What I'm looking for

I’m looking for a Senior Ruby on Rails / Full-Stack Rails role where I can architect scalable SaaS backends, build REST APIs, optimize database performance, and run CI/CD on AWS in an Agile team. I’m available immediately.

I’m a results-driven Senior Ruby on Rails Developer with 7+ years of experience building and scaling SaaS applications, enterprise web solutions, and REST APIs. I focus on reliable backend architecture, performance tuning, and clean, testable delivery.

Across healthcare and customer support domains, I’ve delivered high-throughput systems using Ruby on Rails, PostgreSQL, Redis, and Sidekiq. I’ve designed and maintained scalable API endpoints with JWT-based authentication and ensured strict SLA compliance for multi-channel customer communications.

I’m especially strong in identifying and resolving performance bottlenecks, including N+1 query issues in critical ActiveRecord models. I also build quality through RSpec/MiniTest, Postman-based API validation, TDD practices, and consistent code reviews.

My workflow is CI/CD-forward: I’ve managed Jenkins and GitLab pipelines for AWS deployments with zero-downtime releases. I’m currently open to Senior Ruby on Rails / Full-Stack Rails roles where I can keep delivering dependable features in fast-paced Agile environments.
