Full-Stack Engineer · Readiness AI · Founder, Turnover Ledger · Calgary
Complex software gets expensive when defects linger, releases are risky, and important workflows are difficult to change. I work across frontend applications, APIs, databases, integrations, testing, and release operations to help teams reduce that friction and ship dependable improvements. I am also the founder of Turnover Ledger.
Open to full-stack, software engineering, platform engineering, and technical product opportunities in Calgary and across Canada.
