I already have a working C# WinForms LaTeX editor, but it still feels rough around the edges. The highest-priority fixes sit in the keyboard and mouse event handling inside the main text-editing surface: shortcuts intermittently fail, click-to-focus can be sluggish, and certain selection operations break when LaTeX commands are present. Beyond stabilising those events, I want the editor to behave as a true LaTeX WYSIWYG environment. That means: • Real-time preview that updates instantly as I type. • A reliable equation editor pop-up for inline and display math. • Drag-and-drop capability so users can move sections, figures, and tables around the document fluidly. If you refactor parts of the editor for better structure or inject a dedicated syntax-highlighting compo...

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.

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...

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 full-stack, self-hosted .NET solution that runs a 2 × 2 matrix MLM system. The site must let new members register under a sponsor, automatically position them in the chain, and reflect spill-over earnings in real time. Core roles are Standard user, Sponsor and Admin. A registered user should see a clean dashboard that shows an earnings overview, live balance details and a searchable transaction history. From that same panel they must be able to deposit, withdraw or transfer BEP20-based USDT, with each on-chain action recorded to the ledger and mirrored instantly in the database. The admin control panel must allow me to browse every account, approve or reject any pending deposit/withdraw request, modify wallet addresses if needed, and trigger manual payouts. Every sensitive...

I’m building a new travel portal that should feel and flow almost exactly like Onetravel (about 90% of its current UX), but written end-to-end in .NET with Bootstrap so the layout stays fully responsive on every page. Core flow From Search → Listing → Detail → Add-On → Contact → Payment → Confirmation each module has to work seamlessly. For demo I need the Flight booking piece up and running before we expand to Hotel, Car, Bus and Holiday packages+ an Android app for the same Flight module must include • Search flights • Flight details page • Add-on services (bags, seats, meals, etc.) • Contact • Payment • Confimation page with Email to user • Data Saved on Google Sheets as Tables Under the hood • Mo...

I’m building a green-field product that needs a solid foundation across web, mobile and cloud. The server side will run on .NET (Core/Framework) and expose RESTful endpoints organised as micro-services. For the browser I’m happy with either Angular or React—pick whichever you are fastest with—and the companion mobile app will be written in React Native so we can share as much logic and styling as possible. The data layer can land on SQL Server, a NoSQL store or a mix of both; I’m open to your recommendation as long as the choice is justified and future-proof. Everything will be hosted on AWS or Azure, wired into a CI/CD pipeline (GitHub Actions or Azure DevOps are fine) so every commit ships automatically through test, staging and production. Clean code, SOLI...

Our live platform, built on .NET Core (MVC, C#), needs an experienced bilingual Arabic/English developer to step in on a part-time basis and keep everything running smoothly while we roll out new capabilities. The work is time-sensitive—ideally code starts moving this week—so I need someone who can plug in and contribute immediately. Scope of work The current solution spans several modules that exchange data with internal and third-party services. Typical tasks include tracing and resolving production issues, refactoring brittle sections for performance, tightening security around existing endpoints, and adding small to medium features as specifications come through. You will work against an Azure DevOps repository, create pull requests with meaningful commit messages, and d...

I’m hiring a seasoned .NET + Angular engineer who can act as a personal mentor for a friend of mine in Udaipur. She has three years of support experience in infosys and has just moved into an SDE role in different company, so she needs guided, practical coaching rather than generic tutorials. The focus is pure mentorship and guidance delivered through one-on-one video calls. During these sessions you will walk her through the tickets already assigned to her, explain the underlying concepts, review her code, and show her how to debug, refactor, write tests, and follow best practices that align with real-world enterprise workflows. Early in the engagement I’ll also need a brief, well-vetted shortlist of a few additional .NET/Angular tutors (with phone numbers) so we have backup...

I need a Windows-based typing application, built to mirror the exact pattern used in Indian government recruitment exams. The program must run smoothly in both online and offline mode so that a candidate can practise anywhere and then sit a timed test even if the internet drops. Core functionality • Practice mode stocked with graded typing exercises. • Full-length mock tests that reproduce the official exam interface, timer and font rendering. • A performance dashboard that tracks speed, accuracy and trend lines over time. Language support All content, UI prompts and result reports should work in English and Hindi from day one. If you architect the system cleanly I can add further regional languages later, so keep strings externalised. Benchmarks Speed and accur...

I need a custom Windows-compatible control panel that can automatically handle Zynga Poker chips from end to end. The core of the project is threefold: • Chip generation – the panel must reliably create chip quantities I can define on demand. • Transfer management – once generated, the chips should move between accounts smoothly, with options to schedule or batch transfers. • User account control – I have to be able to add, edit, suspend, or delete game accounts directly inside the panel. Code quality and stability matter more to me than flashy graphics, so feel free to use a lean UI framework that keeps things fast and uncomplicated. A clear dashboard, real-time status indicators, and basic logging/export will cover my day-to-day needs. You are fre...

I’ve already built a working medical prototype inside Google AI Studio and now I need it packaged as a true standalone Windows desktop application. The main responsibilities will be: • Re-architecting the current Google AI Studio build so it installs and runs natively on Windows without any command-line dependencies. • Designing a data layer that lets each clinic choose either a local, offline database or a secure cloud-hosted option, with an easy switch between the two. • Implementing strong security around patient records and treatment plans: encryption in transit and at rest, role-based access, and a well-structured authentication flow. • Guiding me through code signing, installer creation, and any compliance considerations typical for medical software. ...
