About

Hi, I’m Bejo Jeffrin 👋 With 6+ years of experience as a Senior Software Engineer, I specialize in building scalable, secure, and distributed web applications using the MERN Stack, Next.js, TypeScript, and Cloud Platforms (AWS & Azure). I was part of the founding team at CryptoSmartlife, where I helped shape the company’s technical foundation and contributed to its early growth. Prior to that, at Jamelah, I led full-stack development across multiple projects — from architecture and deployment to continuous delivery — ensuring clean, maintainable, and performant code. My technical toolkit includes: 🧩 Frontend: React.js, Next.js, React Native, Redux, React Query, Tailwind CSS ⚙️ Backend: Node.js, Express.js, MongoDB, PostgreSQL, WebSockets, Docker ☁️ DevOps / Cloud: AWS, Azure, Bitbucket CI/CD, Auth0, Amazon Cognito I’m passionate about building microservices architectures, exploring event-driven systems (Kafka), and designing solutions that scale reliably across cloud infrastructure. Beyond coding, I love collaborating with innovative teams, mentoring peers, and sharing insights on system design and modern web development. If you’re building something exciting in the cloud, let’s connect and explore how we can bring your ideas to life. 🚀
