I need a simple Power Apps form that walks a user through a checklist of fewer than twenty questions. The list mixes Text input, Multiple choice, and Yes/No fields, so the control types must switch cleanly as the user moves down the form. Only the Text input questions should reference history. For those, I want the most recent submitted value to appear next to the field where the new answer needs to be submitted, giving users an at-a-glance reminder of what they entered last time without overwriting the editable box. The finished app has to save each run as a new record while still being able to pull the prior value for the relevant text fields when the same user—or any user, if that is easier—opens the checklist again. As long as the experience looks tidy on desktop and mobi...
I need to setup a clean, reliable way to push every new or updated contact from BatchLead straight into HubSpot, carrying over the full contact profile—name, email, phone, address, tags, notes, everything the BatchLead API exposes. My only goal right now is accurate one-way synchronization; automated lead scoring or task management can wait until later versions. Here’s what success looks like to me: • A small middleware script, custom app, or Zapier/Make scenario that watches BatchLead and creates or updates the matching contact in HubSpot in real time (or near real time). • All standard and custom fields mapped correctly so no data is lost. • Duplicate prevention based on email or another unique field. • Simple setup instructions plus a brief README ...
I’m ready to move our entire sales database from Monday CRM into HubSpot so our team can run all sales-management activities in one place. The data set is broad: contacts, deals and tasks are the core, but I also need every linked location, phone number, lead record, call log and text history brought over without losing relationships or timeline details. Here’s what I’m expecting: • An audit of the current Monday boards so each field is mapped to its proper HubSpot object. This will also require cleaning up the data in Monday to make it ready to export. • A clean migration (test, full run, final verification) carried out with HubSpot’s import tools, API or a trusted third-party connector—whatever you’re most confident with. • Post-migrat...
I need a complete data-warehouse solution for Dual Specialist Hospital (Medicare) in the United States. The core objective is to pull our patient health records into a single, well-structured repository and make that information immediately useful for data analytics and reporting. Clinical staff, quality-improvement teams, and executives all expect fast insight without wading through multiple systems or static spreadsheets. The build must support: • Real-time data analysis so new encounters, labs, and vitals are visible in minutes, not days. • Customizable reporting templates our analysts can adjust without developer help. • Data visualization tools that present trends clearly for non-technical decision-makers. I’m open to the platform you recommend—wheth...
We are looking for an experienced KNIME developer to build and test a structured KNIME workflow based on an already-defined process and workflow diagram. The workflow will: read specific worksheets from one Excel workbook; validate and filter project/bidder data; scan a folder structure containing bidder working files; identify and classify files based on filename/path rules; group and pivot the results; join the folder-scan results with the Excel register; apply deterministic readiness rules; produce a final multi-sheet Excel output report. The workflow must handle 1 to 10 bidders dynamically, without fixed branches for each bidder. We will provide: the workflow logic and block diagram; a detailed build guidance document; a populated Excel test workbook; sample folder/file structures...
I have a batch of business letters that must look polished and consistent in Microsoft Word. Each letter needs clear, well-aligned tables or simple charts embedded in the body, and a fully working mail-merge setup that pulls recipient data from an Excel sheet. Here is what I expect at the end: • A reusable Word template styled for formal letters (English and Hindi text will appear, so keep fonts and spacing bilingual-friendly). • Tables or charts formatted to match the template’s style, without breaking alignment when the data changes. • Mail-merge fields correctly mapped to my Excel list so I can generate all letters with one click. • Clean, error-free files returned in both .docx and PDF, ready to print or email. You are free to streamline the workfl...
FIrst of all: German-speaking freelancers are clearly preferred! I want my existing ThingsBoard instance to trigger a wind alarm based on a clearly defined wind speed threshold. If this threshold is exceeded, the platform must immediately send an email and/or SMS notification to the contacts I specify. The scope focuses on three points: 1. Create the rule chain (or customize the existing one) so that the device’s wind speed data is evaluated based on a configurable threshold. 2. Create the alarm definition for a specified threshold and link it to the rule chain. 3. It must be possible to specify a wait time (for example, one hour) before the next alarm is triggered. Exception: The measured value is higher than the previously measured value! 4. The email and text message must c...
I’m looking to turn our commercial-excellence vision into a working MVP that every member of the sales organization can open, understand, and act on. The core of the job is a web-based dashboard that plugs directly into our CRM, ERP, and Datalake, consolidating those feeds into one clear view. What the dashboard must do • Display real-time performance metrics so managers and reps immediately see where they stand against target. • Generate an automatically refreshed list of priority actions for each user, guiding day-to-day execution. • Show concise integration status indicators so everyone can trust the underlying data at a glance. User scope Both managers and sales representatives will use the same interface, so role-based filtering or permission logic will be n...

I have several digital files that need to be brought together in a single, well-organized Excel workbook. Your task is to enter the data accurately, structure it into clear tables, and then build insightful line charts that highlight the most important trends in the dataset. Here’s what I need from you: • A tidy Excel workbook containing all imported data arranged in logical tables. • A set of line charts—one for each key dataset—linked to those tables so that updates flow automatically. • Brief summary tables beneath each chart, showing the figures that drive the visuals. Accuracy is critical, and the final file should be easy for me to maintain and update without breaking any references. If you’re comfortable handling digital source files and ...

Hi I will share the details with the shortlisted candidates. Thanks
Project Name: Build a Microsoft Teams Search Bot ## 1. Project Overview I want to create a simple chatbot for my company's Microsoft Teams. When a staff member types an IP address or a Computer Name (Hostname) into the chat, the bot should automatically look it up in an Excel spreadsheet and reply with the details of that asset (like who owns it or its location). To keep our company data safe, I will not give the developer access to my system, and I do not want to import pre-made files. Instead, the developer will guide me over a live video call (like Zoom or Teams) while I share my screen, showing me exactly where to click on my laptop to build the bot myself. ## 2. Tools We Will Use We will use standard Microsoft tools that are already built into our company account: * Microsoft T...
I need a clean, well-documented Python script that connects to my existing MySQL database and inserts new records reliably. The script should: • Establish a secure connection to my MySQL instance (local credentials or .env file—your call as long as passwords stay out of the code). • Accept data passed in as variables, JSON, or a small CSV—whichever is easiest to parameterise—then build the corresponding INSERT statements. • Handle common edge cases gracefully (duplicate keys, NULL values, connection drops) and log any failed rows for review. • Be easy for me to run from the command line or drop into a larger workflow later. Please write with standard libraries plus mysql-connector-python or PyMySQL; SQLAlchemy is fine if you prefer. Include a b...
I want to introduce an IoT-driven inventory management system into my single-location car body shop so I can serve customers faster and with fewer stock-outs. The whole point is efficiency: when a repair order comes in, I need to know instantly whether the right panels, paints, fillers and fast-moving consumables are on hand and, if not, receive an alert before the customer even finishes the intake process. Here is how I picture it working. Every item shelf, paint cabinet and parts bin is fitted with a sensor solution—RFID, weight sensors or another technology you recommend—that feeds live counts to a cloud dashboard. When counts dip below a preset threshold, the system suggests a purchase order or flags it on a tablet that my front-desk staff already uses. Because the goal is...
Developer Brief Build a secure, cloud-based sports performance data platform that consolidates data from multiple technology providers into one dashboard. This is an example dashboard I have built The initial scope is to integrate Catapult Sports, VALD, and Teamworks. The platform must support both API-based data ingestion and manual or automated uploads of Excel/CSV files. API connections should retrieve approved data on a scheduled basis, while spreadsheet imports should validate, map, and standardise fields before storage. Create a central database with a consistent athlete profile and identifiers, enabling data to be matched across systems. Athlete matching should prioritise unique IDs and verified email addresses, with an administrator review process for unmatched or duplicate rec...
I run a small roofing company and I am moving our workflow into Quote IQ. I need someone who already knows the platform—and Stripe—to get everything connected and looking right the first time. Here is what I am trying to accomplish: • Import the data I already have (mainly the Stripe-related customer and payment details I exported) so it shows up correctly inside Quote IQ. • Complete the initial Stripe account setup, then configure it inside Quote IQ so new quotes can be paid online without errors. • Resize and upload our existing logo files so they display crisply on web and PDF quotes. Please let me know about your experience with Quote IQ, Stripe dashboards, and basic graphic resizing, as well as an estimated timeframe to get all three points finished....
I’m building the first release of my stock-trading platform, “Trade for Tomorrow,” and the immediate priority is to wire in reliable, ultra-low-latency market data for both the NYSE and NASDAQ. Here’s the scope: • Connect to a proven real-time data provider (Polygon, IEX Cloud, Alpha Vantage, or your recommended alternative). • Stream level-1 quotes, trade ticks, and basic fundamentals with sub-second refresh. • Expose the feed through a clean, well-documented REST or WebSocket API so the rest of my application can subscribe and render charts instantly. • Include simple throttling, reconnect logic, and error handling so the service stays resilient during high-volume sessions. • Hand off a lightweight dashboard or sample script (...

I need an experienced Siemens SIMATIC PCS 7 / WinCC engineer to build a read-only connector from an existing PCS 7 DCS system to an existing Excel MIS workbook. The plant already uses PCS 7/WinCC and the Excel workbook already contains formulas and a management dashboard. The goal is to automatically extract selected DCS values and populate only the approved Excel input cells without modifying plant-control logic.

For this project I need customer information that is currently scattered across several files merged, de-duplicated, and polished inside one master Excel or Google Sheets workbook. Once the sheet is tidy, every contact detail—name, phone, email, and address—has to be cross-checked against reliable web sources to make sure the data is accurate and up to date. When the verification step is done, the final workbook must follow my formatting guidelines (column order, header style, conditional colour coding). I will share a short style guide and a small sample so you can mirror the look and feel exactly. Deliverables • Cleaned and consolidated customer-info spreadsheet • Column-by-column log of any corrections made, including URLs or screenshots that confirm each u...
My priority is to build and refine Microsoft Dynamics 365 Business Central through new AL objects, with the spotlight on custom tables and pages. These pages must support clean data entry, run their own validation, trigger custom workflows, and surface key metrics in dashboard-style reports. Beyond the UI layer, I need business logic that enforces bespoke validation rules and handles data integration processes so information moves reliably between internal modules and any external systems we connect later. Additional work will include, when required, adjusting RDLC or Word layouts for reports, extending posting and approval workflows, exposing data through APIs or web services, and tuning SQL for performance. Deliverables • AL code for tables, pages, and supporting codeunit...

I’m putting together a showcase-worthy sales workbook for my Data Entry & Excel portfolio and need an expert touch. The dataset is retail-focused and will be a mix of records I supply and additional, realistic entries you create to round it out. Everything must live in a single Excel file and look clean, consistent, and professional.
