What I'm looking for

I am looking for opportunities that foster collaboration, innovation, and career growth.

As a Senior Backend Engineer with over 8 years of experience, I specialize in designing, building, and maintaining scalable server-side applications and APIs. My proficiency in programming languages such as Python, Java, C#, PHP, and Node.js allows me to deliver high-quality, secure backend solutions. I am passionate about solving complex engineering problems and continuously optimizing performance in Agile environments.

Currently, I work at IBM, where I have developed and maintained microservices for enterprise cloud-based platforms. My efforts in collaborating with frontend developers have improved client response times by 30%. I also led the migration of legacy PHP services to a modern Java backend architecture on AWS, implementing CI/CD pipelines that reduced deployment time by 40%. My previous roles at Cognizant Technology Solutions and Infosys have further honed my skills in backend development and cross-functional collaboration.
