I build scalable full stack web applications, APIs, and integrations that improve performance and reliability.

I've built and maintained scalable web applications at KMS Technology, improving frontend performance by up to 35% and API response times by up to 30% through code and query optimization. I work across React, Next.js, Node.js, Python, Docker, and AWS services to deliver reliable product features and internal tools.

Across Azul Arc, ThoughtWorks, and Cosairus, I've developed customer-facing platforms, enterprise systems, APIs, integrations, and data-driven workflows. I bring hands-on experience with React, Angular, Vue.js, PostgreSQL, MySQL, MongoDB, REST APIs, GraphQL, technical design, and production support.
