    I have several Excel workbooks that track our income, expenses, proposals, and current billings. What I need now is a clear, lightweight finance dashboard that automatically pulls from those files and presents two headline numbers every time it opens: • Revenue to-date • Job conversion rate (proposals won versus proposals sent) A couple of simple trend and breakdown visuals around those figures (e.g., month-over-month revenue, conversion by job type) will round things out. Everything should refresh in one click, drawing only from the Excel data I supply today, but the structure should be open enough that I can plug in costs or profit-margin calculations later without a total rebuild.

    I’m commissioning a Total Cost of Ownership calculator as a native Windows desktop application. The tool should let me enter cost variables—capital expense, operating expense, depreciation periods, financing rates and any custom fields I choose—and instantly return per-year and lifetime TCO figures. Key features I must have: • Export to Excel so results, assumptions and underlying data tables drop cleanly into separate sheets. • Graphical analysis that auto-generates bar and line charts of annual spend, cumulative cash flow and break-even points inside the app. • Save and load calculations, storing multiple scenarios locally so I can reopen, compare and tweak them later.

    Project Overview I have an existing Excel workbook used for job costing in a construction/striping business. The workbook is already functional and calculates costs based on quantities entered across multiple sheets (organized by item types such as striping widths, colors, markers, removals, etc.). Each sheet calculates unit pricing based on quantity tiers and produces totals. However, my current summary sheet only shows category totals (e.g., total striping, total removals) and does not provide a detailed, itemized breakdown. What I Want to Achieve I need to create a final summary sheet that dynamically pulls and displays ONLY the items used in a job, including: Item description (ex: 4” White Stripe, RPM Marker, etc.) Quantity entered Unit cost (based on the pricing logic alrea...

    I have several gigabytes of raw complex I/Q captures taken across C, X, Ku, Ka and millimetre-wave bands, and I need the information hidden inside them extracted within a week. The job starts with demodulating the bursts, moves through full protocol reversing, and finishes with packet-level inspection that pinpoints the signal type, service provider and any network identifiers. Scope of work • Focus on satellite and MMWave waveforms—no vendor documentation is available. • Wireshark is the preferred environment for final packet dissection; use any supporting tools you like (GNU Radio, URH, inspectrum, etc.) along the way, provided the workflow remains reproducible. • Convert the raw I/Q into clean baseband, map the frame structure, decode the traffic and load it ...

    I need a skilled data professional to turn my historical sales records into reliable projections for the months ahead. The raw files are already exported from our POS and e-commerce platforms; they cover daily transactions, product categories, promotions, and regional outlets. Your first task will be to explore and clean this sales data, handle any missing values or outliers, and engineer features that capture seasonality, campaigns, and other business drivers. My primary goal is an accurate sales forecast and projection roadmap. I am particularly interested in machine-learning approaches—think gradient-boosted trees, LSTM, Prophet, or any other model you feel best suits the data’s structure. Classical time-series or regression techniques are fine as benchmarks, but the core d...

    I am working with a sizeable set of enterprise-level operational data and need a clear, defensible forecast of upcoming trends. Everything will be handled in Excel—no BI suites or code this time—so the entire workflow, from cleaning through modelling to final visualisation, must live inside a well-structured workbook. The primary scope centres on our operational metrics, yet the approach should remain flexible enough that I can later slot in sales or customer figures without re-engineering the model. Accuracy and transparency are critical: every assumption, formula, and transformation step must be traceable so managers can audit the logic. Key deliverables • A master Excel workbook containing raw data staging, cleaned tables, forecasting model, and dynamic charts &bu...

The template must auto-calculate all outputs from a small set of input cells, be formatted with the client's logo and brand colours, and produce a clean customer-facing layout that a sales team can use per deal without any Excel knowledge.

    I need a seasoned Power BI developer to turn a very large, highly-granular data set into a single, dynamic dashboard focused on monitoring key operational-efficiency KPIs. Here’s the landscape you will step into: our raw information sits in both SQL databases and a series of regularly exported Excel/CSV files. I want a model that connects to each source, transforms the data so that it’s truly analysis-ready, and then visualises the metrics that matter—cycle times, throughput, bottleneck alerts, utilisation rates and any supporting drill-downs we decide to add. Scope of work • Build or optimise the data model, including merge logic between SQL and CSV tables, DAX measures, and relationships that guarantee a fast, responsive user experience even when the data vol...

    I need a visually striking infographic that translates my label-design data into an easy-to-grasp story. The piece is strictly for data presentation, so clarity, logical flow, and accurate visualisation trump marketing flair. I will hand over the raw figures, colour palette, logo files, plus reference layouts; you’ll turn them into a single, polished graphic that works on screen and in print. Preferred tools are Adobe Illustrator or InDesign—feel free to bring Figma or similar into the mix if that speeds things up—but the final artwork must arrive in layered .AI as well as press-ready PDF and web-optimised PNG. Deliverables: • One complete infographic (landscape A4 or US-Letter, vector based) • Source file with editable layers and linked fonts • Pr...
