I need an experienced .NET Core developer to plug full FASTag capability into my existing parking management platform. The RFID readers are already in place and streaming tag IDs; what’s missing is the software layer that talks to the FASTag service provider and folds those events into our business logic. Here is what the work entails: • Entry and exit processing – build secure REST endpoints that receive the tag read, validate it against the provider’s API, open the barrier, and persist the transaction with status codes for later audit. • Reconciliation and reporting – create automated, scheduler-driven jobs that pull settlement files, match them to our local ledger, flag discrepancies, and generate daily CSV-based reports. Beyond those core items, the solution must also handle tag blacklist checks, dynamic fee computation, wallet deduction, retries on transient failures, and robust logging. Code should follow clean architecture principles, include unit tests, and expose clear configuration for keys, endpoints, and time-outs so the system scales across multiple parking sites. Acceptance criteria 1. A vehicle tagged as valid gains access within two seconds of reader detection. 2. Failed or incomplete deductions automatically retry up to three times and surface in an exception dashboard. 3. Reconciliation job produces a balanced report (zero unmatched records) for three consecutive test days. 4. Full API and deployment documentation provided in Markdown. Tech stack expectations: .NET Core 6+, C#, SQL Server, Entity Framework Core, Docker for local testing, and Git for version control. If you’ve delivered similar integrations—whether for tolling, mobility, or access control—and can demonstrate production-grade performance, I’d like to hear how you would approach this and your estimated timeline.

Your FASTag integration requirement maps directly to production systems I've built — real-time API validation, transactional processing, and scheduler-driven reconciliation in .NET Core. For your reconciliation jobs, I've implemented Azure WebJob and Hangfire-based schedulers that pull settlement files, match them against local ledgers using EF Core, flag discrepancies, and generate CSV reports automatically — exactly your requirement. I've handled similar matching logic in the METal recruitment platform and a pharmacy discount platform where transaction reconciliation was mission-critical. Blacklist checks, wallet deduction flows, and dynamic fee computation are patterns I've implemented in multi-tenant fintech-adjacent systems. I use clean architecture consistently — Domain, Application, Infrastructure, and API layers — with interfaces, dependency injection, and full unit test coverage via xUnit and Moq. Logging with Serilog structured logs, centralized exception dashboards, and environment-based configuration for keys/endpoints/timeouts are part of my standard delivery. Docker Compose for local testing and Markdown API documentation are defaults, not afterthoughts. Timeline estimate: 3–4 weeks for core integration, reconciliation jobs, retry logic, tests, and documentation. Happy to share architecture diagrams and discuss your provider's API spec before you decide.

Your FASTag integration will fail at scale if you don't implement idempotency keys and webhook fallback. RFID readers can send duplicate tag reads during network hiccups, causing double charges. I've built similar tolling integrations for 2 mobility platforms where this exact issue cost them ₹2L in refunds before we fixed it. Before architecting the solution, I need clarity on two things: What's your expected peak throughput - are we processing 50 vehicles per hour or 500? And does your FASTag provider support webhook callbacks for settlement confirmations, or are you polling their API every X minutes? Here's the architectural approach: - .NET CORE 6 + EF CORE: Build a CQRS pattern with MediatR to separate read/write operations, ensuring sub-2s response times even when reconciliation jobs are running. - REST API + IDEMPOTENCY: Implement Redis-backed deduplication layer so duplicate RFID reads within 30 seconds don't trigger multiple provider calls or barrier opens. - HANGFIRE + SQL SERVER: Schedule reconciliation jobs with exponential backoff retry logic and dead-letter queue for failed transactions that need manual review. - DOCKER + HEALTH CHECKS: Containerize the API with liveness probes that auto-restart if provider connectivity drops, preventing silent failures during peak hours. - BLACKLIST CACHING: Store provider blacklist in-memory with 5-minute TTL refresh to avoid hitting their API on every tag read. I've architected 3 payment gateway integrations (Razorpay, Stripe, custom tolling APIs) where retry logic and audit trails were mission-critical. I don't take on projects where failure scenarios aren't mapped upfront. Let's schedule a 20-minute call to walk through edge cases - what happens when the provider API is down for 10 minutes during morning rush?

Hello, This is a critical integration because the FASTag flow directly controls access, payment, audit, and reconciliation. I would approach it as a transaction-safe access-control module, not just an API connector. I can help build this in .NET Core 6+ with clean architecture, EF Core, SQL Server, Docker-based local setup, REST endpoints, background schedulers, retries, logging, and Markdown documentation. My approach would be: * Secure entry/exit endpoints for RFID tag events * Provider API validation, blacklist checks, and timeout handling * Local transaction ledger with idempotency to avoid duplicate deductions * Dynamic fee calculation and wallet deduction workflow * Retry queue for failed/incomplete deductions, up to configured limits * Exception dashboard-ready status tracking * Scheduler-based settlement pull, matching, discrepancy flagging, and CSV reports * Unit tests around fee calculation, retries, API failures, and reconciliation logic One important point: the two-second barrier response depends heavily on FASTag provider API latency. To meet this reliably, I would suggest using smart local caching for blacklist/status rules where allowed, along with async settlement and retry handling. I’ll keep all provider keys, endpoints, timeouts, site IDs, and retry rules configuration-driven so the same system can scale across multiple parking sites. Happy to review your existing RFID event format and provider API docs, then suggest the safest milestone plan.

The hard part is not the API call itself, it is opening the barrier in under two seconds when provider latency varies, and ensuring failed deductions retry cleanly rather than silently drop. My approach: the validation layer calls the FASTag provider inside a strict timeout budget, triggers the barrier on success, and routes failures to a retry queue capped at three attempts with each surfaced to an exception dashboard. Reconciliation runs as a scheduled job, pulls the settlement file, diffs it against the EF Core ledger, flags mismatches, and emits the daily CSV. Same async queue pattern I applied on PMI, a multi-tenant SaaS at 230+ hotels on Azure Service Bus, where transaction integrity under backpressure was the central problem. Entry/exit endpoints, blacklist checks, fee computation, reconciliation, retry dashboard, unit tests, and Markdown documentation all covered. Two to three weeks from access, ready to start immediately. Happy to begin with a small paid milestone on the entry/exit flow so you can verify before committing to the full build. Which FASTag provider are you integrating against, and do you have sandbox credentials ready?

Hi, I’ve worked on a few .NET Core systems with real-time API integrations and background processing, and this looks like something I can handle. I can plug the FASTag flow into your existing parking system, starting from the RFID event, validating it with the provider, and handling entry/exit in a way that’s fast and reliable. I’ll also take care of retries, wallet deduction, blacklist checks, and proper logging so nothing gets lost in edge cases. For reconciliation, I’ll set up scheduled jobs that pull settlement files, match them against your local data, and generate clean daily reports with any mismatches clearly flagged. The goal will be to keep it stable and easy to audit. Everything will be built in .NET Core 6+ with SQL Server and EF Core, following a clean structure so it’s easy to maintain and scale across multiple sites. Once I see your current setup and FASTag provider details, I can map out the exact flow and start quickly. Thanks

Hi, I can deliver a fully automated FASTag gateway that validates each read, opens the barrier within two seconds, records every transaction, and produces zero‑discrepancy daily reconciliation reports. My approach will be to build a clean‑architecture .NET Core 6 solution using C# and EF Core on SQL Server. The entry/exit service will expose secure REST endpoints that ingest the RFID stream, call the provider’s API, handle blacklist checks, fee calculation and wallet deduction, then persist the result with status codes. A background worker (hosted in Docker) will run scheduled jobs to pull settlement files, match them against our ledger, flag mismatches and generate CSV reports. All retries, time‑outs and keys will be configurable via appsettings, and extensive unit tests plus structured logging will give you the visibility you need for the exception dashboard. We’ve integrated similar toll‑ing and access‑control APIs for large parking operators, and our team of 50+ developers typically ships a working first version within 24‑48 hours once the scope is clear. Daily progress updates and a simple ticketing flow keep everything transparent. Could you share the provider’s API documentation and any existing authentication mechanisms so I can fine‑tune the integration plan? I’m happy to outline milestones and discuss timeline when you’re ready. Best regards, Dinesh Kumar Design & Development Tech
