You will get a microservices based secure file storage cloud system
Project details
This project is a private cloud system of an organization in which users of that organization can store their files in the allocated space. The special thing about this project is that each file that is stored in the cloud will be encrypted and nobody can read the file even if it was hacked. The file will encrypt during the uploading and decrypt while downloading from the provided download link. There is no other point from which the user can decrypt the file.

I could only work with Hamza for a week before his availability changed due to unexpected reasons. I wish Hamza all the best.

I've built and architected systems that serve millions of concurrent users. That kind of scale forces you to think differently — every design decision has a cost, and shortcuts that work fine at a thousand users quietly collapse at a million. High throughput, low latency, and horizontal scalability aren't things I've just read about; they're constraints I've had to engineer around in production.
On the architecture side, I specialize in distributed systems and event-driven microservices. I've designed and led implementations of SAGA-based architectures to handle complex, multi-step business transactions across services — making sure data stays consistent even when things go wrong. Kafka sits at the center of a lot of my work: from real-time event streaming pipelines to decoupled service communication patterns that actually scale.
My backend roots are deep in the Java ecosystem. Spring Boot, Spring Cloud, and JPA are second nature. I've built everything from high-throughput REST and GraphQL APIs to resilient microservice meshes with circuit breakers, distributed tracing, and centralized config management. For cloud infrastructure, I rely heavily on AWS — ECS, Lambda, RDS, SQS, API Gateway — and I know how to design for reliability and cost from day one.
I don't just work in the backend, though. I've spent years building front-end applications in React and Vue.js that people actually enjoy using — clean interfaces, solid state management, and tight integration with the APIs behind them. I'm comfortable going full stack when the project calls for it, and I think that context makes me a better architect because I understand both ends of the system.
On the Python and Node.js side, I still take on work where it fits — Django backends, Express services, lightweight automation scripts — whatever gets the job done well.
What I care most about is building things that last. Clean boundaries between services, clear contracts between teams, systems that are easy to reason about six months after launch. If you have a complex system to build, an existing architecture to untangle, or a team that needs technical leadership, I'd genuinely enjoy working through it with you.
