Services I Offer
Production-grade engineering across Web3, MERN, and AI — built on 6+ years of experience and 50+ shipped projects for 25+ clients globally.
Web3 & DApp Development
End-to-end decentralized application engineering — token presales, staking platforms, DAO governance, NFT marketplaces, and DeFi launchpads.
- ▸Token presale + ICO launchpads
- ▸Staking platforms with daily reward distribution
- ▸NFT minting, marketplaces, lazy minting
- ▸DAO governance contracts + voting frontends
- ▸Cross-chain integrations (Ethereum, BNB, Polygon)
Deliverable: Audited smart contracts, deployed on testnet + mainnet, integrated frontend with wallet UX (MetaMask, WalletConnect), full documentation.
Smart Contract Engineering
Solidity development with security-first patterns. Reentrancy guards, gas optimization, upgradeability where appropriate, OpenZeppelin standards.
- ▸ERC-20, ERC-721, ERC-1155 token contracts
- ▸Staking, vesting, and timelock contracts
- ▸Custom DeFi primitives — AMMs, lending pools, oracles
- ▸Pre-audit hardening and remediation
- ▸Hardhat + Foundry test suites with > 90% coverage
Deliverable: Source code in a Hardhat or Foundry repo, full test suite, deployment scripts, gas report, and a security checklist signoff.
MERN Full-Stack Engineering
React, Next.js, Node.js, MongoDB. From SaaS dashboards to e-commerce, real-time apps to admin tools.
- ▸Next.js 14 App Router apps with SSR/ISR
- ▸Custom REST and GraphQL APIs
- ▸MongoDB / PostgreSQL schema design + indexing
- ▸Authentication (NextAuth, Clerk, custom JWT)
- ▸AWS, Vercel, Docker deployments + CI/CD pipelines
Deliverable: Production-deployed app, repo with README + setup, environment templates, and a runbook for the ops team.
AI Automation & Agents
N8N workflows, OpenAI / Claude integrations, custom AI agents that automate real business processes — not demos.
- ▸N8N workflow automation (CRM, email, data pipelines)
- ▸OpenAI / Claude / Anthropic API integration
- ▸Custom AI agents with tool use + memory
- ▸Prompt engineering and evaluation harnesses
- ▸RAG pipelines and embedding-based search
Deliverable: Deployed N8N instance or AI agent backend, with monitoring, prompt versioning, and a non-engineer-friendly admin UI.
Frequently asked questions
How long does a typical Web3 project take?+
Most token presale or staking platforms ship in 2-4 weeks end-to-end. Larger DeFi protocols or NFT marketplaces take 6-10 weeks. I always quote a fixed scope per milestone so you can pause between phases.
Do you write the smart contracts and the frontend yourself?+
Yes. I deliver the deployed Solidity contracts, the React/Next.js frontend, the wallet integration (MetaMask, WalletConnect), and the deployment pipeline. One engineer, one accountable deliverable.
What's your stack for MERN projects?+
Next.js 14 App Router on the frontend, Node.js + Express or Next.js API routes on the backend, MongoDB or PostgreSQL for persistence, NextAuth or Clerk for auth, and Vercel or AWS for deployment. CI/CD via GitHub Actions.
How do you charge?+
Fixed-price per milestone for well-scoped work, hourly retainer for ongoing partnerships. Most clients prefer milestones — clearer budget, fewer surprises.
Can I see code samples or audited contracts?+
Yes — I share GitHub links to relevant past work after a 30-minute scoping call. Some client work is under NDA, but I always have public examples in each stack.
