ABOUT ME
Software Engineer
Software Engineer
Experienced team lead with a technical foundation in software architecture, data engineering, and cloud infrastructure, enhanced by a background in Behavioural Psychology. I combine these dual perspectives in translating visionary concepts into human-centred, data-driven products.
I initially built Rentgrata's flagship widget, increasing conversion by 163% post-launch. Later, as team lead for Ari (Actional Rental Insights)—the world’s first conversational AI engine for multifamily rental insights—I oversaw technical details and code implementation, ensuring successful delivery.
As a team lead, I foster collaboration and innovation, guiding teams to engineer solutions that meet and exceed business objectives, ensuring autonomy and excellence in execution.
