Full-Stack Developer / QA Tester Needed for Web & Mobile App Testing

I’m looking for a reliable, experienced full-stack developer with strong QA/testing skills to test several web and mobile applications.

This is not a basic “click around and report bugs” role. I need someone who understands both the front end and back end and can identify whether an issue is related to UI, application logic, APIs, database behavior, authentication, permissions, integrations, or other technical causes.

Responsibilities

* Perform complete front-end and back-end application testing
* Test user flows from beginning to end
* Identify bugs, broken functionality, edge cases, and inconsistent behavior
* Test authentication, user roles, permissions, forms, database interactions, and APIs
* Test responsive/mobile behavior
* Reproduce bugs consistently and document the steps
* Provide screenshots or screen recordings when appropriate
* Clearly explain expected behavior vs. actual behavior
* Identify the likely source of technical issues when possible
* Retest fixes and confirm that issues have been resolved

Requirements

* Strong full-stack development experience
* Experience testing production or pre-production applications
* Understanding of APIs, databases, authentication, and role-based permissions
* Ability to inspect browser console/network errors and troubleshoot technical issues
* Strong attention to detail
* Clear written English
* Reliable communication
* Able to meet agreed deadlines
* Must provide regular progress updates while actively working on a project

Experience with React, Supabase, JavaScript/TypeScript, PWAs, native mobile apps, APIs, and SaaS platforms is especially helpful.

Communication Expectations

Communication and reliability are extremely important.

I need someone who:

* Responds consistently during agreed working hours
* Communicates immediately if there is a blocker
* Does not disappear during an active project
* Gives realistic deadlines and meets them
* Lets me know in advance about scheduled days off or availability changes

I do not expect someone to be available 24/7, but I do expect professional communication and dependable turnaround.

Potential for Ongoing Work

This can become an ongoing relationship. I have multiple applications that will require continued testing as new features and updates are released.

To Apply

Please include:

1. Your full-stack development experience
2. Your QA/application testing experience
3. Technologies you are strongest with
4. An example of a difficult application bug you discovered and how you diagnosed it
5. Your normal working hours and timezone
6. Your typical response time during working hours
7. Your hourly rate

Please begin your proposal with the words “FULL STACK QA” so I know you read the entire posting.

I’m looking for someone dependable, technical, detail-oriented, and interested in becoming my go-to person for application testing.
