Freelance Ruby Developer5.0 (5 reviews)

GitHub: https://github.com/waynel LinkedIn: https://www.linkedin.com/in/wwwayneliu/ Note: For the past 18 months, I've been heavily focused on AI Engineering and AI-augmented Software Engineering - building features that use large language models (data entry automation, retrieval augmented generation and text-to-SQL chatbots) and experimenting with AI tools to improve my engineering workflow. I've been working as a software engineer for 10+ years that has been mainly focused on web application development and some systems development, in NYC and Boston. Have had full-time roles at 4 startups and 1 corporation. I come from a strong computer science background, having graduated from Carnegie Mellon University. My experience lies both in computer science fundamentals and shipping projects end-to-end as a full stack generalist - frontend, backend, data, and SRE. Having worked at startups, I've learned to be versatile, doing some minor product and project management as well. In addition, I've launched 3 full stack side projects. With 5 years of experience mentoring other engineers, I've conducted 50+ technical interviews and have been interviewed 20+ times. I enjoy helping others - it's fulfilling to help others level up while also helping my own continuous learning! Some potential areas I can help with: - brushing up on computer science fundamentals - preparing for software engineering interviews (data structures and algorithms coding problems, system design, behavioral) - pair programming on a project, recommending best practices for frontend, backend, data, and SRE - code review - debugging - testing - resume review - career strategy consultation

Freelance Ruby Developer - Vedad Fejzagic
Freelance Ruby Developer

As a seasoned back-end Developer, I excel in crafting robust solutions that drive impactful results. My journey with Computer Science started early, during high school, where I honed my skills through participating in C++ competitions. Years later, I progressed from an intern to Senior Software Engineer and in the process, mastered Ruby, Nodejs, Java, and Scala, leveraging both noSQL and SQL databases along with tools such as Docker. I thrive in complex environments, as demonstrated by my work on back-end microservices, enhancing API efficiency through parallel computing. My expertise in Java and Scala was pivotal in advancing a multi-client back-end project, where I also mentored engineers. Even though my proficiency and expertise is mostly back-end oriented using Java, I am able to develop solutions based on a wide range of other technologies as well.
