Description

Need to launch a high-performance mobile app, scale your web frontend, or build a secure, enterprise-grade backend? I am a Full-Stack Software Engineer specialized in delivering clean, maintainable, and production-ready applications from architectural design to deployment.

By bridging the gap between mobile interfaces, web platforms, and robust backends, I help startups and mid-sized companies accelerate their product delivery without sacrificing code quality.

What I Bring to Your Project:

Mobile Development (Flutter): Production-ready mobile apps built under strict Clean Architecture. Expert in state management (BLoC/Cubit), local data synchronization (offline-first with SQLite), geospatial/mapping integrations, and multi-environment pipeline setups (Flavors).
Modern Web Frontend (Angular & React 19): Scalable web applications and enterprise management panels. Highly skilled in modular architectures (Nx Monorepos), reactive programming (RxJS, Signals), and global state management (NgRx, Zustand).
Robust Backend (Spring Boot/Java): Secure and reliable RESTful APIs, clean business logic decoupled from frameworks, and optimized database persistence (JPA/Hibernate, MySQL).

Why Work With Me?

Architecture-First Mindset: I don't just write code; I ensure your system is modular, easily maintainable, and ready to scale as your business grows.
Agile & Autonomous: Fully integrated into Agile/Scrum workflows. I thrive in collaborative environments and take full ownership of the features I deliver.
Open Source Contributor: Active in the developer community with published packages on Pub.dev.
