Hi, I'm Lucas (Luk)

Currently at Thoughtworks (Chicago, remote from GMT-3) · 4+ years shipping cloud-native systems for platforms serving 100k+ monthly users.

What I do

I build secure, scalable cloud-native backends and the full-stack interfaces that sit on top of them. Day job is senior consulting work at Thoughtworks — two years of it also at CI&T before that, so I'm comfortable in international cross-functional teams with tight review cultures. Off-hours I run a homelab, ship Discord bots with real users, and write AI-developer tooling.

Impact highlights:

  • 100k+ monthly users supported on backend infra I built/maintained (Node.js + AWS Lambda)
  • Deployment time 6h → 2h (−30%) by moving to serverless + tuning CI/CD
  • Incident response +40% faster via Splunk/CloudWatch observability
  • Production errors −25% through Mocha/Jest unit + integration coverage
  • Internal workflow efficiency +40% via automations and tool-building
