I turn product ideas into reliable cross-platform apps - from crypto wallets and asset registries to media and university platforms.

• Build React Native / Expo apps that ship to both iOS and Android with one codebase.
• Design and implement Node.js / TypeScript backends and APIs that are simple to reason about and easy to maintain.
• Work end-to-end: requirements → architecture → implementation → testing → CI/CD → releases → monitoring.
• Focus on performance, crash-rate reduction, and developer experience so teams can move fast without breaking things.

• Integrated NEAR, Cosmos, Astar, Bitcoin, Polkadot native wallets and MetaMask-compatible EVM wallets into a single mobile wallet.
• Shipped Astar Portal support in ~2 weeks with 0 crashes at launch.
• Reduced app load time by ~30% through bundle optimization, lazy loading, and caching.
• Improved WalletConnect reliability and UX across Ethereum and Solana signing flows.
• Contributed across both React Native (mobile) and Node.js (backend) to move the product forward.

• Delivered a cross-platform asset-registry app in React Native, matching Figma designs with <2% visual diff across screens.
• Reached 99%+ crash-free sessions in beta by tightening error boundaries and adding monitoring.
• Established a maintainable codebase using React Native best practices and a clear separation-of-concerns architecture.
• Reduced defect risk by adopting TypeScript end-to-end, including strict typings for third-party libraries.
• Set up advanced project tooling (ESLint, Prettier, strict TypeScript configs) to keep the codebase predictable and consistent.

• Built a University mobile app as a Bachelor's thesis, translating the full website functionality into a mobile experience for students and staff.
• Shipped Jurnal FM - live radio streaming + a news section for real-time updates.
• Shipped Radio Ciufulici - a simple, intuitive, and reliable live radio streaming app.
• Standardized project setup with TypeScript, ESLint, Prettier, GitHub Actions to keep releases boring and safe.

Tooling and DevEx: TypeScript (strict), ESLint, Prettier, Jest, Docker, GitHub Actions, Sentry
Web3 and integrations: WalletConnect, multi-chain signing flows, crypto wallets
State and data: Zustand, React Query

• Own features end-to-end - from early product conversations to post-release metrics.
• Keep PRs small, readable, and focused, with tests where they matter most.
• Prefer clear, async-friendly communication and good documentation over meetings.
• Care about DX (developer experience): fast feedback loops, solid tooling, and clean architecture.
• Always leave the codebase slightly better than I found it.
