What I'm looking for

I’m seeking a role building cross-platform mobile and web applications in a collaborative, growth-oriented team where I can apply Flutter and full-stack skills and integrate AI-driven features.

I am a software engineer with 3+ years of experience in mobile and web development, focused on building fast, scalable, and user-focused applications using Flutter, JavaScript, Node.js, and Spring Boot.

I have migrated over 20 applications to Flutter to improve cross-platform compatibility and performance, and engineered Litteraworks as a collaborative journalism tool delivering real-time transcriptions and faster workflows.

As a collaborative team member at Appworks, I contributed to product roadmap decisions, integrated AI tools to enhance user experience, and demonstrated strong problem-solving by troubleshooting complex technical issues.

My background includes roles in IT administration, freelance software development, and a junior project manager/software tester internship; I hold a Bachelor's in Software Engineering and a Master's in Contemporary Information Technologies.
