Freelance Marketplace Platform Launched in 8 Weeks
A full-stack freelancer marketplace with escrow payments, live bidding, dispute resolution, real-time chat, and Flutter mobile apps — built from scratch and shipped on schedule.
A founder wanted a Fiverr alternative — built to own
Our client was an entrepreneur launching a niche freelance marketplace for a specific professional category. They needed the full platform — web app, mobile apps, payment infrastructure, and moderation tools — delivered fast and on a fixed budget.
We designed and built a marketplace with dual-sided search, a gig catalog, competitive bidding on jobs, milestone-based escrow, and live chat. Mobile apps on both iOS and Android launched alongside the web platform.
Core product message: A complete freelance marketplace with the trust infrastructure of Upwork — without the 20% platform fee.
Building a trusted two-sided market from zero
A freelance marketplace only works when both buyers and sellers trust the platform. The client needed trust infrastructure — escrow, dispute resolution, identity — alongside the core marketplace features, all within an 8-week delivery window.
A complete marketplace with trust built into the architecture
We built the platform in structured sprints with a Laravel API backend, a web frontend, and Flutter mobile apps in parallel. Every feature was scoped to the delivery date — no scope creep, no last-minute surprises.
Escrow logic runs entirely server-side through Stripe Connect. Funds are held at payment, released on buyer approval, and returned via a reversible refund flow. The dispute system freezes fund state immediately on filing and routes to admin review.
Platform Features
Laravel API + Flutter apps + real-time chat
Laravel handles the REST API, business logic, and background jobs via queue workers. Pusher drives real-time messaging with presence channels for online indicators and typing state. Flutter apps consume the same API as the web client.
The wallet system tracks balance via double-entry ledger transactions — every credit and debit has a corresponding audit record. Withdrawals trigger Stripe payouts with bank account verification enforced before first withdrawal.
Hard problems, solved cleanly
Escrow Payment Lifecycle
Designing a trustworthy flow where funds are held, released on delivery approval, and refunded cleanly on dispute. Built on Stripe Connect with server-side state transitions tied to job status.
Bidding Concurrency
Multiple freelancers bidding on the same job simultaneously required atomic reads and optimistic locks to prevent race conditions when a client accepts a bid.
Real-Time Chat at Scale
Pusher-backed live messaging between buyers and sellers with offline notification fallback. Message delivery receipts and typing indicators required careful event deduplication.
Dispute Resolution Workflow
Structured dispute flows with evidence upload, timeline freezing, and admin adjudication. All state transitions are logged immutably so every decision is auditable.
Dual-Sided Search & Discovery
Buyers need to find freelancers by skill and rating. Freelancers need to find jobs by category and budget. Two separate search contexts sharing one indexing layer.
A live marketplace with 500+ freelancers in production
The platform launched on schedule after 8 weeks of development. Over 500 active freelancers onboarded in the first months of operation. The escrow system processed real transactions from day one with no payment disputes going unresolved.
The client now owns the platform outright — no revenue share, no vendor lock-in, no per-transaction fees to a third-party marketplace. The architecture supports adding new job categories, payment methods, and geographies without rebuilding.
Questions about building a freelance marketplace?
Common questions from founders before starting a marketplace engagement.
A full-featured freelance marketplace — with bidding, escrow payments, live chat, dispute resolution, and mobile apps — typically ranges from $25,000 to $70,000. Scope and third-party integrations are the main drivers. We work on fixed-price contracts with a committed scope before we start.
