Wiregate Project Maintenance
Highly recommended! The Wiregate team delivers on time, does the work the right way and always clearly communicates.
We continue to use them for maintenance and it's not a question that will use them again for new projects in the future as they are needed.

Beyond building from the ground up, I specialize in jumping into existing codebases to stabilize and scale them. Whether you are dealing with technical debt, legacy systems, or performance bottlenecks, I provide deep-dive audits, refactoring, and feature optimization to ensure your current product is production-ready and built to handle increasing user loads.
I’m a senior full stack engineer working with React, Node.js, Python, and PHP. In my work, I focus on building real products end-to-end, from idea to production, with full ownership and predictable delivery.
I work primarily as a full stack engineer specializing in React and Node, building modern web applications using React, Next.js, and Node.js. On the backend, I also work as a full stack engineer with Python and PHP, choosing the right stack based on the product and scaling needs.
