I have successfully led the development of complex, full-stack systems, notably integrating Large Language Models (LLMs) at UiPath to automate test cases, resulting in optimized processes and a 40% reduction in redundant storage. I have enhanced global usability by designing a default timezone service, improved user experience by revamping the UI, which increased satisfaction by 25%, and ensured zero downtime as the Designated Responsible Individual (DRI) in production environments. Additionally, I played a key role in onboarding interns and integrating Redis Cache in the Test Manager service, reducing latency by 50%. At Trexquant, I developed quantitative trading strategies that boosted alpha returns by 7% on average, and conducted comprehensive backtesting to ensure robustness. My expertise spans backend and frontend development, API design, automation, and system optimization, consistently delivering high-performance, scalable solutions.
