Hi, This is Elias from Miami. I have gone through your project description and understand you’re looking to build a scalable backend architecture on AWS for your product. The goal is to create a robust system that can handle various loads and integrate effectively with other services. With over 10 years of experience in backend development and my expertise in AWS, MySQL, and microservices, I am confident I can help shape and build your project efficiently. I focus on creating scalable and secure solutions that meet business needs. To approach this project, I will start by analyzing your current requirements, designing a scalable architecture, and ensuring seamless API development. I can also implement infrastructure as code using Terraform to streamline deployments. I have a few questions to get a better understanding: Q1 – What specific services do you expect the backend to integrate with? Q2 – Are there particular user roles or permissions we need to consider? Q3 – What is your anticipated load, and do you have any scalability requirements in mind? Looking forward to hearing from you.

Good to see this project, I will deliver the architecture document, DynamoDB data model, Terraform templates, CI/CD pipeline, and monitoring guide — all tuned for 10k+ RPS on AWS. One key decision: pairing ECS Fargate with SQS for traffic spikes lets you absorb bursts without over-provisioning, while DynamoDB on-demand mode handles write surges gracefully and avoids capacity planning headaches early on. Questions: 1) Are you leaning toward microservices or a modular monolith at this stage? 2) What does the core domain look like — approximate entity count and read/write ratio? Looking forward to your response. Best regards, Kamran

@DeveloperStation

Hi there, I’ve built production-grade APIs with AWS for over 15 years, focusing on CI/CD, security, and observability. I’ve led multiple startups from MVP to successful acquisition, so I understand the importance of delivering a product that truly meets market needs. With AWS, I prefer using ECS for containerized workloads, as it’s more cost-effective than EKS and provides a simpler, more reliable CI/CD pipeline. I’ve also integrated OpenTelemetry and CloudWatch for proactive monitoring, ensuring we catch issues before they impact users. Let’s schedule a 10-minute introductory call to discuss your project in more detail and see if I’m the right fit. I usually respond within 10 minutes. I’m eager to learn more about your exciting project. Best, Adil

Hi there To build a production-grade API service that can sustain spiky traffic, the most critical part is making the architecture measurable from day one, not just scalable on paper. I’ll approach this by first defining the service boundaries, traffic assumptions, failure modes, and NoSQL access patterns before locking in ECS/EKS/Lambda, SQS, EventBridge, caching, and VPC/IAM structure. The NoSQL model needs to be driven by read/write behavior, hot partition risk, backup strategy, and future query growth, otherwise the API may look fast early but degrade under real load. This means I understand how to connect architecture, IaC, CI/CD, observability, security, and disaster recovery into one deployable AWS pattern. My process starts with the architecture and data model, then moves into Terraform/CDK templates and pipeline design, followed by monitoring, alerting, load-test guidance, and handoff documentation. If it aligns with you, let’s discuss in detail via private chat.

@Herculesz

Hi I can partner with you to design and build a production-grade AWS API service focused on scalability, reliability, security, and clean deployment automation. The main technical challenge is creating an architecture that can handle spiky 10k+ RPS traffic while keeping P95 latency low, avoiding single points of failure, and making failures easy to detect and recover from. I can help shape the backend architecture using AWS services such as ALB, ECS/EKS or Lambda, DynamoDB or another NoSQL store, SQS, EventBridge, ElastiCache, IAM, VPC design, and CloudWatch/OpenTelemetry observability. I can also design the NoSQL data model around real read/write access patterns, partition strategy, backups, replication, and disaster recovery. For delivery, I can prepare Terraform/CDK/CloudFormation templates, CI/CD pipeline definitions, automated testing, vulnerability scanning, and blue-green or rolling deployment patterns. The result will be a well-documented, deployable foundation with architecture diagrams, monitoring guidance, and clear handoff material for future growth. Thanks, Hercules

I’m excited about the possibility of collaborating on this project and look forward to discussing it further. Best, James

@ahmadpiran

Hey, Building for 10k+ RPS with sub-100ms P95 latency is not just an infrastructure decision, it is a data model and caching strategy decision from day one, and getting that wrong early means expensive rewrites later. I will design the full AWS architecture, propose a DynamoDB data model with access patterns and DR strategy, write Terraform IaC templates, set up a CI/CD pipeline with automated tests and zero-downtime deployments, wire in CloudWatch and OpenTelemetry observability, and walk you through every key decision in a recorded handoff session. I have designed and shipped production AWS backends on ECS and Lambda with DynamoDB at scale, using ALB, SQS, and EventBridge for fault isolation, and delivered Terraform stacks that deploy end-to-end in a single pipeline run. Before I finalize the architecture proposal, what does the core domain look like in terms of read vs write ratio and whether access patterns are primarily key-value lookups or involve complex querying, since that decides whether DynamoDB alone is enough or whether we need a secondary index strategy or an ElastiCache layer alongside it? Best, Ahmad

@codefusion53

Hi This is a strong architecture first project and I can help you design a system that scales cleanly while staying resilient under real world load. I will define a clear architecture based on your use case whether that leans toward a modular monolith for speed or microservices for long term scale, all aligned with AWS best practices. I will design a NoSQL data model optimized for your access patterns, implement infrastructure as code using Terraform or CDK, and set up a CI CD pipeline with automated testing, security checks, and zero downtime deployments. The system will include proper use of services like ECS or Lambda, API Gateway or ALB, DynamoDB, SQS, and caching layers to ensure performance at scale. Observability will be built in from day one with metrics, tracing, and alerting so issues are visible and recoverable quickly. You will receive complete documentation, diagrams, and a clear walkthrough to support ongoing development. Best, Justin
