About
I’m a senior Ruby on Rails engineer with 12.5+ years of experience building and modernizing SaaS platforms, especially for healthcare, logistics, food technology, and enterprise integrations. I focus on Rails architecture, microservices, REST APIs, and performance optimization—often taking legacy systems and evolving them toward scalable, maintainable solutions.
I also bring strong database engineering experience with PostgreSQL workloads supporting 50M+ records, plus cloud deployment experience on AWS and production-grade CI/CD. On top of that, I apply AI-assisted development workflows and an AI Development Lifecycle approach to improve delivery speed, code quality, testing, and operational monitoring.

Work experience
Led development of scalable Rails applications across healthcare and operational technology platforms. Modernized legacy Rails applications using updated Rails architecture and engineering practices, designed REST APIs and microservices-based integrations, and improved system performance through indexing, query optimization, caching, and background job improvements. Optimized PostgreSQL systems handling 50M+ records and migrated background processing workflows to Rails Solid Queue. Managed AWS/Heroku deployments and production infrastructure. Implemented AI-assisted development workflows and applied an AI Development Lifecycle (AIDLC) across requirement analysis, design, development, testing, review, deployment, and monitoring.
Developed and maintained Ruby on Rails applications across multiple domains. Built RESTful APIs, full-stack features, and third-party integrations, supporting enterprise needs. Worked with front-end technologies (React.js and Vue.js) alongside PostgreSQL/MySQL and cloud/container workflows using AWS and Docker, delivering improvements to scalable application architecture and performance within Agile teams.
