I’m expanding our engineering team and need a Qt-savvy C++ developer who is equally at home in QML. Your core mandate will be designing and implementing brand-new features rather than maintaining legacy code. The product you’ll touch is a Qt-based web service/web-server stack, so day-to-day work involves threading, asynchronous I/O, and crafting clean, well-documented REST API endpoints. You should feel comfortable moving between C++ business logic, the Qt networking layer, and QML UI components, keeping performance in mind while shipping user-visible functionality on a predictable rhythm. Experience profiling and unit-testing Qt projects is a plus, and if you have dabbled with WebSockets or GraphQL we can certainly put that to use later, but right now REST is king for us. Collaboration happens in Git and we track tasks in OpenProject; CI/CD runs on GitLab. I value readable, idiomatic code, clear commit messages, and proactive communication. If you like owning features end-to-end—from discussing UX nuances with product to watching your API calls hit production—let’s talk.

Hi, I understand you're building a Qt-based web service stack and want a Qt-savvy C++ developer who can design and ship new features end-to-end across C++ logic, Qt networking, and QML UI, with a focus on threading, asynchronous I/O, and clean REST endpoints. My approach is to start with close product alignment to pin UX and API details, then implement new features as modular Qt services with clear interfaces, using REST endpoints powered by QtNetwork components, careful threading (QThreadPool/QtConcurrent) and asynchronous patterns, and robust error handling. I will keep performance in mind while shipping user-visible functionality on a predictable cadence, and I will accompany code with readable docs and tests. I also emphasize profiling and lightweight unit tests for Qt projects, and I can contribute toward CI/CD workflows on GitLab and maintain open and transparent commits in OpenProject. If GraphQL or WebSockets come up later, I’ll be ready, but REST is our focus now. Which two to three REST endpoints should be prioritized first, and what are your target production performance metrics (latency, throughput, and error budget)? Best regards,

Hi I’m a senior C++ engineer with strong Qt and QML experience, building new features across Qt networking, async I/O, and RESTful services. The main technical challenge in a Qt-based web-server stack is keeping threading and asynchronous workflows predictable while delivering performant, user-facing APIs. I address this by designing clean service boundaries, using Qt’s event loop and concurrency primitives correctly, and profiling hot paths to avoid contention. I’m comfortable moving between C++ business logic, QML UI components, and the networking layer to ship features end-to-end with clear documentation. REST endpoints will be implemented with consistent schemas, validation, and error handling so clients remain stable as features evolve. I write testable, idiomatic Qt code, add unit tests where it matters, and use profiling tools to validate performance assumptions. I work smoothly with Git, GitLab CI/CD, and structured task flows, keeping commits readable and communication proactive. Thanks, Hercules
