Hello, I am excited about the Tirios initiative and the opportunity to contribute to next-gen Web3 real estate. I bring hands-on experience with Solidity, Hardhat, Ethereum/Polygon, and building scalable smart contract suites for NFT marketplaces, staking mechanisms, and cross-chain integrations. I can design and implement secure, gas-efficient contracts, integrate them with frontend stacks (React/Next.js/Three.js), and contribute to testing, audits, and DevOps pipelines. I am comfortable collaborating with multidisciplinary teams and shipping full-stack features end-to-end, including governance tooling and analytics. I estimate an initial contribution to your MVP could be delivered within 4–6 weeks depending on feature complexity.

Good day!
I am Valentin from Arctic Web. We are engaged in IT consulting and full-cycle development: from UX/UI design to web and mobile development and integrations. We are ready to take your project into work and share examples of similar cases in personal messages.

Sincerely,
Arctic Web Team

Hello
Ready to collaborate - I have already worked in a similar field. Extensive experience in project management, including writing Technical Specifications (TS), testing, selecting and working with designers and developers to achieve the desired results for you. I am confident that I can help you) The cost is hourly.

Experience as a Project Manager in website and mobile application development (plus advertising) for over 8 years (4 years in the office and now over 4 years remotely).

I am in the TOP - 1 as a technical writer
In the TOP - 2 in project management
In the TOP - 8 in testing

… I am ready to assist in client management, task setting for developers, testing, documentation writing, prototyping, and consulting not only on general issues but also on development stages.

Hello! I’ve reviewed your project requirements as well as the GoldenCity document you attached , and I’m fully prepared to take on the development of the platform across the entire stack — from blockchain architecture and smart contracts to 3D front-end development, AI modules, APIs, and full DevOps infrastructure.

Your project aligns very closely with my experience building decentralized platforms, NFT-based ownership models, cross-chain systems, and high-performance Web3 applications. I can design and implement the smart contract layer (Ethereum/Polygon) for property tokenization, ownership transfer, leasing logic, staking, cross-chain events, and governance. I also focus heavily on gas optimization, upgradeability, and security — which you explicitly emphasize in the role description.

On the front-end side, I can deliver an immersive, high-performance interface using React/Next.js, Three.js/WebXR for 3D interactions, wallet integrations (MetaMask, WalletConnect), dark/light modes, filtering, property walkthroughs, user dashboards, and transaction history — fully aligned with the UI/UX + Frontend scope described on pages 4–6 of your document .

For the back-end, I’ll build a modular microservice architecture using Node.js + FastAPI, with clean REST APIs for properties, users, transactions, ownership, and analytics. I’ll integrate PostgreSQL/MongoDB, S3/IPFS for 3D assets, secure authentication (OAuth2/JWT/Web3 login), logging, health checks, and distributed event handling. This matches your Backend and DevOps sections (pages 6–8) where cloud-native scalability, monitoring, CI/CD, and infrastructure automation are required.

I also cover the AI/ML features you listed — personalized recommendations (LightFM), price predictions, natural-language search (LangChain + LLM), and fraud detection. I can deploy these models through FastAPI + AWS SageMaker exactly as outlined in your document’s AI/ML section (page 7) .
…
For deployment, I’ll prepare a full AWS environment (EC2, Lambda, RDS, SageMaker, CloudWatch), Docker containers, Terraform automation, CI/CD pipelines, staging & production environments, and full test coverage — including performance testing for 3D load times, API latency, and blockchain confirmation times.

I’m ready to collaborate closely with your team, propose the full system architecture, break the build into clear phases, provide demos from my previous Web3/AI/3D projects, and deliver a production-ready platform with long-term support

Good day! I am ready to complete this project. Extensive experience in developing various applications.

Hello!

My name is Ruslan, and I’m a Backend Developer (Node.js / NestJS / TypeScript) with hands-on experience building scalable backend systems, integrations, microservice logic, and working with complex third-party APIs. I work both on classic web applications and advanced platforms involving chats, admin dashboards, video services, CDN, authorization flows, scoring systems, ranking mechanisms, queues, and background processing.

My Technical Background
Node.js, NestJS, TypeScript — strong expertise
MongoDB/Mongoose, Redis (BullMQ / ioredis)
API-first architecture, REST, WebSockets
JWT, refresh/access tokens, OAuth2 (Google Login), role-based auth
… Video integrations (Vimeo API), Cloudinary, webhook processing
Modular architecture, DTOs, Pipes, Guards, Interceptors
Docker, Docker Compose, deployments on Vercel, Railway, Render, Hetzner
Close collaboration with frontend teams, Postman collections, API documentation
PayloadCMS (extensions, custom collections, backend integration)
In my previous projects, I’ve implemented:
ranking, scoring, and voting systems
background workers and queues through Redis
video processing with webhooks, event listeners, and automation
Google OAuth popup flow
large-scale admin panels with custom business logic
complex backend modules (Collections, Hire-CTA, Chat, PopularQueue)
Why I’m Interested in Your Project
Web3, real estate tokenization, NFT infrastructure, and blockchain-powered platforms are exactly the direction I want to grow in. I already have a strong backend foundation and can quickly dive into Solidity/Hardhat and blockchain architecture — especially where backend interacts with smart contracts, indexing services, cross-chain events, and real-world assets.
I have extensive experience delivering production-ready logic, optimizing performance, writing scalable API layers, documenting systems, creating tests, and working closely with frontend teams to ensure features work flawlessly in real user scenarios.
What I Bring
strong backend fundamentals for your Web3 platform
reliability, ownership, independence, and fast learning
deep experience with scaling, security, data modeling, and high-load patterns
a user-centered mindset — delivering value first, then optimizing everything else
I would be glad to discuss collaboration and walk you through some of the features I’ve built.
I’m ready for the technical interview and excited to go deeper into the blockchain direction.

Thank you for your time!

Good evening, you have a very interesting project. If you need an experienced web3 marketer, I would be happy to help) I have my own database of influencers, an understanding of how to build a quality strategy, and how to launch social media from scratch.

Hello, Benoit
Thank you for sharing the detail about GoldenCity
I have read your document and requirement carefully and understood all.
As a full stack blockchain developer with proven experience in blockchain development including NFTs based on multiple blockchain networks such as EVM and SVM, I am very confident.
Additionally, I have also experienced in Three.js.
If you check my work history here, you will see my expertise in blockchain development.
I'd like to discuss with you.
Thank you.

… Best regards,
Vladislav G

Hi Benoit Cabello,

I’m excited to apply for the Blockchain Engineer role. I build full-stack Web3 apps with React, Next.js, Node.js, and modern Ethereum tools. I enjoy turning complex blockchain ideas into clean, secure, and fast user experiences.

I have strong hands-on experience with Solidity, Hardhat, Polygon/Ethereum, and writing gas-efficient, upgradeable contracts. I’ve worked on NFT drops, staking flows, and cross-chain events. I’m comfortable owning features end-to-end—from smart contract design to frontend integration and API work.

On the frontend, I build responsive UIs with React/Next.js and have worked with Three.js for 3D scenes. On the backend, I work with Node.js and FastAPI to create stable APIs and services that support real-time blockchain events. I also handle CI/CD, testing, and DevOps tasks to keep systems reliable.

I like working with teams that move fast, communicate clearly, and care about the product. Real-estate tokenization and the future of Web3 ownership are problems I want to help solve, and Tirios is doing important work in that space.
…
Thank you for your time. I’d love to contribute to Protofire and help build the next generation of Web3 real estate.
