About

Senior Backend Engineer specialising in Django, with 10+ years of experience designing, building and operating production systems in Python across cloud environments. I focus on improving and refactoring legacy systems, simplifying complex codebases and increasing the reliability of long-lived production environments. Experienced with AWS and GCP, CI/CD automation, containerised deployments and production infrastructure. I have also worked with FastAPI to build lightweight, service-oriented APIs. I also work with Vue.js when frontend contribution is needed and contribute across the stack where it improves overall system quality. Worked on scalable platforms during high-growth phases, supporting increased traffic and system complexity. Interested in Backend, Platform or Backend-leaning Full-Stack roles.
