I’m an experienced system analyst and software professional with 15+ years across the full SDLC—requirements, design, development, documentation, testing, deployment, version control, and production support. My work spans civil, commercial, and MNC environments, and I’ve built and maintained web applications and services using JavaScript/Java, RESTful APIs, Angular/React, and cloud platforms like AWS. I enjoy turning complex business and data needs into reliable, maintainable systems—whether that means refactoring for microservices, troubleshooting stored procedures and data transformations on SQL platforms, or enhancing internal tools used by researchers and operations teams. I also bring strong collaboration skills from agile delivery, coordinating releases, guiding developers, and producing clear technical documentation from discovery through UAT and release handover.…I’m an experienced system analyst and software professional with 15+ years across the full SDLC—requirements, design, development, documentation, testing, deployment, version control, and production support.
