Application Management

For complex, interconnected systems stuck in firefighting mode. We take them over with senior engineers, stabilize support, and get them evolving again. No documentation? Not a problem — we read code and map what your application actually does.

Fact: our clients include companies with €1bln annual turnover, and 74% of them come by referral.

We Know Your Pain

  • Bugs sit in the backlog for weeks — nobody dares to touch the code
  • Customers wait days for answers, then leave without a word
  • Every ticket is “priority #1”, so the team only firefights
  • The people who built the system are gone, and the documentation ends two years ago
  • Every new feature breaks two old ones

Sound familiar? We’ve walked into this exact situation dozens of times. We know where it hurts, we know why it happens, and we know how to fix it — we’ve done it for companies with up to €1bln in turnover.

Takeover & Audit

No documentation? Not a problem. We read code. Our engineers, backed by AI-assisted code analysis, map what your application actually does — not what the outdated docs claim. In weeks you get certainty about what you own:

  • Codebase analysis and dependency mapping
  • Architecture and integration audit
  • Recovered, up-to-date documentation
  • Risk assessment and takeover plan

Support That Answers

Your users get responses, not ticket numbers. Senior engineers stabilize support first, then turn the firefighting backlog into a roadmap. We commit to SLAs and report on them:

  • SLA-backed incident response
  • Bug fixing with root-cause analysis, not patches
  • Communication in your time zone, in plain English
  • Transparent monthly reporting

Refactoring & Modernization

Complex systems degrade unless someone owns their health. We refactor continuously, in small safe steps — while the application keeps running. Our focus:

  • Incremental refactoring without downtime
  • Legacy code and framework upgrades
  • Performance optimization
  • Security hardening and compliance

Evolution, Not Maintenance

Keeping the lights on is the baseline. Your market changes, and your application has to follow. The same team that supports your system builds what’s next:

  • New features without a handover between support and development
  • Integrations with the tools your business adopts
  • Scalability work ahead of growth, not after the outage

The 24*7 Model

During the day, our engineers work with you: decisions, features, demos. At night and on weekends, autonomous AI workflows keep working on your system. You pay for 8*5 hours. You get 24*7 development.

  • Code review at scale
  • Automated test runs and fixes
  • Security and compliance checks
  • Refactoring that needs no client input

Start Small, Scale on Trust

We enter with 2–3 senior engineers, not a crowd. Once the system is stable and the results are visible, the team grows exactly as fast as your needs do. Why companies trust us:

  • Customers with €1bln annual turnover trust us with their core systems
  • 68 clients, 154 projects, 22 countries
  • 74% of clients come by referral
  • ISO 9001 and ISO 27001 certified (TÜV Austria)

Frequently asked questions

Can you take over a system that has no documentation?

Yes. Engineers backed by AI-assisted code analysis read the codebase and map what the application actually does, rather than what outdated docs claim. You get recovered documentation, a dependency and integration map, a risk assessment and a takeover plan.

How long does a takeover take?

Two to three weeks to audit the system and recover its documentation. At the end you have certainty about what you own — codebase and dependency analysis, an architecture and integration audit, a risk assessment and a takeover plan — before anyone changes a line of code.

How many engineers do you start with?

Two to three senior engineers, not a crowd. The team grows once the system is stable and the results are visible.

Do you commit to SLAs?

Yes. Incident response runs against agreed SLAs, with monthly reporting on how they were met, root-cause analysis instead of patches, and communication in your time zone in plain English.

Can you take over a system built by another vendor?

Yes — that is the normal starting point. Bugs sitting untouched in the backlog, the original authors gone, documentation two years stale, every new feature breaking two old ones. FusionWorks has walked into that situation dozens of times, including at companies with €1bln turnover.

Do you only keep the system running, or also build new features?

Both, with the same team. Keeping the lights on is the baseline; the engineers who support the system also build new features, integrations and scalability work — no handover between a support team and a development team.

What happens to the code and documentation if we end the engagement?

You own the code and all recovered documentation throughout — full IP, transferred on payment. On exit there is a structured handover of two to three weeks: knowledge transfer sessions, access transfer and a written summary of the system’s current state.
