JamesDev Systems

James Ten builds custom operational systems for small and mid-sized businesses that have outgrown Excel, WhatsApp and paper forms. Based in Singapore, serving clients in Singapore, the UK and the USA.

What I build

• Order, delivery order and invoice systems (logistics, distribution, contract packing)
• Purchase request, PO, goods received and payment approval workflows
• Leave and HR portals with Singapore MOM leave rules built in, each figure traceable to the rule
• Enquiry, job scheduling and follow-up systems for service businesses
• Multi-company portals: one system across several entities, with per-module permissions

How I work

1. A free 20-minute chat to see how you work today
2. A fixed price in writing within 24 hours
3. Built in phases, tested, and handed over. You own the code and the data.

You choose where it is hosted (your server, AWS or GCP). Built with PDPA and GDPR in mind.
