SuperStack is a small senior team partnering with companies on DevOps and full-stack engineering. Most of what we build and support lives inside private client infrastructure, so public write-ups go up only with sign-off. Below is a sample of the kind of problems we're a good fit for.

Fintech Automation Platform
Migrated stateful browser automation workloads from StatefulSets to Deployments, wired KEDA event-driven auto-scaling to queue depth, and fixed a CI pipeline tagging bug that was silently shipping stale images to production.
Employee Wellness SaaS
Ongoing backend engineering support for a production Django/DRF SaaS platform — fixing role-scoping bugs in the critical incident response module, hardening queryset access control, and adding a parameterised test suite for multi-role edge cases.
Tier-1 Banking Group
Embedded engineering for a tier-1 financial institution — React web, React Native mobile and a Django backend on AWS, with pipeline governance, cost optimisation and release discipline inside a regulated environment.
UK Creative Studio
A Next.js application combining AI-assisted design generation, a zoomable canvas interface, role-based dashboards for studios, artists and clients, and secure asset storage on AWS S3.
National Retail Group
Modernised the Cordova build toolchain of a business-critical hybrid mobile point-of-sale app — unblocking Android platform requirements without a rewrite, verified end-to-end and shipped through Azure DevOps release trains.
Real-Estate SaaS Studio
Built a real-estate asset management web app with end-to-end type safety — React, tRPC and Prisma — backed by Jest/RTL tests, Storybook, SonarQube quality gates and a GitHub-to-AWS deployment pipeline.
Most of what we build lives inside private client infrastructure. These write-ups are published with client sign-off and anonymised where requested. Talk to us about your specific problem.
