Our Esteemed Clients

Leverage AWS-Powered Lambda Solutions to Build Resilient Serverless Applications

At Rambunct, we help organizations modernize their digital infrastructure by implementing secure, scalable, event-driven architectures using AWS Lambda. Our team designs and deploys microservices that integrate with services like Amazon API Gateway, DynamoDB, EventBridge, SQS, and SNS to deliver asynchronous, fault-tolerant systems. In engagements like ChargeHealth, we reduced cold starts and improved real-time processing using concurrency tuning and auto-scaling. In hybrid scenarios like JoyfulHealth, Lambda seamlessly powered decoupled notification workflows triggered from ECS and EC2-based systems. Whether you’re building from the ground up or optimizing legacy platforms, Rambunct delivers Lambda solutions that are cost-effective, observable, and aligned with AWS best practices.

Serverless Application Solutions with AWS Lambda

AWS Lambda empowers businesses to build responsive, scalable, and event-driven applications without provisioning or managing servers. By abstracting infrastructure complexity, Lambda enables teams to focus on delivering core functionality while benefiting from automatic scaling, integrated fault tolerance, and millisecond billing. Whether used in real-time healthcare systems or decoupled notification pipelines, Lambda ensures performance, cost-efficiency, and agility.

At Rambunct, we specialize in designing production-ready serverless architectures using AWS Lambda. We leverage service integrations with API Gateway, DynamoDB, EventBridge, and SQS to build robust microservices and automation workflows. From latency-sensitive SaaS platforms like ChargeHealth to hybrid cloud systems like JoyfulHealth, we deliver Lambda-based solutions that are secure, observable, and aligned with AWS Well-Architected best practices.

We develop stateless, event-driven applications by leveraging Lambda’s native integrations with EventBridge, SQS, and SNS. This modular design enables clean separation of services, easy scalability, and reduced system coupling for resilient and adaptive workloads.

Our deployments use reserved and provisioned concurrency settings tailored to the customer’s needs. In ChargeHealth, this reduced cold start latency by 75 percent and ensured smooth function execution during peak traffic.

We automate serverless deployments using AWS CDK, enabling consistent infrastructure across dev, test, and production environments. CI/CD pipelines ensure seamless rollouts with change tracking and rollback support.

All functions include structured logging, tracing with AWS X-Ray, and custom CloudWatch dashboards. This observability layer provides actionable insights into performance bottlenecks, failure points, and invocation patterns.

Lambda deployments follow strict least privilege IAM policies and enforce encryption in transit and at rest. In healthcare engagements, Rambunct ensures HIPAA-aligned configurations by enabling audit logging, DLQs, and access controls.

Rambunct’s AWS Lambda Expertise

We harness the full power of AWS Lambda to deliver scalable, event-driven serverless solutions built for agility and resilience.

Scalable Serverless Compute Design

  • We implement Lambda-powered microservices with real-time responsiveness and no infrastructure overhead.

Event-Driven Workflows and Integrations

  • We use EventBridge, SQS, and SNS to trigger Lambda functions in response to domain events.

  • Enables loosely coupled, fault-tolerant communication between systems.

CI/CD and IaC for Lambda

  • Deployments are automated using AWS CDK and integrated CI/CD pipelines.

  • Supports safe rollbacks, staged deployments, and multi-environment consistency.

Security and Compliance Controls

  • Lambda roles are strictly scoped using IAM best practices and Access Analyzer.

  • Workloads are encrypted in transit and at rest, with compliance readiness for HIPAA workloads.

Performance Optimization and Cost Efficiency

  • Functions are tuned with provisioned concurrency, reducing cold starts by up to 75 percent.

  • We monitor usage patterns and right-size resources using CloudWatch and AWS Cost Explorer.

Monitoring, Tracing, and Alerting

  • CloudWatch and AWS X-Ray are used for end-to-end visibility into execution and performance.

  • Real-time alarms are configured for errors, latency spikes, and DLQ message volumes.

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.
