Our Esteemed Clients

Leverage AWS API Gateway to Build Secure, Scalable, and Event-Driven Applications

At Rambunct, we help organizations accelerate innovation by implementing secure, scalable API-driven architectures using Amazon API Gateway. Our solutions are designed to support both serverless and container-based applications, integrating seamlessly with services like AWS Lambda, Amazon ECS with Fargate, Amazon Cognito, DynamoDB, SQS, and EventBridge. We design and deploy resilient API infrastructures with fine-grained authentication, throttling, and observability enabled through CloudWatch and X-Ray. From healthcare platforms like ChargeHealth, where API Gateway powers real-time serverless workflows, to high-throughput data processing systems like JoyfulHealth, where APIs securely front ECS microservices, Rambunct ensures every API Gateway deployment is compliant, cost-optimized, and aligned with AWS Well-Architected best practices.

API-Driven Application Solutions with Amazon API Gateway

AWS provides fully managed API management capabilities through Amazon API Gateway, enabling organizations to create, publish, maintain, monitor, and secure RESTful and event-driven APIs at scale. API Gateway allows applications to integrate seamlessly with backend compute such as AWS Lambda, Amazon ECS/Fargate, or on-premises services, while providing built-in capabilities for authentication, authorization, throttling, caching, monitoring, and logging. Whether you are building serverless applications, microservices, or high-throughput data platforms, API Gateway delivers resilient, low-latency APIs without the complexity of managing physical infrastructure.

At Rambunct, we specialize in architecting and deploying production-grade API Gateway solutions that align with the AWS Well-Architected Framework. Our expertise spans serverless and containerized environments, integrating services like Cognito for authentication, SQS and EventBridge for decoupled workflows, and CloudWatch/X-Ray for observability. From healthcare SaaS platforms like ChargeHealth, where API Gateway enabled low-latency event-driven interactions, to large-scale claims processing at JoyfulHealth, where APIs securely fronted ECS microservices, Rambunct ensures every API Gateway deployment is secure, auditable, scalable, and cost-optimized.

We design modular, API-first architectures that include API schema definitions, stage deployments, caching, throttling, and security policies. Our delivery model ensures compliance with AWS Well-Architected principles and supports both greenfield builds and modernization initiatives.

We implement multi-environment APIs (dev, staging, prod) with usage plans, quotas, and IAM roles for least-privilege access. Authentication is handled with Cognito or custom authorizers, and private integrations are supported through VPC Links for sensitive workloads.

API Gateway deployments are fully automated using AWS CDK or CloudFormation, integrated into CI/CD pipelines with CodePipeline, CodeBuild, and CodeDeploy. This enables repeatable, version-controlled deployments with rollback capabilities.

Every API Gateway deployment includes CloudWatch Logs, metrics dashboards, and alarms for error rates, latency, and throttling. Distributed tracing is enabled with AWS X-Ray, providing end-to-end visibility across API calls and backend services.

We tailor caching strategies, integration patterns, and cost controls to workload-specific requirements. For example, ChargeHealth APIs were optimized with provisioned concurrency and dynamic scaling to reduce cold starts, while JoyfulHealth APIs leveraged VPC Links and ECS integration for high-throughput processing.

Rambunct’s AWS API Gateway Expertise

We unlock the full potential of Amazon API Gateway to deliver secure, scalable, and event-driven API solutions tailored to customer workloads.

Managed API Deployments with API Gateway

  • Rambunct designs and deploys APIs with defined stages, usage plans, throttling, and quotas.

  • Infrastructure automation ensures rapid provisioning and version-controlled deployments via AWS CDK and CloudFormation.

Built-In Security & Access Control

  • API Gateway is integrated with Amazon Cognito and IAM for authentication and authorization.

  • Resource policies, WAF integration, and least-privilege IAM roles enforce strong access security.

High Availability & Resilience

  • APIs are deployed across multiple environments (dev, staging, prod) with stage-level monitoring.

  • Backend integration failures are mitigated with retries, DLQs, and event-driven patterns using SQS and EventBridge.

Performance Optimization & Monitoring

  • CloudWatch dashboards track latency, 4xx/5xx error rates, and request volume in real time.

  • X-Ray tracing provides full visibility into API calls, backend latency, and integration performance.

DevOps & CI/CD Friendly Workflows

  • API deployments are automated with CI/CD pipelines (CodePipeline, CodeBuild, CodeDeploy).

  • Version-controlled API definitions (Swagger/OpenAPI) enable repeatable rollouts and quick rollback.

Compliance & Regulatory Alignment

  • Logging, tracing, and IAM auditing ensure compliance with HIPAA, SOC 2, and industry-specific requirements.

  • Secure VPC Links and private integrations protect sensitive data flows in regulated workloads.

Its been great working with Neo on our solution landscape over these past few weeks. He has provided helpful insight into the AWS platform and recommended a number of best practice options for us to consider.
Stu Waldron

Stu Waldron

I handed Neo an usual request, how to put our open source modeling tool for travel retail in a container to make it easier for anyone to consume. Neo guided us to consider an AWS workspace instead. That’s now working and we are next adding other tools to the workspace.
Kaitlin Bleich

Kaitlin Bleich

Very knowlegeable and eager to help. After looking through our system he made good suggestions on immediate fixes and gave suggestions on future improvements. He also had me double check what he built before calling the project done, so I really appreciate how thorough and honest he is.

Rambunct Enhances Real-Time Healthcare Platform with Amazon API Gateway for ChargeHealth

ChargeHealth, in partnership with Rambunct, modernized its healthcare SaaS platform by implementing a serverless API-driven architecture powered by Amazon API Gateway. The solution enabled secure and low-latency access to healthcare data and workflows, integrating directly with AWS Lambda, DynamoDB, and EventBridge. Rambunct optimized Lambda concurrency to reduce cold starts, applied API Gateway throttling and caching policies to stabilize response times, and deployed CloudWatch and X-Ray for real-time monitoring. This transformation delivered a 75% reduction in cold starts, 60% faster response times, and 40% cost optimization, while ensuring 99.9% uptime and HIPAA compliance—empowering ChargeHealth to deliver reliable, scalable, and compliant healthcare recognition services.
