At Auctane, I had a Sr. Engineer who was very harsh with Jr. Engineers in giving feedback. This led to Jr. Eng afraid of approaching with advice and team morale go down and productivity was down by 10%. I had to coach this teammate to not be hostile and instead approach people with Empathy and show ledership in asking the right questions and help them grown in their carrer as well - with this change in attitude, I saw that the team gel much better and the productivity increased overtime.

At Auctane, I had a senior dev working on tech debt, this was critical for some small segment of customers and my PM was looking forward to it being devliered. A churn happend on other team and they had a higher priority project. That EM approaced me to help him deliver the project. I had to reshffle the resource and had to push back on the timing for this tech debt project . The compramise I made was to put hold the project we had been working and convince my PM that this was most optimal approach for the company.

while reviewing one of the older projects that was currently implemented in the company I noticed that there was no alerting in place if the data pipeline breaks, the data pipeline has never been broken and it never failed for the last 2 years. it was a pipeline where the data would be dropped into an sftp bucket by the customer every hour and then it was moved to an s3 bucket where s3 triggers were implemented to moved the data in to queue. So in case there is an issue with the data not being processed we would only know when the we see a drop in volume. I identified it as a potential issue with the system and worked on a proposal to have monitoring in place so we are notified when there is an error. I worked with the program manager and devised a plan on how to implement the alerting and the time lines as well as the effort that will be needed to implement it. I mapped the impact of not having it to the current goals of the company and then put forward a proposal of implementing the alerts to the business and took their buyins. after getting the buyins I proposed the task to my team and some of the sr devlopers were not too keen on implenting the alerts, I gave the task to some of the Jr devlopers and the alerts were implemented. after the implementation we discovered that for some hrs in a day we werent getting any files so instead of getting 24 files in a day we were getting 20 files a day in an average. This was rectified by talking to the customer and the missing data was solved. but this made the whole team realize the importance of monitoring and alerting. It also bosted the moral of the Jr developers seeing the direct impact they made to the business goals

So I'd say the time I took the risk was, I actually went against the recommendation of my manager. Not directly, but essentially I was put on a project at Niagara and I was looking at a lot of the contract amendments and I analyzed our contract negotiation with Uber. And so as I was looking at the whole data, trying to see the discrepancies and really seeing, okay, what lanes should we negotiate, seeing what are the terms of negotiation that we should use, and then finally, I wanted to also forecast on terms of a long-term growth. So not just necessarily for just this term, but see how that would last for the future quarters as well. So kind of taking those into consideration while I put them all out into a matrix and showed the team, the director, and a lot of my team was thinking that we should go with the option that saves us the most amount of money. I'll put the $700,000 to $800,000 for the quarter, implementing this new amendment that I actually disagreed. And I suggested we just take somewhere closer to about the $600,000 range because for two reasons, one, I noticed that the lanes that we included in the $600,000 would lead to better client relations with Uber as a long-term and one of our biggest carriers. And two, I also noticed that in the long run, we actually would save a little more just because in the future quarters with seasonality to keep into account, those lanes were not always going to save us the most amount of money. So maybe while the $700,000 to $800,000 option would save us that much in the first quarter, when it comes down to the winter, it would save us only about $300,000 versus the $600,000 option is a little more consistent throughout the seasons. And so we actually noticed that in terms of a long-term growth for the year, we would save a lot more. So that was a time where I kind of took a risk to go against and maybe recommend something slightly different than my manager. But I think the director, when he heard me say these things, he took those into consideration and saw my analysis and saw that I was able to back up kind of my decisions and this type of risk to making sure I'm minimizing it as much as possible. So I think that was something that he really appreciated and that the VP of supply chain ended up deciding to work towards.

In my role leading the launch of that new customer onboarding system, the pressure was really on. We had that tight three-month window and a lean team to build something that would be the first impression for all our new users. One specific hurdle we faced was integrating our legacy customer database with this brand-new system. The data structures were quite different, and initially, the data migration process was proving to be much slower and more error-prone than anticipated. This threatened to push our launch date.

To tackle this head-on, I didn't just delegate. I dove into the technical details with the lead engineer. We mapped out the data fields meticulously, identified the key transformation rules needed, and actually prototyped a more efficient data migration script using Python. This allowed us to automate a significant portion of the process that was previously manual.

Furthermore, to ensure we were building the right thing quickly, we implemented very short feedback loops. We'd build a small piece of the onboarding flow, get immediate feedback from a small group of internal users, and iterate based on their input. For example, early on, users found a particular step in the registration process confusing. Based on their feedback, we completely redesigned that screen within a couple of days, leading to a much smoother experience.

By getting into the technical weeds to optimize the data migration and by relentlessly focusing on user feedback through rapid iterations, we not only overcame the risk of a delayed launch but also delivered an onboarding experience that was significantly more user-friendly than initially envisioned. It was incredibly rewarding to see new customers move through the system so smoothly right from day one. That success really underscored the power of combining technical problem-solving with a user-centric approach
