• ⏩ My role was to get it built and delivered. Stabilized system, improved monitoring.
• Role was just not limited to coding, but other aspects of the lifecycle as well. Mentoring, code reviews, managing the project cycle, system design, improving the monitoring system, debugging issues related to stability and scale.
• 🔥 I built a streaming pipeline which allowed exporting very large reports without primary memory constraints. I believe this got extended to other teams as well as it was featured in OYO's engineering blog

• Coming from a start-up background, my short experience at OYO gave me exposure to the functioning of an enterprise size tech-team which hustle at a startup pace. I first-hand get to see how things should be and what absolutely shouldn't be.
• The good - I didn't expect the DevOps to be publishing a monthly team wise expense split. Some top-notch unexpected stuff given that they were quite big.
• The bad - The work quality was sub-par
• The ugly - Devs were doing too much manual work.
• I was laid off under COVID-19 circumstances in mid 2020, since companies in the hospitality domain were majorly impacted.
