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.

Skills & Services
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
▸ Backend: Node.js, Python, PHP, Laravel, Express
▸ Frontend: React, Next.js, JavaScript
▸ Databases: PostgreSQL, MySQL, MongoDB
▸ APIs: REST APIs, third-party integrations
▸ DevOps: AWS, Docker, CI/CD
As a full stack engineer (Node.js/Python), I build robust APIs, business logic, and complex integrations. As a full stack engineer (React/Next.js), I build fast, clean, and scalable interfaces.
I often lead full stack engineer React Node projects, connecting frontend and backend into a single reliable system. I also take on PHP projects when stability and speed of delivery are critical.

How I Work as a Full Stack Engineer
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
As an experienced full stack developer, I focus on:
– Clean and scalable architecture
– Fast frontend with React and Next.js
– Stable backend with Node.js, Python, or PHP
– Production-ready delivery
I can join as a full stack engineer or take a broader role with total ownership over architecture and execution.
Beyond standard engineering, I bring the comprehensive mindset of a senior web developer to modernizing legacy systems. For instance, if your platform was originally built by a WordPress developer and is now struggling to scale, I specialize in migrating those monolithic systems into custom, high-performance architectures. If your business has outgrown what a standard WordPress developer can provide, I can rebuild your platform from scratch. As a React developer, I transform outdated interfaces into blazing-fast web apps.
Additionally, while I am not a native mobile app developer, I regularly collaborate with your mobile app developer team by building the robust backend infrastructure and optimized REST/GraphQL APIs they need. Every professional web developer knows that a great frontend depends on a solid backend, so I ensure that your mobile app developer gets seamless, well-documented endpoints, while I focus on the web ecosystem as a dedicated React developer.
Ultimately, whether you are transitioning away from a legacy WordPress developer setup, looking for a web developer to build enterprise-grade systems, or need a React developer who knows how to support a mobile app developer, I deliver clean, production-ready code.
