Electron Desktop Application Seems that my project was taken on without possessing the skills required to fulfill the requirements, though during the initial interview every item/requirement I had was responded with "Yes not a problem".
Finally, after paying for 3 milestones (Yes, this is my fault and I accept it) eventually I never received a response to my next meeting date request (which was in April 2024).

Money down the drain for me - it happens. I get wanting to take on a job for the money but for me, shelling out thousands on something that in the end was never going to be able to be completed due to the lack of skills while being assured it was all perfectly doable is frustrating.

AI/Web dev needed for ai powered newsletter Asked for an ai powered newsletter that could parse and scrape together data to then be organized and displayed and give users a wide sweeping overview of all news and data relating to crypto. I got an expensive ai powered scraper that copy and pastes blog posts. It's my own fault for being unable to very clearly and accurately describe what was in my mind. I just expected a bit more after the lengthy discussions regarding the idea to flesh it all out.

Blockchain & AI Engineer | Smart Contracts, ZK Proofs & AI Agents

Gandhinagar, India - 5:52 am local time
I build production blockchain and AI systems that ship: Solidity smart contracts, zero-knowledge proofs, and AI agents. 8+ years in software, 5 focused on Web3 and cryptography, with 25 completed Upwork jobs, 1,890+ hours, protocols in production, and ETHGlobal hackathon wins.

I care about the things that actually matter to clients: clean, tested code, clear communication, and hitting deadlines. I can own a feature end to end, or drop into an existing codebase and be useful in the first week.

What I can help you with:

• Smart contracts (Solidity): ERC-20/721/1155 tokens, staking, escrow, vesting, DeFi mechanics, account abstraction and modular accounts (ERC-4337, ERC-6900). Built with Hardhat and Foundry, tested and gas-conscious.
• Zero-knowledge proofs: ZK circuits and verifiers in Noir and Circom, privacy-preserving flows, proof-of-personhood, verifiable credentials, selective disclosure.
• AI agents and LLM integration: autonomous agents, tool use, agent identity and authorization, RAG and API integrations, and agentic development (I build with Claude Code daily).
• Full-stack dApps: React, Next.js, Node.js, TypeScript, wagmi/viem/ethers, wallet integration, IPFS, The Graph.
• Smart-contract review and hardening: a second set of eyes for common vulnerabilities and gas issues.

Recent work:

• Built escrow and bounty smart contracts plus a GitHub App for tea.xyz, and shipped an ERC-6900 module that secured an official listing.
• Architected privacy-preserving DeFi and ZK anonymous voting at Sacred Protocol over 4 years.
• Won at ETHGlobal New Delhi 2025 and an IPFS/Filecoin bounty; maintain open-source tools including a package with 350k+ downloads.

Tech: Solidity, Hardhat, Foundry, OpenZeppelin, EVM L2s, Noir, Circom, zk-SNARKs, ERC-4337/6900, IPFS, TypeScript, JavaScript, React, Next.js, Node.js, NestJS, wagmi, viem, ethers.js, GraphQL, PostgreSQL, MongoDB, Supabase, Docker, AWS, GCP.

How I work: clear scope up front, regular updates, and code your team can maintain. Responsive across time zones, and happy to start with a small paid test task so you can see how I work before committing to more.

Send me a message with what you are building, and I will tell you honestly whether I am the right fit and how I would approach it.
