Before we got here,
here's what wasn't working.
n8n implementation projects for clients who need powerful workflow automation without sending data to third-party cloud services. Self-hosted on AWS or on-premises, these workflows handle everything from data pipelines to AI-powered enrichment chains.
We confirmed every challenge with the team before writing a line of production code. The right column lists the pain points we tackled head-on and how we approached each one.
What wasn't working
BEFOREn8n memory spikes on large-payload workflows
Refactored large workflows to use streaming and chunked processing, keeping memory usage flat.
Don't over-engineer.
Solve what matters, ship fast.
The instinct on complex projects is to rebuild everything from scratch. We pushed back. A full rewrite often means months of regressions while engineering rebuilds features that were already working.
We mapped the existing workflow against actual usage. The result was clear: a small set of features accounted for the majority of user time. We rebuilt the core, shipped fast, and extended outward.
On the technical side, we made clear decisions early and held them. The right column shows what we chose, and why.
4 decisions we made early
CHOSEN / REJECTEDSelf-hosted Deployment — how we built it

4 features that
define the product experience.
Every feature was scoped and shipped with the same priorities: speed, reliability, and staying out of the user's way.
Self-hosted Deployment
Dockerised n8n deployed on AWS EC2 or on-premises with automated backups and monitoring.
AI Enrichment Workflows
n8n workflows that pull data, enrich via OpenAI, and push to downstream systems.
Error Alerting & Retry Logic
Built-in retry mechanisms and Slack/email alerts for failed workflow executions.
Custom HTTP Nodes
Custom n8n HTTP nodes for internal APIs that lack native n8n integrations.
What changed,
measured against the day-one baseline.
We benchmark before we touch anything, logging every metric below against its state before we wrote a line of production code.
