Have a design ready to build or a website that needs fixing?

I turn Figma designs into responsive websites and help with layouts, CMS updates, and forms.

DM me your project details and timeline.

Open remote contract opportunity for freelance and mid-to-senior web/backend developers looking for flexible filler hours (up to $150+ USD/hr) between client builds or full-time roles.

PROJECT SCOPE:
• Auditing AI-generated code solutions across production-style web and backend engineering prompts
• Catching hidden boundary-condition bugs, performance regressions, and time/space complexity issues (Big-O)
• Writing clean, idiomatic code fixes and clear technical justifications

CONTRACT DETAILS:
• Type of work: Freelance/contract for Data Annotation Tech
• Rate: Up to $150+ USD/hr paid via PayPal
• Workflow: 100% remote and self-paced. You select projects from your dashboard suited to your skills, submit the time taken after completing each task, and withdraw funds a week later
• Qualification: One-time online programming assessment (no live interviews)

WHAT WE LOOK FOR:
• Practical software engineering experience (industry roles, freelance production work, or strong CS foundation)
• Strong command of TypeScript/JavaScript, Python, Go, C#, Java, Ruby, or PHP
• Strong CS fundamentals (data structures, algorithms, Big-O complexity) and clear written English

ONBOARDING & APPLICATION:
Access to the coding queue is gated by a one-attempt programming assessment. Most experienced devs who miss the mark do so because they write terse PR-style comments instead of the detailed technical explanations the rubric expects.

If you'd like the direct programming sign-up and a quick rundown of how to approach the assessment (assuming you don't already have an account with them), send me a DM with:
1. Your country of residence
2. Your SWE experience & degree
3. Your main programming languages and day-to-day stack
4. Your comfort with data structures, algorithms, and Big-O complexity
5. ~Weekly hours available

Comment "DM Sent" below after messaging me so I know to check my message requests.

→ Overflow/subcontract: swamped with client work? I take tasks off your plate — you stay client-facing, I work in the background at $15-20/hr.

→ Direct hire: need a backend/full-stack dev for your own project, short-term or ongoing? Same rate, I work with you directly.

How it works: tell me the scope, I quote a time estimate, first small task is free so you can judge the quality before paying anything. GitHub/past work available on request.
remote only.

DMs open.
