Hi, I'm Mickael Douabin
Freelance Developer & Entrepreneur
10+ years building high-performance web & mobile applications. I combine deep technical expertise with a business-first mindset to deliver products that scale.
What I Do
Technical Expertise
A deep, hands-on skill set covering the full stack -- from mobile apps to cloud infrastructure and AI.
React.js
Building interactive, high-performance single-page applications and complex UIs with React. Component-driven architecture, state management (Redux, Zustand, Context), and performance optimization.
React Native
Cross-platform mobile development for iOS & Android from a single codebase. Native bridges with Kotlin/Swift, CI/CD pipelines with Bitrise & GitLab CI, and app store deployment.
Next.js
Full-stack web applications with Next.js: server-side rendering, API routes, static site generation, and edge functions. Optimized for SEO, performance, and developer experience.
AWS
Serverless architecture design and deployment on AWS. Lambda, DynamoDB, S3, API Gateway, CloudFront, and infrastructure as code. Scalable systems with zero server management overhead.
AI Integration
Integrating AI capabilities into web and mobile applications: LLM-powered features, recommendation systems, intelligent search, chatbots, and automated workflows using OpenAI, Langchain, and custom models.
