Case Study
Asana ticket communication loop
Built a four-workflow n8n system that keeps shared inbox requests, Asana tasks, email replies, and attachments connected in one trackable conversation.
Isaiah Ritenour
Systems Engineer · Acumatica · Data Automation
I build the systems layer that keeps operations moving.
I turn fragile handoffs, manual reporting, and disconnected business systems into reliable workflows. My work spans Acumatica ERP, n8n, SQL, Python, EDI, and the operational details in between.
10+ hrs
weekly manual reporting reduced through Python automation

02
Data
Reporting pipelines that replace spreadsheet drift
Developed pipelines around Acumatica OData feeds, pandas, NumPy, openpyxl, Flask, and SQL to parse files, transform data, generate Excel outputs, and make reporting repeatable.
03
Automation
Workflow automation between business systems
Designed automations for routine handoffs, scheduled processing, notifications, file movement, API calls, and exception visibility so recurring work can run without constant babysitting.
04
Integrations
Data exchange with fewer blind spots
Worked with EDI and integration flows where validation, mapping, monitoring, and clean error paths matter. The goal is always the same: fewer surprises after data leaves one system for another.
How I Work
Systems thinking, hands-on implementation.
I like work where the answer lives between the database, the ERP, the automation layer, and the people who need the output. That means I care about the query, the import, the endpoint, the spreadsheet, and the person who has to trust it on Monday morning.
My current work sits closer to systems engineering than traditional support: improving ERP behavior, cleaning up integration paths, automating repeatable work, and building the SQL/Python pieces that make business data easier to trust.

Contact
Need someone who can bridge ERP, automation, and data?
I’m always interested in practical engineering work: messy data, clunky handoffs, fragile reporting, and systems that need to talk to each other more clearly.
