What I'm looking for

I’m looking for a team that values user-centric design and reliability, where I can lead full-stack and serverless architecture work, improve CI/CD and automation, and build high-impact products in modern AI-driven, data-intensive systems.

I’m a Senior Software Engineer with 10+ years of experience designing and delivering full stack applications, building scalable cloud systems, and driving product development in fast-paced environments. At HomeToGo, I led development of customer-facing platforms supporting over 50,000 active users, architecting serverless solutions with AWS Lambda, API Gateway, and DynamoDB to improve scalability and reduce infrastructure maintenance overhead.

I focus on user-centric design, system reliability, and high-impact delivery—whether I’m integrating billing and payment workflows with third-party providers, building internal tools and dashboards to streamline operations, or improving CI/CD pipelines and automated testing to reduce deployment time. I also mentor junior engineers and help raise engineering standards through code reviews and maintainable, well-documented codebases.
