Data engineering, learned by doing
Gain real-world data engineering experience
without the real-world risk.
Upsert Labs drops you into hyper-realistic, simulated production environments — messy pipelines, broken data, and real stakes — so you build the instincts that only come from experience.
No setup. No toy datasets. Just the work.
How it works
Enter a simulated environment
Spin up a realistic data stack — warehouses, orchestrators, and pipelines already running, already imperfect.
Solve real problems
Debug failing jobs, model messy data, and ship changes under conditions that mirror an actual production team.
Build proven instincts
Get feedback on your decisions and walk away with experience you can point to, not just a certificate.
Why Upsert Labs
Hyper-realistic environments
Real tools, real scale, real failure modes. The kind of setup you'd meet on your first day at a data team.
Learn by breaking & fixing
Every scenario is built around genuine engineering challenges, not multiple-choice quizzes.
Production-grade tooling
Work with the modern data stack — SQL, orchestration, and pipelines — exactly as you would on the job.
Feedback that matters
Understand not just whether your solution works, but whether it's the one a senior engineer would ship.
