I maintain a live Angular + Dotnet Core application and need someone who can sit with me in Bangalore—preferably on-site, at least for the first few sessions—to quickly enhance the backend. The core goal is to improve an existing system, not start from scratch. Right now the Dotnet Core layer is showing its cracks: data isn’t syncing cleanly between services and several API calls are failing on production, causing intermittent errors in the Angular front-end. I’d like you to dive straight into the repository, isolate the synchronization logic, patch the API communication issues, and leave the codebase cleaner and easier to extend. Key deliverables • Stable, fully functioning Dotnet Core backend with no data synchronization lapses • API endpoints returning expected payloads without timeout or serialization errors • Brief hand-over notes or a pull-request summary so I can follow the changes You should already be comfortable with Visual Studio, Entity Framework Core, SQL Server, Git, and basic Angular debugging so we can trace requests end-to-end while you’re here. If you can drop by our Koramangala office (or any mutually convenient spot) this week, we can kick-off immediately. Let me know your availability and a couple of recent projects where you handled similar Dotnet Core integration fixes, and we’ll take it from there.

With over 13 years' experience as a developer, I am well-versed in the very technologies you have specified for this project, namely Visual Studio, Entity Framework Core, SQL Server, and Git. One of my key strengths as a Freelancer is to create scalable, secure and efficient software. Having worked on various Angular + Dotnet Core projects in my career, I'm no stranger to tackling the kind of backend issues you're currently experiencing. I strongly believe that thorough debugging is key to rapid problem resolution, and my skillset is exceptionally well-suited for this kind of deep technical investigation. Considering the urgency of your situation, I can hop straight into the codebase and systematically debug every layer to find where the synchronization logic is faltering and fix it accordingly. Additionally, I'll patch all API communication issues and guarantee that your Angular frontend no longer experiences intermittent errors. My previous clients would describe me as someone who not only offers technical solutions but also ensures that knowledge transfer always remains a priority. As such, you can expect clear hand-over notes or a pull-request summary from me summarizing the changes that have been made.

I’m a full-stack developer with strong API and backend debugging experience. While my primary stack is MERN, I’m comfortable working across frameworks and have experience quickly understanding existing codebases and resolving production API and data synchronization issues. Since this is an existing live system, I’d prefer to first take a careful look at the repository and current issues before committing to on-site sessions as I am 2hrs+ away from kormangla. Once I’ve gone through the codebase and mapped the backend flow (API layers, data sync logic, and failing endpoints), I’ll be in a much better position to meet in person and discuss fixes or improvements in a structured way. Typically, I can complete an initial deep dive in about 3–4 days, spending roughly 4–5 hours per day reviewing the codebase, tracing the issues, and identifying root causes. During this phase, we can also keep a daily 45min to 1-hour stand-up to align on findings, priorities, and next steps. After this understanding phase, I’ll be able to visit on-site and work more efficiently on targeted fixes and enhancements for your required time. This approach ensures that when we meet, I already have a clear technical understanding of the system and can contribute immediately without wasting on-site time. Happy to start as soon as you can share repository access and a brief overview of the current production issues.

Hello, I can help you stabilize and improve your existing Angular + .NET Core application remotely. I understand this is about fixing and improving what’s already in place, not rebuilding the system. I’m comfortable working with .NET Core, Entity Framework Core, SQL Server, REST APIs, and basic Angular debugging, and I can dive straight into the repository to identify where data synchronization and API communication are breaking down. What I’ll work on Investigate and fix data synchronization issues between backend services. Resolve API failures causing intermittent errors in the Angular front-end (timeouts, serialization, incorrect responses). Verify endpoints return consistent and expected payloads. Clean up affected backend code where necessary to make it easier to maintain. Share clear PR notes or handover documentation explaining what was changed and why. Working approach Remote collaboration via Git, screen sharing, and calls as needed. Focused debugging sessions to trace requests from Angular → API → database. Small, controlled fixes rather than risky large refactors. I’ve worked on live .NET Core systems before where API reliability and data consistency needed attention, and I’m comfortable diagnosing issues directly in production-like environments. I’m available to start remotely and can share my availability and relevant project experience if you’d like to proceed. Best regards, Shahzaib

This project is about stabilizing and enhancing an existing Angular + .NET Core application rather than rebuilding it, and the main risk in live production systems like this is patching surface errors without properly isolating the root cause of API and synchronization failures, so the right approach is to review the current architecture, trace API calls end-to-end, and systematically resolve data sync and serialization issues within the .NET Core layer. I can work directly with you on-site in Bangalore, dive into the repository, debug Entity Framework queries, fix failing API endpoints, address timeout or payload inconsistencies, and leave the backend cleaner, more reliable, and easier to extend, while ensuring smooth integration with the Angular frontend. The focus will be production stability, clean fixes (not temporary workarounds), and clear handover notes summarizing all changes made. I am available to connect in person this week and start immediately. Verma .NET Core & Enterprise Application Specialist

✋ Hi there. I can jump in and fix your .NET Core backend, ensuring data sync works correctly and APIs respond reliably, so your Angular front-end runs smoothly. ✔️ I have solid experience with .NET Core, Entity Framework, SQL Server, and API integration. I previously worked on live applications where I resolved service sync issues, patched failing endpoints, optimized database queries, and cleaned up backend code for easier maintenance. I also handled Git version control and end-to-end request tracing with Angular front-ends. ✔️ For your project, I will review the repository, isolate the data synchronization logic, fix failing API calls, and ensure endpoints return consistent payloads without serialization or timeout errors. I will also refactor and organize the code where needed to make future extensions straightforward. ✔️ I will provide brief hand-over notes or a pull-request summary for your reference, so you can continue development confidently after the on-site session. Let’s chat to confirm timing and your immediate backend priorities. Best regards, Mykhaylo
