What I build

Integrations, async workflows, and production hygiene—the work behind stable products.

  • //

    Integrations & APIs

    Webhooks, third-party platforms, and auth patterns (including Casdoor) so external systems can talk to yours safely.

  • //

    Async & data

    asyncio workloads, caching, pagination, and solid persistence with PostgreSQL/MySQL—and vector search when the product needs it.

  • //

    Operational quality

    Datadog in production, load testing with Locust, reviews and mentoring—shipping code that teammates can run and extend.
