Senior Software Engineer · Python backends · Fintech · SRE

I build scalable, reliable backend systems in Python, and I know my way around SRE tools and technology. This blog is where I write down what I learn.

$ cat about.md

I’m a senior software engineer with 8 years of experience in Python-based backend development and distributed application design. I build scalable, high-performance systems with Python, Django and FastAPI, with a focus on microservices, RESTful APIs and database optimization.

I’ve worked in fintech and enterprise environments, designing reliable, secure and cloud-ready systems. I’m also knowledgeable in SRE tools and technology: Kubernetes, CI/CD pipelines, production monitoring and keeping services available.
