DaMeta1 Ecosystem

A global AI-driven Metaverse bridging education and business across 5 continents. Features immersive 3D hubs and decentralized infrastructure.

The Problem

The client needed a cross-continental education and business metaverse with immersive 3D spaces and on-chain identity, without splitting the product across multiple agencies. Coordinating education hubs, marketplace logic, and wallet-based identity across regions required one coherent architecture that a single engineering owner could ship and maintain. Fragmented vendor stacks had already made iteration slow and identity inconsistent.

Tech Stack & Architecture

React frontends with Three.js power the 3D hubs. Web3 wallet and identity layers sit beside modular services for education content and marketplace features. Regional content and identity flows were designed so configuration—not separate codebases—handles multi-region differences. Deployment and ownership stayed under one engineering model rather than a multi-vendor hand-off.

Key Results

Delivered a unified multi-region metaverse platform with immersive 3D hubs, on-chain identity, and modular education and marketplace services. The client gained a single product surface and a maintainable stack instead of disconnected regional builds.

Ordwin Market

High-performance Bitcoin NFT marketplace specialised in Ordinal inscriptions with a focus on speed and secure trading.

The Problem

Bitcoin Ordinals trading required low-latency indexing of inscriptions and a trustworthy listing UX on a chain that does not share Ethereum-style indexers. Existing tools either lagged behind the chain or forced EVM mental models onto UTXO ownership. Sellers and buyers needed listings bound to real outpoints, not approximate address balances.

Tech Stack & Architecture

Next.js and TypeScript power the marketplace UI. A dedicated sync API tracks inscriptions, ownership transfers, and listings using Bitcoin-native data paths. PSBT-oriented listing flows and reorg-aware indexing keep ownership accurate. The system avoids treating inscriptions like ERC-721 transfer events.

Key Results

Shipped a production Ordinals marketplace with dedicated inscription indexing, ownership tracking, and listing flows built for Bitcoin-native performance. Listings stay tied to current outpoints so the UI reflects chain reality rather than stale EVM-style assumptions.

FAST Timetable

Dynamic scheduling platform for university ecosystems. Streamlining student time-management with a responsive, real-time UI.

The Problem

University students needed a clearer, mobile-friendly way to view and plan class schedules. Static PDFs were hard to scan on phones and slow to update when rooms or slots changed. The goal was a lightweight interface that loads quickly and presents hierarchy students can parse in seconds.

Tech Stack & Architecture

React SPA deployed on Vercel with responsive layouts and real-time-oriented UI patterns for timetable browsing. Emphasis on fast first paint, readable hierarchy on small screens, and simple navigation between days and sections without heavy client state.

Key Results

Replaced static PDF schedules with a responsive, mobile-first timetable interface that students can browse and plan around in real time. The product reduced friction for checking the next class and comparing sections on mobile devices.

Soft Stake

DeFi staking architecture with automated yield distribution and secure liquidity pool management for crypto assets.

The Problem

The product needed staking and yield flows users could verify on-chain, with clear distribution logic and a usable web interface for pool interaction and monitoring. Opaque reward math and fragile frontends were common failure modes in comparable products.

Tech Stack & Architecture

Solidity contracts implement staking and yield distribution. Ethers.js connects the frontend to contract state and transactions. A Node-assisted backend supports operational workflows around the pools. UI surfaces balances, APR-oriented stats, and transaction status so users are not left guessing after a confirmation.

Key Results

Launched staking and yield contracts with a clear on-chain distribution model and a usable web interface for pool interaction and monitoring. Operators and users share the same source of truth: contract events and readable dashboard state.

RippleRoot

A premium design-centric platform showcasing collaborative art and wildlife-themed digital experiences for global clients.

The Problem

A creative brand needed a high-end web presence that matched the quality of collaborative art and wildlife storytelling. Motion had to feel intentional—not decorative noise that hurt performance or accessibility on mid-range devices.

Tech Stack & Architecture

Next.js with Tailwind and Framer Motion for motion-rich, design-led pages and responsive marketing layouts. Performance budgets guided animation choices so the site stayed usable on mobile while preserving the brand visual language.

Key Results

Delivered a design-led marketing site with motion-rich layouts that reflect the brand collaborative art and wildlife narrative across devices. The client received a maintainable frontend base rather than a static design export.

DMU Utility Token

The native economic layer for DaMeta1. An ERC-20 smart contract system powering governance and AI-driven marketplace transactions.

The Problem

DaMeta1 required an on-chain economic layer for governance and marketplace settlement tied to the broader ecosystem. Splitting contract ownership from frontend ownership would have slowed iteration and created integration gaps between token flows and product UX.

Tech Stack & Architecture

ERC-20 Solidity contracts on Ethereum with Web3.js integration for governance and marketplace transaction flows. Contracts were wired into existing DaMeta1 frontends so token actions surface in the same product experience users already use.

Key Results

Implemented the ERC-20 economic layer that powers DaMeta1 governance and marketplace settlement, integrated with the broader ecosystem frontends. Governance and market actions share consistent identity and transaction feedback.
