  • Building an autonomous Slack agent with OpenCode
    The gateway is the web service that receives requests. I host it on Fly. It accepts Slack events, automation API calls, trigger requests, Composio webhooks, Inngest calls, and runtime calls. - Source: dev.to / 26 days ago
  • It Worked on My Machine (Literally)
    The tunnel was never meant to be permanent (it runs off my laptop, and the URL changes every time it restarts), so the next step was deploying somewhere real. I built the Docker image for Fly.io, set my username, and shipped it. - Source: dev.to / about 1 month ago
  • I Built a Zero-Knowledge Encrypted Habit Tracker with Elixir & Phoenix LiveView
    Three independent encryption layers at rest: client-side E2E, Cloak AES-256-GCM in Postgres, and LUKS disk encryption on Fly.io. - Source: dev.to / 3 months ago
  • One honojs file for entire web scraping API
    I'll also provide github repository in the end, which you can use easily to launch your own scraping APIs on vercel, Cloudflare, netlify or, fly.io or even on a Docker container. - Source: dev.to / 3 months ago
  • Object Storage & CDN Journey
    Tigris (Fly.io) provides globally distributed, S3-compatible storage with low latency, addressing the B2 latency limitations. However, its pricing model includes per-request charges in addition to storage. For an API-heavy workload like a chat system, this would scale poorly, so I decided not to go with it. - Source: dev.to / 3 months ago
