Enterprise Backend

We build and fix the essential systems your business relies on. We take outdated, expensive setups and turn them into secure and rock-solid applications using modern tech, including Java and Golang.

We provide stability by building systems that handle Petabyte-scale data without slowing down. Using Database Reliability Engineering, we fine-tune PostgreSQL and Redis to keep your operations rock-solid. This focus on performance has allowed us to slash dashboard load times from 30 seconds to under 500ms.

Security and standardization are core to our Zero Data Loss guarantee. We move legacy systems onto standardized, optimized clusters, which have saved clients $500k a year in licensing costs alone. By using advanced tools like StatefulSets and Point-in-Time Recovery, we ensure your data stays safe, organized, and ready to scale.

The Hidden Complexity Behind GitOps’ “Push to Deploy”

Insight

The Hidden Complexity Behind GitOps’ “Push to Deploy”

A GitOps platform that provisioned isolated customer environments straight from Git, and the four problems that surfaced once it was running: dependencies that weren’t ready when resources existed, configuration changes that broke existing tenants, successful deploys that hid broken integrations, and resource limits that blocked work the cluster could handle. The piece documents each fix, the ~110-second provisioning run, and is careful about which numbers are measured observations and which are calculations.

Our Backend Stack

Working with clients across 20+ industries has verified one thing—cookie-cutter approaches do not work when it comes to backend. The backend needs to be tailored for the business and the goal. That is why we do not force one stack on you. We choose the right tool based on performance needs, ecosystem fit, and your team’s expertise.
