What I'm looking for

I’m looking for a role where I can build scalable, secure backend services on AWS, ship RESTful APIs with strong CI/CD and automated tests, and collaborate closely with engineering and product to improve performance, reliability, and customer outcomes.

I’m a Back End Engineer with “AWS, Python, PHP, C#, Javascript, Java experience,” and I enjoy building and maintaining APIs and web applications that optimize online presence and performance. I value teamwork, innovation, and customer satisfaction, and I strive to deliver high-quality solutions that meet or exceed expectations.

Currently, I work as a Back End Engineer at Flexkeeping by Mews, supporting hospitality SaaS products for hotel operations and guest engagement. I collaborate with the CTO and other developers to design and implement scalable and secure backend infrastructure using AWS Chalice, Python, and PostgreSQL, while writing automated tests and CI/CD pipelines on Git to ensure code quality and fast deployment.

Previously, I worked as a Back End Developer and Data Engineer at OpenTeams and Opensupermall, where I contributed to projects across Django, Node.js, MongoDB, and data/analytics tooling like Panda and Numpy, plus visualization with Bokeh. I helped improve system design, architecture, reporting, storage, and monitoring—driving increased efficiency, reduced latency, and improved user retention.

I also brought strong backend fundamentals to contract work such as Aardvark, where I supported system design and architecture alongside the CTO and improved release performance using Git-based CI/CD with automated tests. I’m passionate about learning new technologies and best practices, and I’m always eager to take on new challenges and solve problems.
