XML (eXtensible Markup Language) is a specialized language used for applications such as data exchange and web services, where structured communication is needed between legally, syntactically and semantically different systems. XML Developers are those with an in-depth understanding of the language and all its technical aspects. With an XML Developer, a client can structure their data, automate web service communication, optimize data analysis and transfer, format documents or integrate an XML API onto their system.

This isn't a simple "upload and save" task; we require a sophisticated streaming pipeline capable of processing massive datasets (CSV, XML, JSON) with minimal memory footprint and high reliability. Core Task Build a POST /imports/cars endpoint that: Automatic Format Detection: Handles multipart/form-data and identifies the file type (CSV, XML, or JSON) programmatically. Stream-Based Processing: Processes data using Node.js Streams / AsyncIterables. The application should never load the full file into RAM. Data Pipeline: Implements a clean ...
I need a single piece of software that controls my dimension-weight-scanning workflow from start to finish. The application must talk directly to three devices on the line—scale, volumetric camera and scanner—capture the dimension and weight data, then trigger a photo of the package label. From that image the program should reliably pull out the text, barcode and any QR code in one pass. Once each package is processed, all results have to be written to an XML file structured by date, with an auto-incremented package ID embedded in the node. The same data set should immediately feed two more actions: 1. Generate a ready-to-print shipping label (standard 4x6 thermal format). 2. Push the full XML payload to our in-house system through a REST-style API. I expect the software t...
I need an experienced Odoo specialist who can dive straight into customization work. My priority is tailoring three core modules—Sales, Inventory, and Accounting—to match our internal workflows without disrupting day-to-day operations. Key focus areas • Sales: streamline the quotation & order flow, refine stages, and align document templates with our branding. • Inventory: adapt multi-warehouse rules, automate replenishment settings, and fine-tune stock valuation views so staff see the data that matters. • Accounting: – Invoicing workflows: automate recurring invoices and approval checkpoints. – Reporting formats: redesign balance-sheet and P&L layouts for management reviews. – Tax computations: ensure local tax rules ar...

I need to turn an Excel sheet that holds status and transaction data into a single XML text file so my website can import it without complaints. The site expects very specific, custom tags, and I’ll share a sample file plus the exact tag map and hierarchy you must follow. Your task is to take the spreadsheet I provide and give me a repeatable way—VBA, Python, Power Query, or any approach you prefer—to generate a UTF-8 XML file that matches the structure perfectly. The converter must: • read every row of the sheet, • map columns to the custom tags I supply, • preserve dates, numbers, and special characters exactly as entered, • output a clean XML file ready for immediate website import. Deliverables I expect: 1. A working script, macro, or temp...
I need my Tally data presented through fully customised reports that look polished and calculate key figures on their own. Beyond the standard layouts, every report has to follow a precise page setup, column arrangement, headers, colours, and fonts that I will provide. Derived metrics—ratios, variances, running totals, margins—must populate automatically whenever the underlying vouchers change, so manual edits disappear entirely. You may work in pure TDL, TallyPrime’s built-in designer, ODBC links to Excel, or any blend that delivers a single-click refresh and lets me export to PDF and XLS without the formatting breaking. I’ll hand over a company backup, sample printouts, and a short style guide at kickoff, along with the exact calculation rules. Deliverables &bul...
I need an automation specialist who can take my existing business workflows and turn them into fully-functional, self-healing AI automations inside n8n. My preference for n8n is firm, but the flows will still draw on OpenAI APIs, webhook endpoints, and any necessary third-party integrations to close the loop. What I’m looking for • Translate each workflow step into a node-based n8n scenario, handling data entry, approvals, scheduling, and the sales-related logic that keeps our pipeline moving. • Architect reliable API calls (internal and external) and set up error-handling branches so failures are logged and retried automatically. • Optimise for speed and cost by choosing the right triggers, batching where possible, and trimming unused nodes. • Document eac...
The immediate milestone is to stand up a fully-functional DocuSign environment inside our C# / ASP.NET Core platform. Within that integration I need three things working seamlessly: • each template must pull the correct rates and monetary values into every field, • document workflows have to fire automatically from creation through signature, and • the whole flow must hook into our existing system endpoints without manual intervention. Because no formal documentation for those rates and values exists, you and I will map the data together, define the XML schema that will carry the information, and wire that schema to the DocuSign API. Once the DocuSign piece is solid we can move on to the wider XML-driven automation logic and, finally, a performance-oriented redesig...
I’m running an ItemsAdder-powered server that will soon update to 1.21.6, and I need the existing Java-edition resource pack brought over to Bedrock so that cross-play players see the exact same custom content. The job focuses only on the pack’s textures and 3D models; sounds are already handled. I’d like all work done inside Blockbench so that I can easily tweak or expand the assets later. Please keep the resolution, file structure, and naming consistent with the current Java pack, then rebuild whatever has to change for Bedrock’s JSON format and manifest. Optimizing polygon counts and texture size for Bedrock performance is essential, but visual fidelity must remain identical. Deliverables (acceptance criteria) • Bedrock-ready resource pack folder with , ...

My fertility charting app still works perfectly on older devices, but the current build targets an outdated SDK and refuses to install on phones running Android 10 and above. The goal is simple: update the codebase so it compiles cleanly in the latest stable Android Studio, installs without warnings on Android 10 → 16, and keeps every existing screen and feature exactly as they are today. What needs to happen • Raise the compile/target SDK level and migrate any deprecated APIs or support-library calls to AndroidX. • Update Gradle, dependencies and signing configs, ensuring 64-bit compliance and Play Store policy readiness. • Retain the present UI, workflows and data model—no new functionality or design overhaul is required. Performance optimisations are wel...
I am preparing to roll out electronic invoicing through ANAF’s e-Factura service and need a Romanian developer who has already been through the full API onboarding process. My immediate goal is to get the initial setup and configuration right the first time, so I’m looking for hands-on guidance rather than generic documentation links. Here is what I expect from our collaboration: • Walk me through the production and sandbox registration steps, including obtaining certificates, configuring OAuth2 authentication, and setting the required headers. • Provide a concise checklist of mandatory request/response fields so I can validate outgoing XML before it reaches ANAF. • Join a screen-sharing session to test one live invoice transmission and interpret the API r...

I have a Microsoft Excel workbook that holds company-filing data I prepare for Form 13F. I now need the entire sheet converted into a single XML file that satisfies every structural and tagging rule the SEC EDGAR system expects for a 13F upload. This means the output must load without errors in the EDGAR OnlineForms/TEST filing portal and reflect the exact schema, element order, attribute names, header information, and character-encoding standards set by the SEC. Key deliverables • EDGAR-compliant XML built from my spreadsheet • Successful validation log or screenshot from the SEC test filing system • A brief note explaining any assumptions or cell-to-tag mappings you applied I will provide the spreadsheet immediately and can answer schema questions quickly so we sta...

Preciso construir um backend de inteligência artificial que leia, de forma autônoma, PDFs técnicos recorrentes — o material chegará quase sempre como textos e áudios convertidos em documento — identifique tabelas complexas, texto descritivo e especificações técnicas, grave tudo em um banco SQL bem estruturado e, por fim, disponibilize essas informações em uma conversa no WhatsApp. O fluxo ideal é simples: envio o PDF, o serviço o processa, normaliza cada campo no banco relacional e, quando eu fizer perguntas no WhatsApp, recebo respostas claras extraídas desses mesmos dados. Essenciais para o projeto: • Extração fiel de tabelas, parágrafos e campos de especific...
Necesito desarrollar una aplicación nativa para Android cuyo núcleo sea un sistema de autenticación de usuario sólido y fácil de mantener. La primera versión debe permitir que un nuevo usuario se registre con correo y contraseña, inicie sesión, recupere credenciales y mantenga la sesión de forma persistente. Trabajo con Git, por lo que el código fuente debe entregarse en un repositorio privado y estar claramente documentado. Quiero una arquitectura limpia (idealmente MVVM o similar) y dependencias bien gestionadas con Gradle. Aprecio el uso de Jetpack Compose, aunque acepto XML si explicas tu elección. Acepto Firebase Authentication, Auth0 u otra solución siempre que justifiques la selección, p...
