I’m building a web-based health-tech platform and need an experienced .NET developer (around two years of hands-on work) to take ownership of the appointment-scheduling feature. The core of the project is an ASP.NET web application; everything else—design language, database schema, deployment—revolves around that stack. You’ll be enhancing a green-field codebase, so clean architecture and clear naming conventions matter to me. The main goal for this phase is to let patients browse available time slots, book, reschedule, or cancel appointments, while giving practitioners an intuitive dashboard to manage their calendars. Think responsive pages, reliable time-zone handling, and automatic email confirmations. Tech at a glance: ASP.NET (Core or Framework), C#, Entity Framework (or Dapper if you prefer), SQL Server, a bit of JavaScript for interactive UI elements, and Git for version control. If you have experience wiring up calendar APIs or sending transactional email through services like SendGrid, even better. Deliverables for this milestone: • A runnable .NET web solution that compiles error-free • Database scripts or migrations for the scheduling tables • A minimal but functional front-end flow for booking and managing appointments • Setup notes so I can reproduce the environment locally (connection strings, seed data, etc.) Acceptance criteria will be straightforward: the app builds from a fresh clone, appointment data persists to SQL, and basic edge cases—double booking, conflicting time slots—are gracefully handled. If this sounds like a good fit, let’s discuss timelines and get started.

Hello, I’d be a great fit for this project. I’m an IIT graduate with 21+ years of software engineering experience and currently a Principal Software Engineer at a major tech company, where I build scalable enterprise applications and backend platforms. I have strong hands-on experience with ASP.NET Core, C#, Entity Framework, SQL Server, REST APIs, and appointment/scheduling workflows. I can help design and implement a clean, maintainable scheduling module that supports booking, rescheduling, cancellations, practitioner calendar management, timezone-aware scheduling, email notifications, and robust conflict prevention. I place a strong emphasis on clean architecture, clear naming conventions, database design, and production-quality code. The solution will include migrations/scripts, setup documentation, and proper handling of edge cases such as double booking and concurrent slot reservations. I’m comfortable working in green-field environments and can deliver a solution that is easy to maintain and extend as your health-tech platform grows. Happy to discuss timelines, architecture, and the current state of the codebase.

Appointment scheduling lives or dies on the two things your post already flags: reliable time-zone handling and clean double-booking prevention. Those are exactly where a cheap build leaks bugs, so I'd enforce slot conflicts at the database level with real constraints, not just UI checks, and store everything in UTC with display-time conversion. Stack as you described: ASP.NET Core, C#, EF Core migrations, SQL Server, SendGrid for transactional confirmations, light JavaScript for the calendar interactions. Greenfield, so clean architecture and naming from the first commit. A note on price: I've bid above the listed range on purpose. Getting timezone correctness, conflict integrity, and reliable email right the first time costs more than a placeholder budget, but it saves you the rework cycle that usually follows the cheapest bid. I'd rather quote the real number. M1 solution scaffold + EF schema/migrations M2 patient booking + timezone handling M3 reschedule/cancel + conflict guards M4 practitioner dashboard + email + setup notes Core or Framework, do you have a preference?

Hi, we can take ownership of the appointment scheduling module in your ASP.NET health-tech platform. Felixphase Technologies works with ASP.NET Core, C#, Entity Framework, SQL Server, JavaScript, Git, APIs, and email integrations. For this milestone, we’ll keep the architecture clean, readable, and easy to extend. We can deliver: * Patient slot browsing, booking, rescheduling, and cancellation * Practitioner calendar/dashboard * SQL tables with EF migrations or scripts * Conflict handling for double bookings and overlapping slots * Time-zone-aware scheduling * Email confirmations via SMTP/SendGrid * Local setup notes with seed data and connection settings Estimated timeline: 2–3 weeks for a stable milestone, depending on current codebase structure and UI expectations. A few questions: 1. Is the project ASP.NET Core MVC, Razor Pages, Blazor, or Web API + frontend? 2. Do practitioners define availability manually or through recurring schedules? 3. Should email confirmations include calendar invites? Happy to review the codebase and start with the booking flow.
