About this gig

Most n8n workflows on Fiverr work in the demo and break in production. Mine don't.


I build n8n automations that handle real traffic proper retry logic, idempotency, race condition handling, and error paths that mean your workflow keeps running when an upstream API hiccups instead of silently dropping data.


WHAT YOU GET

- A workflow built the way a senior engineer would build it, not a no-code tutorial

- Documentation explaining every non-obvious choice

- Source JSON you can import to your own n8n instance

- Reasonable revision turnaround (I check messages morning and evening MYT)


WHAT I WORK WITH

n8n (cloud or self-hosted), Supabase, Postgres, REST APIs, webhooks, Cal.com, WhatsApp Business API, OpenAI / Claude APIs, Google APIs.


WHAT I DON'T DO

- WordPress automation

- Pure Zapier work

- "Make my chatbot smart" without a defined scope

- 24/7 support contracts


PORTFOLIO

GitHub case studies in profile: message debouncer with queue + optimistic lock, multi-tenant OAuth token refresh worker, 48-node AI receptionist router. Real production patterns, not tutorial code.

Hi, I'm Christopher — a mechatronics student in Malaysia who spent the last year shipping a multi-tenant CRM in production. ~30 n8n workflows built: a message debouncer for WhatsApp burst traffic, an OAuth token manager that survives Cal.com refresh races, a router agent that classifies inbound intents. I focus on the parts of automation most freelancers skip — retry logic, idempotency, race conditions, OAuth refresh under load. Stack: n8n, Supabase, React, TypeScript, Cal.com, WhatsApp Business API, Claude/OpenAI APIs.
