Hire senior Ruby on Rails developers

What Makes Me Different: What distinguishes me as an engineer is my unique journey through financial systems architecture combined with a relentless focus on observability and quality. While most developers build features, I build confidence - creating systems where you not only know when something breaks, but why it broke and how to fix it. My engineering approach was forged in the high-stakes environment of processing $100M+ daily financial transactions, where 99.999% uptime wasn't a goal but a requirement. This experience taught me that truly resilient systems aren't just well-architected; they're well-observed, well-tested, and well-documented. I've transformed chaotic codebases into comprehensible systems by establishing monitoring standards, comprehensive test suites, and clear documentation that empowers entire engineering teams. Where I truly excel is bridging the gap between complex technical implementations and business value. While many engineers can build impressive systems, I create sustainable architectures that solve real business problems. At a major top 4 US Financial corporation, I didn't just modernize a Rails platform; I enabled new financial products that directly increased revenue while reducing fraud by 35%. This business-focused mindset means I approach engineering challenges not just asking "how do we build this?" but "why are we building this and how will it create value?" My passion for mentorship has led me to develop a framework for growing junior engineers that has consistently helped them advance to senior roles in half the typical time. By creating structured growth plans combined with hands-on pairing sessions focused on system design principles, I've helped eight engineers dramatically accelerate their careers. I believe that building great engineers is as important as building great software - both are essential for long-term success. What truly sets me apart is my ability to transform complexity into clarity. Whether it's untangling a legacy codebase, explaining technical constraints to product teams, or documenting intricate system interactions, I excel at making the complicated understandable. This talent for simplification doesn't just make me a better engineer; it makes everyone around me more effective.

Hi, I have 3 years and 10 months of experience working with Ruby on Rails, PostgreSQL, and Postman. I have hands-on experience deploying applications across staging, UAT, and production environments. I'm available to join immediately and thrive in roles that offer new challenges and opportunities to collaborate with others. I'm flexible with both remote and on-site work environments.

With 10+ years of Ruby on Rails expertise, I don’t just build applications—I engineer scalable, maintainable systems that solve real business problems. My journey began as a curious developer tinkering with Rails, and over the years, I’ve evolved into a problem-solver who bridges technical complexity with business value. One of my proudest achievements was optimizing multi-tenant database migrations by 75%, introducing rigorous security checks, automated code analysis, and comprehensive test coverage—ensuring reliability at scale. I’ve also turbocharged report generation by refining ActiveRecord queries and leveraging PostgreSQL optimizations, slashing load times while maintaining data integrity. Beyond coding, I thrive on efficiency and reusability. When integrating third-party APIs, I don’t just glue them together—I built my own Ruby gem to encapsulate logic, making future integrations faster and cleaner. Staying ahead of the curve is second nature: I run a weekly tech newsletter to keep my team (and myself) updated on Rails, Hotwire, and PostgreSQL advancements, ensuring we’re always leveraging the best tools. What truly sets me apart is my blend of deep technical skill and strategic thinking. I don’t just write code—I architect solutions that are secure, performant, and maintainable, while mentoring teams to raise the bar collectively. If you need a developer who ships high-quality software and elevates those around them, let’s talk. 🚀

Setup is mostly done via Ansible or manually over SSH. Projects I've worked on include: - Online community platforms - E-commerce SaaS - Business applications for real estate companies - City marketing platforms

Started at sixteen through curiosity and tutorials from simple HTML and CSS to frameworks. With the single goal of creating a start-up that was the dream.

👋 I’m a Laravel developer who loves building clean, scalable SaaS platforms and APIs. 🚀 I’ve led projects like multi-tenant payroll and modular LMS systems using TDD & DevOps. 🧠 I contribute to Laravel & Inertia.js and enjoy automating workflows with AI tools. 💡 Passionate about solving complex problems with elegant code and working async with remote teams!

Hi! My journey in software started during university, I have a bachelor's degree in Software Engineering and that’s where I had my first contact with Ruby, back when Rails was on version 3, during that time I co-founded a junior enterprise with some classmates. The idea was to apply our learnings building small systems for local businesses, using Rails, PostgreSQL, Heroku, and RSpec. And from there I never stopped learning, for the past 8 years I've worked in so many different projects for big companies like GoDaddy (U.S.A.) and Trainline (EU) and I'm sure I'll have many other challenges to overcome.
