Project history
Took on engineering management responsibilities after a year, leading 3 engineers. Fostered a product mindset within the team, encouraging engineers to challenge assumptions and question pre-decided solutions from product/business stakeholders. Advocated for small, incremental steps to validate ideas early. Applied TDD, DDD, hexagonal architecture, mob/pair programming, and Dora Metrics (10min lead time, 15 deployments/week).
Full Stack Developer and Project/Product Manager. Built a B2C reservations site for a trekking routes business using Django (Python). Also worked with Blazor Server, MudBlazor (Material Design based), .NET Core, and CQRS.
Led the Lending team for a gig-economy financial services app operating in Mexico, Chile, and Peru. Drove lean, rapid iterations and introduced low-code/no-code tools to accelerate delivery.
