CV
I work as a project coordinator and team lead in a small but fully self-sufficient development team. My job is to help clients clearly define their project goals, choose the right technical approach, and ensure smooth communication and delivery at every stage. After clarifying your objectives, I translate them into a precise technical brief for my engineering team — and they immediately start working on the solution. Our core team includes: • Project coordinator & team lead • Frontend developer — React / Next.js / React Native • Backend developer — Node.js / NestJS / Express With this lineup, we cover the entire development process end-to-end. Our team specializes in: • Web development (React, Next.js, TypeScript) • Mobile applications (React Native for iOS & Android) • Backend/API development (Node.js, NestJS, Express) • Databases (PostgreSQL, MongoDB, Redis) • Authentication, notifications, payment systems, and third-party integrations • Deployment, scaling, and ongoing support We handle complete development cycles — from planning and architecture to coding, testing, deployment, and long-term maintenance. We can build full web or mobile applications from scratch or assist with ongoing development, refactoring, bug fixing, feature expansion, or performance optimization. If you need a reliable, well-organized team that delivers high-quality work with clear communication — I’m here to help. Let’s talk about your project!
