I am building a specialised web application for an import-export business and need an experienced full-stack developer who is comfortable in both Angular and Java. The core of the platform will be written in Java on the server side, exposing RESTful endpoints, while the client side must be a clean, responsive Angular interface that feels fast even when large data sets are moving through it. You should have at least four years of hands-on experience with: • Modern Angular (v10+) components, services and state management • Java (preferably 11+) with Spring Boot or a similar framework for rapid API development • Secure, token-based authentication and role management • Relational databases and basic schema design What I need from you: 1.

...local machine, but I now need a small tweak plus reliable deployment on my AWS account. The tweak: the script requires one additional feature that we’ll clarify together once you’ve reviewed the code. It should remain lightweight, keep the current logic intact, and follow the same coding style. The deployment: after the update, I want the script running on AWS—ideally as an EC2-hosted service or Lambda function, depending on what you find most efficient. The instance should auto-start on reboot and log to CloudWatch (or a similarly straightforward option) so I can monitor it without extra overhead. Deliverables (acceptance criteria) • Updated Python 3.x script with the new feature fully integrated and tested • AWS setup and ...

I’ll handle reviews and merges daily, so you’ll get feedback fast. If crafting clean, efficient React code—and making users happy through rock-solid UX—is in your wheelhouse, le...
...Multisite on AWS is suddenly showing “Error establishing a database connection.” I can log in and supply the database credentials, but beyond that I’m not sure if anything on the EC2 side was recently altered. The site is wired to a GitHub-based pipeline, so once the outage is resolved I need to keep that automated deployment flow intact. Here’s what I need from you: • Diagnose and restore the database connection so the network of sites loads normally. • Verify wp-config, security groups, DNS and any RDS or EC2 parameters tied to the failure. • Confirm the existing GitHub → AWS pipeline still pushes code successfully (or patch it if the fix requires changes). • Document the root cause and the steps you...

My Magento 2 store is already live on a single Nexcess PaaS environment, but every update still goes through a manual FTP-style process.
