Full Stack Software Developer
Medical appointments · the clinic scheduled by hand
Patients register and book on their own; the front desk manages weekday agendas, practitioners and health coverage. Each appointment moves through a state machine, with overbooking capped per day and per block.
Demo · coming soon
TestsIntegration tests against a real database — Jest and Supertest.
Short-term rentals · the agency ran on spreadsheets
Properties with galleries, availability search, payments that get voided instead of deleted, and early terminations whose penalty settles together with the reservation closing, in a single transaction.
Demo · coming soon
TestsNo automated tests.
Own Pomodoro timer · no app did what I needed
Block planning with the task assigned before starting, guided breaks, and a timer that stays accurate when the tab drops to the background: it advances by real elapsed time, with the tick in a worker and the end persisted.
