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.

Freelance Ruby Developer - Moiz Rizvi
Freelance Ruby Developer

I believe no technical problem is too big or too small if it makes an impact on the lives or business of others. I'm something of a bug exterminator and find a lot of enjoyment in fixing things, almost as much joy as I find in building fast MVP's for real-world problems. For the past 8 years, I've shaped and built production-scale apps on web and mobile for early-to-mid stage startups, 3 of which went through YC and were well-funded. I've worked on engineering teams at companies as big as Uber and Salesforce, and as small Spiceworks (~300), Umbel (~30), SparkCognition (~12), and TrustedFor (3), myself being the first employee. I also worked as a Product Manager for Gigster in its first year taking over 50 projects to successful completion before starting my own agency.

Freelance Ruby Developer - Tyler Green
Freelance Ruby Developer5.0 (4 reviews)

Hello, I'm Tyler! With a Bachelor's and Master's degree in Computer Engineering and over nine years of experience in the tech industry, I bring a wealth of knowledge and expertise to the table. I have worked on professional projects such as using Ruby to process x86 assembly instructions and using Python and React to show public transit arrival times. My experience across stacks and domains has led my passion to grow beyond just "getting code to work"; it's about unraveling the nuances of how software functions and exploring each layer of its construction. Throughout my professional career, I've taken immense joy in mentoring fellow engineers. Not long ago, I helped a junior engineer migrate some data processing code from a React Native application to a Kotlin application. This not only solidified their understanding of frontend versus backend development, but also enhanced my skills in explaining technical concepts in an accessible way. I approach teaching from a "First Principles" approach: if we can step back and understand the foundations underpinning each subject, we can dive into the details of a task or project with more confidence and resilience. I'm also excited to introduce a new guided Rust HTTP server project, which provides a deep dive into how an advanced library, similar to Axum, works under the hood. Over the course of five sessions, you'll gain hands-on experience in building a performant HTTP server from scratch, learning key concepts in Rust and network programming along the way. Lastly, I view code as a creative pursuit. Is it art? That's in the eye of the beholder. Having something functional is an critical step, but producing something clean and that you are proud of is my north star. I invite you to contact me with any questions or to discuss your specific learning goals. Let's work together to build your understanding and confidence in software and computer engineering!

Freelance Ruby Developer - Calvin Conley

I’ve previously worked as an English tutor and enjoyed helping students improve through 1:1 sessions.

Whether you're stuck on a project, learning the basics, or preparing for your first developer job, I'm here to help you succeed.

Freelance Ruby Developer - Ikechukwu Orji
Freelance Ruby Developer5.0 (143 reviews)

I dwell in the midst of complex problems. I make my bed with solutions to problem. Have built solutions ranging from complex stocks management system with realtime stock data synchronisation to web applications that manage and analyse user data in their millions. In summary, I love seeing problems solved. I am also a debugger tool (kind of) and a teacher. I spot and easily detect bugs lurking in your code within minutes. I specialised in Javascript, but you would find me working with ruby, python, Go and even dart. Would love to help out with your project and help you find those solutions that have proven difficult, together we can bring walls down.
