About

Professional summary

I am a Senior Full Stack Engineer with more than 18 years of software engineering experience and over 10 years building modern cloud-native SaaS platforms and high-performance web applications.

I work across frontend and backend technologies, with deep experience in Next.js, React, Angular, TypeScript, FastAPI, .NET Core, Node.js, and C#. I take ownership of system architecture from solution design through production deployment.

I have built multi-tenant SaaS products, modernized legacy enterprise applications, and delivered secure REST APIs and responsive user interfaces. My work includes RBAC, secure API design, relational data modeling, microservices, and distributed systems.

I have experience deploying and maintaining applications on Azure using CI/CD practices, Azure DevOps, GitHub, and Bitbucket. I focus on performance optimization, deployment reliability, maintainability, and production issue resolution.

I have worked in HRMS, public safety learning management, manufacturing, e-commerce, marine IoT, and fintech investment platforms. I also mentor engineers on code quality, architecture, and delivery practices.

I actively use AI-augmented development tools such as Claude, GitHub Copilot, and ChatGPT to improve code quality, accelerate debugging, and reduce delivery timelines.
