I build web applications end to end: React / Next.js interfaces, Node.js APIs, MongoDB data models, and serverless deployments on AWS. I like turning messy real-world workflows into simple, well-documented products.
馃煝 Open to remote full-stack, frontend (React / Next.js), and Node.js backend roles, as well as freelance projects.

馃憠 More case studies (including private commercial projects): portfolio
- End-to-end ownership: from product workflow and UI to API contracts, data models, and deployment.
- Third-party integrations: Google Play Developer API, App Store Connect, OpenAI, Telegram, and AWS.
- Clear documentation: setup, constraints, and trade-offs written down so another developer can pick up the project.
- Client communication: experience working directly with clients and teaching and mentoring developers at GoIT.
