What I'm looking for

I seek roles where I can lead development of mobile and backend systems, improve operational efficiency, and apply security expertise in collaborative, agile teams.

I am a senior software engineer and ethical hacker with over ten years building mobile and backend systems across e-commerce, logistics, and banking domains.

I design, develop and deploy native mobile applications and server-side solutions, and have led teams using agile practices to deliver production-grade software with very low bug rates.

I have broad technical experience across .NET, Java, Python, C#, Swift, Flutter, SSIS, SQL/NoSQL databases, cloud services (Google/Firebase, AWS, Azure) and penetration-testing skills from certified ethical hacking training.

I founded Emagii Tech and shipped multiple web and mobile products (contact-tracing, civic engagement, marketing broadcast apps) and supported enterprise integrations and Level 2 production support for large banking clients.
