...and I’m ready to take it live on AWS. The codebase is clean and sitting in a private Git repository; what I need now is an engineer who can handle the end-to-end deployment and leave me with a smooth, replicable workflow. Here’s the flow I’m imagining: spin up the right AWS services (EC2 or, if you think it’s smarter, Elastic Beanstalk or ECS), configure security groups, environment variables and SSL, hook the instance to our Git repo for zero-downtime updates, then connect the domain and verify that everything scales and logs correctly. If CloudFront or an RDS instance will help performance, let’s discuss—flexibility is fine as long as the final result is fast, secure and easy for me to maintain. Deliverables I’ll be looking for...

...updates (text, photos, or short videos), and interact through likes and comments. I have wireframe sketches that outline screen flow, but I’m counting on you for UI refinement, smooth navigation, and selecting the right tech stack—Kotlin or Java on Android Studio is fine as long as the final build is stable and future-proof. Robust back-end thinking is important too; whether you prefer Firebase, AWS Amplify, or another scalable service, please outline how you’ll handle user authentication, real-time feed updates, and media storage. To keep us focused, here’s what I expect at each milestone: • Interactive prototype to validate UI/UX • MVP APK with core social features functioning end-to-end • Final release build plus full, well-commente...

...media features, free wellness video content, and a professional search engine for users to connect with trainers and wellness professionals. The mobile application is built using React Native, while the backend services are developed using NestJS and AWS cloud infrastructure. The platform was originally built using AWS Lambda (serverless architecture), but due to performance limitations, cold start latency, and stability issues, the application experienced delays in launch readiness. We are now migrating the backend architecture from AWS Lambda to AWS EC2-based services to ensure better performance, reliability, and scalability for production. The project also requires debugging and fixing issues in the existing React Native mobile application, ...

Agentic Models are the single most critical area for us, though exp...

... The system has to ingest GPS data from roughly 300 buses every 10 seconds, which works out to about 2.5 million write events each day, so resilience and low-latency processing are critical. Platform & core stack • Cloud: we’ll build everything on AWS (EC2/ECS/EKS, VPC, IAM, S3, Route 53 ‑ whatever fits best). • Messaging: Redis is my first choice for the real-time pub/sub layer, though I’m open to Kafka if you can justify the trade-offs. • Monitoring: Prometheus for metrics, with dashboards in Grafana; CloudWatch can complement for AWS-native alerts and logs. Key things I expect you to deliver • A fully scripted, infrastructure-as-code deployment (Terraform or CloudFormation) spanning networking, autoscaling groups, security...

I’m looking for someone who can jump into my AWS account, create or adjust a single S3 bucket so it remains private, and configure it specifically for media storage. Once the bucket is in place, I need direct URLs that already include the necessary security controls—no presigned links that expire, just permanent links that can only be accessed as intended (for example, through a signed CloudFront distribution or an Origin-Access-Control setup). Here’s what I expect at completion: • A correctly-configured S3 bucket with private access policies and minimal public exposure • The IAM roles or policies required for my application to upload and retrieve files programmatically • At least one working, secure URL that proves the configuration works &bu...

...the front-end lobby, and I need a senior full-stack developer who can own the build end-to-end. The back end must be modular—micro-service friendly, containerised, and ready to plug in third-party game providers, odds feeds, KYC tools, and multiple payment gateways. A modern stack such as Node.js or Go for the services, TypeScript/React (or similar) for the client, and a cloud environment like AWS or GCP with Docker/Kubernetes for orchestration is preferred, but I’m open to your proven alternatives if they shorten time-to-market without sacrificing reliability. On the front end I expect a responsive, themeable lobby that can be reskinned for future white-label partners, plus a secure account area covering wallet, transaction history, responsible-gaming settings, and...

...searchable history—delivered as a responsive web app (React, Vue or similar is fine) backed by a secure, scalable API. Authentication must support email/password and OAuth (Google at minimum), messages need to store safely (PostgreSQL or MongoDB), and WebSocket-style live updates should keep the UI snappy without constant polling. Please containerise the stack with Docker so I can deploy easily to AWS or DigitalOcean. Down the road I may add file-sharing and task-management modules, so design the architecture with clear, documented endpoints and modular front-end components. For this phase your deliverables are: • Source code in a private Git repo • A running demo link or Docker compose file proving “one-command” spin-up • Brief setup &...

My production WordPress site running on AWS has suddenly gone offline and I need it restored to its last stable state as quickly as possible. The incident presents itself as a full website crash, so visitors currently see either a blank page or an error message. The stack is a typical EC2 + RDS (MariaDB) setup behind an Application Load Balancer, with nightly EBS snapshots enabled and AWS Backup configured—yet I have not confirmed which recovery point will be safest to use. I need someone who can immediately jump in, locate the most recent valid snapshot or other backup, perform the rollback, and verify that the site loads normally over HTTPS once complete. A successful engagement will: • Restore the site so pages, media files, and database content appear e...

I accidentally altered my live WordPress site running on an AWS stack and now both the layout and core functions are broken. The changes span theme tweaks, several plugin updates/installs, and direct content edits. Unfortunately, I do not have a usable backup to fall back on, so I need someone who can step in immediately, investigate the instance, and restore the site to its pre-change state. The site is hosted on AWS (EC2 + RDS + S3 for media). I can hand over SSH keys, AWS console access, and WordPress admin credentials the moment we start. Because no backup exists, I expect you to leverage any of the following, depending on what you find: EC2 snapshots, AWS AMIs, database point-in-time recovery, WP-CLI revisions, or manual code/database rollbacks. Your appro...

I already have a production-ready library management platform running on a front end with a NestJS API, containerised with Docker and deployed on AWS (files are stored on S3). The missing piece is a compact student-tracking module that: • scans a student’s unique QR code on entry and exit • records the exact timestamps, the library section they visit, and calculates total duration of stay • appears seamlessly inside the current interface (no separate UI) The work involves adding the relevant pages/components in , extending the NestJS services and database schema, wiring in any AWS resources you need, and shipping the whole thing with full Jest unit/integration tests. Code quality must match the existing clean, typed, linted codebase; every new co...
