    I want an original, impressionistic landscape rendered in acrylic on canvas to hang in my bedroom. The finished piece should convey the loose, evocative brushwork of classic impressionism rather than detailed realism, and it needs to complement a quiet, restful space. It would optimally look out a window (window frame shown in painting) at a wide river landscape (house is on the James River in Virginia). It should be 40 to 53 inches tall and 50 to 65 inches wide. If 40 x 60 standard is easier, that’s fine. The wall behind it is a dark blue. If you take on the commission, here is the flow I have in mind: • Share a quick sketch or digital mock-up so we can agree on composition, palette, and possible framing (plain light wood minimalist). • Provide a few progress p...

    I need an engineer who has spent at least five years building production software with both .NET Framework and .NET Core. The stack you will step into combines C#, ASP.NET Web API, Entity Framework and SQL Server on the backend, served through RESTful endpoints and a growing set of microservices. The frontend is split between Angular and ReactJS, so confidence working in either framework—and switching when the codebase demands it—is essential. You will work fully remote but must overlap with Indian Standard Time for stand-ups and ad-hoc discussions. Strong verbal and written communication is therefore just as important as your coding skills, because you will often be the one making technical decisions independently. The first milestones include extending existing APIs,...

    I’m midway through building a Laravel-based application and need another set of expert hands on the back-end. The core framework is already in place; now I want to accelerate feature development, tighten up existing code, and make sure everything scales cleanly. You and I will collaborate through GitHub feature branches and pull requests. Typical tasks will include creating or refactoring RESTful APIs, improving Eloquent relationships, optimising queries, adding queue jobs, and firming up middleware for role-based access. Clean, PSR-12–compliant PHP and meaningful PHPUnit coverage matter to me just as much as shipping fast. You should be comfortable working autonomously, yet open to regular code reviews and brainstorming sessions on Slack or Zoom. If you have experienc...
