About Kipkemoi
I'm a Senior Full stack Engineer who bridges development, DevOps, and Cybersecurity to build applications that are secure, scalable, and cloud-ready from the ground up.
I offer website and web application development services, hosting, server configurations, website rebuilding and redesign.
Technical stack:
Next.js, React Native, React, TypeScript, Node.js, Express.js, Laravel, Python, MongoDB, and PostgreSQL. I deliver everything from lightweight REST APIs to full-scale web applications. I also do web development using WordPress, Elementor and hosting using Hostinger, Namecheap.
Security is engineered from the start — secure authentication, hardened APIs, encrypted payment pipelines, and safe deployment practices. I test with Playwright and Postman, and manage workflows with GitHub.
Infrastructure & DevOps:
I own the full deployment lifecycle. I configure Apache and Nginx as web servers and reverse proxies, manage Node.js processes with PM2, and containerize applications with Docker. I deploy and scale on AWS, Digital Ocean, Vercel, Heroku, and private servers and VPS environments.
What sets me apart:
I operate at the intersection of development, DevOps, and operations. My cross-domain background — spanning business operations, software engineering, cybersecurity, and payment integrations — allows me to translate complex challenges into efficient, secure digital solutions.
Areas of focus:
• Secure, scalable full-stack web applications
• Payment integration and financial workflows
• Cloud infrastructure and production deployment
• Logistics, inventory, and operational systems
• Software quality through testing and best practices
• Automation using Make.com, Notion, PowerAutomate
• AI expert, webmasters, web expert, SEO, SSL and hosting configurations
Open to collaboration. Ready to build.
