I may add PayPal or Stripe later, so structuring the checkout to accommodate additional gateways without a full rebuild will be a plus. Your work should cover theme setup (responsive, fast, and conversion-oriented), product and category architecture, shipping and tax configuration, security hardening, and any essential plugins. Once everything is live, a quick hand-off session or concise documentation will make sure I can manage routine updates myself.

I run a small construction company and want to build a long-term relationship with an external IT team that bills by the hour. My most pressing need is tightening our email defences, but you will also step in whenever we face issues with phone or computer security, malware, or any attempt at hacking. For email specifically, make sure your proposal shows how you will: • stop spam and phishing before it reaches our staff, • enable encrypted communications that are simple for non-technical users, • set up access controls and ongoing monitoring so we always know who touched what and when. Beyond email, outline the tools and processes you use to harden endpoints, secure mobile devices, and perform rapid incident response. A detailed project proposal explaining you...

The look and feel should be unapologetically colourful and vibrant—think bold palettes, lively imagery, and playful micro-interactions—yet still keep load times lean and the user journey clear. Responsive design, accessibility compliance, and SEO-friendly structure are must-haves. I’ll need clear hand-off documentation...

I have a Unitree Go2 and need it to navigate outdoors without manual input. The focus is straight-forward: build and integrate a ROS 2 solution that lets the robot plan, localise, and execute safe paths across natural terrain. You are free to leverage the Nav2 stack, slam_toolbox, or any other ROS 2 packages that suit the task, as long as the end result runs reliably on the Go2’s onboard computer and works with its existing sensors. Deliverables • ROS 2 workspace with all custom nodes, launch files, and parameter sets • Clear build & deployment instructions (README or tutorial video) so I can reproduce the behaviour on a fresh system • Short live demo or rosbag proving the robot can start, plan, and reach a goal point over outdoor ground (grass/gravel...

...many people. Nothing is uniform: skin tones, hand sizes, lighting, backgrounds, and even finger counts may vary. The goal is to turn this dataset into a practical analysis tool that can: • calculate the flexion/extension angle at every finger joint in each image • flag when a finger or phalanx is completely absent so that it can be recorded automatically I expect you will combine classical computer-vision preprocessing with a deep-learning model (PyTorch or TensorFlow are fine) and possibly leverage pose-estimation libraries such as MediaPipe or OpenCV for landmark detection. Accuracy matters more than perfection in lighting or background, so robust data-augmentation and domain-adaptation techniques will be key. Phase 1 Train and validate a model that ingests a...
