Custom Development

Lab-grade engineering for your business automation.


Jimolab LLC operates 5 in-house SaaS products (realingo / lookupai / locatax / zeus-code / Promtect) and also takes on custom development for SMBs. Our chemistry-trained founder is involved in every architecture decision, so we ship things that actually work in the field.

What we deliver


AI agent implementation

Production-ready agents combining Claude / OpenAI / OpenRouter, with Slack / Teams / LINE integration. We bring real operational know-how from running 5 SaaS products in-house.

Internal SaaS

Admin panels, workflows, document export, and Stripe billing — end to end. We choose Astro / Next.js / Django stacks based on what is easiest to operate.

Data pipelines

Tying together spreadsheets, business systems, and external APIs to deliver auto-journaling and auto-reports. Daily batch jobs run on GitLab CI and k3s.

Landing pages & corporate sites

Schema, llms.txt, Lighthouse measurement included. Generative-AI search visibility comes built-in thanks to our lookupai (GEO/AEO) playbook.
