Bohdan D.

With 4+ years of commercial experience, I work across both frontend and backend, using TypeScript as my core language. My stack includes React, Next.js, Redux Toolkit, Tailwind CSS, Node.js, NestJS, Express, PostgreSQL, MongoDB, Prisma, and Mongoose. I’ve contributed to CRM systems, e-commerce platforms, and educational products, building features from scratch, improving existing architecture, and solving production-level challenges. I focus on writing clean, structured code and delivering solutions that are easy to scale, maintain, and extend. I also actively use AI tools such as Cursor and Claude to improve development speed and code quality. I treat AI as an assistant rather than a replacement - I design architecture and core solutions myself, then use AI to accelerate implementation. All generated code is carefully reviewed and refined to ensure it meets production standards and remains maintainable long-term. Selected experience: - led and contributed to full-stack development of CRM systems, e-commerce platforms, and educational products - refactored an existing codebase, reducing its size by ~40% and significantly improving maintainability - designed and delivered end-to-end features, including payments, subscriptions, and booking flows - built AI-powered features for content generation and workflow automation - improved system performance and stability by resolving critical production issues - implemented matching logic based on user preferences, availability, and goals - enhanced user experience with skeleton loading and optimistic UI updates - introduced unit testing (Vitest), reducing post-deployment issues I’m comfortable working independently or as part of a team, and I focus on clear communication, predictable development, and consistent delivery.
