About Jeferson Oliveira
Staff SRE at Fivetran · ex CTO / Tech Director / Founder
I'm a Staff SRE at Fivetran. Earlier I was Tech Director/CTO at US and European startups, and a founder in LATAM and Ireland. I've been on both sides: shipping as an engineer and founder in fast-moving small companies, and operating at scale as an SRE.
I help founders and small teams from the first cloud account and repo setup through launch and beyond: designing from scratch, standing up CI/CD and environments, and later cutting friction when deploys are slow, outages pile up, cloud bills spike, or everyone says "we need another DevOps person".
I'm comfortable in meetings with engineers, co-founders and investors, to discuss costs, risks, timeline, and what to do next, in plain language.
Software and cloud architecture, VPS/Linux or single-server to major clouds, autoscaling, multi-region networking, CI/CD, and CDN-backed apps, from solo founder to teams with dozens of engineers.
Good topics for a session: CI/CD and how you actually release (GitHub Actions, GitLab, Jenkins, etc.) Cloud setup / cost optimization, AWS/GCP/Azure/Hetzner/D.O., what fits when Production readiness before a launch or fundraise VMs vs Kubernetes: what to use, and when Hiring your first developers or your first platform/DevOps hire Using AI in the engineering workflow: where it helps vs where it's hype Reliability basics: what to measure (SLOs/SLIs) and what to promise customers (SLAs)
These calls are 25–30 minutes of straight talk, not a sales pitch. If you want hands-on help afterward, we can talk separately.
