At Onchain Bridges, I built and operated Node.js and Express services serving 80,000+ requests per day at peak. I cut p95 latency on the slowest endpoints from 2–3 seconds to under 500ms through query optimization, indexing, and eliminating an N+1 pattern.
I also moved email delivery and report generation into background queues, reducing API response times from 1.5 seconds to under 300ms. I strengthened reliability with bounded retries, idempotency keys, and structured logging.
At Onchain Bridges, I built a cross-chain NFT valuation service that combined semantic retrieval over collection embeddings with market data to produce price bands and LLM-generated rationales. I also developed cross-chain transfer infrastructure using Chainlink CCIP across 10+ EVM chains.
For Front Desk Rx, I built a document-grounded agent with tool-based booking and an evaluation harness; its pass rate rose from 33/50 to 48/50. Earlier, as a Software Engineer Intern at Nokia Bell Labs, I built secure REST APIs and delivered a Digital Twin platform for the Factory in a Box initiative.
