Full-Stack Development with TypeScript & Modern Frameworks
Expertise in TypeScript, JavaScript, Vue.js, Nuxt, React, Next.js, Node.js, NestJS, and HTML/CSS. Delivery of complete full-stack products from UI to backend, including micro-frontend architectures and real-time data synchronization.
Agentic Engineering & AI Integration
Hands-on experience building and operating multi-tenant AI-agent platforms using Claude Code, Claude Agent SDK, MCP servers, OpenHands, LiteLLM, and RAG. Design of governed coding agents with quality gates, LLM cost control, and agent tool-call gating.
Cloud Infrastructure & DevOps
Proficiency in Kubernetes, Docker, Helm, GitHub Actions, AWS, and Redis. Architecture and solo-shipping of multi-tenant Kubernetes PaaS solutions with per-tenant isolation, CI/CD pipelines, and identity-proxy boundaries.
Software Architecture & Micro-Frontends
Design of scalable frontend and backend platforms using micro-frontend architecture, REST APIs, spec-driven development, and quality gates for AI-generated code.
Security & Authentication
Implementation of Keycloak, OAuth2/OIDC, and RBAC for secure, access-controlled multi-tenant environments with operator-defined checks and audit trails.
Database & Data Infrastructure
Experience with PostgreSQL including pgvector for vector search, Redis for caching, and Docker-based data layer management in production environments.
Testing & Quality Assurance
Application of Playwright E2E testing, spec-driven development, and automated quality gates. Established quality gates for a days-long agent-driven refactor, with zero regressions found.
Creative UI & Visualization
Use of Figma, Three.js, GSAP, D3.js, and Blender for creative UI design and high-performance real-time visualization systems handling tens of thousands of concurrently synchronized objects.

Project history
Built an alpha workspace where a person describes a Godot game in chat and an AI agent builds it. The platform runs scripted playtests, sends failed checks back to the agent, and delivers changes as pull requests to the owner's GitHub repository.
Published lf-godot-gd-utils, an open-source Godot 4 library of 82 documented GDScript modules covering networking, state replication, flow-field pathfinding, spatial indexing, loot and progression systems, and UI, with 3,000+ tests and CI on Linux, macOS, and Windows.
Shipped a production portfolio site for an artist (dzhumanoks.art): server-rendered Nuxt, 4 locales, per-work SEO/OG pages, Lighthouse-audited performance, and admin auth via the platform's shared Keycloak.
