Project details
You'll get a custom CRM app built on AppSheet with a Google Sheets backend — designed for your specific workflow, not a generic template.
I've built CRM systems for clients in manufacturing, distribution, consulting, and services. Each one is tailored to how the team actually works — contact management, deal tracking, activity logs, dashboards, and automations.
Every app is mobile-friendly, works offline, and your team can start using it immediately. No monthly software fees beyond Google Workspace.

Improvement of already developed BoM application in AppSheet
As this is a follow up contract, I already have successfully and happily worked with Islom before. He is always reliable, quick to answer when I sent spontaneous messages and proactively asked for updates or suggested changes that could improve the project. Would definitely recommend working with him.

People app
Islom has been working with us on developing our app, and the experience has been excellent. Islom is very cooperative, collaborative, and consistently available to resolve any issues or bugs. The app is now up and running smoothly, and we are very satisfied with their services. We highly recommend him.

The contract delivered good work on this AppScript development project and I enjoyed working with Islom. His communication was top-notch, he met all deadlines, and his skills were reasonably strong. Job well done

Web based AppSheet for BoM configuration and material tracking with Zapier connection to Salesforce
Worked with Islom on a project in Appsheet. The project took longer than expected, but not because of Islom's speed of working but because we were able to go beyond the original scope thanks to the progress we made. He always delivered on time or even quicker. Communication was easy and spontaneous meetings could always be scheduled at the latest the next day.
