I’m Jisselin Djilo, or Cj for short. For close to six years I’ve been shipping front-ends and back-ends in Vue.js, React, Laravel and Node.js, for teams in France, the United States and Cameroon.
What sets me apart fits in one line: I write the tests too. Cypress, PHPUnit, Postman. The code I hand over has already been broken before it reaches production.
An e-invoicing platform for French companies. I took over the entire front-end: 30 to 60 screens built from Figma, plus a rewrite of the React architecture into a modular structure the whole team then adopted as its standard.
React · Zustand · Ant Design · Tailwind CSS · REST API · Cypress · Postman
An e-learning platform, 100% in French and 100% tech. I led the technical side: design, 100% of the front-end and back-office in Vue.js, part of the Node/Express back-end, and the payment integration.
Vue.js · Tailwind CSS · Pinia · Element Plus · Node.js · Express · MongoDB · REST API · PawaPay · Dodo Payments
A booking application for a serviced-apartment residence in Yaoundé. Public side: gallery, online booking, Mobile Money payment. Private side: a custom back-office (units, stays, payments, newsletter) behind role-based authentication.
Vue.js · Tailwind CSS · PrimeVue · Laravel · REST API · NotchPay · Postman · cURL
Does one of these look like what you’re building? Let’s take twenty minutes, no strings attached.
Book a slotMost developers stop when it works on their machine. I keep going: Cypress end-to-end tests, PHPUnit unit tests, API tests with Postman and cURL. On Melrys, Kesla and Cabinet Otti, the tests were part of the delivery, not of some later phase.
On Melrys I stopped shipping features to rewrite the React architecture mid-project. It was the wrong moment and it was the right call: the modular structure became the team’s standard, and a complete redesign of the mockups did not derail the deadline.
A gap between the mockup and the business logic costs ten minutes on Monday and three days on Friday. I raise inconsistencies the moment I see them, even when they’re outside my scope.
I code, I test, I document. The third is the one nobody brags about, and the one that decides whether your successor curses your name.
