Project details
Is your codebase ready to scale, or is technical debt holding it back?
I provide a professional code review to identify risks early and help you make confident technical decisions.
As an experienced full stack developer, react developer, node.js developer, backend developer, web developer, and javascript developer, I review both frontend and backend web codebases with a strong focus on architecture, performance, security, and maintainability. You’ll receive clear, actionable feedback - not generic advice.
This service is ideal if you’re working on a web application and want a reliable second opinion before launching or scaling.
I analyze project structure, API design, and overall implementation quality, then deliver a detailed, clear written report.
Please note: this code review is provided only for web applications. I do not offer code reviews as a mobile app developer, react native developer, wordpress developer, or python developer within this project. Mobile, React Native, WordPress, and Python-based codebases are outside the scope.
This is a review-only service and does not include feature development or refactoring.
Follow-up implementation can be discussed separately.

Full Stack Developer with Design Expertise Needed for WordPress-based Investment Community
I had worked with Serhiy before. This was a follow-up contract. My previous experiences got confirmed: Serhiy delivers high quality work, thinks through projects from a higher level, and is a very reliable and communicative partner throughout the whole process. He meets deadlines, flags potential issues proactively before they become problems, and he is careful and aware that his results align with the bigger picture. Working with Serhiy is enjoyable — he is responsive, and easy to collaborate with. I highly recommend him and am looking forward to work with him next time.

Hi 👋
I am a full stack developer, focused on building, improving, and scaling web-based products.
My expertise is focused on web platforms and web applications, where I deliver the highest quality and long-term value.
‼️ I specialize in long-term, in-depth full stack projects that require real expertise - not quick fixes. Projects where attention to detail, information architecture, clean code, and technical ownership actually matter.
💡 Where my expertise brings the most value:
➤ I’m typically brought in as a full stack developer to design and build products end-to-end, with a structured, scalable codebase and a clear connection between frontend and backend.
➤ As a react developer, I focus on building complex dashboards, data-driven interfaces, and UI architecture that stays predictable and maintainable as the product grows.
➤ As a node.js developer, I develop APIs, integrations, and backend services that support business logic and ensure long-term system stability.
🚀 What you get working with an experienced engineer:
✅ As a full stack developer, I focus on building systems that remain scalable, maintainable, and easy to extend as your product grows.
✅ As a react developer, I create interfaces that are not only visually polished but also structured for long-term development - making future iterations faster and more predictable.
✅ As a node.js developer, I design backend services and APIs with stability and performance in mind, ensuring your platform can support real users, real traffic, and real business operations.
🛠️ My full stack developer tech stack:
✔ React
✔ Next.js
✔ Node.js
✔ Nest.js
✔ JavaScript
✔ TypeScript
✔ Tailwind
✔ React Native
✔ MongoDB
✔ PostgreSQL
✔ MySQL
✔ WordPress
✔ PHP
✔ Git, GitHub, GitLab, Bitbucket
✔ Jira, ClickUp, Trello, Asana
🧠 Professional background and technical focus:
→ As a web developer with strong experience as a wordpress developer, I build and evolve complex web platforms across different business domains.
→ My background as a javascript developer allows me to work confidently with modern frontend frameworks and structured UI architectures, while my experience as a backend developer helps me design reliable systems, APIs, and integrations that support real business logic
→ I also have some experience as a react native developer, which gives me a general understanding of cross-platform product architecture and performance considerations
→ My experience as a python developer and a mobile app developer is limited, and my primary focus is on web-based products and full stack web development
🤝 Why should you work with me? I guarantee:
➤ Attention to detail;
➤ Perform your project in a great way.
➤ Fast and professional work;
➤ Meeting deadlines;
