I want a seamless way to turn data stored in a custom Zoho Books module into a polished, ready-to-send PDF contract. The focus is one custom module—Client Contracts—and, for now, the only merge data I need pulled in is the Client Details field set. Here is what I need built: • Design a Zoho Writer template that fits our Client Contract layout. • Write a Deluge custom function that calls the Zoho Writer Merge API, injects the Client Details coming from the selected Client Contract record, and produces a PDF. • Add a custom button inside the Client Contracts module. On click, it should fetch the record, run the merge, then either download the file or attach it back to the record for quick emailing. • Keep the solution native to Zoho Books—no ex...

My production Flutter app is live on Android and iOS phones right now, but I need to push it much further so it also shines on tablets and a Windows desktop build. The next release must feel polished, run offline without hiccups, and bring serious value-add features that keep merchants and their customers engaged. Core scope • Offline-first architecture with local persistence and an auto-sync routine that silently pushes queued actions once connectivity returns. • A chat-style, rule-based onboarding that walks new merchants through business registration step by step, validating inputs on the fly. • Referral and rewards module focused on a wallet / credit balance. Every reward earned, spent, or expired must update instantly in the user’s local ledger and sync to ...

I need a meticulous manual tester to run full functional testing on my Windows-based desktop application. The build is stable but hasn’t yet been exercised outside the development team, so I’m looking for someone who can approach it with a fresh set of eyes, follow typical user flows, and uncover anything that could block a smooth release. You will install the latest installer on your own Windows machine, explore every feature, and record all behaviours that deviate from the expected results. Clear, reproducible steps and supporting screenshots or short screen recordings are vital so my developers can fix issues quickly. I’m particularly interested in edge-case scenarios—unexpected inputs, window resizing, simultaneous actions—that automated scripts may miss....

I need a small, self-contained Python solution that turns one or more HTML files into a single PDF while preserving the original layout and, most importantly, keeping every internal or external link fully clickable—especially links that point to other PDFs stored alongside the output file. The finished document must remain portable, so if the folder is moved to another machine the links still resolve correctly without hard-coded absolute paths. I am happy for you to choose whichever open-source Python library best fits the job—ReportLab, pdfkit/wkhtmltopdf, PyPDF2, or a hybrid approach—as long as it is free to use and can be installed easily with pip on Windows and Linux. Deliverables • A Python script (or minimal package) that accepts an input HTML file path and...

I already have access to the OpenClaw framework and now need the agent itself brought to life. Your job is to configure, deploy, and prove that the agent runs reliably inside the environment. Here is what I expect: • The agent boots and registers cleanly in OpenClaw on a fresh machine (Linux preferred). • Core behaviours are enabled exactly as they appear in the default OpenClaw documentation—no feature regressions. • A short README explains prerequisite packages, the build or install commands, and how to launch the agent in both dev and production modes. • A quick test script or command sequence shows the agent performing at least one task end-to-end so I can verify everything in minutes.

Main requirements: - Clean and modular script structure - Improved sniper quickscope timing - Configurable right-stick micro movement patterns (RX/RY) - Adjustable delays and values for easy tuning - Separate functions so modes...

I have a single malware command that was executed on my Windows machine before I wiped the system. I now need that same command run inside a fully isolated virtual machine so every stage can be captured, unpacked, and reviewed without risking any real hardware. I am primarily worried about credentials and logins, browser sessions and cookies, files and documents—really anything the attacker might have reached for. To answer that, I’m asking for a full hybrid analysis that blends static inspection of the PowerShell and Python payloads with live dynamic monitoring. Please instrument the VM, let the malware phone home if it must, watch the network traffic, intercept any staged downloads, and document each indicator of compromise. Deliverables: • A concise written report, in...

I need a robust, real-time scraping tool that monitors an accounting / legal / financial-services website and records every visitor’s key details the moment they arrive. This tool must work within and outside website both ways. That means, if I upload this script within website, it should start working. While if I enter a particular domain in the tool without loading script, it should start giving same results as if script is loaded. The script must capture: • IP address • Name, phone and email • The exact Google or other search engine search keyword that led the user to the site • The specific page URL they land on and continue to browse • Any sign-up or form-fill actions performed • Geolocation (city/region/PIN Code) and device type Once eac...

Hi everyone, my name is Kalin, founder of Vortyx AI. Over the past few years I’ve been running an SMMA focused on selling AI automation solutions to businesses. We successfully scaled the company to $480k in revenue and have now sold the business. I’m currently looking to join a UK-based agency in a role related to AI automations. I’m particularly interested in helping agencies implement, manage, and optimise AI systems for their clients — including handling customer communication, automation updates, system maintenance, and improving workflow efficiency. Ideally I’d like to work on a monthly paid role with a growing UK agency. I’m also very open to collaborating with younger agency owners ( 18-24) as I enjoy building and scaling things together.

I currently rely on a heavily-macroed Excel workbook that does everything for me: • generates offers and proforma invoices, • pulls customer-specific prices and discounts the moment I type a name, • emails the document straight from the file, • lets me search products from a single cell, and • archives every invoice to a separate sheet so I can browse past transactions with one click. The file runs acceptably on Windows and macOS, but Android is a dead end because VBA and macros are unsupported. I now want all of that logic—and any sensible improvements—wrapped into a proper application that runs smoothly on Windows, macOS, and Android. A web-based or other cross-platform approach sounds logical as long as performance feels native; I&rsquo...

I need a WhatsApp-based chatbot built and configured through the WATI platform. Its first job is simple but important: deliver automated replies that greet each person by name so every conversation feels human and immediate, even when I am offline. The flow logic, message templates, and WATI setup must all be ready for production, fully tested on a live WhatsApp Business number. I will provide the greeting copy and any brand assets you require; you handle the rest—from mapping triggers in WATI to deploying and confirming that the name-based personalisation pulls correctly from WhatsApp’s user data. While this initial scope is focused on automated replies, I chose WATI because it can later expand into customer support hand-offs or full order processing. Structure the bot s...

I have an existing Python script whose sole purpose is data extraction: it turns PDF documents into CSV files. Right now the results are incomplete and the code is a little fragile. I need it tightened up so every piece of data in each PDF is captured and written to a clean, well-structured CSV. What I already have • A working—but imperfect—Python script • Sample PDFs that show the range of layouts the tool must handle • A sample CSV that illustrates the column order I expect What needs to improve • Reliable parsing across multiple pages and varied table structures • Accurate capture of every field, not just the obvious text blocks • Clear, readable code with comments so future tweaks are simple • A straightforward command-line...

I need to get my application talking smoothly with a third-party service through a dedicated API connection—this is not a database link or a general network setup. The job is to configure the endpoints, handle authentication (token or key), and prove the link works with at least one successful request/response cycle. Deliverables • Clean, well-commented code or configuration that establishes the connection • A brief read-me explaining any environment variables and steps to replicate the call • Confirmation that the call returns the expected data (screen capture or log output is fine) If you’ve done quick REST or SOAP integrations before and can jump on a screen-share to walk me through final testing, that would be ideal.

I have three full years of trend data sitting in a single Excel workbook.
