Absinthe Labs
Software Engineer · May (Present) (2025)
- Led development of Absinthe Adapters, a scalable multi-chain indexing platform (Morpho V1/V2, Uniswap V2/V3, Orca) for transactions and time-weighted balances, serving live customers in production.
- Optimized Orca indexer by replacing O(n×m) transfer scans with an event-driven pipeline (Mint-Tracker + Transfer-Watcher + external indexer), significantly reducing CPU usage and enabling near real-time indexing.

- Architected SybilGuard, a soulbound NFT-based reputation system using EIP-712 voucher signing, backend scoring (17+ signals), and full-stack minting flows with minimal on-chain state.
- Worked as a Forward Deployed Engineer, partnering with customers on live campaigns; built self-serve data and campaign flows enabling teams to configure tracking without engineering support.
- Built scalable identity backfill pipelines (PostgreSQL) using Union-Find for identity stitching, streaming/keyset reads, batched writes, and idempotent CLI tooling, enabling reliable large-scale backfills (incl. SybilGuard scoring).
