ABOUT ME
Software Engineer
Software Engineer

Sr. Frontend Engineer with 9+ years of experience helping startups and mid-sized companies to materialize ideas into web applications. I have a strong passion for software development and solving complex problems with clever solutions.

The company where I experienced the most significant growth was Courskey. The primary factor behind this growth was my deepened understanding of the software development cycle and the essence of being a Software Engineer. I realized that proficiency in a specific framework or programming language mattered less when you grasped the core principles of programming. This insight made it easier for me to adapt to and learn new technologies.

Some of the projects that benefited from my contribution are:

  • Developed a set of onboarding pages for Mora Medical, resulting in a remarkable user growth of over 5,000
  • Collaborated on a student attendance solution for Courskey, a feature that played a crucial role in securing a $1 million deal with California Campuses.

My co-workers would likely describe my strengths as: approachable, a positive and energetic attitude, strong leadership skills, and a genuine willingness to support others.

Came to Ethan to implement a React UI from scratch. He is very knowledgeable about React and its ecosystem. He communicates well, is a quick and pragmatic developer. Have had 5 one hour long sessions and will likely have more. Recommend him for any React work.
