I build web applications end-to-end — from React interfaces to NestJS microservices talking to each other over gRPC. I like taking a project from "here's what we need" all the way to something running in production and used by real people.
- Frontend Developer @ Chistaya Energiya (2025–2026) — built and refactored the BimAR app in React/TypeScript, migrated the build pipeline from Webpack to Vite, introduced ESLint/Prettier for the team
- Full-Stack Developer @ Gratio & Batonis (2022–2024) — built Specifikator, a project-estimation tool (React · Express · PostgreSQL · Keycloak) used to plan work, staffing, and cost for client projects; shipped a framework-agnostic UI kit with native Web Components; delivered React apps for multiple clients
- Freelance Full-Stack Developer (2020–2022) — built web apps for private clients with React, Node.js/Express, and relational databases
Today I maintain a production system of 13 NestJS microservices (PostgreSQL, RabbitMQ, Redis, gRPC) as part of my own SaaS projects.
- speka.click — a PaaS for writing and maintaining software specifications for teams
- KnowledgeGraph — a SaaS for personal knowledge management, with API and MCP access
- Voyage — a travel agency platform, modernized with AI-powered features
- BimAR — frontend app I develop and maintain, including a 3D module built with Three.js; designed the Module Federation architecture on Vite

AI & LLM Tooling
I use these to build agentic chains — multi-step, tool-using LLM workflows — on top of my own projects.
Deepening TypeScript, exploring Deno, and going further into C#/.NET and Docker internals (image builds, mounts, multi-stage deployments) — building toward stronger backend and infra skills.
