Large-scale community and marketplace development
Grow your business on the power of community
Community and marketplace platform development is the end-to-end build of large-scale community products and marketplaces — membership management, content systems, rankings, and payment integration included. TreeSoop's KAIST- and POSTECH-trained engineers design high-availability architectures that stay stable with tens of thousands of concurrent users, backed by a 4.92/5 rating on Wishket, Korea's largest dev-outsourcing platform.
WordPress, Cafe24, and similar off-the-shelf solutions feel convenient at first — but as you grow, customization limits stack up and migration costs climb sharply.
When an event or viral moment sends traffic surging, the service slows down or goes offline — and the new users you just acquired are gone.
Marketplace payment logic — seller settlement, fee calculation, payment gateway integration, refund handling — is complex to implement and even harder to maintain.
We design your platform on microservices or a modular monolith, so each capability can scale independently as the community grows.
Points, badges, levels, rankings, and notification systems lift community participation and bring users back more often.
We build the full payment infrastructure: integration with Toss Payments, PortOne, and other Korean payment gateways, automated seller settlement, and tax-invoice issuance.
WebSocket-powered live chat, real-time notifications, and activity feeds keep conversations flowing inside your community.
We define the business model, monetization approach, and core user experience, then design the technical architecture.
We build the platform essentials first: sign-up, content creation, and core interactions.
We add gamification, notifications, and recommendation algorithms that drive user participation.
We implement payment gateway integration, seller onboarding, and automated settlement.
Concurrent-user simulation, database index optimization, and CDN configuration lock in service stability.
An education marketplace where instructors publish courses and learners purchase and take them.
A real-estate community platform integrating rental listings, contract drafting, and secure payments — no brokers in between.
A pet-owner super-app combining information sharing, nearby owner matching, pet-sitter booking, and a supplies marketplace.
