About Me

I am a Senior Software Engineer with 18 years of experience designing, building, and scaling high-performance web applications across startups, enterprises, and remote-first global teams. My expertise spans backend systems, frontend architecture, cloud infrastructure, and DevOps, with deep hands-on experience in React, Vue, Angular, Node.js, Python, and distributed systems. I have a strong track record of modernizing legacy platforms, improving scalability and performance, mentoring engineers, and accelerating product delivery.

I am comfortable operating across the full software development lifecycle—from system design and implementation to CI/CD, production support, and stakeholder collaboration. I have designed and maintained user onboarding and workforce management platforms, developed core backend and frontend modules, and improved data scalability and query performance using cloud platforms like Google Cloud Platform.

My experience includes delivering mobile applications using React Native to improve accessibility and task completion efficiency. I have collaborated closely with product and operations stakeholders to translate complex operational requirements into reliable, maintainable software solutions. I have also built plugin publishing and management systems, knowledge-sharing platforms, and developer documentation sites to enhance developer experience and productivity.

I have led frontend modernization initiatives, migrating legacy interfaces to React, resulting in improved UI performance and higher customer satisfaction. I provide technical guidance and mentorship to junior developers while contributing hands-on to core platform development. Additionally, I have led the vision, architecture, and implementation of scalable full-stack systems using modern technologies such as React, Django, Docker, and cloud services.

I have contributed to backend and DevOps for ML-driven infrastructure platforms, healthcare automation systems, fintech and insurance automation, and large-scale eCommerce analytics solutions. I am experienced in designing autoscaling architectures, CI/CD pipelines, message-driven systems, and cloud-native deployments using Docker, Kubernetes, AWS, and GCP. I am comfortable balancing hands-on engineering and technical leadership with a strong focus on performance, maintainability, and long-term system health.
