A Little About me

Profile Image

Hello, I'm Tanner! I enjoy building things for the web. One thing I have always enjoyed is the ability to bring ideas to reality through code and express those passions through my work on the web.

Right now I currently work at Visa on their Data Platform team building web applications that help data engineers design, build and scale data engineering tasks and workloads at massive scale.

Outside of what I do at work, I am very passionate about learning and teaching others about software engineering and web technology as well as learning about product design.

Below are some of the technologies I have experience with

What They're Saying

Greg Bernstein
Professor at CSU East BayProfessor for undergraduate and graduate level web development and systems courses

Tanner was one of the top students in my CS351 Web Development class at California State University East Bay. This class was on full stack web development which includes development for the front end, backend, and the network (protocols and architectures). Tanner excelled at Website design, React, and Node.js development. As an undergraduate he then took my graduate level CS651 Web Systems class where he was my top student. This class featured enhanced web security, server testing (via JavaScript testing frameworks), enhanced JSON processing including JSON-Schema based validation and WebSockets.Tanner went significantly beyond class requirements with his own development project (web app) which featured independent deployment, API usage, enhanced CSS techniques, etc. In addition, Tanner has very good communication skills. I highly recommend Tanner for any type of web related development job

Karan Monga
Software Engineer at Apexx StrategiesFormer classmates and developers on senior capstone project

I had the pleasure of working with Tanner on the Frontend team for the class project during our Software Engineering course. Tanner always displayed enthusiasm to learn new things and motivated the team to do a better job. His experience in JavaScript programming proved valuable during the development phase. Above all, I was really impressed with Tanner's quick learning ability and his dedication to the task at hand. I highly recommend him for any Frontend developer position

Joshua Knudsen
Fomer Student at CSU East BayFormer classmates and developers for numerous projects in school

Tanner is a very hardworking student who is very passionate on learning the material and takes joy in helping others around him understand the material. He puts a lot of time into understanding and practicing material learned in class. His knowledge of Python reflects the effort that he puts in
