Hi, I'm

Ruslan

Full-Stack Developer

I build full-stack web applications end-to-end – from the database to the browser to the infrastructure they run on.

01About

Full-Stack Developer with 4+ years of experience building production web applications end-to-end – backend, frontend, and increasingly the infrastructure behind them.

Day to day I work across Node.js/Express and Python/FastAPI on the backend, React/Next.js on the frontend, PostgreSQL/MSSQL, Redis, Kafka and MinIO. I own my features from requirements to deployment.

One thing I'm proud of: our deployments used to be fully manual – Docker on a bare VPS, Nginx configured by hand. I taught myself Kubernetes (K3s), Helm and Argo CD, moved the team to automated, GitOps-style deployments, and I'm now building out full CI/CD on top of that.

I've also built systems for government clients, including a document-tracking archive with QR/barcode scanning and WASM-based electronic signature verification.

The DevOps side is what I'm most drawn to right now, and I keep pushing further into it – a fast learner who picks up new tools quickly and integrates smoothly into a team's existing workflow. I communicate clearly and work well with others, whether that's fellow developers, a PM, or a client.

Full-Stack Developer – KAI

Own full-stack delivery of internal and government-facing products end-to-end – from database and API design to frontend and deployment.
Designed and built an electronic document archive system with a self-service admin panel: staff configure their own building/floor/room/shelf structure and populate it themselves; the app also scans QR/barcode codes to track which document is where and who currently holds it (PostgreSQL + Express API).
Integrated WASM-based electronic digital signature (EDS) verification for a government-facing service.
Built an admin service (React + TypeScript, Express + TypeScript) with JWT authentication and Redis-backed sessions.
Identified that deployments were fully manual (Docker on a bare VPS, Nginx configured by hand) and led the shift to automation – learned and rolled out Kubernetes (K3s), Helm and Argo CD for GitOps-style deployments, now extending this into full CI/CD pipelines.
Provisioned and hardened VPS infrastructure; configured Traefik/Nginx reverse proxies, domains and SSL certificates.
Integrated a Telegram bot for automated service notifications.

April 2021 – January 2023Remote

Full-Stack Developer – IT-grant

Built and owned microservice REST APIs (Node.js/Express) that synced ~5,000 records nightly from an external government service and Google Sheets into PostgreSQL, exposing the data through a documented (Swagger) API.
Delivered a public-facing website (Next.js + Express + TypeScript) with a separate admin panel (Vite + React) and JWT-based authentication.
Built image processing and storage pipelines using PostgreSQL and MinIO.
Configured Google Search Console, page indexing and on-page SEO for the production site.

05Projects

Electronic Document Archive System

Web application for a government institution that tracks physical document locations via QR/barcode scanning, with a self-service admin panel for staff.

WASM Electronic Digital Signature Integration

Integrated WebAssembly-based electronic digital signature (EDS) verification into a government-facing web service.

Admin Panel with JWT Authentication

Full admin service built with React + TypeScript on the frontend and Express + TypeScript on the backend, featuring JWT authentication and Redis-backed sessions.

Manual-to-Automated Deployment Migration

Led the transition from fully manual deployments (Docker on a bare VPS, hand-configured Nginx) to automated, GitOps-style deployments using Kubernetes (K3s), Helm and Argo CD.
