Build Modern Applications with AWS Lambda
Automate, Scale, and Simplify with Event-Driven Serverless Architectures
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.

1. Event-Driven Architecture and Modular Design
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.
2. Real-Time Scalability and Concurrency Control
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.
3. CI/CD and Infrastructure as Code with AWS CDK
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.
4. Integrated Observability with CloudWatch and X-Ray
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.
5. Compliance-Aligned Security and Governance
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.

Michelle Beier
Everything I could have expected! very good communication, excellent work, great job understanding what I needed. Highly recommend.
Caleb Marcovich
Thanks to Rambunct, the client gained the ability to perform SQL queries from BI apps. The team was highly responsive, allowing them to manage the engagement efficiently. Their email communication was excellent. Overall, the project was successful.
Shahid Latif
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
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
Very knowledgeable 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.
Daniel Welsch
Rambunct has successfully set up and transferred the client's data securely. The team is quick to respond, constantly checked in, and delivers regular status updates. They maintain communication via virtual meetings, emails, and messages. Their fast, customer-centered service is remarkable.
Case Study
Rambunct Optimizes Chargehealth’s Real-Time Healthcare Platform with AWS Lambda
ChargeHealth, a healthcare SaaS platform, partnered with Rambunct to modernize its real-time reward processing system using AWS Lambda. The Rambunct team optimized concurrency settings, integrated Lambda functions with DynamoDB and EventBridge, and enabled fine-grained observability through CloudWatch and X-Ray. This transformation resulted in a 75% reduction in cold starts, 60% faster response times, and 40% cost savings—ensuring scalable, reliable performance for critical healthcare workflows accessed across thousands of facilities.
