The fuel sector might not seem like the most obvious place to look for innovation, but technology is quietly reshaping how things work there, too. From managing fuel pumps to tracking tank levels and offering loyalty rewards, digital tools like Java, AWS, and MongoDB are playing a more increasingly significant role.

A seasoned professional, Sasikanth Mamidi, whose work spans across cloud platforms and large-scale applications, has been central to these changes. As a Senior Software Engineer Lead who has been in the industry over 15 years, he helped build a Spring Boot application that runs on AWS Lambda and uses Kinesis streams to move data quickly and securely. The system uses MongoDB Atlas to store real-time data and has greatly assisted in reducing operating costs by 15%, while keeping fuel dispensers running 95% of the time.

He shared how serverless computing, where systems automatically scale without needing physical servers, has been a key part of this shift. One platform built with AWS Lambda and Amazon API Gateway cut infrastructure costs by 20%. It means better performance for less money-something every business aims for. But the impact of these initiatives isn’t just about reducing costs. Real-time event handling is a major requirement in this space. “With is kinds of feature implementation with this tech stack, we saved millions of dollars from Fuel thefts, almost 20% cost reductions in the maintenance of ATGs,” he added. “We also achieved to deliver accurate reconciliation reports, also we can send fuel sales report in terms of volumes and dollars on demand for all the stores.”

Another big improvement through the development of a mobile application that was built to let customers authorize pumps, fuel their vehicles, and get receipts-completely contact-free. “This was implemented at the Covid which helps the customers to reduce the contact to the pumps and also gave very exciting experience too,” he noted. The app also ties into a loyalty system where users earn points and get discounts based on how much fuel they buy. The company also replaced expensive third-party tracking devices with a cloud-based system. Before, they had to rent equipment just to read fuel tank data. Now, data is pulled directly from each location and stored in MongoDB, making it easy to generate reports, track inventory, and even detect unusual activity. This change alone led to a 15% cost saving, while also making maintenance easier and more efficient.

Additionally, the loyalty system has turned out to be more than a bonus feature-it’s a way to better understand customers. The backend can analyze fuel usage, suggest personalized offers, and send real-time promotions that encourage people to head inside stores after fueling up. The goal is not just to sell fuel but to increase overall business.

Mamidi also highlighted how none of this was easy. Before these systems were in place, most operations relied on manual monitoring or external vendors. It was costly and often inaccurate. Now, with cloud technology, the same tasks can be done faster, more reliably, and at a lower cost.

Looking ahead, there are even more possibilities. The next step can be adding AI to make fuel pumps smarter-turning them into kiosks where people can place orders, see personalized ads, or even pay for in-store items. With better cloud infrastructure, updates can roll out automatically, helping keep everything running smoothly across locations.

In short, the mix of Java, AWS, and MongoDB is helping the fuel industry run more efficiently and serve customers better. It’s a reminder that even industries that seem unchanged for decades are being reshaped by smart use of technology.
