About

Professional summary

I am a software engineer with more than 10 years of experience building and improving full-stack web applications. My core expertise is in Python and JavaScript, with a focus on reliable backend services, responsive user interfaces, and practical business solutions.

I architect and develop backend systems using Python and Flask, including APIs, data validation, business logic, asynchronous processing, and secure data handling. I also build frontend experiences with JavaScript, Vue.js, HTML, and CSS to improve usability and application performance.

I have experience designing real-time data interfaces, data models, relational and NoSQL database solutions, and cloud-based systems on Google Cloud Platform. I prioritize observability, scalability, deployment quality, monitoring, and production reliability.

My work includes supporting regulatory and security requirements, including HIPAA and CCPA compliance. I apply data privacy, access-control, auditability, and security practices to protect sensitive information and maintain trustworthy systems.

I have led technical improvements, mentored junior developers, collaborated with product managers and designers, and supported incident response. I am especially interested in using technology, AI-assisted development, and automation to improve education technology and family engagement.

I also bring IT modernization and quality assurance experience, including system migrations, SQL Server upgrades, Windows Server administration, application testing, and user support. I value clear documentation, cross-functional communication, code reviews, and continuous improvement.
