I have been working at Airstack since mid 2023. these are some of my work experiences.

Farcaster Indexing & Social Scoring:
Designed and developed the Farcaster Indexer using Hubs, Kafka, ClickHouse, and Go microservices to track protocol events. Extended this to build a Social Capital Score system based on followers and engagement on Warpcast, which powered the $MOXIE incentive program distributing over 2 billion tokens in rewards.

Distributed Chain Indexing:
Led the indexing of chains like Base, Zora, and Gold using distributed systems with Kafka, MongoDB, and Go microservices. Built scalable services such as block-ingester and block-processor for efficient blockchain data management.

Smart Contract Development:
Developed smart contracts for locking fan tokens and distributing engagement-based rewards, contributing to the tokenomics design of on-chain social systems.

AI + Web3 (Eliza Framework):
Contributed to the Eliza AI framework, building skills such as ERC20 sentiment analysis on Base and a PnL calculator using Dune Analytics data to empower on-chain user insights.

I am looking for a web3 career in l1/l2 working on zk solutions, where my contribution can have positive impact the company and the world.
