...70,000 impressions. The infrastructure sits on AWS and comes with an extra $1,000 in unused cloud credits, so the buyer can scale immediately without new hosting costs. What I need from you is simple: bring serious, purchase-ready buyers to the table and guide the process through to a signed deal. Whether those buyers are individual investors, venture funds, or established tech companies makes no difference to me; I am open to any qualified acquirer. To help you sell the opportunity, focus on the three headline benefits that consistently catch interest: • Customisation and unique features that go far beyond the standard Codecanyon release • A current user base and genuine global reach already proven by live marketing data • $1,000 in AWS credits and ...

...app already designed for iOS and now need a specialist who can take it from my Xcode project to a live, smoothly running product in the App Store, then keep it healthy as user numbers grow. The current build focuses on secure user authentication—no product catalog or order processing yet—so the priority is to stand up a rock-solid sign-in flow, connect it to a reliable back-end (Firebase/Auth0/AWS Cognito, whichever you prefer and can justify), and comply with Apple’s guidelines on data privacy. Once the app is accepted, I’ll rely on you for versioning, TestFlight roll-outs, crash monitoring, and incremental updates generated by my AI design pipeline.

I need an experienced DevOps / Cloud engineer to move my existing Laravel application onto a highly available cloud stack. The current codebase is stable; what it lacks is true resilience. I am open to AWS, Google Cloud, or Azure—whichever you feel offers the most reliable combination of load balancing, fail-over, and data redundancy with the least operational friction. Here’s what I’d like from you: • Design an architecture diagram that illustrates a redundant web tier, stateless queue/worker strategy, and a managed database cluster. • Automate the build with IaC (Terraform or CloudFormation preferred) and CI/CD so every merge to main spins up identical environments. • Hand over clear run-books and monitoring hooks (CloudWatch, Stackdriver, or ...

My web application is ready to go; what’s missing is a clean, reliable deployment on AWS. I want the site running on standard-configured EC2 instances—no special hardware or exotic AMIs—inside a secure VPC. You’ll handle everything from spinning up the instance, installing the required runtime and web server, to pulling my code from GitHub (or a private repo I’ll grant access to) and exposing the app over HTTPS. Please configure security groups with the least-privilege approach, set up environment variables, and make sure logs are easy for me to access later. These AWS serviON: ✔ EC2 (1 instance) ✔ EBS ✔ S3 ✔ IAM ✔ CloudWatch (basic) When the work is done I expect: • A live, reachable HTTPS endpoint for the application • SSH...

...insights through Power BI, so once the model is validated I’ll ask you to craft intuitive dashboards that highlight drivers, confidence ranges and any red-flag anomalies the model detects. Solid statistical grounding is essential; I want clear explanations of feature importance, assumptions and limitations that business stakeholders can grasp quickly. Big-data exposure, cloud familiarity (Azure, AWS or GCP), ETL pipeline design and MLOps practices are all welcome extras—you’ll have room to propose improvements if they make the solution more robust or scalable. Deliverables I need from you: • A well-documented predictive model with reproducible code and clear version control • Cleaned and transformed datasets stored back into SQL (or a recommended a...

...maintenance right from our phones on both iOS and Android. Each form should include Yes/No checkboxes, a comment area, and the option to attach photos so we can quickly document issues like a leaky faucet or damaged flooring. Real-time sync is essential: when one of us completes or edits a checklist, everyone else must see the update instantly. I’d like the data stored in the cloud—Firebase, AWS Amplify, or a similarly reliable backend—so nothing sits only on a single device. A second core feature is tenant-initiated work orders. Every unit should have a unique, scannable QR code. When tenants scan it, they’re taken to a simple screen (or a pre-filled email template) where they can describe the problem, attach a photo, and hit Send; the submission ...
