Our Services

From custom software, AI, and automation to smart contracts and blockchain platforms, we deliver production-grade technology across every layer.

Smart Contract Development

We write production-grade Solidity smart contracts for ERC-20 tokens, ERC-721 and ERC-1155 NFTs, staking, yield farming, vesting, and governance. Our contracts are gas-optimized, upgradeable, and tested against real-world attack vectors.

Smart Contract Auditing

Protect your protocol with a security-first review of your smart contracts. We identify vulnerabilities, verify access control, test edge cases with fuzzing, and deliver a prioritized remediation report before your mainnet launch.

DeFi Protocol Development

We engineer lending and borrowing platforms, DEXs with automated market makers, yield aggregators, and cross-chain DeFi applications with integrated wallet connectivity and subgraph indexing.

Blockchain Infrastructure

From custom EVM networks with PoA or PoS consensus to Layer 2 deployments, block explorers, faucets, and node infrastructure, we build the scalable foundations your Web3 product needs.

Web3 Consulting

From tokenomics design and chain selection to architecture reviews and go-to-market strategy, our consultants help founders make technically sound decisions before committing engineering budget.

dApp & NFT Development

We build responsive Web3 frontends, NFT marketplaces, minting sites, and Telegram mini-apps with wallet login, real-time data, and a user experience that attracts non-technical users.

Custom Software Development

End-to-end custom software: architecture, backend, frontend, and databases for production-grade web and cloud applications built for scale, with automated testing and CI/CD included.

AI & LLM Solutions

Production-ready AI applications powered by LLMs: custom AI agents, RAG pipelines, semantic search, fine-tuned models, and AI chatbots deployed on websites, WhatsApp, Telegram, and Slack.

n8n Workflow Automation

Custom n8n workflows and business process automation that connect your apps, sync data, route leads, and eliminate manual work — with error handling, retries, and logging you can trust.

Cloud & DevOps Engineering

Cloud architecture, CI/CD pipelines, Docker and Kubernetes, infrastructure-as-code, monitoring, and cost optimization on AWS, GCP, and Azure to keep your systems reliable and fast.

APIs, Web & Mobile Apps

Clean REST and GraphQL APIs, Stripe and third-party integrations, and cross-platform iOS and Android apps with React Native and Flutter — from design to app store deployment.
