Iskhak Ishmakhametov

About

Full-stack product engineer with a strong real-time systems focus: built and rolled out a WebSocket-based notifications system (with robust reconnect/resync and event ordering protections) that cut update latency to under 200ms. Also owned a workflow automation platform backend in FastAPI (JWT/RBAC, versioned APIs, standardized errors), designed the PostgreSQL schema for workflows/tasks/executions, and operated deployments on AWS ECS Fargate with blue-green CI/CD and performance stabilization via caching and autoscaling.

Key Strengths

• Shipped end-to-end real-time notifications system (WebSockets + React hook) reducing update latency to <200ms
• Designed resilient real-time client behavior (exponential backoff reconnects, session resync, dedupe/out-of-order handling via sequence IDs)
• Scaled event delivery by migrating from in-memory queue to Redis Pub/Sub
• Built production Python backend with FastAPI using JWT auth + RBAC, URL-based API versioning, and standardized error handling
• Strong testing discipline across stack (pytest unit/integration, load testing, Jest/React Testing Library with WebSocket mocking)
• Data modeling for workflow automation in PostgreSQL (FKs, composite indexes, monthly partitioning, denormalization driven by query patterns)
• AWS production operations with ECS Fargate/RDS/S3, GitHub Actions CI/CD, blue-green releases, and latency-based autoscaling/caching to handle traffic spikes
