Unified fragmented systems into a performant microservice-based architecture customized for prop trading operations. Architected domain-based services using .NET Core, NestJS, MongoDB, and MySQL, aligned with SOLID principles and modular domain isolation. Deployed and managed infrastructure using Docker, Kubernetes, and OcelotAPI Gateway, ensuring zero-downtime deployments and fault tolerance. Integrated ChatGPT-powered AI support bot using FastAPI, Rasa, and PostgreSQL, automating ticket workflows and reducing live agent dependency by 60%. Orchestrated CI/CD pipelines in Azure DevOps, enabling automated builds, testing, and production-grade deliverywith version controlled rollback strategies. Managed and optimized 200+ Linux-based MetaTrader instances using Wine, sustaining 99.9% uptime under loads of 200K+ concurrent users.

Architected a multi-tenant chatbot builder using FastAPI backend and React frontend. Integrated ChatGPT APIs with Rasa NLU for real-time NLP, and built dynamic AI logic with PostgreSQL + embeddings. Developed onboarding wizard, role-based access, and multi-language support. Implemented CI/CD with Docker Compose, Traefik, and Nginx for automated deployments across tenants.

Directedthestrategicrefactoringandmodernizationoftwoflagshipdigitalplatforms(Anten&Varzesh3). Re-architected Anten's legacy SSR .NET system to a modern React + MongoDB SPA with asynchronous data flow. Refactored Varzesh3's monolithic backend into modular .NET Core services, aligning for future microservice deployment. Led 7 engineers across Agile sprints, DevOps integration (GitHub Actions, Docker), and version-controlled releases. Reduced CI/CD cycle time by 60%, improving delivery speed, rollback safety, and deployment reliability.
