...simple analytics and user-level access control—all within an intuitive, modern interface. My priority is stability and long-term maintainability, so I’d like the codebase written in a widely supported language (C#, Java or Python with a robust GUI framework are all acceptable). A lightweight local database is fine for now, but the architecture should leave room for us to migrate to a cloud-hosted SQL solution later. Please include: • An installer or portable build that works out of the box • Source code with clear inline comments and a short setup/read-me file • Basic test data so I can see the key workflows in action If we move forward, I’ll share a detailed feature list and brand assets. For the proposal, give me a brief outline of the t...

...file. There might be a need to scrape data as well. Both the full address string and the explicit lat/long coordinates have to be preserved so I can map or geocode later. The ODB occasionally stores lookup tables in separate relations; bring those values across so the sheet is human-readable— no foreign-key IDs left unresolved. If you use any transformation scripts (Python, LibreOffice Base, SQL, Power Query, etc.) please hand those over as well; I may need to re-run the process when updated releases appear. If I decide to add extra columns later, I’ll let you know, so keep your workflow flexible enough to accommodate a quick re-extract.

...draft—everything handled end-to-end in one intuitive workflow. Once the season starts, fans and players need clean scoreboard views, standings, and push-notification highlights so they never miss first pitch. I will supply branding, rule book PDFs and basic wireframes; you bring the technical expertise to design, develop, test and deploy. A modern stack (React / Flutter, Node or similar, plus a scalable SQL or NoSQL back-end) is preferred, but I’m open as long as performance is rock solid and the codebase is maintainable. Deliverables • Responsive website and companion iOS + Android apps connected to a single back-end • Role-based user system (fan, player, manager, owner, admin) with secure authentication • Auction module for team sales, including...

...developer, or team, to build a multi-tenant logistics management system built on Angular 14 for the front-end, .NET Core for the API layer, and SQL Server as the data store. The one capability that must be solid from day one is Fleet management—vehicles, routes, and operational data must stay completely segregated per tenant while sharing the same codebase and database. Everything has to scale cleanly as new companies sign up, so tenant isolation, role-based access, and configurable settings are essential parts of the architecture. Core scope • Set up the tenant-aware user authentication/authorization flow (JWT or similar) • Design the SQL Server schema with row-level or schema-level isolation to keep each tenant’s fleet data separate &bul...

I maintain a legacy WinForms application built in Visual Studio with a SQL Server back-end, and I need a couple bug fixes and features improvements. Right now the pressing need is feature updates—specifically inside the business-logic layer. The job centers on adding new functionalities and refining several existing ones so the system continues to meet day-to-day requirements. You will dive into the C# codebase, work against our SQL schema, and push changes through our current Git workflow. Because the UI and database layers are stable for now, your focus stays on service classes, data access helpers, and any calculations that feed the forms. Deliverables I expect: • Updated business-logic code (C# / .NET Framework) checked in through client server • Clear i...

I need a new Cognos dashboard focused purely on data visualization. The dashboard will pull its figures from our existing SQL databases, so you’ll be working with relational data structures, writing efficient queries, and making sure refreshes stay fast even as record counts grow. The look and feel matter to me: clear charts, intuitive drill-downs, and a layout that lets managers grasp trends at a glance. If you have experience shaping Cognos visualizations with custom prompts, calculated fields, and conditional formatting, that’s exactly the skill set I’m after. Deliverables • A fully functional Cognos dashboard connected to the specified SQL sources • Reusable data modules and any query subjects you create • Brief setup notes so my int...

My donation-counter application (VB.NET, ASP.NET, SQL Server) currently treats the day as four 6-hour shifts. I need the underlying logic switched to three 8-hour shifts—nothing else about the feature set is changing and the screens can stay exactly as they are. Core work • Rework the scheduling code so every function that references shift boundaries now recognises 00:00-07:59, 08:00-15:59 and 16:00-23:59 (or equivalent server-time logic). • Update the existing SQL reports and any stored procedures that aggregate by shift so their totals align with the new 8-hour blocks. Acceptance I’ll verify by running a full day’s test data: the counters must roll over at the new cut-off times and all daily/shift reports must balance against those time...

...Build the Excel file so every chart, KPI card and slicer is driven by well-structured Pivot Tables, not hard-coded ranges. • Set up a companion Power BI report that mirrors the logic and lets me explore identical metrics there. • Give me a short screen-share walkthrough (recorded is fine) explaining the steps, so I can practise the process myself later; I’m keen to develop stronger skills in SQL, Python, Tableau and the main Python data-viz libraries, so please highlight where similar thinking would transfer to those tools. I’m a fresher, so clear explanations matter as much as polished deliverables. If you’ve helped newcomers before, mention it when you respond. A straightforward link to a sample Pivot-Table-driven dashboard or a live Power BI re...

I have an in-house VB.NET application backed by SQL Server 2008 R2 that currently schedules four 6-hour shifts per day. Operational changes now require three 8-hour shifts instead. The change touches two main areas: • Business logic – all routines that build the daily roster, assign staff and calculate shift boundaries work off the 4 × 6 model. • Database structure – several tables store fixed shift identifiers, start / end times, and downstream references that assume four records per day. Because the scheduling and allocation algorithms drive time-sensitive workflows, any adjustment must keep existing calculation accuracy intact. The user interface itself can stay as is; only back-end logic and schema need attention. What I need delivered 1. U...

...off a Windows-only desktop utility and into a fully SQL Server–driven pipeline. All business rules live in clear documentation, every data source has been mapped, and I have a year’s worth of validated invoices to prove the expected outputs. Here is the flow I need implemented: CSV files arrive from carriers, they are ingested into staging tables, T-SQL stored procedures match each line to the appropriate rate-card logic, the correct freight charges are calculated, and the results are surfaced through an API. The API’s main purpose is to let our client application migrate data and trigger the stored-procedure processing as needed. To keep us aligned, these are the concrete deliverables: • Schema for raw, staging, and final tables in SQL Se...

...a dedicated admin dashboard—no code edits or CSV uploads, just real-time forms that write directly to PostgreSQL. Core user-side features come first: powerful product search with layered filters (category, price, trending, etc.), a secure payment gateway integrated end-to-end, and authentic customer reviews with star ratings. Speed and accuracy of those search filters are critical, so efficient SQL queries and smart indexing will be expected. On the back end I want an analytics-style dashboard that lets me watch sales volume and trends at a glance. Charts, tables, and exportable reports should pull directly from live order data. Deliverables • Responsive frontend and PHP business logic tied to a well-structured PostgreSQL schema • Admin module for product &am...

I maintain several large, structured datasets spread across MySQL, PostgreSQL and SQL Server instances. Only portions of the existing schemas are documented, so the very first step will be to inspect each system, reverse-engineer any missing metadata and confirm table relationships. Once the landscape is clear I need all records extracted, cleaned, normalised and deduplicated, then merged into a single, well-organised MongoDB database. Your work should include a carefully planned document model that supports growth, fast look-ups and straightforward analytics. Proper indexing, sharding strategy (where appropriate) and query optimisation are critical because future workloads will be heavy and latency-sensitive. Please deliver: • An optimised MongoDB schema and architectu...
