🟢 Open to new roles: remote or relocation

I'm a backend engineer from Uzbekistan with 2+ years of experience building SaaS platforms, payment systems and AI-powered applications, and running them in production.

I build multi-tenant software with Node.js, NestJS, Scala, PostgreSQL and Redis, plus modern LLM tools such as RAG and AI agents. I care about scalable architecture, performance, CI/CD automation and shipping software that is ready for real users.

Multi-tenant school management SaaS

• Moved the live backend from Scala to NestJS with zero downtime. About 98% of the app now runs on the new backend, and schools never noticed the switch.
• Built an AI assistant and document platform: it answers from uploaded PDF and Word files with sources, works in Telegram with voice and images, and keeps every school's data strictly separate.
• Built an analytics system with 350 metrics and early warnings for struggling students, and made the slowest report 25× faster.
• Ran a full security review and fixed every serious issue, including one that could have allowed a platform takeover.
• Set up zero-downtime releases (live in 2–3 minutes, one-command rollback) and SIP telephony with call recording and AI transcription.

Online exam-prep and testing platform for students and schools

• Built online card payments on my own with the Atmos payment provider: saving cards with SMS confirmation, payments, cancellations and refunds.
• Built automatic subscription renewal with retries and a grace period for failed payments.
• Secured payments: only the provider can reach the payment endpoints, and cards and passwords are stored encrypted.
• Made the public test catalogue faster with Redis caching and PostgreSQL indexes.

Exam-prep platform for driving schools

• Designed and built the whole product alone: student, teacher and admin portals plus a mobile app. Live since 2024.
• Built the exam simulator (1,300+ questions, timed tests, a "my mistakes" mode) and student readiness reports.
• Built the school's back office: groups, payments and debts, salaries, statistics and a lead pipeline.
• Set up zero-downtime releases with automatic rollback, a staging environment and nightly backups.

• HealthOS: a health platform (NestJS, Next.js, React Native) with live sensor readings, early warnings and an Android app that works offline.
• Brandlly: an AI branding tool for startups (Next.js, NestJS). Code: frontend · backend
• jarvis: clap twice or say a wake phrase and your laptop runs a command. Private, with no cloud (Python).
