I need the official open-source Java backed of our project deployed, configured, and ready for continuous delivery. The source code is stable; what’s missing is a production-grade environment that handles build, test, and roll-out with minimal manual touch points. Here is the flow I have in mind: 1. Hybrid database approach Distributed Cluster (3 VPS server) 2. Containerize the application with Docker and automate builds via Maven or Gradle. 3. Primary Databases for Chat History Cassandra (NoSQL) 4. Secondary Databases PostgreSQL (for users Metadata) on the codebase’s data model. 5. Redis : Presence/Session 6. Backed Language: Spring Boot Java 21/25 with RabbitMQ,and Maven or Gradle configuratio 7. Real-time: WebSockets for bidirectional communication 8. also preferred ...

I’m building an internal control panel that streamlines our customer-support workflow. The stack is Python with Streamlit for the UI, Redis for fast in-memory state and queueing, and Postgres as the source of truth for historical data. Core workflow The panel’s single purpose is to let our support team handle live customer interactions from one place. Agents must be able to launch or join an active chat, see who is waiting, review basic customer context pulled from Postgres, and hand the conversation off or close it. All updates to chat status should push instantly to every connected agent, so WebSocket or Streamlit’s native realtime features will be necessary. Key feature set • Live chat integration that plugs into our existing WebSocket gateway (or a lightwei...

SCOPE AND ARCHITECTURE ADHERENCE The published technical requirements and stack (Python, PostgreSQL as source of truth, Redis for locking, Binance integration, Docker deployment) are the priority baseline for this project. If you propose architectural changes (e.g., different database, alternative execution model, third-party services, or different infrastructure), you must provide clear technical justification explaining: • Why the change improves robustness or reliability • How it preserves deterministic state and idempotency • What trade-offs are introduced • Why it is superior to the baseline stack "Unjustified stack substitutions or generic alternatives will not be considered" OPTION A – Hybrid (Binance + 3Commas) Senior Python Engineer &ndas...

I’m running a Laravel 10 bulk-media sender that talks to WhatsApp Business Cloud through a webhook. Whenever the API answers with HTTP 429, the webhook does mark the message as failed, yet the queued retry flow (RetryFailedWhatsAppJob on Redis/cloud queue) rarely fires, and when it does, the image-ID matching logic sometimes mis-aligns. The result is missed retries or, worse, duplicate sends. Here’s what needs to happen: • Repair the webhook callback so the media object returned by WhatsApp is always matched to the correct outbound record. • Ensure the job is dispatched, picked up, and processed on the existing Redis-backed queue every time a 429 occurs, honouring the current attempt counter. • Implement a reliable back-off for those 429 responses so we r...

Please read carefully before bidding. We are building a production-grade AI-powered building inspection report platform. 90% was built in base44 however, base44 cannot parse pdf"s larger than 10MB, so we have hit a roadblock and decided to take another route. This is NOT: *A WordPress job *A Shopify job *A bubble/no-code job *A “prompt engineering” job *A basic CRUD web app This is a serious backend architecture project involving: PDF parsing (11MB+ technical reports) AI defect extraction Structured data normalization Repair cost estimation logic Long-running job orchestration Background workers / queues Multi-user concurrency Production deployment architecture NOTE: Required Technical Stack (Non-Negotiable) You must have experience with: Node.js or Py...

* This is for freelancers only, agencies stay away I need a Drupal specialist to build an institutional site whose primary role is to host and showcase educational content - specifically our research articles and publications. The platform must let visitors quickly locate material through robust search and filter tools tied to a clear taxonomy (author, topic, year, journal) and give them a one-click option to download individual papers as PDFs. Beyond the core article repository, I also want a dedicated area for larger research papers as well as a dynamic news & events section so we can highlight conferences, calls for papers, and awards. All content should be managed through Drupal’s editorial workflow with role-based permissions for authors, reviewers, and admins. Deliverabl...
