All coordination with foremen currently runs through email, so you must be comfortable driving progress there while bringing structure to the way we capture and store information. Day-to-day you will confirm that the crew snaps all required “before” and “after” photos, chase anything missing, and maintain a live tracker that shows where each site stands. When the work wraps up, you will compile and submit a clean close-out packet that always includes: • Work completion certificates • Full photo documentation (start and finish) If you already have a preferred tracker or software, let me know—our present setu...
I need a lightweight Windows desktop widget that sits neatly on the user’s screen and continuously displays information I’ll supply through a simple data source (local file or web-based API—whichever you find most efficient). The goal is clarity and minimal resource usage: quick launch, low CPU footprint, and a clean UI that matches modern Windows aesthetics. You’re free to choose the framework that best suits rapid, stable development—WPF, WinUI, Electron, or another option you can justify—so long as installation is straightforward for end users. The finished build should include an installer, source code, and brief setup documentation so I can update the displayed data or adjust basic styling without diving deep into the codebase. If you’ve...
I need a repeatable way to trigger Blue Screen of Death events that clearly originate from software-level faults. The goal is purely technical support: I have to reproduce real-world crash scenarios in-house so my help-desk team can practise diagnosis and recovery before we touch customer machines. Here is what I expect: • A small utility, script, or driver that forces a BSOD by invoking the appropriate bug-check routines or other accepted methods. • The crash must be flagged by Windows as a software error, not a hardware failure or driver conflict. • Compatibility with at least one modern Windows build is mandatory; if you can keep the same approach working on 10, 8, or 7 that’s even better. • A concise read-me explaining how to run the trigger, how to ...

I need an experienced hand to turn my paper-based business process into a streamlined digital flow using Microsoft Power Apps and Power Automate. The goal is simple: remove manual data entry, pull information from several sources, and keep everything synced in real time. Here’s what I have in mind • A user-friendly Power App (tablet and web) that captures our operational data and writes it to the right data store—most likely SharePoint lists or a SQL table, but I’m open to your recommendation. • One or more Power Automate flows that collect and integrate that data, move it between systems, and handle any branching logic we need. These flows should run automatically, with clear error handling and logs so we can track issues without digging through the portal...

Summary Senior Software Engineer – Centric PLM Migration (C# / .NET) Duration: 6 months, full-time (~40 hrs/week) Location: Remote Overview: Fabletics is migrating its Product Lifecycle Management system from Centric PLM 7.2 → 8.0. A migration engine already exists in C# (.NET 4.7.2). This role is to take ownership of that codebase, stabilize it, and drive it to production. This is not a greenfield build. You will be working with: - real production data - live APIs with inconsistent behavior - complex dependency ordering across product hierarchies You should be comfortable stepping into an incomplete system and making it reliable. What You’ll Own: Migration Engine (C# / .NET 4.7.2) - Read from Centric 7.2 PostgreSQL HSE tables (ed_style, ...
I’m starting a new C# web project and need someone to spin up a clean, well-structured ASP.NET Core application focused on user authentication. The goal is to have a solid foundation that lets me plug in future features without having to revisit the sign-in logic later. Here’s what I need right now: • A fresh ASP.NET Core solution configured for Web API + Razor (or minimal API if you prefer) • Secure registration, login, logout, and password-reset flows backed by Entity Framework Core • Email confirmation and password recovery endpoints wired to a test SMTP provider (SendGrid sandbox or similar is fine) • Role or claim support so I can gate certain pages behind Admin or Member access later • Well-commented code, clean folder structure, and a ...
I already have a fully packaged code-base for an existing tool and now I need a fresh Windows desktop application that mirrors its user-interface one-for-one. You will receive the current package, screenshots of every screen, and a short walkthrough video; your job is to translate that experience into a modern, maintainable Windows executable. The core logic is in place, so the assignment is almost entirely about recreating the UI: layouts, navigation flow, dialogs, and visual behaviour. Feel free to propose WinForms, WPF, Electron, or any other Windows-friendly framework you are comfortable with as long as the final result installs easily and runs smoothly on Windows 10 and 11. Good naming conventions, clear project structure, and concise in-line comments are essential because this cod...
I’m expanding an e-commerce platform built in ASP.NET and need a developer who can stay with the project long term. The core work revolves around three pillars: solid user authentication, seamless payment integration, and reliable product catalog management. Where you’ll really make a difference is in automated document printing. Every order should trigger receipt, invoice, and shipping-label output without manual clicks, working smoothly across common browsers and printers. If you’ve already tackled auto-printing in web apps—handling silent printing, printer selection, and layout fine-tuning—you’ll feel right at home here. We iterate quickly, so clean, well-commented C#/ASP.NET code, Git familiarity, and clear communication are essential. Let me k...
I have a desktop application that was originally compiled in C#. Its only task that now needs attention is the SMS routine. At the moment the program calls a small, home-grown web service; I can share full documentation for that existing endpoint so you will immediately see the parameters and payload it expects. Here is the new goal: whenever the application sends a message it must instead post to Africastalking’s bulk messaging REST endpoint ( ). All other behaviour in the app should remain untouched. I already own commercial decompilation tools and can provide you with a clean project skeleton produced from the executable, so you can focus purely on refactoring the SendSms() logic, wiring in the required headers, URL parameters, JSON body and authentication for Africastalking. ...
We need an experienced SharePoint expert to build an advanced, reusable set of rules that can streamline how our team collects, classifies, and preserves legal evidence. The goal is to ensure that all records received in any form—such as uploaded files, emails, and scanned court documents—are automatically moved to the correct library, receive appropriate metadata, and have the correct permissions and retention settings applied, all without manual intervention. The key points I am already aware of are as follows: • Rule-based routing that operates based on metadata or content types • Automatic versioning and locking of evidence to prevent accidental overwriting or deletion • Searchable, tamper-proof audit logs What we will provide is: • SharePoint tena...
Build a business automation system (ERP) with desktop application, mobile app, workflow, contracts management, and OTP authentication using .NET and Flutter
At Cannitix Solutions Pvt Ltd I am expanding a distributed product team and need a full-time developer who is equally comfortable crafting API-driven back-ends and polished user experiences. Your day-to-day work will revolve around building and extending scalable web applications in .NET Core, persisting data through Entity Framework, and delivering dynamic front-end interfaces with Angular.

Clean code, readable tests, and maintainable architecture matter to us as much as shipping on schedule. Key areas you will own: • Designing and implementing RESTful services, business logic, and data layers in .NET Core + Entity Framework ...

I’m dealing with a software bug on a Windows machine that’s blocking normal usage, and I need a fresh set of expert eyes to get it resolved quickly. This is strictly a technical issue: no design or content work is involved—just good old-fashioned debugging. Here’s what I need from you: • Reproduce the bug reliably on Windows 10/11 (I’ll supply version details, logs, and a video). • Trace the root cause—whether it sits in the codebase, an external library, or a mis-configured dependency. • Deliver a clean, well-commented fix or a detailed set of steps I can follow to apply the patch myself. • Verify the solution with me over a quick screenshare before we call it done. The code is in Git, built with Visual Studio and .NET, so ...
I’m currently looking to build a long-term collaboration with a skilled developer for upcoming and ongoing projects. I’m particularly interested in working with someone who has strong expertise in technologies such as .NET, C#, React, and Node.js, along with excellent English communication skills, as these are essential for effective collaboration and client-facing work.

Need an experienced VSTO developer for dedicated projects
Both of my access-control platforms—System A (Suprema's Biostar X) and System B (dormakaba's Matrix Professional)—sit on the same Windows server and share a local MS SQL instance. Each exposes a REST API, yet today they operate in silos. I need a seamless, bi-directional integration so that any change to a person or employee record in one system is reflected in the other almost instantly. Scope of the sync • Core identity fields: name and unique ID • Credential data: RFID card number and state • Biometric assets: fingerprint templates • Media: profile picture • Security attributes: access-level permissions Key requirements 1. Real-time operation (sub-second latency acceptable). 2. Conflict-resolution logic—latest change...
