What I'm looking for

I seek roles where I can build and maintain production-grade web, mobile, and backend systems, work with modern stacks (TypeScript, Rust, Flutter), and contribute to scalable, test-driven architectures in collaborative teams.

I am a Full Stack Software Engineer with three years of hands-on experience building web, mobile, and backend systems using TypeScript, React, Next.js, Flutter, and Rust. I focus on delivering production-grade applications with strong attention to backend architecture, system integration, and reliability.

At Oriontec I built a real-time call identification service in Rust that reduced technician response time by ~30% and fully automated manual call registration, while modernizing legacy workflows into scalable backends. I also led end-to-end web and mobile projects, applying Clean Architecture, SOLID, and TDD to improve maintainability and onboarding.

I have delivered performance optimizations across frontend and backend stacks—improving page performance and SEO, cutting SQL query times by 83%, and contributing to mobile apps with 10,000+ users. I prioritize pragmatic, testable solutions and clear engineering standards that enable teams to ship dependable software.
