Custom Application Support Services
24/7 Incident Response & Monitoring
Your entire application stack is monitored and protected around the clock, with real engineers responding within minutes. We detect issues early, coordinate the response and keep your team updated until everything is back to normal.
Application-Aware Runbooks & System Knowledge
We learn your application inside-out, mapping architectures, dependencies, code paths and failure patterns so support is informed. Every engagement includes a tailored runbook that ensures incidents are handled consistently and with full awareness of how your system really works.
Third-Party & Internal Integration Support
Modern applications rarely run alone, so we support the services your app relies on. Payment gateways, identity providers, ERPs, CRMs, messaging systems, event pipelines, internal or partner APIs. All covered. If it’s part of the customer experience, we help keep it online.
DevOps Support
When your development team signs off, we keep deployments moving and environments stable. We support CI/CD pipelines, manage out-of-hours releases, handle rollbacks, maintain infrastructure-as-code, tune observability and ensure every environment is healthy and ready for the next release cycle.
Performance & Scalability Engineering
We help your application run faster and scale smoothly through performance diagnostics, load testing, caching improvements, API optimisation and modern scaling strategies. Whether you’re preparing for a major release or a seasonal traffic spike, we ensure your app remains responsive and reliable.
Cost Optimisation
Your custom application should be efficient as well as stable. We reduce unnecessary spend by right-sizing resources, eliminating waste, optimising infrastructure and recommending architectural improvements that lower total cost without compromising performance.
Security & Compliance Support
From vulnerability monitoring to identity and access controls, we help keep your application secure and compliant. We support patching, secret rotation, environment hardening and security incident response, all aligned with best practice and relevant industry standards.
Modernisation & Continuous Improvement
As your application evolves, we support the journey. From breaking up a monolith, migrating to containerised or serverless architectures to refactoring for performance or planning a move to a modern cloud platform, we help you improve safely and incrementally, without disrupting your users.

Custom Application Support FAQ
We’ve successfully hosted and supported custom software written in PHP, C# / .NET (Framework & .NET Core), Java, Python and JavaScript / TypeScript on the Node.js runtime.
Why Just After Midnight?
No surface-level support
Custom applications don’t behave like off-the-shelf platforms. You need a partner who genuinely understands your build. Our senior engineers learn your app inside out, code paths, APIs, architecture and all.
Support that fits around your product
We tailor runbooks, workflows and access levels around how your product actually works, so every fix, triage and deployment is done with context.
A team you can actually talk to
No “someone will get back to you soon” or a faceless ticket queue. You get a responsive, named team who knows your application, communicates clearly, and works as an extension of your own product engineering.
Sleep easy
When your internal team logs off, we don’t. Our follow-the-sun engineers keep watch 24/7, handling incidents, deployments, rollbacks and integrations so your team doesn’t get dragged online at 3AM.
