Software Engineer
Nikita Belousov
Software engineer: I design, build and ship web applications, AI agents and integrations — from architecture to production.
I work as a solo engineer with founders launching a new product. I take systems from a rough idea to a working production deployment: architecture, development, tests, monitoring — and I stay around after the launch. I build new products from scratch and keep them running for years; I do not take over or patch up other people's existing projects.

Case studies
Investorum — AI-run investment magazine
investorum.ru: a weekly Russian-language magazine written end-to-end by an AI pipeline of 6 specialized agents, plus a model portfolio managed by the same system on a real brokerage account. 180 unit tests, contract orchestration, full call auditing. Built, deployed and operated by me alone.
investorum.ruSunny Piter — autonomous Telegram channel
A Telegram channel about St. Petersburg that runs itself: a pipeline of AI agents finds events, writes posts, fact-checks every claim and publishes 5 times a day — no human in the loop.
