I will develop react and typescript features for your web application
Usman
About this gig
Turn your product specification into a tested feature in your web application.
I'm a UK-based, full-time software developer with two years of professional experience. I work with React, TypeScript, APIs and automated testing.
I build internal-tool screens, customer workflows and API-connected interfaces within your existing application, following your design and component system. Delivery covers validation, loading and error states, responsive behaviour, source code, setup notes and tests for agreed user journeys.
The full-stack package can include a small backend module and CI test workflow in your existing repository.
Have a custom requirement? Send your specification before ordering. I review the codebase, clarify the screens and data contracts, and agree deliverables, acceptance criteria, exclusions, price and timeline. If a package does not fit, I can prepare a tailored Fiverr offer.
Packages cover one defined feature. Full SaaS builds, new login systems, payments, substantial design work and ongoing hosting require separate scoping.
Message me with your brief, repository details and design to confirm scope and availability.

FAQ
Can you quote from my own specification?
Yes. Send your brief, user journeys, designs and repository details before ordering. I clarify requirements and assess feasibility, then agree deliverables, exclusions, acceptance tests and schedule. Work outside these packages receives a tailored Fiverr offer after scope review.
Do I need an existing application and design?
Yes. These packages extend a runnable React/TypeScript application using your supplied designs or component system. I review the repository and compatibility before ordering. New applications, substantial redesigns and complex editors or data grids require separate scoping.
What do the packages include?
Basic: 1 screen, 1 existing API operation and 1 journey test. Standard: up to 3 screens, 3 existing operations and 3 tests. Premium: up to 3 screens, 4 operations, 2 backend models, 5 tests and CI setup. All cover one agreed feature.
What counts as a screen or API operation?
A screen is one agreed route or distinct interface view. An API operation is one HTTP method and path. We agree annotated screens, data contracts, component behaviour and business rules before development. Additional workflows need a separate quote.
How will the feature be tested?
I add tests for agreed user journeys and run relevant project checks. Responsive checks cover agreed desktop and mobile Chromium sizes. Handover lists results, existing failures and limitations. This does not guarantee the whole application is bug-free.
Are authentication, payments and hosting included?
Packages can reuse existing authentication and APIs. New login systems, payment processing, production migrations, hosting fees and ongoing maintenance are excluded. Any deployment or additional integration must be scoped separately.
What does the revision include?
One consolidated round within agreed acceptance criteria. New screens, workflows or changed requirements need a separate quote. Includes 7 days of handover questions, up to 30 minutes. Reproducible defects against the agreed scope will be addressed.
