Senior Backend Developer specializing in scalable software solutions.
What I'm looking for
As a Senior Software Engineer with extensive experience in backend development, I have a proven track record of designing and implementing robust systems that enhance operational efficiency. At TestSigma, I spearheaded the development of an Accessibility Testing Platform, ensuring compliance with WCAG guidelines across multiple platforms. My efforts in optimizing the Salesforce Object Metadata synchronization service led to a remarkable 40% reduction in sync completion time, showcasing my ability to drive significant improvements.
Previously at Ola, I played a pivotal role in implementing a demand aggregation strategy that reduced order drop-off by 25%. My work on the hop-ride system and the penalization system for drivers not only improved user experience but also enhanced operational metrics. I also built a feature store platform that provided real-time and historical data for machine learning pipelines, demonstrating my commitment to leveraging data for better decision-making.
My journey in software engineering began at WanderTrails, where I contributed to optimizing routing systems and integrating various services. With a solid foundation in Java and a diverse tech stack, I am passionate about creating innovative solutions that meet user needs and drive business success.
