What I'm looking for

I want to build reliable, high-performance backend systems and secure APIs, shipping production-ready cross-platform mobile experiences. I’m excited to work in teams that value clean architecture, automated testing, and thoughtful security.

I’m a backend-focused software engineer specializing in API design and cross-platform mobile development, with a strong emphasis on secure coding, performance optimization, and scalable architecture. I also evaluate AI-generated software engineering outputs for correctness, security, scalability, and maintainability—so the solutions hold up in real systems.

At Anozen, I’ve led the design and development of a healthcare-focused mobile and backend platform for production users. I build scalable RESTful APIs with Python, PostgreSQL, and Firebase, develop cross-platform apps with Flutter, optimize database queries and performance, and implement automated testing and production issue resolution—while aligning with secure development practices and healthcare data privacy requirements.

Beyond product engineering, I do responsible security research on web and mobile applications through coordinated vulnerability disclosure, identifying authentication and access control weaknesses and recommending remediation. I’ve also delivered freelance backend systems, mobile apps, and REST APIs for international clients, and I strengthen my fundamentals through hands-on training in Linux, systems security, and networked application behavior.
