What I'm looking for

I’m looking for a role where I can lead technical decisions for high-availability systems, design scalable API architectures, and partner with stakeholders. I want to ship reliable features through automation, strong code quality, and continuous improvement.

I’m a Systems Engineer with over 8 years of experience in backend development and technical team leadership, focused on high-availability systems for the healthcare sector. I’m driven by code quality, automation, and delivery of robust solutions that create real business impact.

I specialize in API-based architecture design, relational database modeling, and Linux environment administration. Across my roles, I’ve designed REST integrations between platforms and external services—often in mission-critical environments—while ensuring evolutionary maintenance of business-critical applications.

As a development lead, I coordinate planning, code review, and feature delivery, and I make architectural decisions for scalability and performance. I also lead database optimization work in MySQL and PostgreSQL, and I improve deployment processes and production stability through continuous deployment practices in Linux environments.

My practical stack includes Laravel/PHP and Django/Python, MySQL and PostgreSQL, Git, and Linux backend deployments. I’ve also worked with healthcare integration standards like DICOM, and I stay close to clients and stakeholders to translate requirements into scalable technical solutions.
