Supporting your custom application

Just After Midnight provides tech-enabled, 24/7 support for custom applications across SaaS, fintech, health, logistics, legal tech and more. We monitor your full stack, respond to incidents within minutes and work seamlessly alongside your development team to keep your platform running around the clock.

When your business runs on a custom-built application, uptime isn’t optional. You need a partner who understands your code, your architecture and your users. A partner who can keep everything stable, fast and online while your team focuses on shipping new features.

That’s where we come in.

  • List Item Icon Built for the systems that don’t fit a template
  • List Item Icon 24/7 support without the “phone by the bed” model
  • List Item Icon Deep understanding, not superficial triage
  • List Item Icon Support for every component in the chain
  • List Item Icon DevOps and cloud operations baked in
  • List Item Icon Reliability, performance and cost continuously improved

What we support

From fintech to legal tech, enterprise to scaleups, we support modern and legacy application architectures across cloud-native, on-prem-to-cloud and hybrid environments:

  • .NET / .NET Core
  • Node.js, Python, Java
  • PHP / Laravel
  • JAMstack & headless architectures
  • Microservices, serverless and event-driven systems
  • Bespoke enterprise software built in-house or by external agencies

If your application is custom, distributed or business-critical, it’s exactly the kind of thing we support 24/7. Our expert engineers have years of experience working with a range of custom applications in the not-for-profit, private, medical sectors, and many more.

So whatever your business, we’re ready to function like a member of your team from the word go, creating a detailed runbook of tasks and solutions based on your own, fulfilling technical users’ requests and managing and solving incidents quickly. 

Why we’re different

We were built for the always-on world. When you rely on a custom application, “9–5 support” or phone-by-the-bed just isn’t good enough. Our follow-the-sun model means every incident is handled by an alert, senior engineer working in their normal day. Not someone dragged out of bed at 3am.

We learn your system properly: the architecture, the workflows, the failure paths, the quirks. That means no generic L1 triage and no hand-offs that slow everything down.

Whether you need deep, hands-on support with full access or a tightly scoped operational layer over your existing team, we fit around your stack and your way of working.

At the heart of it all: we’re here to protect your revenue and reputation, 24/7, 365.

Why teams choose Just After Midnight:

  • Born in the cloud-native, always-on era
  • Senior cloud, DevOps and application engineers
  • True follow-the-sun coverage across global time zones
  • Full-stack support with tight SLAs

What are the impacts of incidents on teams and revenue?

According to industry sources, downtime costs businesses between $540,000 (Splunk, The Hidden Costs of Downtime) and $2 million (New Relic, Observability Forecast 2025) per hour for many high-impact outages. Incidents also consume significant engineering capacity: the median engineering team spends 30% of its time addressing disruptions (New Relic, Observability Forecast 2024).

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.
