Backend engineer specializing in event-driven distributed systems, high-concurrency APIs, and production data pipelines. Focused on database performance optimization, resilient worker topologies, and measurable business impact.

Standard event-driven microservices architecture I design and implement for high-load systems (Go/NestJS, PostgreSQL, Redis, BullMQ/RabbitMQ).

• Voice-Driven Engineering Agent (jarvis-dev-agent): Built a terminal-native AI agent that routes multilingual voice commands (RU/KZ/EN/KO) through a Whisper STT pipeline into real workflows: pre-flight diff review with PR generation, GitHub Actions failure triage, git pickaxe archaeology and autonomous tasks in isolated git worktrees, backed by a Gemini → Groq → Ollama failover chain.

• Distributed Media Generation Pipeline (ai-video-generator-saas): Architected an asynchronous video composition engine using NestJS, BullMQ, and FFmpeg. Quarantined compute-heavy AI rendering workflows into isolated worker queues, maintaining sub-50ms API response latencies while streaming bidirectional progress updates over WebSockets.

• Database Optimization & Inventory State Machines (B2B SaaS WMS): Engineered atomic FIFO/FEFO inventory allocation logic in PostgreSQL. Optimized complex relational queries and implemented Redis pipelining for high-load transaction paths, reducing P95 API response times from 2.5s down to 0.5s (80% latency reduction).

• Edge-Native Serverless Architecture (edge-serverless-crm): Engineered an edge-native CRM portal deployed across Cloudflare Workers and Cloudflare D1 distributed SQL storage, leveraging Web Crypto JWT authentication for sub-10ms global edge execution.

• Microservices Task Orchestration (distributed-kanban-microservices): Implemented a cloud-native Kanban platform enforcing the Database-per-Service pattern across decoupled PostgreSQL instances, orchestrated via Kong API Gateway (centralized JWT validation, rate limiting) with Celery & Redis asynchronous workers.

• Real-Time Fleet Routing Engine (smart-logistics-engine): Developed a containerized routing backend composing OpenStreetMap road networks (OSRM), vehicle routing problem solvers (VROOM), and ML-based delay estimation with live WebSocket dispatch telemetry.

• Threat Intelligence & LLM Security (phishguard-threat-intelligence): Built a real-time anti-phishing engine combining lexical parsing, WHOIS/SSL telemetry, and multi-LLM security triage streaming live detections via Server-Sent Events (SSE).

• AI Tooling & Codebase Intelligence (zod-mcp-server): Created an extensible Model Context Protocol (MCP) server providing AST-based code transforms, hybrid semantic vector search, and persistent agent memory.
