About | Sunil Kumar

7+ yrs · MIS & Automation

Hi, I'm Sunil — an MIS Manager turned independent developer, with 7+ years of experience in automation, data management, and ERPNext customization. I specialize in streamlining business processes using Google Apps Script, webhooks, and APIs to cut manual work and boost efficiency.

I've led teams building data-driven dashboards in Looker Studio, integrated Facebook Lead Forms directly into ERPNext, developed WhatsApp chatbots, and automated leave and incentive systems — each cutting manual tasks by over 40%.

Today I work directly with small businesses as an independent developer, taking a process from "we do this by hand" to a system that runs on its own. Explore what I've built below, or reach out if your team has a process worth automating.
