    I’m moving my long-running OSCommerce store from v2.2 to OSCommerce v4 on a fresh Linode VPS that will upgrade the current server specs to those more in line with v4. The job breaks down into three main areas: • Full data migration – several hundred categories, hundreds (possibly thousands) of products with all images, plus our entire customer database. Standard fields must come across intact, and each product’s VAT flag needs to stay selectable so we can keep “VAT / No-VAT” pricing accurate in v4. • Custom feature carry-over – the live shop relies on a currency switcher, a lightbox gallery for product images, and an offline payment processing add-on. I need those three customisations rebuilt or matched with equivalent v4 modules so daily wo...

    My FreePBX server is already connected to a Twilio Elastic SIP Trunk using a Credential List. Zoiper extensions register without issue and the PJSIP endpoint for Twilio shows “Available,” yet every outbound attempt returns “All circuits are busy now.” Nothing at all appears inside the Twilio call logs, so the traffic never reaches their side. I suspect the PJSIP trunk settings are to blame, though the outbound route or some subtle SIP-signaling mismatch could also be involved. No recent changes have been made to the trunk configuration, so whatever is wrong has likely been there from the start. What I need from you • Trace and isolate the fault across the outbound route, PJSIP trunk, and SIP signaling (sngrep or tcpdump, Asterisk CLI, etc.). • Apply the ...

    I need an Trainer with at least five years of hands-on VMware ESXi experience to run a series of practical, online sessions for my team. The participants already work with virtualisation at an intermediate level, so I expect you to dive straight into real-world practices rather than introductory theory. The focus of the course must cover everything from a clean ESXi install and host configuration, through day-to-day virtual-machine and resource management, right up to advanced networking and security techniques. Even though the format is lecture-based, I still want each talk grounded in live demonstrations; we have a fully functional ESXi environment on-site that you can connect to remotely and showcase each step in real time. By the end of the engagement I should have: • A st...

    I already have a Windows-based .exe that simply wraps a Spring Boot jar; that jar contains virtually all of the middleware logic connecting my local system with an external service. What I need now is a developer who can transform that single-file setup into a fully-fledged, scalable server running in the cloud. Point to me note - i want that spring boot server working as it is same no chnages only chances main sevrer inside it and make sure jar works with that server same to same as they work with orignal ones You’ll receive: • the original Spring Boot jar (inside the exe) • my full assistance and domain knowledge whenever you need it Scope 1. Unpack or otherwise extract the jar so the project can be built, tested and version-controlled normally. 2. Refactor or re...

    I already have an AWS Health Imaging (AHI) datastore up and populated with DICOM studies. What’s missing is a clean, browser-based way to view those images. I want an OHIF viewer instance—hosted in my AWS account—that pulls directly from AHI and streams the images with no loss of performance or security. Key objectives • Deploy or configure OHIF (latest stable) inside AWS—an S3 + CloudFront static site or an EC2/Docker setup is fine as long as it scales and stays cost-effective. • Wire the viewer to AHI using the official APIs so that studies, series, and instances load seamlessly. No intermediary PACS; the images must come straight from the AHI datastore. • Handle IAM roles, tokens, and signed URL logic so access remains private yet friction-f...

    This project is an automated health tracking application developed using Python to monitor body temperature and detect anomalies in real-time. By bridging the gap between software and hardware prototyping, the system continuously reads live data streams from sensors via serial communication. The core Python backend processes this data, checks it against standard medical temperature thresholds, and instantly visualizes the live logs on a clean, custom graphical user interface (GUI) dashboard, making health tracking highly accessible and efficient. Key Highlights of the Project: Real-Time Processing: Uses Python's serial communication (pyserial) to fetch continuous live temperature data from hardware sensors. Instant Fever Alerts: Implements precise threshold logic to immediately fla...

    I am ready to launch a new voice service and need a fully verified USA-based SIP trunk that lets me place and receive both domestic and international calls. Monthly traffic will sit in the 1,000 – 10,000-minute range and the trunk must support several concurrent calls without choking, so adequate channel capacity is essential. Here is what I need from you: • Introduce or provision a reputable provider that can activate an account in my company’s name with all necessary KYC completed. • Ensure the trunk is enabled for two-way voice, CLI presentation, 911 compliance, and international reach. • Supply full connection details (SIP URI, username/password or IP auth, codec list) plus concise step-by-step setup instructions for popular soft-switches or an Aster...

    I accidentally wiped several important WhatsApp conversations from my Android phone, and since then WhatsApp has run its scheduled cloud backups to Google Drive multiple times. The deletions happened over a month ago, so the current backup no longer contains the chats I need. I want to know whether those earlier, overwritten messages can still be extracted—either from an older Google Drive snapshot, residual local *.crypt12* files, or any other forensic avenue—and, if so, to have the complete chat threads restored or at least exported in a readable format (TXT, PDF, or HTML). You should already be comfortable working with Android data recovery, ADB, WhatsApp key database decryption, and Google Drive backup parsing. If root access or a temporary unlock bootloader is required, ...

    Secure Odoo-Claude Integration

    I’m running a self-hosted Odoo v17 instance and I want it to speak with Claude in a strictly controlled, read-only fashion. The goal is for Claude to pull customer-relationship data, inventory figures and any other information needed to generate automated reports—nothing more, no write or admin rights at all. Security is paramount, so I’m open to whichever connection method (API, webhooks, or another highly secure approach you can justify) best keeps the data safe while remaining maintainable with future Odoo and Claude updates. You’ll need to map the relevant Odoo models, handle authentication, and make sure permission scopes remain locked to read-only. Deliverables should include: • A working integration module or middleware script fully installed on my s...

    S3 DICOM Online Viewer Setup

    My DICOM studies sit in a private Amazon S3 bucket and I want to stream them directly to a web browser for basic viewing only—no downloads to a local machine. A clean viewport that can open single- or multi-slice files and let me scroll through images is all that is required; annotations and advanced diagnostics can wait for a later phase. I am open to whichever tool you feel is fastest to configure—AWS’s own DICOM viewer, an OHIF deployment, or a Cornerstone build—as long as the solution keeps every .dcm object inside AWS and loads quickly over typical broadband. Leveraging CloudFront, presigned URLs, AWS Lambda, API Gateway, or the new AWS HealthImaging service is perfectly fine if it simplifies the pipeline and keeps costs reasonable. Deliverables • Depl...

    Fix VICIdial Login Failure

    After a sudden power cut the server came back up cleanly—Apache, MariaDB/MySQL, Asterisk and all VICIdial services report as running and phpMyAdmin shows the database online. Yet every agent now sees “Invalid Username/Password” on the campaign screen and the admin page just reloads when credentials are entered. Here is what I have already done: examined the Apache, MySQL, Asterisk and VICIdial logs for obvious errors, repaired and optimized the vicidial_users table, and confirmed the credentials being typed are correct. No browser-side tricks helped. We also do not have a usable database backup, so whatever fix you apply must leave the current data intact—no wipe-and-reinstall options are acceptable. I need you to: • Identify the exact point in the s...
