What I'm looking for

I’m looking for a role where I can build scalable, high-performance applications using React/Node and cloud (AWS/Azure), strengthen CI/CD and testing, and contribute secure, data-driven solutions in an Agile team.

I’m a Sr. Software Engineer with industry experience building scalable, high-performance applications across Front-End and Back-End services. I work across the project lifecycle, turning requirements into production-ready features with strong test coverage and continuous delivery practices.

In my recent role, I migrated and maintained a production graphing application by streamlining source code retrieval and execution, improving usability for stakeholders. I updated and tested complex SQL queries to extract targeted data from MongoDB and optimized front-end data accuracy and visibility by 20%, while also creating automated unit and integration testing to increase productive code merged by 22%.
