What I'm looking for

I want to build user-centric, scalable web applications end to end—leading architecture, optimizing performance, and shipping reliable releases in Agile teams using AWS cloud and real-time capabilities.

I’m a Senior Software Engineer with 8+ years of experience designing and building scalable web applications using the MERN stack (MongoDB, Express.js, React.js, Node.js). I optimize backend performance, craft modern responsive interfaces, and drive technical initiatives in Agile environments.

At Walmart, I led the design and development of scalable SaaS platforms using React.js, Node.js, and Python for enterprise clients. I architected microservices-based systems deployed on Kubernetes, built RESTful APIs for integrations, and improved performance through MongoDB indexing, query tuning, and Python-based ETL processes.

I’m also proud of building secure, production-ready capabilities—implementing authentication/authorization with OAuth 2.0 and JWT, and automating CI/CD pipelines with Jenkins to reduce deployment time and improve release reliability. I’ve used AWS services like EC2, S3, Lambda, and CloudWatch, and applied infrastructure as code with AWS CloudFormation and Python (Boto3).

Earlier, at ELEKS and SoluLab, I delivered impactful products like a HIPAA-compliant healthcare platform and a high-performance trading platform with real-time data visualization. I collaborate cross-functionally to deliver user-centric solutions, consistently using tools like Jest and pytest for reliable testing.
