About Sritharan

I am Sritharan (Sri), a Senior Software Architect based in Mol, Belgium, with over 17 years of hands-on experience designing and operating production-grade systems. I specialize in turning "spaghetti code" and operational chaos into stable, scalable, and automated platforms.

How I can help you:

Platform Architecture: Designing cloud-native microservices that scale predictably (AWS/Azure).

Backend Engineering: Building robust APIs and heavy-lifting background workers using Python (FastAPI, Django).

DevOps & Reliability: Setting up Kubernetes, Docker, and CI/CD pipelines so you can deploy without fear.

Legacy Modernization: Transforming old PHP/Monolithic systems into modern, maintainable architectures.

Tech Stack:

Languages: Python (Expert), PHP (Legacy migration)

Core: FastAPI, Django, PostgreSQL, Redis

Infra: Kubernetes, Docker, Terraform, AWS, Azure

Async: RabbitMQ, Celery, Kafka (Event-Driven Systems)

I speak fluent English and Dutch. Whether you need a strategic architect to guide your team or a hands-on engineer to build the core of your platform, I deliver production-ready results.

Let's discuss your challenge. Feel free to book a call.
