DevOps Engineering & Infrastructure (Q1-Q2 2025)

• Advanced Kubernetes patterns and operators
• CI/CD pipeline optimization and GitOps workflows
• Infrastructure as Code (Terraform, Helm)
• Cloud-native observability and monitoring
• Container orchestration and service mesh architectures

4+ Years Backend Engineering Experience building high-scale production systems across ride-hailing, telecommunications infrastructure, and travel industries.

Key Achievements:

• Architected microservices infrastructure for real-time geolocation and ride-matching platform serving thousands of concurrent users
• Built national-scale DCIM monitoring system tracking data center infrastructure across Iran's telecommunications network
• Designed and implemented CI/CD pipelines eliminating deployment bottlenecks for 29-developer engineering teams
• Developed comprehensive observability solutions using Prometheus, Grafana, Loki, and Tempo for critical infrastructure
• Optimized database performance and query patterns for high-traffic applications handling millions of requests
• Mentored engineering teams on architectural patterns, code quality, and DevOps best practices

Primary Focus Project - Q1 2025

Enterprise-grade AI Gateway demonstrating advanced software architecture patterns for multi-provider LLM routing and management. A showcase of clean architecture principles applied to modern AI infrastructure.

Architecture Highlights:

• Pure DDD Implementation with bounded contexts: Completion Context, Billing Context, Workflow Context, Platform Context
• Hexagonal Architecture with strict port/adapter separation ensuring framework independence
• Shared Kernel for cross-cutting domain concepts and events
• Strategic Design Patterns: Factory, Strategy, Decorator for routing and caching logic
• Value Objects for type safety: Cost, ModelName, Prompt, Tokens
• Domain Services for complex business logic (Provider Factory, Routing Strategies)

Technical Implementation:

• Multi-provider adapters (OpenAI, Anthropic, Google Gemini) with unified interface
• Intelligent routing strategies: cost optimization, quality prioritization, speed optimization
• Application layer with use cases, DTOs, and cross-cutting concerns (cache, retry decorators)
• Infrastructure layer with adapters for external systems (cache, persistence, providers)
• Comprehensive test coverage following testing pyramid

Tech Stack: Python, FastAPI, Domain-Driven Design, Hexagonal Architecture, Poetry, pytest

Why This Matters: Demonstrates ability to architect complex systems following enterprise patterns, separating business logic from infrastructure concerns, and building maintainable, testable code at scale.

Production-ready Django middleware providing comprehensive application monitoring with OpenTelemetry integration.

Features:

• Real-time metrics and distributed tracing
• Database query performance monitoring
• Prometheus, Loki & Tempo integration
• Production-tested on high-traffic systems

Impact: Actively used in production environments, helping teams gain visibility into Django application performance

• Associate DevOps Certification - Arvan Cloud (2025)
• FastAPI Certification - Maktabkhooneh (2025)
• Linux Operating System - Maktabkhooneh (2022)
• Django Rest Framework Developer (DDC) - Maktabkhooneh (2023)
• Python Web Developer (PWD) - Laitec (2021)

I maintain django-observability, an open-source monitoring solution for Django applications with active users in production environments.

Open to:

• Open source collaboration on DevOps and backend infrastructure projects
• Technical consulting for system architecture and scalability challenges
• Speaking engagements on DDD, Hexagonal Architecture, or DevOps practices
• Mentoring backend engineers transitioning to senior roles
