Back to original languageAbout Perry-Keanou
Fullstack Developer Designer | TypeScript & Algorithmics.
My code is not just functional, it's optimized.
Coming from a rigorous industrial background, I have maintained iron discipline that I now apply to web/mobile development. I don't just "make an application work": I build it on solid algorithmic foundations.
Industrial Rigor: I respect deadlines and specifications with surgical precision.
I practice algorithmics every day (Complexity, Data Structures) to keep a sharp mind and a complex problem-solving ability.
My practice of the C language gives me a head start in understanding what happens under the hood (memory management, pointers), making my TypeScript code more performant and cleaner.
Open Source: Creation of a TypeScript library (coming soon on NPM) aimed at optimizing recurring data processing processes.
Flagship Project: PetFosterConnect
Complete development of a connection platform for animal foster families (available on my GitHub). A project where business logic and data security were my priorities.
Development of a complete mobile application in Monorepo (React Native & NestJS stack with Nx).
I am designing this project from scratch using Nx to ensure a modular and scalable architecture. I manage the entire lifecycle:
Data Modeling (Merise method).
Robust REST API with NestJS and Prisma.
Fluid interface under React Native.
Using a Monorepo allows me to maintain perfect consistency between the Front and the Back through TypeScript type sharing, thus ensuring simplified maintenance and high-quality code.
Curious to see more? I would be delighted to show you the project architecture and the final result during a private discussion.
