Skilancer
For v0 builders

Get your v0 app production-ready.

v0 is exceptional at generating polished Next.js UI fast — which is exactly the problem. The frontend looks production-grade, so it's easy to assume the backend, auth, and data layer behind it are just as solid. Often they aren't there yet at all.

What we see in v0 apps every week

None of this means you built it wrong — it means the AI got you to a working prototype, not a production system.

🧩

UI ahead of the backend

A beautiful interface wired to placeholder logic, mock data, or an API that was never hardened for real use.

🔓

No real auth layer

Forms and dashboards that look gated often aren't actually enforcing access control server-side.

📈

Data layer not designed for scale

Whatever backend got bolted on to make the UI functional usually wasn't designed for concurrent real users.

🚨

No one who owns the full stack

Great frontend, thin backend, and no engineer who can responsibly finish the other half.

Quality Above All

Our 4-Stage Senior Vetting Pipeline

We reject 97% of applicants so you never have to gamble your codebase on unproven developers. Read our full vetting standards →

01Top 35% pass

Experience & Background Filter

Minimum 5+ years of shipping production software

We screen past work, verified GitHub repositories, and production systems they’ve built or maintained. No junior developers or prompt-only hobbyists.

02Top 15% pass

Architecture & Security Review

Live technical screening with a Principal Engineer

We evaluate system design, database indexing, auth boundaries, security best practices, and familiarity with AI-accelerated dev ecosystems.

03Top 6% pass

Hands-On AI Rescue Challenge

Fixing a live, messy prototype under pressure

Candidates are given a real-world messy, AI-generated codebase with hidden race conditions, memory leaks, and security holes to triage and repair.

04Top 3% accepted

Communication & Ownership Screen

Clarity, reliability, and business empathy

Technical skills are useless without clear communication. We vet their ability to explain complex problems simply and own deadlines independently.

Proven Track Record

Real AI apps. Real production rescues.

Here is what happens when senior software craftsmanship meets AI-accelerated MVPs. View all technical case studies →

Security & AuthRescue in 4 days

Bolt.new · Next.js · Supabase

Leaked Service Keys & Open RLS in Fintech MVP

The Risk:

A founder built a financial dashboard in Bolt. The client bundle inadvertently exposed the Supabase service role key, and Row Level Security was disabled — allowing anyone to read other users' financial logs.

The Fix:

The matched Skilancer engineer quarantined the exposed keys, migrated database queries to authenticated Server Actions, instituted granular RLS policies, and added integration tests.

100% security vulnerability remediation in 4 days. Ready for SOC2 compliance.
Performance & Scale60% cost cut

Cursor · Node.js · OpenAI · Redis

Serverless Timeouts & 10x Runaway API Bills

The Risk:

An AI document extractor was crashing on Vercel with 30s serverless timeouts. React re-render loops were firing duplicate LLM API calls, generating $4,000 in unexpected weekly OpenAI charges.

The Fix:

Refactored heavy LLM workflows into an asynchronous background queue with Redis & BullMQ, implemented response streaming, and added response caching and token deduplication.

Zero timeout errors, 60% reduction in AI API costs, response time down to 180ms.
Database & Payments99.99% reliability

Lovable · Stripe · PostgreSQL

Duplicate Orders & Checkout Deadlocks

The Risk:

A fast-growing marketplace experienced duplicate order charges and missed subscription upgrades due to non-idempotent Stripe webhook handling and unindexed database queries under load.

The Fix:

Engineered atomic database transactions, added idempotency keys to Stripe webhook handlers, set up PgBouncer connection pooling, and optimized slow Postgres queries with targeted indexes.

99.99% payment processing reliability, DB latency dropped from 1.9s to 22ms.

Every Skilancer engineer goes through a rigorous 4-stage screening: background verification, a live architecture and code-security review, a hands-on debugging challenge on messy/AI-generated code, and communication vetting. We accept only the top ~3% of applicants.

Your v0 app deserves an expert, not another prompt.
