Built and shipped a real-time prediction markets platform, designing backend systems for trading, settlement, and analytics. Designed event-driven architecture using Pub/Sub and multi-worker pipelines (10+ workers) for order execution, retries, and failure recovery. Developed idempotent financial workflows to ensure correctness and prevent duplicate executions in distributed systems. Built real-time pipelines for portfolios, leaderboards, and analytics, handling high-frequency event streams with strict ordering guarantees. Worked on trading infrastructure including orderbooks, RFQ-based matching, and user intent-driven trade discovery. Designed and implemented a high-throughput, scalable key-value lookup system using DynamoDB with parallel batching and concurrency optimization. Led migration from on-chain to off-chain architecture, backfilling blockchain data and ensuring consistency across systems. Built APIs, data models, and backend services for trading flows, onboarding, and wallet-based authentication. Developed admin dashboards and internal tools for managing markets, users, and settlements. Optimized frontend performance for real-time interfaces (orderbooks, dashboards), improving rendering efficiency and UX. Worked on on-chain/off-chain reconciliation, handling latency, consistency, and correctness tradeoffs. Debugged and resolved production issues across backend, frontend, and blockchain layers in a live system. Collaborated on system design for trading infrastructure including matching engines and execution pipelines. Reduced infrastructure costs significantly by refactoring integrations and optimizing external dependencies ($2000 → $250/month).
