You will get a full code audit and refactor of your React or Node.js app
Project details
Inherited a messy codebase, or worried your app won't scale? I'll audit your React, Node.js, TypeScript or Laravel project – code quality, architecture, security, and performance – and hand you a clear, prioritized report of what to fix and why. Need it done, not just documented? The Standard and Advanced tiers include the fixes, delivered as a clean pull request. Best fit for small to mid-size codebases – large or multi-service platforms are scoped separately, so just message me first.

About Artur
Senior Full-Stack Developer | React, NodeJs, TypeScript | Laravel, AWS
100%
Job Success
Kyiv, Ukraine - 1:48 am local time
Hi, I'm Artur - a senior full-stack web developer with 14 years building, scaling, and maintaining production web and mobile applications. With 10,000+ hours and $300K+ earned on Upwork at a 100% Job Success score, I've delivered a small number of long-term, high-trust engagements rather than one-off gigs - the kind of partnership where I own a product end to end and it keeps growing.
What I do:
• Full-stack web apps - React, Vue.js, Angular, and TypeScript on the front end; Node.js, Express, NestJS, and PHP/Laravel on the back end.
• APIs & integrations - REST and GraphQL APIs, third-party API integration, and backend services built to stay fast under real load.
• Data-heavy features - analytics and processing of large volumes of data, backed by MySQL, PostgreSQL, MongoDB, Firebase, Redis, and DynamoDB.
• Mobile & cross-platform - React Native and Electron apps from a shared codebase.
• DevOps & cloud - AWS (EC2, S3, SES, Route 53, load balancing), Heroku, and DigitalOcean, so what I build ships reliably and scales.
How I work:
I start from the outcome you actually need, not just the ticket. You get clear communication, honest estimates, clean and maintainable code, and steady progress you can see week to week. I'm equally comfortable owning a greenfield build, joining an existing team, or rescuing a stalled project and getting it back on track.
A strong fit for:
- SaaS platforms, dashboards, and internal tools
- Custom web applications from idea to launch
- API and backend development / third-party integrations
- Performance, scaling, and refactoring of existing apps
- Cross-platform mobile apps
Tech I use daily: JavaScript, TypeScript, React, React Native, Vue.js, Angular, Node.js, Express, NestJS, PHP, Laravel, GraphQL, REST APIs, MySQL, PostgreSQL, MongoDB, Firebase, Redis, DynamoDB, AWS, and Git.
Why clients keep coming back: a 100% Job Success record, 14 years in the field, and long-running engagements where the same client returns for the next phase. I treat your product like my own - reliable, communicative, and invested in it actually working.
If you need a senior developer who can take a project from idea to launch and keep improving it, send me a message with a few details about what you're building. I'll reply with honest thoughts on scope, approach, and timeline. Let's talk.
