招聘 principal / staff Ruby on Rails 开发者

My most recent adventure in Rails involved building a real-time visualization feature, powered by Rails 7 and Hotwire technology, for a remarkable number of concurrent consumers. That project proved the productivity and low maintenance burden of applications built with Rails 7, AnyCable, Turbo, Tailwind, and Stimulus. I have experience in all areas of full-stack application development. I have used Terraform to create Kubernetes clusters in the Google Cloud Platform, built data pipelines with Kafka and PostgreSQL, and, of course, created and maintained production Rails-based applications from Rails 2 to 7. I currently build web-based applications with NestJS (Node) and React via Typescript. I am particularly proud at how quickly I am able to adapt to different paradigms and techniques. Take a look at my Github, I also have experience in Elixir and the Phoenix framework. I’m learning Swift; all to say that I’m always eager to improve my craft through any type of project.

A passionate software engineer with the growth mindset of an entrepreneur. I have experience building web applications with well-known frameworks, including Ruby on Rails. I've been lucky enough to build integrations with many third-party API's including: Stripe, Zendesk, Facebook, Airbnb, Expedia, MailChimp, PayPal, Twilio, Segment, Twitter, Booking.com, Securities and Exchange Commission, and more. I have a high bias for action and like to move quickly and iterate. I'm a patient communicator and introvert. I'm a hacker at heart and like finding creative ways to push business to the next level.

With 9 years of engineering excellence across diverse domains, I've mastered the art of transforming complex challenges into elegant technological solutions. As the creator and maintainer of the Solid Queue Monitor gem(https://rubygems.org/gems/solidqueuemonitor) —a zero-dependency monitoring solution for Rails background jobs—I've demonstrated my commitment to improving developer tooling in the Ruby ecosystem. In my current role as a Staff Engineer at Torch.io, a coaching platform trusted by industry giants like Stripe, LinkedIn, Airbnb, and TripAdvisor, I've revolutionized support systems by implementing OpenAI's GPT-3.5 for email automation, reducing manual intervention by 48%. I've also leveraged AWS Bedrock with Claude 3.7 to generate organizational insights reports, improving decision-making efficiency by 40%. My technical versatility spans the full spectrum of development—from crafting robust backends with Ruby, Go, and Python to building responsive frontends with React, Angular, and TypeScript. I've engineered large-scale data applications handling 5+ million active users and orchestrated seamless migrations of 4.5 million records while maintaining system integrity. Throughout my career, I've delivered impactful solutions across multiple domains—enhancing FinTech security protocols, optimizing CMS performance, and elevating coaching platforms. This domain versatility, combined with my technical depth and AI integration expertise, allows me to bring a unique perspective to every project and consistently deliver transformative results.

Rails architect with UX fluency, blending 20+ years of technical mastery with design thinking. Specializing in microservices, AI, and data platforms, I build developer-first solutions that scale.

I am an experienced senior engineer with more than 8 years of industry exposure. I love to help entrepreneurs build and launch their startups and projects with full technical ownership. I have helped multiple aspiring founders by building their products: - https://sponsorless.com - https://devtree.app - https://getrecognise.com I primarily work with: - Ruby on Rails - Hotwire - Postgres - TailwindCSS - Sidekiq - Redis - Docker - and much more I also have experience working on several third party API's like Shopify, Stripe, DNsimple and AWS.

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.

Available for full-time positions.

I’m a product-minded developer who builds with the business’s needs front of mind. Ruby on Rails is my tool of choice because it’s the fastest way to turn ideas into impact. Its opinionated structure enables consistent delivery and makes it easier to scale teams without reinventing the wheel. Over the past decade, I’ve led and contributed to projects that not only ship but drive significant business impact In one internal platform modernization project, leadership projected needing 16 full time employees after the rebuild. Four years later, the same team of four was still using the software productively saving the company 12 full time employees. I also look beyond the technical tasks to spot leveraged opportunities. On a recent project, I identified a low-priority feature that, if built more robustly upfront, could unlock internal productivity. That decision now saves every employee 30 minutes a day, which results in thousands of hours a year saved. I thrive when building internal platforms, business efficiency, and moving fast to get the business impact as quickly as possible.
