Niharika Hari

I’m a Software Engineer with 5+ years of experience spanning backend/full-stack engineering and automated software testing. I focus on end-to-end ownership across architecture, development, and deployment, with a strong debugging mindset for complex systems.

In my current role (JAN 2025 – PRESENT), I design, build, deploy, and maintain full-stack systems for data-driven simulation and decision-support applications. I developed a Flask-based simulation platform that runs system dynamics models via PySD and delivers results through Vue.js dashboards using REST APIs and Celery-based asynchronous processing pipelines.

I’ve also built low-latency, parameter-driven querying for ~2 million precomputed Vensim simulation runs stored in MySQL, and engineered distributed workflows and an offline-first architecture across internet-constrained environments. I supported live simulation execution across 10–15 connected systems for 40+ participants from 25 organizations, and deployed containerized applications using Docker on Linux-based infrastructure.

Previously (AUG 2020 – APR 2024) at Cognizant, I maintained and scaled test automation frameworks for desktop, web, and mobile applications, reducing execution time by 20% and cutting manual testing effort by 60%. I also improved API test coverage using Karate Framework and implemented parallel execution strategies that reduced automated test execution time by 70%.
