I solve architectural problems in business-critical software systems and AWS environments: when technical debt slows growth down, systems hit their limits under load, or cloud cost gets out of hand. From the analysis through to production.

For CTOs and technical leaders in established companies whose business-critical AWS and backend systems need reliable development or a safe path forward out of what they already run.
Where I come in
Stabilize & scale systems
Modernizing business-critical backends, clearing technical debt and migrating platforms to AWS, without putting live operations at risk.
Optimize your AWS architecture
Three symptoms of the same cause: the bill climbs, a single fault takes the whole application down, and nobody dares to change anything. I work at the places where that gets decided, and I deliver Terraform and code rather than an assessment.
Further specialist areas
A competence and a way of working rather than a third pillar: I build AI and automation in where they genuinely carry a process, with identity, cost, quality and a fallback path settled. It can also be commissioned on its own.

3M+requests per day
Replaced a distributed, manual attribution process with a highly available Go service. Multi-region, under 10ms latency, 3M+ requests per day.
6M+users
A payment API for millions of users that had stopped scaling. Legacy stabilized, new Go microservices built, both systems cleanly integrated.

Legacy code running revenue reporting at nine-figure turnover. Modernized and migrated to AWS in 12 months, without stopping the business.
Cloud & Software Architect
I am Tim Rutte. More than 20 years in software development. Today I build business-critical systems on AWS.
What drives me: systems I touch should end up better than I found them. More stable. More maintainable. More scalable. Not for its own sake, but because bad systems carry a real cost, for teams, for budgets, and for decisions that keep getting postponed.
I work directly, with focus, and with an eye on what pays off. Technically right and commercially sensible are not opposites to me.
Remote, without overhead, since 2003.

Working together
No onboarding weeks, no agency in between. Four steps, and you decide after each one whether there is a next.
You describe the system and the problem. I tell you whether I am the right person, and if I am not, I say so in that same call.
Before anything gets built I look at how the system actually works, not how it is documented. The result is a list: what needs doing, in which order, at what effort.
The first visible benefit arrives early, not at the end. Every step stands on its own and can be reversed, and the running business stays untouched.
The goal is usually that your team can run the system without me, documented and with a rehearsed recovery. If you would rather leave operations with me, that works too.
Client and colleague voices
“When you give Tim a problem, you can be sure that he will identify and fix the real underlying issue instead of wasting time applying patches. Even when that means questioning the current architecture. If you need something complicated (re-)built quickly and profoundly, consider Tim.”
“One of his standout strengths is his approach to legacy systems. Tim can dive into a complex legacy monolith, rapidly analyze the most pressing structural issues, and engineer highly effective solutions in a remarkably short amount of time. He doesn't just patch problems; he architects sustainable fixes that genuinely improve the product.”
“Mr Rutte built a fully custom CRM for us, tailored exactly to our needs. Working together was straightforward. He implemented our requirements perfectly and the system runs absolutely stable.”
“A big thank you to Tim! The AWS migration was a really big chunk for us, but you handled it with complete confidence. Especially with the small issues that came up along the way, you were on it immediately and did not let go until everything ran.”
“Very results-oriented collaboration. Tasks were completed reliably and to a high standard of quality. An unreserved recommendation.”

Frequently asked
With a 30 minute conversation. No pitch, no slides: you describe the system and the problem, I tell you whether I am the right person. If I am not, I say so in that same call.
No, and usually it must not. The modernization and AWS migration of an AdTech platform ran for twelve months while the business kept running, and a 20 year old publishing platform was moved to PHP 8 and Kubernetes without a single day of downtime. Both are in the case studies.
That is the most common case: code with no tests, no documentation and none of the people who wrote it. The first step is then never a rebuild, but understanding what the system actually does today, including the quirks nobody planned.
I build. A recommendation nobody implements has never made a system more stable. If an assessment is all you need, the free Legacy Risk Score is the faster route.
19 questions across four dimensions: release and delivery capability, safeguards and operational stability, knowledge and dependencies, technical debt and platform. The result is a PDF report with your score and recommended actions, prioritized by risk. Free, and about ten minutes to fill in.
A fixed price or billing by time spent, to suit the project and the model you prefer. Clearly bounded work can be scoped beforehand and gets a fixed price. If the work runs longer, or the order of tasks shifts along the way, billing by time spent is usually the more honest model. The analysis packages carry fixed prices, listed on the service pages.
