About

I'm Akash Upadhyay, currently a SDE at Juspay, specializing in payments, PA/PG and fintech with over 4.5 years of experience. My expertise lies in designing and implementing transaction processing, reconciliation and settlement systems for payment aggregators, orchestrators, and gateways, managing millions of transactions from various sources, methods and types. I have a proven track record in handling diverse tech stacks(including Rust, R, python, js etc) and successfully leading the migration of entire systems to Rust Beyond backend development, I'm also proficient in frontend technologies like React, Rescript, and RShiny.As a Google Summer of Code contributor at INCF (The Virtual Brain), I'm passionate about open source. I've made significant contributions to projects such as Chromium, The Virtual Brain, and CVAT, with over 70 repositories available on my GitHub (https://github.com/Spectre-ak)Previously, I served as a Research Intern at Samsung (PRISM), where I developed a deep learning model for real-time anomaly detection in logs from distributed servers

The Virtual Brain (TVB) is a brain stimulation platform. It offers tools for computing, simulating and analyzing functional and structural data of human brains. TVB provides a graphical user interface (GUI) for using its tools for studying human brains. The platform supports importing data into TVB like projects, data structures etc. Since TVB provides various tools for studying human brains the platform is also accessible through REST APIs. Goal of this project is to create a new package which will consume TVB REST services and perform operations on it. The new python client will have features like uploading data into a TVB, data encryption and validation, BIDS compatibility check etc. Users will be able to use this python client to interact with a remote TVB server without using an active GUI.
Mentors feedback:
I believe Akash has done a great job during all iterations, showing proactivity by analyzing requirements very well, raising issues quickly and suggesting solutions. The implementation has been completed as planned, leaving enough time for testing, packing the module and writing documentation. Keep up the good work!
