Project: Armbrella – Fitness & Wellness Social Platform Armbrella is a mobile platform focused on fitness and wellness that combines health tracking tools, social media features, free wellness video content, and a professional search engine for users to connect with trainers and wellness professionals. The mobile application is built using React Native, while the backend services are developed using NestJS and AWS cloud infrastructure. The platform was originally built using AWS Lambda (serverless architecture), but due to performance limitations, cold start latency, and stability issues, the application experienced delays in launch readiness. We are now migrating the backend architecture from AWS Lambda to AWS EC2-based services to ensure better performance, reliability, and scalability for production. The project also requires debugging and fixing issues in the existing React Native mobile application, along with improving backend stability and API performance in the NestJS backend. Key Responsibilities • Review the existing React Native mobile application and NestJS backend codebase • Identify and fix bugs, crashes, and performance issues in the React Native app • Debug and improve NestJS backend APIs and services • Migrate backend services from AWS Lambda to EC2-based architecture • Optimize API performance, response time, and backend stability • Improve scalability and reliability of the backend infrastructure • Implement proper deployment, monitoring, and logging using AWS services • Ensure the platform is production-ready and stable before launch Core Platform Features • Health and wellness tracking tools • Free fitness and wellness video content • Social media-style fitness community • Search engine for trainers and wellness professionals • Mobile-first user experience through React Native Requirements • Strong experience with React Native mobile development • Strong experience with NestJS backend development • Experience working with AWS (Lambda, EC2, VPC, CloudWatch, S3, etc.) • Experience with serverless to EC2 architecture migration • Ability to debug complex mobile and backend issues • Experience improving API performance and application stability • Ability to deliver a stable, production-ready platform quickly Goal Deliver a fast, reliable, and scalable mobile application and backend infrastructure to support the official launch of the Armbrella fitness platform.

This looks like a great fit, I will review the existing Lambda architecture, identify what is causing the performance and stability issues, and deliver a migration plan with a clear recommendation on whether EC2, ECS, or a hybrid approach is the fastest path to a stable launch. Once approved, I will handle the full migration, bug fixes, and production setup with monitoring and logging via CloudWatch. Before recommending EC2 outright, I will check whether the issues stem from Lambda cold starts, memory limits, or timeout constraints. In some cases, provisioned concurrency or right-sizing the functions resolves the problems without the operational overhead of managing EC2 instances. Questions: 1) What language and framework is the current Lambda backend built with? 2) Are the performance issues specific to certain endpoints, or is it platform-wide? Send me a message and we can go over the details. Best regards, Kamran

For optimizing the Armbrella AWS back-end, would it be fine if I analyze the current architecture, propose a migration to AWS EC2 (or suggest an improved AWS structure), and outline a plan for enhanced performance and stability? So I believe by implementing a well-structured back-end on AWS EC2, we can ensure a fast, stable, and bug-free platform for the official launch of Armbrella, meeting the goal of delivering a reliable infrastructure. By the way, what are the current monitoring tools in place for the platform to ensure performance and stability post-migration?

I’ve worked on fitness and wellness apps where serverless setups caused latency and stability issues like you’re seeing. Usually, moving all services directly to EC2 isn’t enough—re-architecting parts with a hybrid approach (EC2 for steady workloads, Lambda for event-driven tasks) often works best for performance and scalability. I’d start by reviewing your current Lambda functions and infrastructure setups to identify bottlenecks and error sources. Are there specific Lambda functions or API calls that slow down or fail frequently? This info will guide whether full migration or a mixed architecture fits better. Also, setting up CloudWatch with detailed custom metrics and alarms is key to catching issues before launch. For deployment, using containerization with ECS or EKS can add flexibility and ease scaling compared to pure EC2 instances. If needed, I can share a lightweight proof-of-concept for a critical service migration first, so you see performance gains early. Ready to dive in and get your backend stable and fast for launch.

Hi, As per my understanding: You have a fitness and wellness social platform called Armbrella that includes health tracking tools, wellness video content, a social fitness community, and a search engine for trainers. The backend was previously built using AWS Lambda but performance and stability issues delayed the launch. You now need an experienced developer to review the existing infrastructure, resolve technical issues, and migrate or redesign the backend architecture (likely to AWS EC2 or an optimized AWS setup) to ensure the platform runs reliably and is production-ready for launch. Implementation approach: I will start with a technical audit of the current codebase, Lambda functions, and AWS infrastructure to identify bottlenecks and architectural limitations. Based on the findings, I will migrate services to AWS EC2 or design a hybrid architecture using EC2, load balancers, S3, and VPC for better control, performance, and scalability. I will also optimize backend services, fix existing bugs, and implement proper deployment pipelines, monitoring (CloudWatch), and logging. The goal will be a stable, scalable backend capable of supporting video content, social interactions, and real-time user activity without performance issues. A few quick questions: Which backend language/framework is currently used in the platform? Are the mobile apps already completed or still in development? Approximately how many Lambda functions and services are currently running?
