Backend engineer specializing in billing systems and payment infrastructure.
In my current role, I built an ISP billing backend end-to-end as the sole engineer designing the architecture, integrating payment gateways, and automating service provisioning. The result: activation time dropped from ~5 minutes to 10–20 seconds, and manual provisioning was eliminated entirely.
My stack: Python, PostgreSQL, Redis, RabbitMQ, Docker. I write idempotent webhook handlers, design outbox patterns for reliable event delivery, and optimize queries for high-traffic billing reports.
I work well independently, communicate proactively, and ship systems that stay stable under load, not just code that works on my machine.
Looking for backend or full-stack roles where reliability and payment/billing domain knowledge actually matter.
