Sean Floyd

Senior Backend Engineer | Reliable Systems at Scale

9 years of Rails. Now also building production AI systems with Claude Code and MCP. M.Sc. in ML/distributed systems.

At Hivebrite I cut €160k/year in infrastructure costs, took data exports from days to minutes, and halved build times - while the team grew from 9 to 40 engineers. I care about owning systems, not just passing through them.

Grew up across 6 countries (diplomatic family). 4+ years remote across 5 continents, comfortable async.

Actively looking for full-time or contract roles. seanfloyd.dev has the full story.

Proof of Work

claude-rss-news-digest - Daily news digest that runs unattended. RSS feeds, Claude curation via MCP with schema-validated output, HTML email via Resend. Wrote about making it reliable.

Rails Core Contribution - Found a production bottleneck, fixed it upstream. 20x-670x speedup in ActiveSupport.

Jazzify - Volunteer platform for Ottawa Jazz Festival. Built and ran it for 9 years. Production Rails, real users, real ops.

still_active - RubyGem to check if your dependencies are still maintained. Scratched my own itch.

What I Build

  • Platform engineering - Rails, PostgreSQL, Redis, Sidekiq, API architecture (Grape, gRPC, OAuth2), Kubernetes, Terraform
  • Reliability & cost - performance engineering, infrastructure optimization, CI/CD, monitoring (Datadog, OpenTelemetry)
  • Production AI/LLM systems - MCP servers, structured output with schema validation, pipelines that run unattended
