Most blockchain projects don't fail because of bad smart contracts, they fail because the frontend can't communicate with the chain reliably, the wallet integration breaks under real users, or the on-chain architecture wasn't designed for the product from day one.
I build full stack blockchain applications where the smart contract logic, Web3 frontend, and backend infrastructure are designed together not bolted together after the fact.
What I've shipped:
ERC-20/721 smart contracts, DeFi protocols, and NFT marketplaces handling real transaction volume on Solana and EVM chains
Full stack Web3 platforms with wallet integrations, token economies, and cross-chain DApp architecture
Blockchain-integrated game systems, on-chain asset ownership, NFT-based progression, and token reward mechanics
React and Next.js frontends for fintech and Web3 products with complex data flows and real-time performance
AI-connected blockchain tools, on-chain automation agents and LLM-connected workflows where relevant
Where I'm strongest:
Solidity and EVM smart contracts built for security and auditability, not just functionality
React and Next.js frontend and backend for Web3 UIs that handle real users
DeFi protocol integrations and NFT platform builds
Blockchain game development, on-chain mechanics, asset systems, and token economies
How I work:
I ask why before I write code. Every architecture decision, chain selection, contract structure, wallet integration approach gets validated against your product requirements before development starts. I've worked with startups, gaming studios, and DeFi teams. I don't just build features, I help you think through the architecture first.
Tech Stack:
Solidity | EVM | Solana | Web3.js | Ethers.js | IPFS
React | Next.js | Node.js | MongoDB | REST APIs
MetaMask | WalletConnect | NFT Standards | DeFi Protocols
OpenAI API | AI Agents | LLM Workflows
GitHub Actions | Performance Optimization
If you need a blockchain developer who understands the full stack from smart contract to user interface, let's talk.

I help startups, founders, and Web3 teams build, deploy, and scale production-ready blockchain systems — from smart contracts and dApp architecture to token launches, liquidity systems, and full Web3 infrastructure.
I don’t just write code. I build and modify real, live blockchain systems that are meant to go to mainnet, scale, and generate usage.
If you need someone who only delivers “MVP demos,” I’m probably not your guy.

40+ AI employees deployed. 10 in my internal fleet. 30+ across 15 client production environments. 99.5% uptime over 12 months.
They research leads, write outreach, publish content, run audits, monitor systems, and report back. Every day. Without supervision. Not chatbots. Employees that do work.
A meta-agent on a single server dispatches tasks across my internal fleet, reviews output quality, and ships me one daily digest. The fleet handles a full sales pipeline (research → qualify → email → LinkedIn DMs), multi-platform content, SEO, job hunting, and proposal drafting.
What I deploy:
AI Sales Teams — Agents that research prospects, enrich with company intel, score against your ICP, then draft personalized cold emails and LinkedIn DMs. 5-touch drip sequences. Rate limiting. Pipeline tracking. Your human reps close. The AI does everything before that.
AI Content Teams — Agents that research daily, draft platform-native content, run it through quality gates that catch AI slop, and publish on approval. I've built pipelines for LinkedIn API, X API v2, and Reddit with content rotation and topic cooldowns.
AI Operations Staff — Health checks, data syncing, scheduled reports, system monitoring, compliance audits. They follow the process exactly, every time, and flag when something's off.
Fleet Orchestration — When you have multiple AI employees, you need a manager. I build meta-agents that coordinate your fleet, dispatch work, evaluate output, and deliver a single daily digest of everything your AI workforce accomplished.
Verticals shipped: tax firms (6-agent IRS forms / TaxDome / bookkeeping swarm), digital ad agencies (30+ accounts across Google Ads / GA4 / Meta / LinkedIn), DTC supplements (3-agent brand intelligence in UK / US / AU markets), home-services operators (CRM + SMS booking + browser automation), B2B SaaS dev teams, prediction markets, newsletters, lead generation.
Why clients keep me on retainer:
I operate, not just build. Most freelancers hand you a bot and disappear. I deploy on production infrastructure with health monitoring, auto-restart, secret management, and audit trails. I keep them running.
I've done it for myself first. My own business runs on AI employees. Lead research, outreach, content, SEO, proposals. Every system I sell to clients, I've battle-tested on my own operations.
I know what breaks. 40+ deployments taught me where agents fail: config coupling, context overflow, token expiry, rate limits, memory drift, browser session decay, OAuth refresh races. I've hit every failure mode and built recovery into the infrastructure.
You're paying humans to do work that follows a process. I deploy AI employees that do it faster, cheaper, and without taking weekends off.
Send a message with the repeating process you want owned. I'll tell you in 24 hours if it's a fit.

𝐄𝐱𝐩𝐞𝐫𝐭-𝐕𝐞𝐭𝐭𝐞𝐝 (top 1% on Upwork) and 𝐓𝐨𝐩 𝐑𝐚𝐭𝐞𝐝 𝐏𝐥𝐮𝐬, with $𝟒𝟎𝟎𝐊+ earned across 𝟏𝟐𝟓+ projects. I'm a founder and full-stack engineer who acts as your technical partner, architecting AI and blockchain systems that work in production, not just in a demo.
Most clients come to me when the build actually matters: when it has to be secure, has to scale, and has to handle real data or real money without breaking. I architect and build custom systems end to end, and I can bring in a vetted team when a project needs more hands. Think of me as a fractional CTO and a builder in one: senior judgment on the strategy, real hands on the code.
A lot of AI talent stops at a clever prompt and a slick demo. I come at it as a systems engineer. I have architected a Layer 1 blockchain hardened with post-quantum cryptography, a decentralized exchange and validator platform, an on-chain tokenization system for commercial real estate, and production AI agents that run real sales and operations workflows. I work natively in fintech and regulated systems, so I'm as fluent in tokenomics, compliance, and data-heavy infrastructure as I am in the code itself. If your AI or your protocol has to be correct, not just impressive, that is the gap I fill.
𝐖𝐇𝐀𝐓 𝐈 𝐁𝐔𝐈𝐋𝐃
• AI agents and automation: multi-agent systems, LLM integration, RAG, and automation wired into your real tools and data

Hi, I'm Kaushik — a full-stack and React Native engineer who builds SaaS products and marketplaces, and fixes the ones that broke on the way to launch. If your app is stuck, half-built, or quietly falling apart in production, I can tell you why and make it right.
8+ years in, most of my work is one of two things. Either a founder has an idea and needs it built properly the first time — the database, the payments, the mobile app, the admin side — without it collapsing the moment real users arrive. Or someone already has a product, often started by another developer or an AI tool, that almost works but can't be trusted, and they need someone to take it over and finish it honestly.
I've done both ends of that. I built VNYX, a multi-tenant SaaS platform that resale businesses use to grade products, generate listings with AI, and sync them across marketplaces like Shopify and eBay — where multiple businesses run on the same system and none can ever see another's data, isolated on every request through a five-tier role hierarchy. And on PepsiCo's MiNegocio+, a B2B ordering platform live across 8 countries for a Fortune 50 company, I worked on React Native apps that had to keep working with no signal at all — distributors placing orders offline and syncing cleanly on reconnect, with no duplicate or lost orders.
My stack is React, Next.js, Node, and TypeScript on the web, React Native on mobile, with Postgres, Supabase, and Stripe underneath. I lean on AI tools like Claude Code to move quickly — and I read every line they write, which is exactly why I'm comfortable cleaning up a codebase one started.
What you're really hiring is someone who'll tell you the truth about your product, build it to survive growth, and still be around after it ships. If that's what you need, tell me what you're working on and where it hurts.
