19 Nov Co-Op Spotlight: Yiting “Miya” Guan

Posted at 19:34h in Blog by

This fall, we’ve had the pleasure of welcoming Yiting “Miya” Guan, our Northeastern University Co-Op, whose internship with us wraps up in mid-December. Miya is a Senior majoring in Accounting at Northeastern University and will be graduating this Spring. A dedicated student and hard worker, she has earned a spot on the Dean’s List and was a winner of the Supply Chain Simulation, highlighting both her academic excellence and analytical strength. After graduation, she plans to continue her education in Grad school.

This is Miya’s second Co-Op, and she has quickly proven to be an invaluable member of the Siegel Solutions team. She has supported our general Accounting function on the ongoing side while also playing a key role within our Professional Services team. Miya assisted with QuickBooks software migrations and integrations and has provided technical support for clients using QuickBooks and various third-party applications. Her willingness to learn, attention to detail, and client-focused mindset have made a meaningful impact across departments.

Originally from Shanghai, China, Miya completed all her pre-university education there and is the middle sibling between an older sister and a younger brother. Outside of academics and work, she enjoys traveling, hiking, and going to the movies, always ready for her next adventure.

Miya has been a joy to work with and get to know and we are grateful for all of her contributions this semester and proud to feature her in our Spotlight this month! Thank you, Miya, for your hard work, positivity, and commitment—you’ve been a wonderful addition to the Siegel team, we are going to miss you but know you will do great things!

Feel free to reach out to Miya here!

Mike Derrico
IT

I started my career in 1983 when I designed and built a device to share a computer program, written by the president of a local bank and his son, running on an Apple Lisa computer. The device allowed the large and expensive Lisa's computer to be shared with bank employees. With this program, and with my device, we started a company to market this unique solution to banks. At this point, computer networks were just starting to be used in businesses. I transitioned my efforts to providing support for migrating banking terminal/mainframe functions to the emerging Personal Computer networking platform. For the next decade, I worked with, and beta tested, numerous technologies to integrate the banking functions from dumb terminals into the now smart desktop computers. After working with a few small consulting firms, I started my own company focusing on providing I.T. support to SMBs. More recently I am now doing the exact opposite by helping customers migrate their PC applications and data from their local computers to The Cloud. A few years ago, I joined Siegel Solutions to add my years of I.T. experience to their firm.

In my spare time, I like to travel, fly my drone and, most importantly, spend time with my family. I also still enjoy tinkering with technology.
