About Me

Hello! I am Aman Harsh. I am a graduate student at University at Buffalo, SUNY, pursuing a Master's degree in Computer Science & Engineering. I have worked as a Software Developer at GE Healthcare for 5 years where my work was primarily in the eCommerce domain. I have also completed an internship at Honeywell Technology Solutions where I have built an Augmented Reality application for Aircraft Maintenance Engineers.

My specialities include quickly learning new skills and programming languages, problem solving, working in an agile environment, object oriented design, and the MVC method of organising code. So far, I have Java, Spring Framework, MyBatis, Python, C/C++, ReactiveX Java, REST, Javascript, Apache Solr, Android, PostgreSQL, CockroachDB, MongoDB, HTML, CSS, JSP, Jenkins and Git/Github under my belt. I've started learning GoLang, React.JS and Machine Learning.

Few other software tools that I've gained hands-on experience on include Postman, Swagger, Retrofit, Ant, Maven, Gradle, Sonar and Adobe Photoshop.

I'm still enthusiastically grabbing onto any other programming languages, frameworks, or principles I can integrate into the coding web in my head. My career aspiration is to combine my knowledge and expertise in software engineering and build products and services that make a difference.

Research Experience

Projects

Dynamic Optimization of File Transfer in OneDataShare

Feb 2022 - May 2022

  • OneDataShare is an open-source tool for fast and secure file transfer with support for most cloud storage services and protocols like Google Drive, Amazon S3, etc. It aims to remove the burden of managing end-to- end data transfers from the shoulders of users.

    The OneDataShare Transfer-Service did not collect/report the network state that it experiences. We aimed to optimize the transfer by studying the networking conditions of ongoing data transfers. We change the optimization parameters of the ongoing transfer at runtime to improve the transfer rate. The parameters are fine tuned dynamically using a Bayesian Optimizer. Further, we also collect and report the state of the network to allow the user to understand the bottlenecks in their network.

Image Stitching

Nov 2021
  • Developed an application in Python to stitch images together to construct a panorama image.

Camera Calibration

Oct 2021
  • Implemented camera calibration on the given set of 3D points on a cubic chessboard. Used the OpenCV library to convert the image into gray-scale and then detect the corners. Applied the knowledge of linear algebra for solving the characteristic equation. The final goal of the project was to get the intrinsic parameters (focal lengths and translation) using camera calibration.

Covid Live Data Updates

Jun 2020
  • Created a python script to display a state-wise covid cases in India and represented the data in a graph.

Hybris Launcher
