ABOUT ME
Full-Stack Engineer & Developer Mentor | Rails - React - Javascript
Full-Stack Engineer & Developer Mentor | Rails - React - Javascript

Hi, I’m a senior software engineer with over 15 years of hands-on experience building real-world web applications using Ruby on Rails, React, JavaScript (Node.js), and SQL. I’ve helped early-stage startups launch quickly, modernized legacy systems, and mentored hundreds of developers through their coding journeys.

Now, I’m bringing that experience to Codementor to help you level up—whether you’re stuck on a bug, building your portfolio, or scaling a startup.

💡 What I Can Help You With:

→ Debugging tricky Web development-related issues
→ Code reviews + clean architecture feedback
→ Designing scalable backend and frontend solutions
→ One-on-one mentoring & pair programming
→ Career growth guidance for developers (interview prep, resume reviews, etc.)
→ Building MVPs and making smart tech stack decisions
→ Writing developer-friendly docs & onboarding flows

🚀 Why Work With Me?

I’m friendly, patient, and laser-focused on helping you make progress. Whether you’re a beginner looking for clarity or a founder needing quick technical direction, I tailor my approach to your specific goals.

Let’s solve your problem together, and make sure you walk away smarter, faster, and more confident.

🙌 New to Codementor, Not New to Code

While I’m new to Codementor, I bring 15+ years of real-world experience in Rails, React, and full-stack development.

If you’re one of my first clients here, you’ll get discounted sessions, extra support, and a chance to help shape this mentoring space with your feedback.

Let’s ship great code together—and build something awesome.
