Hire principal / staff freelance Ruby on Rails developers in Canada

👋 I am a back-end Rails developer and data engineer who specializes in refining Rails applications to improve their performance, maintainability, and reliability. My methodology emphasizes efficiency and usability. My area of expertise lies in optimizing database performance, which includes data partitioning, query optimization, and index refinement. I've tuned PostgreSQL for high performance and I'm familiar with advanced tools like Timescale, postgis, pgrepack, and pgpartman. I am a big fan of using Sidekiq for managing background jobs within Rails applications. As a production engineer, I use CloudWatch, Datadog, Sentry, and Grafana/Prometheus to monitor system health in real-time, ensuring reliability and quick issue resolution. My data engineering toolkit revolves around PostgreSQL and the Kiba gem, which is complemented by Python data-stack technologies, Fivetran, Superset, and DBT. I am committed to an incremental development approach that balances team and customer needs, budget constraints, and project goals. I focus on creating sustainable, scalable solutions catering to evolving business requirements. I value clear communication and mutual understanding regarding role expectations and project objectives. To foster a transparent and effective working relationship, I prefer to share code samples and specific strategies only after thoroughly discussing the role and its requirements.

I've been working with Rails since pre version 1, and have always been a big fan. I appreciate clean, easy to read and easy to understand code. I have worked on many different projects from Rails 1-7, in every stage of development from greenfield to startup to legacy projects. I am a big fan of the recent Hotwire additions to Rails, and have worked on a number of projects using Turbo and StimulusJS. I am a full stack developer, but prefer to follow Rails standards and keep Javascript code minimal to maximize productivity. I am a strong problem solver and excel at designing systems and solving bugs. I really like to collaborate and create the best product possible.

I am a passionate technical expert, software craftsman, entrepreneur and mentor. I offer hands on experience in solving business problems, making software, and building engineer- ing teams that make software. I analyze business needs and take on the responsibility of ensuring strategically significant business results. I practice, implement and lead using proven software engineering techniques to ensure quality, accelerated delivery of working software.

Programming professionally for 20 years. I've spent the last 4.5 years as Backend Lead at Pexels, and previously held lead roles at HYP3R and TalentNest. Primarily interested in backend Team Lead or Engineering Lead positions. Looking for a fully remote role. I am very passionate about software engineering, writing maintainable, testable and clean code that follows good architectural practices. I began as a self-taught programmer as a preteen, and worked as a freelance developer through high school and university. That led to a career in multiple industries (including construction, applicant tracking software, social media and currently stock photography), and a fast rise from individual contributor to tech lead and beyond. In order to give back to the Ruby community, I began heavily contributing to RuboCop (a Ruby linter with 300 million downloads that is a key piece of the toolset for most Ruby developers), culminating being invited to become a core team member at the beginning of 2021. I have held lead seniority roles for more than 12 years. As a manager, I see myself as a developer advocate, and spend a lot of time focusing on the happiness and productivity of my staff. Currently I am the Backend Lead at Pexels. In this capacity at a small company, I have a wide variety of responsibilities, including: Architect, plan, implement, test and ship large complex features and build out process Help non-engineers plan, scope and estimate their projects and participate in organization-wide product planning Triage and respond to security issues in code and infrastructure, including running a bug bounty program Manage and mentor a team of backend engineers of all levels. Procure and negotiate with vendors, including saving the company tens of thousands of dollars in hosting costs Looking forward to hearing from you!

I am a self taught web developer with 17 years of professional experience. I started by building custom hand coded websites for many small businesses around Calgary, eventually went to Wordpress and other CMS, and then realized I needed something deeper, and started my full stack adventure. I have learned many languages and frameworks, and while I love Ruby for it’s conventions and amazing ecosystem, I love to dabble in new technologies and learn something new. My most recent new project is a windows app that will serve as a content creation toolkit for my website. (github) I’m looking for either a greenfield project, a legacy project that needs new features, or for short term, I am open to helping to revive a dead codebase.

I'm a Full Stack Software Engineer and AI Engineer with strong Development Knowledge and a high intend to enhance my knowledge and adopt the dynamic aspects of the IT Industry.

Now I am experienced in Full Stack Development and ML Engineer as well. I am comfortable on both sides. I am working remotely with US clients since 4+ years. Hope you will love working with me when we get started.
