“In my last project, I worked on an automotive web application that handled campaign data processing and file integrations with external partners through SFTP.

One of the main challenges was that many file-processing and scheduling activities were still done manually. During high-volume campaign periods, this created delays and increased the risk of human error.

My role was mainly focused on improving operational efficiency and system reliability. I worked closely with developers and the operations team to analyse the workflow and identify areas that could be automated.

I used PowerShell and Windows Task Scheduler to automate file processing and scheduled jobs, which significantly reduced manual work and improved consistency. I also handled secure SFTP integrations using Bitvise and AWS Transfer Family to improve file-transfer reliability.

In addition, I used AWS CloudWatch and New Relic for monitoring and issue detection, helping the team respond faster when problems occurred.

Overall, the improvements helped reduce operational errors, increased system reliability, and supported smoother campaign execution for the client.”

“One of my greatest achievements was improving the scalability and performance of a forecasting system in my previous project.

During peak business hours, the system started slowing down significantly, which affected user experience and raised concerns from the client. My responsibility was to identify the root cause and improve the system’s reliability under high traffic.

I used AWS CloudWatch and application logs to analyse performance bottlenecks and found that several APIs were processing large amounts of data synchronously, which caused delays during peak usage.

To improve this, I implemented asynchronous processing, added caching for frequently requested data, and supported scalability improvements through load balancing and horizontal scaling.

As a result, the system scalability improved by around 70%, and performance during peak hours became much more stable. This not only improved user experience but also helped restore the client’s confidence in the system.

What made this achievement meaningful for me was seeing how technical improvements could directly create business value and improve operational stability.”

Suggested 1-Minute Version

“One example was when I needed to quickly learn tools related to SFTP integration and job automation in my last project.

At that time, many file-processing activities were still handled manually, which caused delays and occasional errors during busy campaign periods. I was responsible for helping improve the process, even though I initially had limited experience with tools like AWS Transfer Family and automation scripting.

I approached it by first understanding the overall workflow and identifying where automation could create the biggest impact. Then I focused on learning the specific tools through documentation, hands-on testing, and small experiments before applying them to real use cases.

I also collaborated with teammates to validate the approach and make sure the solution matched operational needs.

Within a short time, I successfully automated several important processes, which reduced manual effort, minimised errors, and improved reliability for the team.

This experience taught me that being adaptable and willing to learn quickly is very important in software engineering, especially when solving real business problems.”

Suggested 1-Minute Version

“I see disagreements as a normal part of teamwork, especially in technical discussions where people may have different priorities or concerns.

In one of my projects, we had a discussion about whether file processing for campaign data should remain manual or become more automated. Some team members preferred manual handling because they wanted more control, while I believed automation could reduce errors and improve efficiency.

Instead of pushing my idea directly, I first listened to their concerns and tried to understand the risks they were worried about. After that, I shared my perspective using examples of delays and manual errors that were happening in the existing process.

To make the discussion more practical, I proposed a gradual approach by automating repetitive and low-risk tasks first. I also created a simple prototype so the team could better visualise the solution.

As a result, we agreed on an incremental implementation that reduced manual effort and improved reliability while still maintaining visibility and control for the team.

For me, good teamwork is about listening, collaborating, and finding solutions that everyone can support.”
