Profile Description

My expertise spans Django, FastAPI, NestJS, Express, React, and Next.js, with deep experience designing clean REST and GraphQL APIs, WebSocket pipelines, and message-driven systems using RabbitMQ and Kafka. I have built trading engines, fraud detection systems, AI-powered platforms, GPU-accelerated ML pipelines (PyTorch, CUDA, YOLO), and cloud-native services deployed across AWS, GCP, and Azure.

I’m highly experienced in Docker, Kubernetes, Terraform, CI/CD automation, performance optimization, and observability tooling (New Relic, Datadog). I care deeply about system reliability, scalability, security (OAuth2, JWT, OWASP), and clean architecture.

Beyond hands-on engineering, I’ve led microservices transformations, mentored teams, introduced DevOps culture, and driven technical strategy that improved deployment speed, system stability, and development velocity.
