  1. Kurslog team
    ยท Working at Kurslog ยท

    When our backend team needs to build services for data parsing, aggregators, or high-load APIs, FastAPI is our absolute go-to choice. It completely lives up to its name-development speed is outstanding.

    The combination of Pydantic for data validation and built-in async support keeps our shared codebase clean, strictly typed, and reliable. But the biggest highlight for our cross-functional team is the automatic generation of interactive OpenAPI (Swagger) documentation. Our frontend and mobile developers no longer have to wait for backend engineers to manually update API docs; everything stays perfectly in sync automatically. It has drastically improved our team's communication and delivery speed.

  • Anyone else getting bombarded with invoice spam emails? Iโ€™m using a custom domain. These have been relentless for months.
    Sure. I have an account with mailgun, though I have heard good things about sendgrid as well. It costs me $35/mo, but I use the account as part of the management of a phpbb forum I host, but I have a patreon for that that covers the expenses. If I didn't have that patreon, I would have to think pretty hard about how to proceed. Source: about 4 years ago
