I’m ready to roll out Odoo Enterprise on-prem but I would like an expert beside me for the actual installation step, what I need right now is someone who knows the quirks of the Enterprise build and the usual Python/odoo user setup to make sure the first launch goes smoothly. We’ll work together over a live screen-share (or, if you prefer, a concise step-by-step document followed by a quick Q&A call). By the end of the session Odoo should be running as a service, reachable from a browser, and ready for me to dive into further configuration on my own. Key points you should be comfortable with: • Installing Odoo Enterprise • Docker That’s the scope—straightforward and focused on the installation itself. If you’ve done this a dozen times already,...

I want a freelancer to finalize, harden, connect, and future-proof my existing local AI agent system on macOS so it becomes a real foundation platform for my long-term digital AI assistant.

My in-house development team built a fully functional ERP to manage our large-scale manufacturing and export operations, yet day-to-day use feels sluggish. Endpoints take too long to resolve, database queries lag, and occasional hiccups interrupt our workflow. I’m looking for an experienced developer who can dive into the existing codebase, pinpoint the bottlenecks, and leave me with a noticeably faster, error-free system—all within the next month. The core modules (inventory, B2B/B2C sales, manufacturing tracking, reporting, and everything in between) already work; the goal is to make them run smoothly. You’ll need to review the current architecture, container resource allocation, database design, and API interactions, then implement optimizations without disrupting liv...
I need a fully-async Python 3.11+ pipeline that turns a live phone call into a smooth, sub-2.5 s p50 conversational loop. Here’s the flow I have in mind: a Twilio SIP trunk delivers the RTP stream to a WebSocket bridge; LiveKit Agents SDK manages the media session; Deepgram Nova-3 handles streaming STT; the running transcript feeds Claude (with tool-use enabled); Claude’s text comes back out through ElevenLabs Flash v2.5 for TTS and streams to the caller in real time. What I need from you is a working reference implementation, instrumented and tuned so I can see latency at each hop and fine-tune Voice Activity Detection thresholds. The code must retry transient errors, log everything that matters, notify the caller gracefully on trouble, and, if the Sonnet tier fails mid-call...
I’m building a lightweight telehealth web app and need an experienced backend developer to set up the core services. The stack is fixed at Node.js for the server layer and PostgreSQL as the data store, so deep familiarity with Express (or a comparable framework), query builders/ORMs, and SQL optimisation is essential. Scope of this first phase is intentionally narrow—two key modules only: 1. Secure user authentication (email / password, bcrypt hashing, JWT sessions) 2. Payment workflow wired to either Stripe or Razorpay—single-charge flow with webhooks for confirmation and refunds The REST API should expose clean endpoints the front-end team can consume for sign-up/login, patient profiles, appointment booking, and payment intent creation. Please containerise the ...

I’m building a knowledge hub for developers and need clear, step-by-step tutorials that dig into intermediate-level features of popular programming tools—Visual Studio Code will be the first focus. Each guide should walk readers through advanced configuration, key extensions, and practical integrations, written first in fluent, engaging English and then rendered faithfully into Arabic. I will supply the high-level outline and any brand guidelines; you research, draft, and translate. Accuracy is paramount—commands, menu names, and code snippets must be tested so the instructions work exactly as shown. Friendly but concise language, plenty of screenshots, and callouts for common pitfalls are what I’m after. Deliverables for every topic: • Polished English artic...

I want a clean Ubuntu 24.04 (Debian-based) install turned into a central hub for the video coming from my Hiseeu NVR. The goal is simple: any time I click an icon or bookmark I should land on a web page that shows every camera live, lets me scrub back through stored footage, and works just as well from a desktop browser as it does on a phone. I’m not sure yet whether it makes more sense to repurpose an existing box or start from scratch, so I’ll lean on your advice there. The same goes for the NVR’s API or ONVIF capabilities—I may need you to confirm what is available and then wire it up. Deliverables • A fully configured Ubuntu 24.04 server (or guidance on fresh install vs. reuse) • Integration with the Hiseeu NVR so all camera streams record an...

Our custom construction ERP is in the final stretch. The core modules are in place, but three areas still block go-live: 1. Sales pipeline – Automation & workflows I have the UI and basic routes, yet deals do not progress automatically through stages, nor do the triggers for emails, task creation, and forecast updates fire reliably. I need you to hard-wire the logic in Node.js/Express and make sure the jQuery / Select2 front-end reflects every state change instantly. 2. PostgreSQL – Connection issues Under load the app occasionally drops connections and stalls. The schema relies on complex JOINs and several polymorphic associations, so I need a deep dive into pooling, transaction handling, and any rogue long-running queries that may starve connections. Fixes must ...
I’m building a production-grade backend that orchestrates multi-step LLM workflows and serves them through a FastAPI layer. The stack is Python first, so I need someone who is genuinely comfortable with advanced language features, clean architecture, and test-driven habits. Core scope • Design and implement LangGraph/LangChain pipelines that call both Claude and OpenAI models. • Shape a robust PostgreSQL schema from scratch and write the migration scripts to match. • Expose all functionality via FastAPI endpoints with proper async handling, input validation, and error management. • Handle PDF generation with ReportLab (or an equivalent you like) for final user-facing reports. Claude-specific responsibilities Prompt engineering Understanding tok...
Senior Forward-Deployed Software Engineer Needed to Finish Enterprise Intelligence Platform MVP (Python / FastAPI / Graph / Data Pipelines) ⸻ Project Overview I am building RealScore, a financial intelligence infrastructure platform designed for investigators, regulators, financial institutions, and government entities. The system ingests public records and financial intelligence data, resolves entities, constructs ownership relationships, and produces explainable risk outputs. The repository is already substantially built. The core architecture, services, pipelines, and UI are implemented and functional. The first core feature (entity search → ownership → sanctions exposure → explainable risk scoring) is approximately 70–80% complete. However, it needs a high-l...
