If your app is broken, behind schedule, or stuck with bugs you can’t diagnose, I can help. I’m a senior full-stack developer with 30+ years of experience fixing, stabilizing, and finishing production systems—especially React, Node.js, APIs, and databases. I’m often brought in when: • A project is partially built but stuck • A previous developer disappeared • Bugs are blocking launch • APIs or integrations aren’t working My focus is fast diagnosis, clear communication, and shipping fixes—not rewrites. I’m a hands-on developer with 35 years of experience delivering production software across web, backend, and infrastructure systems. In recent work, I’ve been building and fixing applications using React, Node.js, MongoDB, and modern cloud environments. I also work with Web3 systems when needed, including Ethereum and Solana smart contracts, token integrations, and wallet-based workflows. With experience across many languages and platforms, I adapt quickly to the problem at hand and focus on getting things working reliably. Common fixes I handle: • API integrations that fail, timeout, or return incorrect data • Third-party API auth, webhooks, and data sync issues • React rendering, state, and performance issues • Node.js / Express backend errors and crashes • MongoDB schema, query, and data issues • Finishing half-built MVPs I’m available for short-term fixes or ongoing support.

Code Refactoring Specialists Hiring FAQs

What is code refactoring?

Code refactoring is the practice of restructuring your code without changing its functionality, often for the purpose of making it clean, concise, and in accordance with development best practices. A code refactoring specialist can save you the trouble of refactoring your code yourself, giving you more time to focus on development of new features. 

How do you hire a code refactoring specialist?

You can source code refactoring talent on Upwork by following these three steps:

  • Write a project description. You’ll want to determine your scope of work and the skills and requirements you are looking for in code refactoring specialists.
  • Post it on Upwork. Once you’ve written a project description, post it to Upwork. Simply follow the prompts to help you input the information you collected to scope out your project.
  • Shortlist and interview code refactoring specialists. Once the proposals start coming in, create a shortlist of the professionals you want to interview. 

Of these three steps, your project description is where you will determine your scope of work and the specific type of code refactoring specialists you need to complete your project. 

How much does it cost to hire a code refactoring specialist?

Rates can vary due to many factors, including expertise and experience, location, and market conditions.

  • An experienced code refactoring specialist may command higher fees but also work faster, have more-specialized areas of expertise, and deliver higher-quality work.
  • A contractor who is still in the process of building a client base may price their code refactoring services more competitively. 

Which one is right for you will depend on the specifics of your project. 

How do you write a code refactoring job post?

Your job post is your chance to describe your project scope, budget, and talent needs. Although you don’t need a full job description as you would when hiring an employee, aim to provide enough detail for a contractor to know if they’re the right fit for the project.

Job post title

Create a simple title that describes exactly what you’re looking for. The idea is to target the keywords that your ideal candidate is likely to type into a job search bar to find your project. Here are some sample code refactoring job post titles:

  • Need help refactoring Java development code into production-ready code base
  • React developer needed for code refactoring UI components for production
  • Refactoring legacy Objective C code into Swift (iOS development)

Project description

An effective code refactoring job post should include: 

  • Scope of work: From technology migrations to production-ready code, list all the deliverables you’ll need. 
  • Project length: Your job post should indicate whether this is a smaller or larger project. 
  • Background: If you prefer experience with certain technologies, programming languages, or developer tools, mention this here. 
  • Budget: Set a budget and note your preference for hourly rates vs. fixed-price contracts.

Code refactoring specialist job responsibilities

Here are some examples of code refactoring specialist job responsibilities:

  • Refactor code from development environment into production-ready deployment
  • Write automated unit, integration, and end-to-end tests
  • Document all processes and code
  • Update code from legacy deployments to latest best practices

Code refactoring specialist job requirements and qualifications

Be sure to include any requirements and qualifications you’re looking for in a code refactoring specialist. Here are some examples:

  • Working knowledge of the desired programming language (e.g., C#, Swift, Java, JavaScript)
  • Experience with target technology ecosystem (e.g., React, Microsoft, iOS, Android)
  • Application development
