✅ 𝗖𝗵𝗮𝗹𝗹𝗲𝗻𝗴𝗲 𝗦𝗼𝗹𝘃𝗲𝗱: 𝗥𝗲𝗺𝗶𝗻𝗱𝗲𝗿 𝗘𝗺𝗮𝗶𝗹𝘀 𝘄𝗶𝘁𝗵 𝗛𝗮𝗻𝗴𝗳𝗶𝗿𝗲 𝗶𝗻 𝗠𝘆 𝗝𝗼𝗯 𝗔𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻 𝗧𝗿𝗮𝗰𝗸𝗲𝗿 🧠💼

In my ongoing Job Application Tracker project, I faced a challenge:

👉 I needed to send 𝗿𝗲𝗺𝗶𝗻𝗱𝗲𝗿 𝗲𝗺𝗮𝗶𝗹𝘀 𝘁𝗼 𝗰𝗼𝗺𝗽𝗮𝗻𝗶𝗲𝘀 based on a 𝘂𝘀𝗲𝗿-𝗱𝗲𝗳𝗶𝗻𝗲𝗱 𝗿𝗲𝗺𝗶𝗻𝗱𝗲𝗿 𝗱𝗮𝘁𝗲 while creating or updating a job application.

Here’s how I handled it:

💡 I used 𝗛𝗮𝗻𝗴𝗳𝗶𝗿𝗲, a background job library in .NET, to schedule emails to be sent on the exact reminder date.

🔁 𝗜𝗳 𝘁𝗵𝗲 𝗮𝗽𝗽 𝗮𝗻𝗱 𝗛𝗮𝗻𝗴𝗳𝗶𝗿𝗲 𝗮𝗿𝗲 𝗿𝘂𝗻𝗻𝗶𝗻𝗴, the email is sent exactly at the scheduled time.

⏸️ 𝗜𝗳 𝘁𝗵𝗲 𝗮𝗽𝗽 𝗼𝗿 𝗛𝗮𝗻𝗴𝗳𝗶𝗿𝗲 𝗶𝘀 𝗱𝗼𝘄𝗻, the job stays in a pending state — and 𝗲𝘅𝗲𝗰𝘂𝘁𝗲𝘀 𝗮𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗰𝗮𝗹𝗹𝘆 once both are back up. No jobs are lost. 💪

This helped me:
✔ Keep the app lightweight

✔ Avoid constant polling or manual checks

✔ Learn how Hangfire persists and recovers jobs via database
