@jeremysavage
Senior backend engineer specializing in scalable systems and data platforms.
United KingdomWhat I'm looking for
I am a Senior Backend Engineer with over six years of experience in delivering scalable systems, primarily using Python, FastAPI, and SQLAlchemy. My expertise lies in backend and data platform engineering, particularly for mission-driven companies. I have a proven track record of optimizing ELT pipelines, automating CI/CD processes, and mentoring teams to achieve high standards of delivery.
At Ensemble Analytics, I developed a backend for a staff scheduling platform that manages 7% of UK sea imports, scaling operations from zero to over 2000 scheduled staff daily. I also built a BI tool for real-time analytics, which implemented overtime cost optimization, saving the company an estimated £1M annually. My commitment to quality is evident in my leadership of CI/CD adoption and Test-Driven Development (TDD), where I increased test coverage from zero to 1200 unit tests.
Throughout my career, I have worked on various projects, including building AI-driven applications and leading data warehouse development for major organizations. I am passionate about using technology to solve complex problems and am dedicated to mentoring the next generation of developers.
