Andrii Zelenets

Who am I?

I'm a Full Stack Software Engineer with 12+ years of hands-on experience building scalable, user-focused web applications — from MVPs to enterprise-level systems.

I thrive at the intersection of technology, business goals, and user experience.

My specialisation is transforming ideas into reliable, maintainable, and high-performing software solutions.

Whether it's architecting backend systems, optimising frontend performance, or leading cross-functional teams, I bring a strong technical foundation and a laser focus on delivering value.

• Proven track record across industries like e-commerce, biotech, education, SaaS, travel, media, advertising, and social platforms
• Expert in Ruby on Rails, React, AWS, Stripe, GraphQL, REST APIs, and microservices
• Skilled in agile development, CI/CD, performance optimisation, and mentoring engineers
• Passionate about clean code, efficient architecture, and meeting deadlines without sacrificing quality

I believe technology should always serve the user and the business — not the other way around.
