About Vishesh Singh
As a Software Development Engineer II at Amazon, I contribute to designing high-performance, distributed systems, focusing on optimizing latency, scalability, and cost efficiency. Recent projects include launching a next-generation cold storage system (2.0) with zero downtime, resulting in $600K annual savings and 22% improved GET API latencies, as well as developing a concurrency-safe library that reduced weaving latency by 70%. With a Bachelor of Engineering in Computer Science from Chandigarh University, I bring expertise in systems design, Core Java, and AWS solutions. I am motivated by building resilient systems that deliver measurable impact, including cost reductions and performance enhancements, while collaborating with teams to drive organizational adoption of innovative solutions.
Experience
Software Development Engineer Ii
Dec 2024 — Present · Gurugram, IN
Cold Storage Migration Launched 2.0 storage for legacy service and migrated 185k TPS live traffic from 1.0 to 2.0 storage system. Used DynamoDB for offset storage and AWS S3 for blob storage, employing data batching to lower PUT costs. Implemented Coral APIs for 2.0 storage to support both 1.0 use cases and 2.0 datatype needs. GET API latencies improved by 22% and achieved $600K YoY annual savings through optimised storage migration. Mercury Library Proposed and developed a wrapper library for parallel execution of operations on the ER model, addressing thread safety issues in the existing data model by implementing custom concurrency controls. Initiated organization-wide adoption of the new library to enhance operational execution speed. Reduced weaving latency by 70% within the team for GET APIs using Java synchronized blocks and Executor Service. Improved business-critical SLAM latencies by 12% in Shipping Org, exceeding the VP-level goal of 10% reduction.
