I write about the things I ship in production. Recent posts on tufail.dev/blog:
- Why we replaced LangChain with the raw Anthropic SDK in production — 33% lower p95 latency, 77% less code
- Building MCP Servers in Python: a production primer for 2026 — FastMCP, Streamable HTTP, OAuth 2.1, AWS deployment
- FastAPI at 1M+ users: the patterns that actually matter — lessons from running Savyour at scale
- Cutting our Claude API bill by 78% with prompt caching — $4,200/mo → $920/mo, real numbers
- Spec-driven development with Claude Code — the workflow that doubled my output
