Project details

I will turn an early product idea into a scoped and operable MVP.

Done IT connects product requirements, user flows, Figma UI/UX, frontend, backend, administrator tools, cloud deployment, and QA under one senior owner. This service is designed for founders who need a working launch rather than disconnected design and development files.

The exact feature list is confirmed before implementation. Complex marketplaces, payments, AI workflows, mobile apps, or multi-role products should begin with the Starter product-definition package.

About Kirina

Kirina B.Status: Offline
Senior Full-Stack Product Engineer | Next.js, React Native & Web3
Seoul, South Korea - 11:14 pm local time
I build production-ready web and mobile products that connect complex systems: AI APIs, payments, admin workflows, real-time data, cloud infrastructure, and blockchain networks.

My background combines senior frontend engineering with full product delivery. At Composable Finance, I helped build and maintain multichain products spanning Cosmos, Polkadot, Solana, and Ethereum, including bridge interfaces supporting 21 networks and more than 30 assets. At Netmarble's Metaverse World, I developed DEX, staking, NFT payment, analytics, and admin experiences across desktop, mobile, and embedded webviews.

Through Done IT, I take products from an unclear idea to a working launch. I can handle product requirements, user flows, Figma UI/UX, frontend, backend, mobile packaging, cloud deployment, QA, and operational tools under one consistent product direction.

Relevant delivery experience includes:

• React and Next.js SaaS products, dashboards, marketplaces, CRM, and admin systems
• NestJS, Express, GraphQL, Prisma, Firebase, Supabase, Redis, and external APIs
• React Native and Expo apps for iOS and Android
• Payments, subscriptions, coupons, refunds, OAuth, notifications, and automation
• AI-assisted product features, including a two-week AI MVP launch
• Web3 wallets, DEX, swaps, liquidity pools, staking, NFT payments, IBC, and multichain bridges
• AWS EC2 and S3, CloudFront, Cloudflare R2, GCP, and Azure environments

I have launched 17 products across AI, SaaS, web, mobile, and blockchain. I communicate directly, document important decisions, run at least two rounds of manual QA, and stay responsible through deployment and handoff.

If your scope is still evolving, I can begin with a paid architecture and product-scope milestone. If the product is already in development, I can review the current codebase, isolate the highest-risk area, and ship one end-to-end improvement first.

Tell me what must work in production, what is already built, and where the project is currently blocked.
