System Architect

Designing complex frontend systems with high interactivity, real-time synchronization, and AI component integration

Damir Karimov

System Architect (Frontend / FSD / Real-time / AI Systems)

Specializes in designing complex frontend systems with high interactivity, real-time synchronization, and AI component integration. The main focus is building architectures that remain manageable as business logic, user roles, and external integrations scale. Experienced in developing multi-tier platforms with financial operations, document workflows, access roles, and complex user scenarios. Works closely across frontend, backend, and automation services to ensure system consistency at the semantic contract and state level.
FSD Architecture
React / Next.js
Real-time Systems (WebSockets)
AI & LLM Integrations

Key Competencies

Architecture design based on Feature-Sliced Design (layer and module isolation)

Building complex UI systems with multiple roles and scenarios

Implementing real-time logic (WebSockets, event synchronization)

Data layer design (RTK Query, caching, revalidation)

External systems integration (EDO, Digital Signatures, 3rd party APIs)

Development of internal automation services (Node.js, Python)

Building AI integrations (LLM, RAG, voice interfaces)

Architectural Approach

System decomposition into independent areas of responsibility
Strict module boundary enforcement (FSD)
Contract-based interaction between layers
Event-driven model for real-time updates
State and side-effects minimization
Managing complexity through isolation and predictability

Practical Experience

Financial systems implementation (balances, transactions, invoices, withdrawals)

Real-time systems engineering with status, chat, and notification synchronization

Complex catalogs development with filtration, parametrics, and dynamic querying

Entity lifecycle management (orders, statuses, deadlines, constraints)

Electronic document management and digital signature integration (including desktop-bridge automation)

Automation pipeline construction (screenshots, reports, PDF/Excel generation)

Headless browser interactions (Playwright) and bypassing external platform restrictions

Internal real-time messenger development with full state sync

Administrative management systems with moderation, accounting, and multi-tenancy

AI & Intelligent Systems

Voice AI-agent implementation with real-time interface control
Multi-service orchestration (voice, RAG FAQ, retrieval search)
STT / TTS / LLM integration into unified pipelines
RAG systems engineering (vector search, LangChain, ChromaDB, Qdrant)
Hybrid search: SQL + vector semantics + reranking
Voice-controlled UI with action confirmation (ACK model)
State synchronization between AI agent and interface
