I got my first recommendation on Contra, from Ryan at Haven Lifestyles.
His n8n workflows were taking down the n8n Cloud instance every day. Enterprise plan, and it still fell over after a few hours because too many runs were firing in parallel. Memory limits and workflows too complex. So I refactored the workflows, moved everything to a self-hosted instance, and put monitoring on it with Slack and email alerts.
The daily collapse is gone. Error rate went from up to 12% down to 0.1%, and self-hosting now saves them over $1,500 a month. Thanks Ryan, that was a fun one to dig into.
A lot of companies are looking at automation right now, and n8n is a good place to start. For some clients it also runs AI inside the workflow, handling checks a person used to do by hand on every case.
If you have a process like that eating time in your business, message me.

“Marcel was incredible to work with. Our n8n workflows were continuously crashing the n8n Cloud server. Marcel pinpointed the problems, proposed a solution, and fully implemented it. Tremendous ROI working with Marcel on this.”
24-Hour AI Workflow Blueprint — From Business Problem to Practical AI Plan
I developed a practical workflow-review system designed to help small businesses identify where AI can genuinely save time — and, just as importantly, where human judgement should remain in control.
The process starts with a structured business questionnaire covering repetitive tasks, existing software, time-consuming processes, desired improvements and areas that should not be automated.
That information is then analysed to identify bottlenecks, quick wins and realistic opportunities for AI assistance. The resulting Blueprint provides prioritised recommendations, practical workflows, suggested tools and prompts, implementation steps, and clear human/AI boundaries.
I also built and tested the supporting intake and delivery workflow so the complete review can be produced within 24 hours of receiving the required information.
The objective isn't “AI everywhere”. It's less repetitive work, clearer processes and practical improvements that a business can actually use.
This workflow was developed and internally tested as part of a live 30-day commercial AI experiment. No invented client results or hypothetical savings are presented here.
Rimba is an AI automation platform for Operations, Supply Chain, and Compliance teams in energy and industrials. Built for Oil & Gas, Power & Utilities, Mining & Metal, Supply Chain and Logistics, Chemicals, and Manufacturing.
For this project, I designed the brand and product interface to turn complex, high stakes workflows into something clear and easy to trust. The result is a system that feels as solid and dependable as the industries it serves.
If you are looking for a designer who can bring clarity to complex products, I would love to work together.
