Why Dev12
Destroys Fiverr

Fiverr is a noisy, bloated 2012 shopping mall filled with fake reviews, endless haggling, spam, and a soul-crushing 20% platform tax. Dev12 is high-end, zero-friction engineering.

                            a misaligned flexbox, or a failing Stripe webhook, and say:
                        
                            5
                            "I have £35 and zero patience. Someone fix this in the next two hours."

                            and ruthlessly cuts the fat out of freelance engineering.

The Codex Core State Machine

Milestones move through one secure path: funded work, sandbox submission, timed review, dispute control, then automatic payment and repository transfer.

State Boundary

Exact Milestone Enforcement

A milestone can exist in only one state at a time. Every mutation validates the current state before advancing the work or releasing money.

FUNDED → SUBMITTED → IN_REVIEW → RELEASED ← DISPUTED

FUNDED Client has paid the milestone budget plus the 3% escrow fee. Safe for the developer to begin.

SUBMITTED Developer has pushed code changes to the secure platform-managed repository layer.

IN_REVIEW The 5-day review window is ticking. Client can test builds and artifacts without production repository ownership.

DISPUTED A scoped issue or contested rejection requires admin arbitration before release.

RELEASED Stripe Connect clears the 88% / 12% + 3% split and repository ownership transfers to the client.

SQLite Schema

Milestone Ledger Table

The storage model tracks financial velocity, repository custody, review deadlines, and state transitions in one atomic record.

Column	Type	Constraint / Description
milestone_id	TEXT	Primary key UUID.
project_id	TEXT	Foreign key referencing projects(id).
developer_id	TEXT	Foreign key referencing users(id).
client_id	TEXT	Foreign key referencing users(id).
base_budget	REAL	Raw project value, for example 500.00.
client_fee	REAL	3% escrow processing fee, for example 15.00.
dev_fee	REAL	12% platform take-rate fee, for example 60.00.
current_state	TEXT	Restricted to FUNDED, SUBMITTED, IN_REVIEW, DISPUTED, RELEASED.
sandbox_repo_url	TEXT	Secure isolated platform repository endpoint.
production_repo_url	TEXT	Client destination repository endpoint.
auto_approve_at	INTEGER	Unix timestamp ending the 5-day review lock.

Routine A

submit_milestone_work()

Verify the state is exactly FUNDED.
Bind the sandbox commit hash to the milestone.
Set auto_approve_at to current_time + 432000.
Mutate to SUBMITTED and notify the client dashboard.

Routine B

trigger_auto_approval_check()

Query SUBMITTED or IN_REVIEW milestones past auto_approve_at.
Invoke the release pipeline for every expired review lock.
Prevent stalled client reviews from blocking developer payout.

Routine C

release_milestone_funds()

Verify IN_REVIEW, SUBMITTED, or admin-authorized DISPUTED state.
Transfer base_budget - dev_fee to the developer wallet.
Transfer dev_fee + client_fee to the Dev12 treasury.
On payment webhook success, mark RELEASED and sync repository ownership.

API Contracts & Ledger Flow

The dashboard never mutates milestone state directly. It calls narrow backend endpoints that validate state, write the ledger, and hand payment movement to Stripe Connect.

POST

/v1/milestones/{id}/fund

Triggered when the client pays £515 on a £500 job. The backend creates or confirms the Stripe hold and moves the milestone to FUNDED.

state: DRAFT/PENDING_PAYMENT -> FUNDED

POST

/v1/milestones/{id}/submit

Triggered when the developer pushes work to the sandbox layer. Requires a commit hash or artifact URL and starts the 5-day review lock.

{ "sandbox_commit_hash": "abc123", "artifact_url": "..." }

POST

/v1/milestones/{id}/approve

Triggered by the client or auto-expiry worker. It releases the escrow vault, executes the Stripe split, and moves the milestone to RELEASED.

actor: client | expiry_worker | admin

Stripe Connect

Ledger Architecture

Developer funds should move through Stripe Connect Custom or Express accounts. Dev12 records the platform fee, but the developer's 88% cut routes to their connected account rather than settling into the standard platform bank account.

Developer onboarding Each developer completes Stripe KYC and links a bank account as a Connected Account.

Payment intent tagging The client payment is tagged with a transfer_group matching milestone_id for clean ledger reconciliation.

Split execution Approval transfers £440.00 to the developer account on a £500 base budget; the remaining £75.00 settles to the platform ledger.

{
  "amount": 44000,
  "currency": "gbp",
  "destination": "acct_dev_connected_id",
  "transfer_group": "milestone_id"
}

Expiry Worker

Cron / Queue Release Guard

A lightweight background service watches auto_approve_at. If the client is silent for 5 days after submission, the worker passes the milestone_id to the same release engine used by manual approval.

Poll eligible milestones Find SUBMITTED or IN_REVIEW records where auto_approve_at is less than or equal to the current Unix timestamp.

Enqueue release jobs Use Redis, Celery, or scheduled CRON to submit idempotent release_milestone_funds tasks.

Protect payout timing Automatic release prevents stalled reviews from trapping developer earnings after the review window expires.

SELECT milestone_id
FROM milestones
WHERE current_state IN ('SUBMITTED', 'IN_REVIEW')
  AND auto_approve_at <= :current_time;
