You will get a React TypeScript feature built for your web app
Project details
You will get a custom React and TypeScript feature built for your web application, SaaS platform, dashboard, portal, or internal business tool.
This project is ideal if you need a new frontend component, form workflow, dashboard section, API-connected feature, UI bug fix, responsive layout improvement, or frontend module added to an existing application.
Depending on your package, I can build reusable React components, connect the frontend to backend APIs, implement form validation, improve user flows, clean up existing UI code, and provide source code with handoff notes.
I can work from Figma designs, screenshots, wireframes, written requirements, user stories, or an existing codebase. Before development begins, I will review your requirements, current app structure, API needs, and expected user behavior so the final feature fits your application and business workflow.

About Devin
Senior Backend & Full-Stack Engineer | APIs, SaaS, AI Fortune 100
Charlotte, United States - 6:52 pm local time
I help businesses turn software ideas, broken systems, and stalled development work into production-ready applications.
I’m a senior software engineer with experience building and maintaining enterprise software for Fortune 100/Fortune 30 environments, including platforms involving React, TypeScript, Java/Spring Boot, Go, MongoDB, REST APIs, cloud services, integrations, automation, and AI-augmented workflows.
Clients usually come to me when they need someone who can step into complexity quickly, understand the business problem, and deliver clean, maintainable software without needing constant hand-holding.
What I can help with
* Full-stack web application development
* Backend API development with Java/Spring Boot, Go, Node.js, and REST
* React, TypeScript, Angular, and frontend component development
* MongoDB and SQL database design, queries, and data workflows
* SaaS MVP development and feature implementation
* API integrations, third-party services, and internal tools
* AI-assisted software workflows, automation, and productivity tooling
* Debugging, refactoring, performance improvement, and technical cleanup
* QA regression planning, test strategy, and release readiness
* Technical documentation, architecture planning, and backlog creation
Why work with me
I bring more than coding ability. I understand software delivery from both the engineering and business side. I can work from a rough idea, a Figma design, a backlog, an existing codebase, or a messy production issue and turn it into a clear execution plan.
I’ve worked across enterprise systems where reliability, maintainability, security, and clear communication matter. I’m comfortable collaborating with product managers, designers, QA teams, business stakeholders, and other engineers.
Common projects I’m a good fit for
* “We need an MVP built.”
* “Our current developer left, and we need someone to take over.”
* “Our React app needs new features or cleanup.”
* “We need backend APIs built or fixed.”
* “We need help integrating AI into our workflow.”
* “We need a technical person to turn requirements into tickets.”
* “We need production-level software, not just a prototype.”
## Tech stack
React, TypeScript, JavaScript, Angular, Java, Spring Boot, Go, Node.js, Express, MongoDB, SQL, REST APIs, Git, Docker, CI/CD, cloud services, API integrations, testing, automation, and AI-assisted development workflows.
If you need a reliable engineer who can understand the problem, communicate clearly, and move the project forward, send me a message, and I’ll help you map out the next step.
