Umidjon Tojiboyev
Software Engineer
I started coding formally at around 15. Today I work across the stack — Next.js and React on the front, Node.js/TypeScript and Spring Boot on the back, SAP Business One and HANA SQL on the enterprise side. My debut Habr article on PostgreSQL design hit the top-5 of the day across the largest CIS developer community, and I was invited to join the Habr content studio. I participated in the International AI Forum in Tashkent at the launch of the "Five Million Uzbek AI Prompters" initiative, and I build AI automation pipelines with n8n and the Claude API.
