I am a results-driven Senior Software Engineer with extensive experience in designing scalable backend systems, optimizing database performance, and implementing secure authentication solutions using Ruby on Rails, Node.js, and PostgreSQL. My proven ability to enhance system efficiency and automate deployments has been instrumental in leading cross-functional initiatives that improve application performance and security in enterprise payroll and cloud-based solutions.

At ADP, I architected payroll processing APIs in Ruby on Rails, optimizing query execution paths to handle increased transaction volumes without sacrificing performance. I also designed database schemas in PostgreSQL, improving search accuracy and reducing indexing overhead for tax and compliance lookups. My role involved developing a role-based access control system with OAuth, which significantly improved data security for multi-tenant payroll solutions.

Previously, at Dataplor, I developed and maintained scalable web applications, enhancing data processing efficiency and supporting millions of location-based records. I led the migration from a monolithic Rails application to a service-oriented architecture, leveraging Docker, AWS ECS, and Kubernetes to improve deployment speed and scalability. My experience at Microsoft further solidified my backend development skills, where I engineered backend services in Node.js and TypeScript, powering authentication and API gateway services for enterprise clients.
