At WisEdu, I designed, built, and deployed a multi-tenant school management platform now used by four schools, 250 teachers, and more than 3,000 students. I worked with teachers during a one-year pilot to understand school workflows and Ministry of Education rules before finalizing the design.
I built a grading engine and automated official MINERD documents. Teachers can submit validated grades from any device, replacing hand-summed grades and paper slips; the platform has recorded more than 131,000 grades.
At Trazza DMS, I built a dealer management system that’s live in production, with hundreds of sales per month. Its tax engine handles ITBIS, primera placa, and non-cascading discounts, while e-CF invoicing connects through the mSeller API.
At Banco BHD, I led a three-person team building a talent management system, delivering the frontend and much of the backend. I also configured internal banking integrations with Broadcom Layer 7 Policy Manager and worked under Scrum.
