Backend and mobile developer specializing in cloud services, APIs, and Flutter.
What I'm looking for
I am a backend and mobile developer with hands-on experience building cloud services, RESTful APIs, and cross-platform mobile apps using Node.js, TypeScript, NestJS, and Flutter. I led development of TafiCloud — a cloud subscription, file storage, and analytics platform — and contributed to production fintech and consumer mobile apps, integrating databases and services to improve scalability and maintainability.
I prioritize reliable, maintainable systems and clear developer experience, having authored an SDK for client file operations and implemented Redis, PostgreSQL, and Sequelize integrations to enhance performance. I enjoy solving complex problems, building admin tools and dashboards, and shipping end-to-end features from backend to mobile.
