Ruby On Rails Senior Developer

Experienced Ruby on Rails Developer with a Strong Product and Automation Focus
I am a seasoned Ruby on Rails developer, with a strong background in product development, automation, and scaling SaaS applications. My journey into tech started in 2017 after completing my studies in accounting and finance, followed by a successful transition into software development. Since then, I have worked on a diverse range of projects, from building scalable SaaS platforms to optimizing backend architectures for high-traffic applications.
My core expertise lies in Ruby on Rails, where I have led projects encompassing monolithic to microservices transitions, applying Clean Code principles, TDD (Test-Driven Development), and Agile methodologies. I have experience working with Hanami, a lightweight Ruby framework, which allows me to build maintainable and high-performance web applications. I prioritize scalability, performance, and maintainability, ensuring that every solution I develop aligns with the long-term vision of the business.
Key Technical Skills:

• Backend Development: Extensive experience in Ruby, Rails, and Hanami frameworks, focusing on building API-driven and event-based architectures.
• Database Optimization: Experience with PostgreSQL and MySQL, ensuring efficient indexing, query optimization, and partitioning to handle large datasets.
• Cloud & DevOps: Hands-on experience with AWS, Heroku, and containerization using Docker. I have implemented CI/CD pipelines to streamline deployments and enhance development workflows.
• Automation & Integration: Proficient in integrating external APIs, including Stripe, Sendcloud, and EasyPost, automating operational processes and optimizing logistics workflows.
• Performance Optimization: Implementing caching strategies (Redis, Memcached), background job processing (Sidekiq), and APM monitoring (New Relic) to enhance application speed and efficiency.
• Microservices Architecture: Led the migration of large applications from monolithic Rails apps to microservices using technologies like Ruby on Rails, Java Spring Boot, and Node.js.

Professional Experience:
I co-founded Cineplanner, a SaaS platform aimed at helping independent cinemas manage employee scheduling effectively. Through this project, I:

• Designed and implemented a predictive scheduling feature, leveraging historical data to automate work assignments.
• Led the pricing strategy and market expansion efforts, offering a tailored solution for small and large cinema operators.
• Successfully managed the technical infrastructure, ensuring the platform remained reliable as it scaled to hundreds of users.

In my freelance work, I have collaborated with companies like ThePackengers, where I built backend solutions for logistics, including offline functionality for web applications used in the field. My work involved integrating APIs, designing fault-tolerant workflows, and ensuring smooth operations even in challenging network environments.
Soft Skills and Work Ethic:
I thrive in remote environments and excel in communication, organization, and problem-solving. Having worked with cross-functional teams, I understand the importance of collaboration, transparency, and delivering value-driven features. I am passionate about continuous learning and always seek to stay ahead of the curve in terms of technology and best practices.
