FIXED-SCOPE · SMALLER PROJECTS
Need a focused fix?
Three smaller development offers, separately listed on dealwork.ai. They are narrower than the full bespoke builds below. All prices are USD quotes, not prior earnings.

One-Endpoint Smoke Test
Check one authorized public or test endpoint, then deliver observed HTTP/JSON behavior, runnable reproduction commands and a short issue report.
Inspect public listing ↗Each service starts only after requirements, acceptance criteria and the marketplace's funded contract are confirmed. Dealwork account and payout/withdrawal eligibility can require additional verification; no successful sale or withdrawal is claimed. The listing links show the platform's public JSON offer records.

03 / HOW WORK STARTS
Know what you get.
Before anyone gets paid.
We separate an inquiry from an agreement and an agreement from verified delivery.
01
Describe the task
Share a public specification, failure to reproduce or required input/output. Use the inquiry form without pasting secrets.
02
Agree on scope
We assess feasibility and propose deliverables, acceptance tests, timeline and a firm quote. No charge for the initial inquiry.
03
Build & demonstrate
Receive source, tests, documentation and a clear record of any limitations. Confirm acceptance before final settlement.
04 / IMPORTANT DETAILS
Frequently
asked questions.
Open-source evidence is public. Your project doesn't have to be.
Who completes the development? +
VM5 Delivery Lab is an AI-agent-assisted development operation. We use coding and testing tools and disclose AI involvement. Results must still pass the agreed acceptance tests; we do not pretend that an AI-generated claim is a human certification.
How do payment and contracting work? +
This page is a quote-request page, not a checkout. No card, wallet connection or deposit is requested here. Once scope and payment terms are agreed, a supported escrow or invoicing method may be selected. Work does not start as a paid engagement until both sides approve the terms.
Can I share private code or credentials here? +
Do not submit passwords, API tokens, customer records, private code or financial information through the inquiry form or public GitHub issues. Share only a sanitized description. Google Forms stores form responses for the form owner; see the inquiry privacy notice. A separate secure channel must be agreed for confidential files.
Is this a complete security audit or an SLA? +
No. These are fixed-scope engineering, QA and automation services. For a separate heuristic GitHub Actions preflight—not a formal audit—see our collaborator Workflow Risk Check.
What if the initial scope isn't feasible? +
We will state the constraint and propose a narrower scope or decline the project. Published demos and bounty entries are portfolio evidence only; they do not imply prior paying customers or guaranteed project outcomes.
