Lead Software Engineer
2016 - 2019
FactSet
- Led three engineering teams across global offices to develop and maintain 10 applications in the portfolio analytics division.
- Initiated the project to create a unified web application, Portfolio Reporting Batcher, to replace four legacy batching applications, delivering a one-stop solution for clients' batching workflows.
- Designed a long-running infrastructure to offload Portfolio Reporting Batcher's complex operations to background processes, significantly increasing the success rate of job runs by 40%.
- Created a centralized Batch API to orchestrate and manage 50,000+ reports per job, reducing code redundancy by over 30%.
- Led the design and development of an automated conversion system to seamlessly migrate 10,000+ client documents and jobs onto the next-gen platform, saving product managers six months of manual work.
- Collaborated with project managers and other engineering groups to plan and prioritize projects for engineering teams.

Experience
A File Downloader Module for a Web Crawler
https://github.com/akabeera/file-downloaderA Python module that can be used on its own or integrated into a web crawler for downloading media from the internet. The file downloader supports various protocols such as HTTPS, FTP, and SFTP and even has an interface where consumers can plug in their custom modules.
The file downloader is very robust in that it's able to support huge files (50GB+ range) without timing out, it's ready to automatically restart a download in the event of losing internet connection, and it allows you to control the memory usage of each download.
It is also very configurable. You can specify the number of files to download in parallel, by size, and to break each file while downloading. You can also specify the max timeout for connecting to a server as well as waiting for server activity during a file download.
