What I'm looking for

I'm looking to build production-ready software where I can apply full-stack, healthtech, interactive systems, and AI experience to solve complex client and business needs.

I've built production-ready software for Geovictoria, SpecTainment, and IST, spanning scalable backend systems, interactive applications, and virtual-reality rehabilitation software. At Geovictoria, I refactored 20+ legacy .NET modules, reduced code complexity by 30%, and improved Power BI report generation speed by 25%.

As a freelance full-stack developer, I've delivered 7+ responsive web applications for SMB clients using Flutter, Python, cl

oud functionality, REST APIs, and SQL Server. I improved user retention by 40%, reduced query latency by 35%, and introduced Git-based QA practices that cut post-launch bugs by 30%.

I'm especially drawn to healthtech and interactive system design, including Oculus rehabilitation software and my current AI-powered fitness app for sedentary women. I bring direct client coordination, technical solution design, and practical experience turning complex requirements into reliable applications.
