About

Professional summary

I am a Full Stack Software Engineer with over five years of programming experience building reliable JavaScript and TypeScript applications. I specialize in creating responsive, user-focused web products with React, Next.js, Node.js, and Express.

I build end-to-end SaaS solutions, from reusable frontend components and dashboards to backend APIs, authentication, database integrations, and cloud deployments. My work includes REST APIs, asynchronous programming, real-time workflows, payments, and third-party integrations.

As the founder of CodeWithEmmy, I have delivered more than 25 software solutions for over 15 clients. I enjoy translating business requirements into practical, maintainable features that support real user and operational needs.

I am experienced with production systems using PostgreSQL, MongoDB, Redis, Docker, Vercel, Git, automated testing, and CI/CD workflows. I prioritize debugging, code quality, API documentation, and dependable delivery.

I also teach JavaScript and React, helping learners understand software development concepts clearly. I work effectively both independently and in cross-functional remote teams, combining technical delivery with clear communication.
