I have a master's degree in information and computer science from University of Michigan. I've been working as a software developer in the Defense sector since 2005 with a shift to web development in 2014. I've also had a passion for teaching, providing tutoring for programming students at a local boot camp, Grand Circus as well as online at tutor.com. Students have told me that I'm good at breaking down complex subjects for them, being patient with them and helping them learn.

I enjoy helping people understand how to solve problems and learn, and I have been tutoring for a while, but I have a limited number of students and would like to increase my workload. I would like to assist more students in becoming proficient in programming.

With over 25 years in the software industry, I bring a robust mix of hands-on engineering and management expertise. Currently, I lead the teams for Gemini Code Assist at Google, where we develop and scale backend systems and extensions for both VSCode and IntelliJ to deliver high-performance code assistance. As a startup founder and an innovator, I enjoy wearing multiple hats, diving into new technologies, and taking prototypes from rapid development to production-scale systems. Proficient in over 15 programming languages, I primarily focus on JavaScript, TypeScript, Node.js, Electron, and Web technologies, with occasional use of Python. My approach is rooted in scalable solutions and inspiring teams to deliver impactful results.

Freelance Ext JS Developer - Konstantin Yegupov
Freelance Ext JS Developer5.0 (8 reviews)

Professional Software Developer since 2005 (and been excited to build software since 1991). I specialize in web applications and backend services, although I also dabbled in frontend development, data science and signal processing. After working for small companies, I have learned to produce quick and efficient prototypes from not-exactly-clear requirements. After working for big companies (Google etc), I now have a passion for developing clear, reliable and highly maintanable solutions. I also excel at debugging and solving extremely complicated issues that arise in big production systems. I'm great with Python, Java, JavaScript and Go - and I'm also a quick learner, constantly adding new technologies to my tool belt.
