What I'm looking for

I seek roles building scalable, cloud-native backend systems where I can improve reliability through automation, CI/CD, testing, and performance optimization.

I am a Senior Software Engineer with over 10 years of experience specializing in backend development using Golang and Python. I combine a Mathematical Civil Engineering background with practical cloud-native engineering to design high-concurrency web services and efficient microservices architectures.

Throughout my career I have led the development and deployment of mission-critical systems, introduced automated testing practices, and optimized backend performance and database interactions to reduce latency and improve reliability. I have delivered end-to-end solutions across telecommunications, banking automation, mining, and research environments.

I value scalable, maintainable systems and continuous improvement through automation and DevOps practices. I am focused on building reliable, high-performance software and mentoring teams to adopt robust testing, CI/CD, and cloud-native workflows.
