Software Dev Engineer, Microsoft | Ex Amazon | IIT Kharagpur 2021

About

As a Software Dev Engineer at Amazon, I work on developing and deploying scalable and reliable microservices for Alexa, the voice assistant that powers millions of devices and interactions. I have a Bachelor's degree in Chemical Engineering from Indian Institute of Technology, Kharagpur, one of the most prestigious engineering colleges in India. I have over two years of professional experience in software engineering, having worked at Technoforte Software Pvt. Ltd. and National Yunlin University of Science and Technology, where I developed 3D visualization platforms for mathematical and vector calculus concepts. I have strong skills in Java, C++, Alexa, Game from scratch, C#, Xamarin, Flutter etc, as well as a passion for artificial intelligence and machine learning. I won the first prize in the AI Image Classification Hackathon organized by KSHITIJ, IIT Kharagpur and Affine Analytics in January 2020. I am a creative and collaborative problem-solver who strives to deliver innovative and user-centric solutions that enhance the lives of people and communities.

Work experience

Software Engineer at Microsoft, Jun 2024 - Aug 2025 · 1 y 2 mo, Hyderabad, Developed a cross-IHV insights portal usingDash + Plotly, featuring interactive dashboards and analytics UIs that let engineers compare WebGPU and PerceptiveShell profiling across architectures — cutting analysis time from hours to minutes and enabling environment-style reproducibility for testing and analysis. Implemented a heartbeat monitoring system in Python + Azure for scheduled health checks and instant email alerts — reducing incident detection time by over 90% and virtually eliminating unplanned downtime. Improved dashboard performance by 11× (45s → 4s) via threaded data retrieval, selective caching, and query optimization — significantly enhancing engineer satisfaction and adoption. Built a multi-workload profiling and testing framework to orchestrate workload execution, process results, and push structured data to Postgres(SQL) for self-serve analytics.

Professional development at Career Break, Sep 2023 - May 2024 · 9 mos, Kalyan, Maharashtra, India

Software Engineer at Amazon, Jul 2022 - Aug 2023 · 1 yr 2 mos, Engineered a dynamic response-building mechanism in Alexa’s backend that generates only required payload fields — reducing latency and memory usage under load. Modularized person object generation into a dedicated Spring component, simplifying code paths and enabling future extensibility with minimal refactoring. Redesigned speechlet payload creation with a directed graph-based execution model to enable parallel processing — reducing latency by 8 ms and increasing throughput during high concurrency. Managed high-priority Sev-2 incidents and escalations during office hours, ensured SLA compliance by prioritizing tasks effectively and maintaining stable queues.
