Built an on-chain ZK-powered Social Deduction Game (MVP) using Circom and zk-SNARKs for private role logic—demoed at EDCON 2025. Optimized gas via off-chain proof generation (Gevulot, Risc0) and efficient on-chain verification. Researched zkSync’s prover stack and designed a threshold-cryptography-based session system for secure, social login-compatible Account Abstraction.
The Social Continent
Sep 202310 mosJun 2024

Built SoCon, a decentralized social identity layer with portable profiles, social recovery, and data ownership—bridging Farcaster & ATProtocol principles. Architecture Protocol (Foundry), P2P node infra, and real-time engagement features. Integrated AI-based interest matching using LLM and scaled via AWS. Designed tokenomics to align incentives for user-owned identity and social graphs. Authored the whitepaper for The Social Continent—A Sufficiently Decentralized solution designed to onboard the next million users.
The Social Continent
Jul 20233 mosSep 2023

Design a smart contract for a complete decentralized social layer that provides users with on-chain identity and enables on-chain verification of off-chain data, establishing a sufficiently decentralized architecture where users are the true owners of their data. Inspired by farcaster and atProtocol (Fund Raises $180M +)

Engineered ( Proof of Concept) a modular and privacy-enhanced DEX protocol focused on user custody, seamless composability, and smart account UX. Integrated zk-SNARK-based Multi-Factor Authentication for secure, private fund access, and Social Recovery for self-custodial key management. Designed ERC20 Vaults and Portfolio ABTs (SBT-powered identity tokens) to unify user asset views across pools and strategies. Enabled gas-optimized vault deployment via EIP-1167 clone factories, and introduced One-Sided Liquidity Provisioning for flexible LP participation without impermanent loss risks. Leveraged Account Abstraction to simplify on-chain interactions and power advanced trading flows through smart accounts. Built withdrawal and interaction logic in Circom for fully private exits.

About

AI/ML & GenAI Engineer focused on building production-grade intelligent systems. I work across the ML lifecycle—from model development and evaluation to deployment, monitoring, and optimization—with hands-on experience in classical ML, LLMs, RAG, AI agents, MLOps, and cloud infrastructure. My recent work includes building LLM-powered agents using LangGraph and Azure OpenAI, production AI/ML systems with FastAPI and MLflow, model monitoring and drift detection, and scalable deployments using Docker, Kubernetes, AWS and Azure. I also have a strong engineering background in distributed systems and Web3/ZK, which gives me a broader perspective on building scalable and reliable products. Focus: AI/ML • GenAI • LLMs • AI Agents • MLOps • ML Systems • Cloud • Production AI
