Full-stack developer with 10+ years in IT. I build and fix web, desktop and mobile apps, APIs and Chrome extensions in TypeScript, JavaScript and Rust. That includes Lovable and Bolt apps that aren't ready for real users yet. I also add AI features to existing products: LLM integrations, document search and chatbots.

Stack:
- Languages: TypeScript, JavaScript, Rust, SQL, HTML, CSS/SCSS
- Front end: React, Next.js, responsive interfaces that I design myself and build without templates
- Back end: Node.js (Express, NestJS), Deno, Rust (axum), REST and gRPC APIs, Kafka
- Databases: PostgreSQL with row-level security, MySQL, MariaDB, MongoDB, Redis, Supabase
- AI: LLM integrations that check the model's output before saving it, vector search on pgvector, RAG chatbots that answer from your files
- Platforms: WordPress and WooCommerce, multilingual sites with WPML, Chrome extensions (Manifest V3), desktop apps with Tauri, mobile apps in React Native
- DevOps: Docker, Kubernetes, Helm, werf, CI/CD on GitHub Actions and GitLab CI
- Integrations and automation: payment providers, third-party APIs, scheduled jobs with an alert if one stops running

What I take on:
- Apps built with Lovable, Bolt, Cursor or v0 that work for the founder but aren't ready for real users: broken sign-in, failing payments, missing access rules, code nobody wants to touch
- New web apps from the database to the interface, plus landing pages and multilingual sites
- AI features in an existing product: LLM summaries and scoring, search over your documents, chatbots that cite their source
- Bug fixes and performance work on slow pages, API endpoints and database queries
- Backends, APIs and command-line tools in Node.js or Rust
- Desktop, mobile and browser-extension projects

Experience:
- Supabase in production: scheduled TypeScript functions, LLM steps whose output is checked before it is saved, pgvector search, an alert whenever a scheduled job stops running, and CI on every push to main
- Access control inside PostgreSQL: row-level security policies and a separate role for each subscription tier, so users see only what their plan allows
- A legacy PHP backend rewritten in Node.js/TypeScript without breaking its API; median response time on the main endpoints fell roughly 3×
- A jQuery front end moved to React page by page while the product stayed live
- Rust backends: axum microservices on PostgreSQL and Redis that talk to each other through Kafka and gRPC, with a REST API for the front end
- Open source: reqwest-rotate, my Rust crate for proxy rotation, per-host rate limits and retries in the reqwest HTTP client, published on the official Rust registry
- Live demos and client work are in my portfolio, and my public code is on the GitHub account linked to this profile.

How I work: async and in writing. I write the scope down before I start. Well-defined work gets a fixed price; open-ended work is billed hourly until the scope is clear. You get a short written update at the end of each working day, and no calls are needed. I work 10:00–20:00 Almaty time (UTC+5), which covers most of the European working day and the start of the US East Coast day.
