedicated servers.
Cold Start Sensitivity
If every millisecond matters and you can't tolerate occasional cold starts, warm servers provide more consistent latency. We can mitigate cold starts, but not eliminate them.
Complex State Management
Serverless functions are stateless by design. Applications requiring complex session state or persistent connections may be better served by traditional architectures.

FaQ
Serverless development means building applications using cloud services that automatically scale and charge only for actual usage. You write functions that run in response to events—no servers to provision, maintain, or scale. AWS Lambda, Google Cloud Functions, and Azure Functions are the main platforms.
Cold starts are real but manageable. Typical cold starts are 100-500ms for Node.js/Python. We optimize function size, use provisioned concurrency for latency-sensitive endpoints, and design architectures that minimize cold start impact. For most applications, users don't notice.
AWS Lambda is the most mature with the richest ecosystem. Google Cloud Functions are great if you're already on GCP or need Firebase integration. Azure Functions work well in Microsoft-heavy environments. We recommend based on your existing infrastructure and specific needs.
Node.js, Python, and Go are our primary choices for Lambda—they have the fastest cold starts. Java and .NET are supported but have longer cold starts. We choose based on your team's expertise and project requirements.
DynamoDB is the serverless-native choice—scales automatically with no connection limits. Aurora Serverless works for relational data. Traditional databases (RDS, MongoDB) work but need connection pooling. We design data architecture alongside compute.
Local development with SAM or Serverless Framework, unit tests for business logic, integration tests against deployed resources. AWS X-Ray for distributed tracing, CloudWatch for logs and metrics. Debugging serverless requires different patterns—we have them down.

It depends on your traffic pattern. For variable workloads with quiet periods, serverless can be 60-80% cheaper since you pay nothing when idle. For consistent high traffic 24/7, traditional servers may be more cost-effective. We provide cost projections during our assessment.
Yes, we do serverless migrations. We assess your current architecture, identify which components benefit from serverless, and create a phased migration plan. Not everything should be serverless—we're honest about what should stay on containers or servers.
Serverless has security advantages: no servers to patch, automatic isolation, reduced attack surface. We implement proper IAM roles, encrypt data at rest and in transit, validate inputs, and follow cloud security best practices. For sensitive applications, we conduct security audits.
Yes. Lambda scales automatically to thousands of concurrent executions. We've built serverless systems handling millions of events daily. The key is proper architecture—async processing, queue-based workflows, and efficient function design.
Absolutely. We offer serverless assessments, architecture reviews, and cost analysis. You'll get a detailed report with recommendations you can implement yourself or hire us to build.
Lambda has a 15-minute timeout. For longer processes, we use Step Functions to chain functions, AWS Fargate for containerized workloads, or traditional servers. We design hybrid architectures that use serverless where it fits.
