I led a project to implement a new feature in our loan processing system aimed at reducing API latency for faster loan approvals. Midway, I encountered data inconsistencies and latency issues caused by schema mismatches between the new API and our backend services. To resolve this, I optimized the data schema mapping, streamlined query performance, and introduced Redis caching for frequently accessed data, which significantly reduced the API call frequency and improved response times.

I also collaborated with QA to parallelize testing, allowing us to catch issues early. By continuously optimizing our microservices with adjustments to load balancing and asynchronous data processing, we increased processing speeds by 20%. While the deadline was slightly extended, our enhancements directly improved loan approval times and were a solid technical win for both the team and the user experience.

i was head of events in a student activity called aces and it was a magnificent experience as i gathered a team wich i chose by myself and my partner as they all were hardworkers and creative thinkers of course we had some trouble with them as some of them were being lazy about doing there tasks or procranstinating but we were able to motivate them each time so they would give their best

I was having a team member, who was technically strong, but when it came to gelling with the team members, he was having problems. His comments/feedback for the technical artefacts, or for ones understanding of a problem, was showing people in a bad light. Team members were apprehensive, working with him. People started to unplug themselves while that person was around. I could sense that, the team’s engagement had started to wane. If that had continued, we were at risk of losing that person from the team.

I initially un-plugged him from the team discussions and meetings and started to have a daily sync-ups with him. Sensitised him about working as a team and how successful teams thrive in the organisation. Made him enrol for some trainings like - Seven habits of highly effective people. Recommended that training mainly because of the focus it lays on - personal change, collaborations with the team etc.

Then he started to show empathy towards the team members, started to mingle with team, started to give constructive feedbacks for the technical contributions and started to show respect to the fellow team members. The bridge that was created, started to disappear. And we finally made him part of all the discussions and meetings and today, he is one of the go-to person in the team.

During final stages of testing upgraded version of core banking applications, we encountered a defect which required resolution from development team. After dev deployed the defect, I had very limited time to thoroughly retest and perform regression.

My task was to perform retesting and make sure there are no major defects after the release.

After resolution, based on my prior knowledge of the apps I grouped those testcases that had a potential impact to run automation regression to speed up the testing. While I manually tested the defects with some edge case scenarios. 

I kept the cross functional team updated about the testing progress and the risk involved if testing wasn't completed on time. 

But, I was able to mitigate the risk of not completing the testing on time and major risk of unexpected issues with the help to prior knowledge and proactive communication.

Thus, I learnt from this incident to carefully strategizing the situation and collaborative approach can help to mitigate risks.

I was working on a high stake project with very high visibility from my senior management.

Me and my manager were thinking of can we leverage the quality of the development using help from QA team. He wanted to keep the QA team separate. His point of view was that a separate team would keep clear focus for the team and they would focus on finding more customer facing bugs. I thought that we should have QA embedded in the scrum team as that would help in easier collaboration and quicker bug fixes plus this is a more efficient way. Though I understood his point of view I always believed that in QA embedded inside the scrum team. I went back had a thought to measure the merits and demerits of the proposals. I put down in a slide the merits and demerits of each. Merit from having a separate team, clear focus and better filtering of quality, demerits less collaboration with development team. I then proposed that the QA engineers attend the calls of dev teams but keep a separate QA board for their tasks. This will give clarity of what bugs they find, what test scenarios they create and finally the metrics to measure the bugs reported per development. My boss and I both agreed as it solved the problems of each proposals
